The concerns of the UKNB that the text for ISO/IEC 14496-1 Amendment 5 and 15444-3 Amendment 1 may diverge as the different WGs handle NB comments were note. It was decided that the SC29 AGM chairman monitors the processes of generating DoCs to NB comments and amending the text to ensure the text continues to be unified. The changes proposed at the WG1 meeting in Genoa should be reviewed by MPEG in the Fairfax, VA meeting and then returned to WG1.

9.11 Advanced Video Coding The JVT did not meet at the same place as MPEG. However, some documents were produced and communicated to the JVT:
Requirements for AVC Codec 4672Communication to JVT 4673Initial Memory Complexity Analysis of the AVC Codec N4570
4
Guidelines and work-plan for the complexity analysis of the AVC reference software N4571
A Liaison to VCEG (N4658) was also produced to highlight areas of common interest that are not directly dealt with by the JVT.Not having received comments fron NBs, the reference software copyright license of resolution 8 of the Pattaya meeting was adopted. Noting the concerns of several NBs with respect to the royalty-free baseline profile, whose use could be jeopardised by the later appearance of one or more IPR elements with possible negative effects not only the royalty-free baseline, but also other higher-level non-royalty-free profiles, MPEG members – including JVT members – and NBs were requested to take into consideration the consequences of this possible outcome and advise at the next meeting.
9.12 Explorations 9.12.1 Fine Granularity Scalability
It was agreed that work on extensions on top of the Fine Granularity Scalable (FGS) Profile could be started if the advantage of FGS is evident from the finalized test report. Some proposals were received and reviewed. The main goals are 1. higher coding efficiency of FGS coding (prospectively approaching the compression
performance of single-layer coders) 2. extenion of the ranges of scalability.

15.2 Promotional activities New versions of the MPEG-4 and MPEG-7 overviews were approved.
MPEG-4 Overview 4668MPEG-7 Overview 4674
As usual there were an MPEG101 session on the Sunday before the meeting and a sessions related to the establishment of the MPEG-7 Alliance.In addition the SNHC group reported the emerging discussion to initiate an industry forum regarding MPEG-4 AFX standardization. This activity, designed to accelerate the AFX commercialization, will hold a meeting on May 4 before the MPEG (Fairfax) meeting.
16 Organisation of this meeting
16.1 Tasks for subgroups These were assigned. In particular the Convenor asked to collect available information on those assets – conformance bitstreams and reference software – that the group had produced over the years. Jean-Claude Dufourd was kind enough to search for the information and produced N4690 listing the material related to MPEG conformance test bitstreams and N4691 listing MPEG reference software. Similarly it was possible to produce the list of MPEG standards finally released by WG11 for which publication stage had apparently not been reached (N4595).

Annex 4Requirements report
Source: Fernando Pereira (Instituto Superior Técnico) and Keith Hill (Rightscom) for MPEG-21
For the Requirements group, this meeting was marked by the absence of Rob Koenen, following his resignation after about six years as Requirements chairman. Fernando Pereira was appointed as Requirements chairman at the end of this meeting.The activities under the Requirements group’s responsibility were divided between Fernando Pereira (MPEG-4, MPEG-7 and Exploration issues) and Keith Hill (MPEG-21). The Requirements group was in charge of compiling the document including all communications from MPEG to JVT (N4673). This document included communications from the Requirements, Video, Systems and ISG MPEG groups.

MPEG-4 SystemsProfiling
M8045 Riitta Vaananen, Giorgio Zoia, Corrections to 3D Audio profile in MPEG-4 SystemsN4669, MPEG-4 Profiles under ConsiderationThe contribution above was addressed but not discussed in detail since the authors were not present at the meeting. At was highlighted that profiles cannot be ‘corrected’; only technical errors in tools may be corrected. New needs in terms of profiles have to be solved by defining new profiles. Regarding the long standing issues on Scene Graph profiles it was decided: Add some Flextime nodes to Advanced2D profile AdvancedMain2D profile removed from the MPEG-4 Profiles under Consideration document
since its application domain may be addressed with the Main 2D profile Quantization node added to Main2D profile and differently constrained in terms of Levels
Advanced Text and 2D Graphics
M8007 Yuval Fisher, Alexandre Cotarmanac’h, Cyril Concolato, Report of AHG on Advanced Text and 2D Graphics M8210 Vladimir Levantovsky, Application Analysis and Requirements for Advanced Text SupportN4705, Preliminary Call for Proposal on Advanced Text and 2D Graphics Acknowledging the limitations of MPEG-4 technology in terms of text representation, and following the work of the AHG on Advanced Text and 2D Graphics, the requirements on Advanced Text & 2D Graphics (ATG) were reviewed in a joint meeting with the Systems group. It was decided to issue a Preliminary Call for Proposals at this meeting and a Final Call for Proposals at the next meeting, targeting the evaluation of the answers in Klagenfurt, in July 2002.
JVT
N4714, Proposed guidelines for the carriage of AVC content within MPEG FrameworkFollowing the recognition, that the definition of requirements for the Carriage of AVC Content has become important, the following requirements were defined in a joint meeting with the Systems and Video groups: MPEG-4 Systems MP4 File Format Additional on File Format Carriage over MPEG-2 Systems
36
Interchange Carriage over IP Payload Format Additional on Payload Format
These requirements were included in the document with the Requirements for the AVC Codec (N4672). Moreover some guidelines for the development of solutions for the carriage of AVC content were discussed which were included in a document to be issued by the Systems group.
MPEG-4 VisualAdvanced FGS
M8003 Weiping Li, Fine Granularity Scalability for MPEG-4 Part 10 As for last meetings, the possibility to initiate an activity targeting the improvement of the FGS tool was
discussed. Following a proposal to initiate this activity in the JVT, the group decided that FGS on top of AVC may be considered for JVT phase 2 (since scalability is a functionality to be addressed in JVT phase 2) but it still too early to start technical work for phase 2. Moreover the group decided that if the conditions set to start technical work on advanced FGS were fulfilled, this work should start targeting the possible standardization of an ‘advanced FGS' tool on top of MPEG-4 Part 2 video. The conditions were: Meaningful verification test results for the FGS profile Technical evidence of significant possible coding efficiency improvements Availability of reference software for the FGS tool Conformance testing for the FGS tool defined
Since the first condition was not fulfilled by the end of the meeting, the Requirements group did not issue any recommendation regarding the start of advanced FGS technical work.Finally, the close relation with the activities regarding inter wavelet coding in terms of scalability was noted; as a consequence, the definition of similar testing and development conditions was recommended in order to allow more meaningful comparisons to be made.
JVT
M8150 Gary Sullivan, Ajay Luthra, and Thomas Wiegand, Report of the Second Meeting of the Joint Video Team (JVT) of ISO/IEC MPEG and ITU-T VCEG M8159 Korean NB position, JVT 2nd phase functionalities and scheduleM8127 Sherman (Xuemin) Chen, José Roberto Alvarez, Alexander (Sandy) MacInnis, TV Profile for AVC VideoÑ4671, Procedure to Develop Profiles and LevelsN4672, Requirements for AVC CodecN4673, Communication to JVTIn a joint meeting with the Video group, the JVT report from its Geneva meeting in February was reviewed. Moreover the JVT document on Profiles and Levels was reviewed. Regarding the development of profiles and levels, the Requirements group decided to recommend JVT to use the following approach:1. Profile proposals are collected, through the following list of items for each profile: Applications areas (notably new ones, that are enabled by the proposed profile); List of functionalities, compared to the closest existing profile(s); List of tools in the profile; Supporting companies; notice that these companies are also committing to doing the
conformance testing. 2. When a proposal is mature, a decision will be made about its inclusion in the standard. Such a choice will be made on the basis of the following criteria: Identified functionality is not supported by already existing profiles with an acceptable level of
complexity; Avoid to name the profiles using names of applications
37
The added functionality provided by a new profile (e.g. increased efficiency) may involve the performance of verification tests, notably subjective testing.
Declared interest exists in the actual deployment of the profile (or level) in services and products by several companies;
Level definitions available, if levels will have to defined; Streams available to exercise all tools in the profile and the full complexity of the levels (if
relevant); These streams have been checked by multiple, independent parties.
Some additional recommendations regarding the JVT Profiles and Levels are included in the document Communication to JVT (N4673). Among them it is important to highlight the one recommending JVT that complexity analysis be used in order to define the minimum possible number of profiles. The fact that JVT is already mentioning 12 levels for each profile was considered negative.The proposal for a AVC TV profile was reviewed and discussed. The group agreed that profiles should not be named with names of applications to avoid creating the idea that a certain profile is only for a certain application or that other profiles cannot be used for that same application. Moreover it was clear that the exclusion of certain tools from a certain profile had to be motivated using a solid complexity analysis which was requested to the proponents of this profile.
MPEG-4 AudioProfiles & Levels
M7872 Fernando Pereira (editor), Levels for MPEG-4 Audio Profiles M7881 Liaison Statement from MPEG-4 Industry Forum to WG 11 on MPEG-4 Audio Profiles (SC 29 N 4595)N4670, Levels for MPEG-4 Audio ProfilesRegarding the liaison statement from M4IF, MPEG reinforced that always welcomes proposals that address industry needs. However regarding the definition of conformance at the object type level to allow the use of a single object, the Requirements and Audio groups jointly meeting stressed that the same effect may be reached by defining a profile including a single object type and a level with a single object.The document ‘Levels for MPEG-4 Audio Profiles’ was reviewed and approved as public output document to provide a well structured and easy to find collection of audio levels for people outside MPEG.
Lossless Audio Coding
M7955 Takehiro Moriya, Report of AHG on issues in lossless audio coding M7956 Takehiro Moriya, Akio Jin, Lossless scalable audio coding based on MPEG-4 standard M7975 Toshiyuki Nomura, Yuichiro Takamizawa, Evaluation results of scalable lossless coding based on AAC Following the discussion at previous meetings, the Requirements and Audio groups jointly meeting, reviewed the contributions above and concluded that the conditions set for the starting of a technical activity on audio lossless coding, notably Relevant applications identified Industry need shown Commitment by MPEG members made Technical evidence provided
were adequately fulfilled. In this context, an AhG was created with the task to elaborate the requirements for this technical activity and prepare a Call for Proposals to be issued maybe already at next meeting.

MPEG-7
MPEG-7 ProfilingM7917 Wo Chang, MPEG-7 Interoperability Test Bed (M7ITB) M7918 Wo Chang, Yoshiaki Shibata, MPEG-7 Profiles and Levels Architecture M8038 (also 8160, 8208) Eric Rehm, MPEG-7 Profiles and Levels using XML NamespacesM8109 Peter van Beek, M. Ibrahim Sezan, A User Description Profile for MPEG-7 and TV-AnytimeN4678, MPEG-7 Profiles under ConsiderationThe contributions above were presented in a very lively joint session with the MDS, Audio and Video groups. It was stressed that the discussion on MPEG-7 profiling has been around for a long time now and the appearance of the more applications and prototypes should allow a better understand of the need and meaning of profiling in MPEG-7. Major questions discussed were: Why do we need profiles ? What type of interoperability do we want ? Do the answers to these questions depend on the application domain ?MPEG experts will applications in mind were requested to answer to the following questions: Why do you need profiles ? What you happen if you could not have profiles ? What type of interoperability do you want to reach with similar MPEG-7 enabled applications?One outcome of this discussion is the fact that the meaning of interoperability and profiling seems to be different for different application domains, database retrieval and video surveillance. The presentation regarding the possible TV-Anytime profile was very relevant since it represents a real case which study may be very useful.Following the discussions, it was decided that a preliminary approach for MPEG-7 profiling should be adopted, notably: MPEG-7 profiles will be defined across MPEG-7 parts, at least for MDS, Audio and Visual. The keyword to define profiles is 'functionality' - profiles are a set of tools providing a set of functionalities for a certain class of applications. A new profile should be defined if it provides a significantly different set of functionalities. The keyword to define levels is 'complexity' - levels limit the complexity associated to a certain profile@level. A new level should be defined if it is associated to a significantly different implementation complexity. Profiles should be named independently of applications to avoid sending wrong messages. Levels should be labelled using numbersThis approach is preliminary and will be further addressed in an AHG created to address interoperability and profiling issues. As a result of this session, the MPEG-7 Profiles under Consideration document (N4678) was updated, including now 4 profiles under study.
MPEG-7 Systems ExtensionsM8170 Claude Seyrat & Cedric Thienot, Proposal of requirements for MPEG-7 V2N4715, Call for Proposal on MPEG-7 Systems ExtensionsAt a joint session with the Systems group, MPEG-7 Systems extensions requirements were reviewed targeting the release of a Call for Proposals. The major requirements regard improved coding efficiency for MPEG-7 descriptions and coding efficiency for MPEG-21 DI Declarations. This means that additional binary coding tools will be standardized in addition to the currently available BIM tool. The answers to the Call for Proposals are requested for July 2002.MPEG-7 Applications and PromotionM8006 Neil Day, Report of the MPEG-7 Applications and Promotions to Industry AHG M7933 Jose Martinez, Proposal for MPEG-7 Overview updateN4674, MPEG-7 Overview (2 weeks editing)N4675, Introduction to MPEG-7

MPEG-21
MPEG-21 Requirements (General)M8218 Jan Bormans (editor), Report of the Ad-hoc Group on MPEG-21 Requirements N4681 Jan Bormans (editor), MPEG-21 Requirements v 1.0Version 1 of the MPEG-21 Requirements was formally published at the Jeju meeting. Until this point the MPEG-21 Technical Report, which provides a high level overview of the multimedia framework, has been the place where MPEG-21 requirements have been defined. The MPEG-21 Requirements document will be the place where all of MPEG-21’s requirements are documented and will be regularly maintained from this point forward. The document contains requirements of varying depth that reflect the contrasting intensity of activity in the different parts of MPEG-21. For example, the requirements gathered for the Rights Data Dictionary, Rights Expression Language and Digital Item Adaptation are very well defined and they have been used as the basis for issuing Calls for Proposals and evaluating the subsequent submissions. The requirements of other parts of MPEG-21 remain less developed, such as MPEG-21 IPMP, persistent association of identification and description with content, event reporting and content representation. It is expected that these will be further developed over the course of future MPEG meetings.
M7941 Liaison Statement from ITU-T SG 16 to SC 29/WG 11 on Mediacom 2004 (SC 29 N 4636)M8221 John Magill, Jan Bormans, Updated Description of the Relationship between the MPEG-21 and Mediacom 2004 ProjectsITU-T SG16 Mediacom 2004 is dealing with content security issues and they submitted a liaison statement expressing their interest in the development of the MPEG-21 standard. They have a specific interest in the RDD-REL work and would like to become more involved. The Requirements group therefore recommended that WG11 invite ITU-T SG16 experts to the next MPEG meeting to become involved in RDD-REL specification and to send them copies of the latest WD’s from the Jeju meeting. SG16 has also expressed an interest in IPMP but at this stage do not plan to develop any encryption architecture within the context of their work. Finally, SG16 reported its progress in the analysis of its multimedia framework. They have also identified 7 key elements in their analysis of a multimedia framework and have constructed a comparative table with the elements in the MPEG-21 TR to identify where they intersect, overlap or are separate.
MPEG-21 IPMP RequirementsThe lack of a comprehensive set of MPEG-21 IPMP requirements remain a concern as, despite their limited definition, there is an MPEG-21 IPMP specification at a Committee Draft status. However, the specification was not further developed during the Jeju meeting as IPMP experts devoted their attention to the MPEG-4 IPMP PDAM.MPEG-21 IPMP requirements appear in the context of other specifications such as the Rights Data Dictionary, Rights Expression Language and Digital Item Adaptation. In common with MPEG-7 IPMP requirements (for which a specification does not exist) there is a need to be able to manage and protect descriptions and apply rights expressions to descriptions. For example, in the context of
40
Digital Item Adaptation, an MPEG-21 IPMP system would ‘protect’ the association of permissions governing the context in which content may be adapted.An additional need is to define the requirements for Digital Items as opposed to the management and protection of Resources (‘content’) represented by existing MPEG coding standards. A resolution was approved by the WG11 Plenary to request that an activity to define the requirements for the management and protection of MPEG-21 Digital Items be initiated.
MPEG-21 RDD-REL RequirementsM7980 Chris Barlas, Ad-hoc Group on REL-RDD Requirements Report M7981 Chris Barlas, OeBF Liaison Statement on Rights Grammar RequirementsBased upon the recommendations submitted by the AHG on REL-RDD requirements, these requirements were modified to reflect the developing understanding of MDS experts who are currently developing the RDD & REL specifications. These were approved by the Requirements group and documented in the MPEG-21 Requirements v1.0 (N4681). The Open eBook Forum (OeBF) have also reviewed the MPEG-21 RDD-REL requirements and submitted some comments, recommendations and proposed a new requirement. These were taken into account and the new requirement was accepted. A liaison statement to OeBF was prepared and a resolution was agreed, thanking the OeBF for their contribution.
MPEG-21 Identification and Description RequirementsM7923 Niels Rump, Requirements on DII&D (resubmission from M7177)The scope of Part 3 of the MPEG-21 standard was further refined to address Digital Item Identification rather than its previously wider scope of Identification and Description. Consequently there are now a number of requirements within the scope of MPEG-21 that fall outside of Part 3 and may themselves be candidates for specification. One such example is the requirement to identify MPEG-21 ‘Users’, including value chain participants. In order to effectively control how Rights Expressions can be associated with Digital Items and Resources as they pass down the value chain it will be necessary to identify value chain participants. While there have been a number of initiatives to develop proprietary identification systems for Users within specific communities, no international effort has as yet been initiated to address the requirement for the identification of value chain participants. It is appropriate to consider whether, within the scope of its specifications to support an integrated multimedia framework, this is an activity in which MPEG should take a lead.
MPEG-21 Use Case ScenariosM8163 David Parrott, Reuters Use Cases for RDD/RELIt was agreed during the Jeju meeting to revise the MPEG-21 use case scenario document that was last reviewed at the Sydney meeting in July 2001. New use cases were contributed that illustrate the application of rights data dictionary and rights expression language tools and these need to be integrated. In addition, it is likely that further use cases will be submitted in response to the Call for Proposals for Digital Item Adaptation at the next meeting. The use cases are important as they form the basis for defining ‘Core Experiments’ to validate specifications.
MPEG-21 ArchitectureM7911 Niels Rump, MPEG-21 Technical Architecture AhG ReportM7910 Niels Rump, MPEG-21 Technical Architecture Working Draft M7962 SM Shen et al, Updating MPEG-21 IPMP based on MPEG-21 System Architecture M7963 SM Shen et al, Rights Holder in MPEG-21 IPMP and its Mapping to MPEG-2/4 IPMP M8032 Ian Burnett, Report on AHG on developing MPEG-21 Software and Systems Model (YM) M7990 David Singer, Towards an MPEG-21 File FormatN4686 Ian Burnett et al, Draft Requirements for Digital Item Processing for ApplicationsThe start point for the discussion about MPEG-21 Technical Architecture began with the analysis produced at the Tokyo AHG meeting in February which contained a diagrammatic representation of the architecture. The diagram (see figure 1 below) was discussed and further modified by the
41
Requirements group during the Jeju meeting and discussed at a joint meeting between Systems, MDS and Requirements. Considerable difference of opinion between MPEG experts emerged about the nature of the MPEG-21 architecture. It was also not clear between experts what are the differences between the architecture of MPEG-21 and the architecture for other MPEG standards and how they relate to each other. There was also considerable difference of opinion about the usefulness of the diagram. Generally it was felt that it only represented the high-level architecture described in the Technical Report (i.e. the architectural elements) rather than the integration of the specifications under development (e.g. RDD, REL, IPMP, DIA, etc).It was decided that the diagram (see below) was probably not the most helpful start point for this analysis and would not result in a satisfactory set of requirements for the development of MPEG-21
systems.
A different start point for the analysis was therefore adopted. It was decided instead to examine the processes that result when a Digital Item Declaration is received by an MPEG-21 “processing engine” (this could be a terminal, software client, etc). A working document was produced (N4686 – Draft Requirements for Digital Item Processing for Applications) which provides a record of the discussions held in Jeju including a list of the processes that a systems application needs to perform upon receiving a Digital Item Declaration. The intention is to develop the discussion over the coming meeting(s) by considering several DID application scenarios. The working document will continue to be developed at the Fairfax meeting to express a full set of requirements for DI processing in a variety of application scenarios. It is expected that the resulting requirements will form the basis for developing the MPEG-21 sYstems Model (YM) and possibly an MPEG-21 File Format, and some interesting contributions were discussed that were helpful in developing the thinking of the Requirements group for the development of these tools.

The Final Call included some minor changes to the logistical arrangements for evaluating the responses, and also included two accompanying documents: N4684 contains a set of requirements against which the responses will be evaluated; and N4685 defines the evaluation criteria that will be used. An AHG group has been formed that will meet on the 4th and 5th May prior to the next MPEG meeting in Fairfax to conduct the evaluation. The Resolutions from the Jeju meeting noted that the Requirements group recommend Anthony Vetro to lead the evaluation of the DIA Call for Proposals. SC29 was also formally requested to approve the creation of ISO/IEC 21000 Part 7, Digital Item Adaptation.
Persistent Association of Identification and Description with Digital ItemsM7899 Hideki Sakamoto, Case Study of Persistent Association of Information with Digital Items: cIDf & #8217’s Trial on ID ResolutionN4682 Keith Hill, Call for Requirements for the Persistent Association of Identification and Description with Digital ItemsA Call for Requirements was published (N4682), inviting the submission of requirements for the persistent association of identification and description with Digital Items – the fundamental unit of trade within the MPEG-21 Multimedia Framework. While MPEG has identified the need for such persistent association of identification and description, this Call will enable the requirements to become better understood in order to decide what MPEG might consider necessary to standardize. The timetable for the Call for Requirements requests that responses be received by 14th July 23:59 GMT so that they can be discussed and evaluated during an ‘ad-hoc’ group meeting prior to the MPEG meeting to be held in Klagenfurt.

3D Video CodingN4679, Preliminary Requirements for 3D Video support in MPEGThe 3D Video Coding break out group met with the Requirements and Video groups twice during the week. In the first session, the contributions above listed were presented and discussed. From this discussion, it resulted that the objectives of 3D Video coding seem to be different for different experts and thus an effort to more precisely define the problem under study was needed. To reach this objective, the break out group was asked to draft a document including the following sections: Problem definition using a model or architecture Objectives highlighting what needs standardization
43
Relation with available standards (and on going activities), notably with MPEG standards (what is available and what is missing ? what are the limitations of the current standards ?) Applications and products available List of requirements (drafted using MPEG template) clustered in a meaningful way In the second session, the document resulted from the work of the break out group was presented. This document allowed to conclude that: There are different approaches to the 3D Video problem. This approaches seem to fit together but this conclusion has still to be checked notably at the light of requirements such as backward compatibility with MPEG-2 Video. There are many relevant tools already available in the MPEG-2, MPEG-4 and MPEG-7 standards. Further study is needed to identify which tools are missing in terms of available standards. There are many applications which require 3D Video technology and also many products already available in the market. The requirements must be clustered in terms of Audio, Visual and Systems since 3D Video applications require not only specific video coding technology but also audio and systems tools, e.g. for powerful interactivity. A joint AHG with the Video group was created to improve the draft document created during the meeting (N4679), notably in terms of the definition of the problem, relation with available standards and listing of requirements independently of any application domains.
Digital CinemaN4680, Digital Cinema RequirementsThe Digital Cinema break out group met with the Requirements group three times during the week. These meetings addressed the following topics: Discussion on the way to proceed with the digital cinema activities within MPEG Update of the MPEG digital cinema requirements to incorporate the answers provided by various bodies as feedback to the letters sent at last MPEG meeting asking for requirements Preparation of a new Call for Proposals and the logistics for the corresponding tests.The conclusions regarding these topics were: Due to several factors, it was decided that MPEG will issue a new Call for Proposals addressing the Video Distribution requirements in the Digital Cinema Requirements document New tests have to be prepared adopting new testing methodologies, and better material. Moreover the logistics has to be carefully prepared to avoid the problems happened in the first round of tests. The group discussed all the logistics factors that have to be considered in order to guarantee successful tests. An updated version of the Digital cinema requirements document was produced (N4680) already incorporating the feedback from three bodies. This revised document was presented to the Video group.A joint AHG with the Test group was created to address all the issues related to digital cinema within MPEG, notably improvement and update of the requirements and preparation of the new tests.

This was already discussed when the OCI related to rate control were specified. It was decided that the specification of rating should be application dependent and that MPEG should just provide a place holder for that. No new reasons were brought to change this previous understanding. In addition, new “OCI” should be standardized in MPEG-7 rather than OCI.M8016 : Document not available.

What is correction and extension is not clear. The proponents should come with a new profile definition.M8124 : This document provides analysis of the complexity of Flextime nodes, quantization and media control nodes. It serves as the basis for the discussion on the merge of Advanced 2D and Advanced Main 2D as well as on the inclusion of Quantization in Main 2D, as recorded below.
Decision on the evolution of Amd.2 profiles1. Advanced2D:
Add the Flextime nodes (Temporal Group and Temporal Transform) to Advanced 2D;2. Main2D
Add the Quantization node and Inline to Main 2D; Remove WorldInfo and Group (WorldInfo and Group are not in Core2D).
Decision on the evolution of Amd.2 levelsSpeed adjustments in MediaControl and Temporal Transform
1. Main2D
49
Level 1 : no speed adjustments. (speed parameter in MediaControl and in TemporalTransform shall be 1; scalability field in TemporalTransform shall be [1,1])
Level 2 : speed adjustments supported but audio resampling is not required (i.e no restrictions on the field values conveyed in BIFS stream, but rendering constraints for audio in place).
Level 3 : remove restrictions from MediaControl and TemporalTransform (neither bitstream nor rendering constraints). Also remove the restrictions from Sound2D (allow location and spatialize); and remove the restriction from AudioSource for rewind and fast forward [of course this does not apply to broadcast]
2. Advanced2D: Level 1 and Level 2 : the same as Level 2 in Main2D Level 3 : the same as Level 3 in Main2D
Inline Support1. Main2D
Level 1 : Ignored. Level 2 : Restricted to supporting Simple2D+Text. No more than 4 Inline nodes in
the scene at any one time. Restricted to supporting content to that created with Simple or Basic Profile Scene Graph, and Simple2D Graphics ( Simple2D+Text).
Level 3 : No restriction (of course Inline content cannot exceed the profile of the main scene).
2. Advanced2D: no restriction.
Quantization in Main2D Level 1: ignored. Level 2 and Level 3: isLocal, useEfficientCoding not supported (as in Core2D Level1 and Level2).14496-1 3rd EditionTopics

Coding of nodes : The SNHC specification uses specific coding for node for improved efficiency. Implication on the current Systems architecture and possibly better solutions need to be investigated (ref. AHG)Animation : The current BIFS Anim may be extended to solve the pb. This will be investigated in the BIFS AHG (ref. AHG).
Elementary Stream ManagementM8145 : Media Node URLs. How to specify semantic of URLs in OD so that one can e.g. select in a media dependent node a specific stream from an MP4 file. The URL semantic has to be dependent from the media node context (e.g. same URL used for the audio node and video node, while the selected streams are respectively a audio and video streams). To be discussed further and completed for an amendment of the MPEG-4 Systems specification.

Discussed and result documented in a preliminary Call for Proposal. The Call for Proposal will be issued in Fairfax. See CfP output document for further information on the timeline.
Elementary Stream ManagementM8172. Answer to the Call for Contribution issued at the Pattaya meeting on incremental construction of the scene. In the case of big media access unit, the receiver may have problem to have long time to get the complete set of information which are carouselled. If the scence can be
52
separated into several parts and some parts can be shared by the different users the problem could be solved. To support this solution, following extension of SL are proposed
Pointer to the first SLP in the SLConfigDescriptor; Pointer to the next SLP in the SLPH; The last SLPH shall point to the non-existing SLP.
This contribution also claiming that there are some problems in scalable streaming and IPMP key synchronization and they can be solved by this contribution. But the BIFS carouselling problem could be more completely solved by the transport laye, such as MPEG-2 DSM-CC data carouselling or application standards such as DVB or ATSC, even though such scenario needs more careful analysis. Incremental contstruction of BIFS may not be the only existing problem of BIFS carouselling we have. And the solution seems not to be complete. But there are no other clear solutions to solve the problems stated in the Call for Contribution at the moment. Therefore, this will go to WD for the further consideration.
M8009, M8010: Discontinuity handling in the case of bistream switching. This contains the requirements, analysis of the current OD framework, and the proposed solution for the case of switching the bitstreams during the presentation. The proposed solution is having a discontinuity descriptor with a flag to signal the existence of the discontinuity. This problem seems to be solved by applying appropriate constraints to bistream generation process to allow seamless bistream switching. In addition MPEG-4 SL has no requirements to support bitstream switching. This activity will be therefore discontinued.

M8046 : Introduction of changes requested by IETF.
IETF feels generic payload format is quite complex and has doubt about the quality of the drafts. IETF feels it may have unidentified problems.
* It is written in MPEG-4 system centric point of view. It could be possible to rewrite it in the elementary stream point of view without mentioning MPEG-4 SL.* One of the reasons IETF people doubts is they didn’t see much comments on their reflector.
IETF needs implementation for the verification* FT has implemented the generic draft but not demonstrated it at the IETF meeting yet.
54
It could be better to finalize simple draft first independently on the generic draft. Its implementations are already demonstrated by ISMA.Simple draft can be de-correlated from the generic payload format without any technical changes. It may help to move forward quickly.
* Simple draft can carry various MPEG-4 streams including OD stream and BIFS stream.* SL Packet Header can be carried by simple draft but they are invisible to RTP. Application understanding SL could get the reconstructed SL Packet Header.* The generic payload format could then be considered as an extension of simple draft.
How to proceedHave a simple draft de-correlated from generic payload format.Send a liaison to IETF
* To move forward with simple draft at the moment.* To hold the generic draft to be clean-up and accommodate the requirement from JVT.
Work further on the generic draft including the requirements from JVT.
Joint meeting with Visual and RequirementsRequirements for JVT Carriage (Ref. Requirement document).
Carriage of JVT Content
M8125 : MPEG-2 NAL This contribution is proposing the complete NAL syntax for JVT over MPEG-2. This would be nice as a starting point. But there is a strong concern about having multiple NALs specific to each protocols. It is more desirable to design the general NAL rather than having protocol specific NALs. This concern shall be addressed as a part of resolution.
M8053, M8055, M8056 : MP4 for JVT to address the entities smaller than AU. According to the definition of AU of MPEG-4 Visual, JVT needs AU fragment level addressing. This contribution proposes “sub-sample” to contain AU fragment, Data Partitions, or supplemental enhancement Information. But we are not very clear about the exact requirements of JVT. Therefore we can not make any decision before having a detailed discussion with JVT.
M8057 This contribution proposes an extension of MP4 to support Picture level information. Dispositions on this contribution are same to M8056.
M8058 This contribution proposes an extension of MP4 to support bitstream switching. Dispositions on this contribution are same to M8056.

ArchitectureJoint meeting with Requirements and MDS
M7910 : The working draft was revised. Difference between MPEG-21 architecture and YM (reference model) was discussed : sYstems Model : This is the MPEG-21 reference software (it comprises software modules implementing MPEG-21
tools and exercising MPEG-21 functionnality); MPEG-21 Architecture : This is a functional description of a generic MPEG-21 terminal (functional blocks with
identified normative interface as well as information flow).
A couple of issues were raised and discussed : Transport of the Digital Item (RTP, MPEG-2, …) : This is out of the scope of MPEG-21 but need to be done
specified in appropriate place (e.g. in MPEG-4 for MP4, in MPEG-2 for MPEG-2 systems, …); Parsing only diagram : The current architecture only includes parsing. Likely more is done. The box will be
identify as “tools” rather than “parser”. We don’t need a message bus : The architecture should only mentioned normative tools, the flow of information
between them and the conformant interface. It should not contain implementation details (.g. like the message bus). It will be removed.
Binarisation of the digital item MPEG will develop a binary version of the DID. We will allow both textual and binary format like in MPEG-7. We have the appropriate tools in-house for binarisation with MPEG-7 Systems. Textual/binary does no have any impact on the MPEG-21 processing engine architecture. MPEG-21 has specific requirements for its binarisation. The BiM shall compress the DID efficiently; The BiM shall support multiple XML namespace; The BiM shall allow to reconstruct an XML DID canonically equivalent to the original MPEG-21 DID. The BiM shall allow the compression of XML data for which the schema is not known at the MPEG-21 processing
engine.They will be included in the current CfP for MPEG-7 extensions.
File Format for the digital itemM7990 : Proposal of an MPEG-21 file format. Since the proponent was not present, the contribution was little review. Still, it was decided that MPEG will develop a file format for the digital item. We have the appropriate tools in-house with the MP4 file format. The following MPEG-21 specific requirements for file format have been identified : The MP21 file format shall allow the bundling of the DID(s) descriptors and its resources in a single file. The MP21 file format shall allow random access to descriptors and resources. The MP21 file format shall be backward compatible with the MP4 file format.
56
The MP21 file format shall be able to refer to or/and include a broad set of resource formats (including HTML).The Systems group will make a call for contribution for the next meeting and the MP21 file format will be developed as an amendment to MP4.
Persistent associationSee requirements report.
Presentation of the digital itemThe current MPEG-7 Systems CfP calls for presentation tools for MPEG-7 data. Such tools should allow the visualization of MPEG-7 metadata (e.g. for an EPG) in a visualization format (e.g. HTML or XMT). Such tools would need to access both metadata and resources, possibly bundled in an MPEG-21 digital item. Similar concepts were discussed within MPEG-21. Therefore iIt was decided to remove this item from the MPEG-7 Call, to better understand the common technology that needs to be develop for MPEG-7 and MPEG-21. Contribution on the topic are welcomed by next meeting.

The MPEG MDS sub-group activities included work items for MPEG-7 and MPEG-21 standards. The primary MPEG-7 work items included MPEG-7 Multimedia Description Schemes v.1 (FDIS) and MPEG-7 MDS Extensions (WD). MDS also worked with other groups on MPEG-7 Conformance (CD) and MPEG-7 Extraction & Use (PDTR). The MPEG-21 work items included MPEG-21 Digital Item Declaration (FCD), Digital Item Identification & Description (CD), Rights Expression Language (WD), and Rights Data Dictionary (RDD).

N/A AHG on Editing the MPEG-21 DID FCD Study and DII&D CD Study, Niels RumpResults: Both documents were under balloting following Pattaya meeting and were not revised.
Furthermore, “study” documents were not produced given lack of new input.
7944 AHG on Editing the MPEG-21 RDD WD, Chris Barlas and Godfrey Rush for the AHGResults: Held AHG meeting to discuss OeBF and relationship to RDD/REL. Revised Model for Structure of Rights Data Dictionary and concept definitions Enhanced description of scope and terms & definitions.
8063 AHG on Editing the MPEG-21 REL WD, Barney Wragg for the AHGResults: Held joint AHG meeting with RDD AHG Sunday prior to Jeju Island meeting. Period
after Pattaya meeting focused primarily on developing REL use cases, mapping to
69
requirements, and designing core experiments. Work of AHG did not produce directly any modifications to existing REL WD 1.0 prior to Jeju Island meeting.
8062 AHG on MPEG-21 Core Experiments, Barney Wragg for the AHGResults: Held AHG meeting with OeBF to discuss alignment of requirements. Held joint AHG
meeting with REL AHG Sunday prior to Jeju Island meeting. Recommendations: Adopt example use cases into annex of WD Define extension to draft MPEG-21 core REL Align terms with RDD Define relationship with DID Recommend a joint meeting with MDS and Requirements to review N4336 Further core experiments Increase coverage of evaluation Evaluation of relationship with DID
8032 AHG on developing MPEG-21 Software and SYstems Model (YM) Ian Burnett for the AHGResults: As reported during MPEG plenary. Limited discussions on the reflector since Pattaya.
The majority of postings were cross posts from the IPMP reflector and MPEG-21 Architecture reflector. The YM discussions were effectively placed on hold while the MPEG-21 Architecture reaches consensus.
Review of MDS Core Experiments results
Num. Contributions8062 CE on the MPEG-21 REL
8062 CE on the MPEG-21 RELBarney Wragg on behalf on CE.Results: The REL Core Experiments resulted in document providing XrML examples. The core
experiment was derived from a usage case provided by M. Paramasivam (Microsoft) at the 58th meeting in Pattaya. This case was originally developed to evaluate requirement 2.1.8, as defined in N4336. The case was expanded to cover several requirements.

Num. Contributions7946 MDS Video Editing Segment Description Tools: Addressing XML Schema Compliance8209 Supporting Summarization in the Variation Set DS
7946 MDS Video Editing Segment Description Tools: Addressing XML Schema ComplianceEric Rehm (for J. Utz, III)Issues:
Identifies esoteric XML Schema problem with current schema specification for MDSConsequences:
MDS V1.0 is not a valid XML Schema because of alternating elements in analytic video editing content model (XSQ XML Schema parser fails on MDS schema)
XSV shows other errors in audio and video which need to be flagged for attention of audio and video
Possible solutions: Do nothing Yoshi #1: Change DDL (DDL revision requires amendment) Yoshi #2: Issue “call for solution” Yoshi #3: Wait for XML Schema update to solve problem Yoshi #4: Reconsider syntax definitions of relevant tools. Eric #1: Redefine syntax and put semantic constraint – requires extension for
validating parsers. Modify version 1.0 and rely on inspection scripts for validation. Add normative annotation/appinfo elements that define required lookahead.
Results: Adopt Yoshi #4. Contact and confirm with Video Editing proponents and Y.
Shibata. Create new XML content model for MDS v1.0. Incorporate the revised syntax as provided by E. Rehm during ISO editing period.
8209 Supporting Summarization in the Variation Set DSE. RehmResults:
Identifies use for Variation DS to include links to summaries and views Proposes to add two elements to Variation DS To be revisited for MDS v.2 in discussion on Thursday. Group will decide on
incorporating into XM or WD. The more general question of how to extend MPEG-7 schema will be studied in MDS AHG.

Niels RumpIssues:
Reviewed the NB comments on DII&D CD with MDS group. Niels applied the changes to the current CD document and prepared the draft of the FCD based on decisions of group. Niels also prepared the draft of the DII&D CD DoC document.
Some discussion was had in regards to description aspects of DII&D. Group has supported the position to rename the DII&D to DII since the description aspects of the DII&D are covered completely by DID.
Some discussion was had on the requirements for DII&D to identify other entities in the MPEG-21 framework. The group has discussed allowing the DII&D part of the standard to only address identification of digital items and not other entities, with the possibility that another part of the standard will address identification of other entities in MPEG-21.
Other editorial comments are to be handled by Niels. Reviewed a draft for RFC for registration authority for identification systems.
Output:
72
FCD DoC RFC for Registration Authority for Identification Systems Resolution from MDS for Registration Authority Resolution for change of name of Part 3.
MPEG-21 RDD-REL Requirements

BoG on RDD/REL B. Wragg
Report of AHG on RDD/REL C. BarlasResults: Chris Barlas gave a report of meeting with OeBF (Open e-Book Forum). M7981 – Liaison statement lists its requirements (about 15) and issues comments to MPEG. One OeBF requirement (3.6.5) does not seem to have mapping to particular MPEG-21
requirement. The requirement deals with the ability to differentially express rights expressions for different individual users and groups. It is not clear that this item needs MPEG to develop specific requirement, since it is fairly basic and already presumed to be accommodated by MPEG-21 requirements. One possibility is to develop use case that demonstrates this.
What is the process for responding to OeBF?o Chris Barlas and Keith Hill will work Jans Borman to prepare a response to the
OeBF liaison statemento Make resolution at plenary to thank OeBF for comments
8163 Report of AHG on RDD/REL D. Parrot
Proposal gives new use cases for RDD-REL for different applications:o Web distributiono Video news distribution (media company to distributor)o E-commerce and channel partner distributiono Real-time financial data distributiono Picture archive access
Discussion: where should the use cases be explored – MDS or Requirements? Action:
o Work with RDD-REL BoGo Propose CE to develop rights expressions for use cases
BoG on RDD/REL B. Wragg
The RDD/REL BoG has identified a number of MPEG-21 requirements on RDD/REL which are possibly incorrectly stated or not appropriate for RDD/REL, including
o Modification of Expressionso Authentication of Expressions
73
o DIA Requirements (2.1.7) recommend Requirement is clarified, expanded and brought into context of MPEG-21
frameworko 2.1.16 Expression Language support of dictionary terms

Presentation/Browsing of Digital Items
Introductory discussion on Technical Architecture and Software There needs to be clear distinction between technical/terminal architecture and reference
software implementation Role of YM has been clarified to be software for reference implementation
MPEG-21 Technical Architecture N. Rump
Further develop & document the requirements for Technical Architecture Draft of MPEG-21 Technical Architecture diagram was developed in Tokyo ad-hoc
meeting. The diagram has been further revised to allow plug-in of tools through plug-in interface.
o Concerns were raised about the sequential processing nature of the architecture and whether the sync and messaging protocols were worked out
o At some point need to define transport of digital itemso Should revise the message bus to reflect flow of information rather than passing of
messageso Renaming current technical architecture diagram to MPEG-21 “Processing Engine”
to reflect the nature of the diagramo Activity on technical architecture to remain in Requirements for moment

MPEG-21 Binarization of DID
Do we need capabilities for binarizing MPEG-21 DID? Seems “yes”. Need to draft requirements.
Requirements:o The MPEG-21 binarization shall
compress the DID support multiple namespaces allow reconstruction of canonically equivalent XML to the original
MPEG-21 File Format D. Singer (not present)
Action: issue call at this meeting in the MPEG-7 Systems call MP21 file format shall allow:
o Bundling of DID descriptors and its resources into a single fileo Random access to descriptors and resourceso Be backwards compatible with the MP4 file format
Persistent Association
Draft call for requirement in Jeju. Refresh in May. Final call in July.
Presentation of the digital item
Need contribution or proposal on issues of presentation of digital items. Otherwise, it is difficult to proceed in developing mandates for AHG. Need also to develop “Processing Engine” before understanding relevance of “presentation”
Ian Burnett gave demo of browser for Digital Items that presents digital item by applying stylesheet to DID. Can produce HTML or SMIL.

7918 MPEG-7 Profiles and Levels ArchitectureMPEG-7 Interoperability Test-bedWo ChangProposal: MPEG-7 N3751 identifies large number of application domains. Furthermore, MPEG-7
defines 409 global types (how many combinations) Proposed objective of profiles/levels is to allow interoperability of systems
implementing same profile and to allow mix of multiple profiles. Introduced MDI, which is numbering scheme for MPEG-7 DSs and Ds. How to allow profiling?
75
(1) Replace MPEG-7 Root Element(2) Add attributes to MPEG-7 root element.(3) Use XML namespace and schemaLocation to locate subset of MPEG-7 schema
Propose Profile and Level registration and management sa central repository.Discussion: Concern was raised that the proposal does not consider the complexity dimension and
that something more is needed for defining profiles than creating a subset of the schema. For example, it is important to consider how the tools are used in making a description.
Action: Known criteria for profiles/levels include interoperability and complexity. There is still
lack of understanding how requirements for interoperability and complexity drive creation of profiles/levels in MPEG-7 (lack of proposals).
8038 MPEG-7 Profiles and Levels using XML NamespacesEric Rehm Proposal:
Motivation is that MPEG-7 could be costly to implement given the large number of tools and therefore it may be necessary to define profiles. This can be done using Namespaces – for example, by defining one namespace per profile (across parts – MDS, Visual, Audio).
Recommendation: Create a single profile namespace and schema for all types in a profile Augment Package/Scheme element with new restriction attribute
Comments: Questions were raised about whether namespace was necessary mechanism for
defining profiles. For example, it may be easier to include attributes in MPEG-7 root element.
8109 A User Description Profile for MPEG-7 and TV-AnytimeP. van Beek, M. I. Sezan Proposal:
Propose an MPEG-7 profiles for user preferences, which allows the subset of MPEG-7 tools that are used by TVA to be selected from MPEG-7 schema.
How to group and subset description tools:o By complexity – levelso By application – multiple applicationso By functionality – key driver for profileso No profiles
Conclusions: We will not necessarily split MDS, Audio, and Visual to form the profiles, but will
form clusters of tools from across the parts. The Requirements group will create resolutions from this meeting clarifying current understanding on profiles and levels for MPEG-7.

John R. Smith reviewed the Study on 15938-7 Conformance in joint meeting with MDS, video, audio, and systems groups. The major revisions included the definition of conformance with respect to MPEG-7 systems decoding and DDL processing. The specification was also revised to harmonization the view on conformance across the different parts of schema: visual, audio, DDL, and MDS. John pointed out areas that needed further development. The revisions of the study were supported by NB comments.
Results: Got commitment from Systems/DDL experts to work on content during a short
editing period immediately following the meeting. The detailed review of the voting on ISO/IEC CD 15938-7 was completed following morning.

Annex 7Video Group Report

Activities in Video Coding
Review of JVT work
The Video subgroup reviewed the results of the JVT January meeting (M8150). Particular questions of JVT to their parent bodies, as far as MPEG is concerned, were answered in document N4673. Joint sessions were held with the requirements group concerning the aspect of Profile and Level definitions. In particular, it is recommended to keep the number of different conformance points as low as possible, which can first be achieved by minimal definition of the number of levels. Both profiles and levels should more clearly be defined based on decoder complexity considerations, and taking into account envisaged application domains. A session on issues of AVC codec complexity was held jointly with the ISG. It was recommended to investigate complexity of encoder and decoder based on the JM software implementation, selecting specific tools in the range of low (all options off), medium and high (all options on) complexity. For tools to be selected in the medium complexity range, a selection similar to that in document M8127, which would map to a similar application domain as the ASP of MPEG-4 part 2.
Fine Granularity Scalability Profile
The verification test concerning FGS has been performed before the Jeju meeting, and a draft test report has been brought into the meeting. The verification test consisted of test A (the so-called dynamic test, captures taken by running over a true network) and test B (static test, comparison versus simulcast). Due to systems limitations, one part of test A had been performed differently from the other parts (FGST tool was not used in that particular one). During the review of the draft report, it was concluded that the result was rather ambiguous due to this fact. Hence, it was recommended to the test executors to repeat this particular test in time before the 60th meeting, and make available a refined version of the test report based on these results as input document before the meeting.All software related to FGS profile is finalized, such that the FDAM1 of software extensions was issued at the 59th meeting. Concerning conformance related to FGS, responsibilities have been identified for all streams. A Study of FPDAM1 of conformance extensions has been produced, and NBs were kindly asked to take this study into regard when voting on FPDAM1.
Software and Conformance streams, maintenance of standards
The Video subgroup has arranged in Jeju that all software related to MPEG-4 Video (14496-2) is made publicly available on web site http://megaera.ee.nctu.edu.tw/mpeg/. This also includes software related to encoder optimization (MPEG-4 part 7). Further support is planned, which will most hopefully lead to publicly available realtime software implementations of MPEG-4 Video Simple Profile. The Video subgroup also has arranged in Jeju that all conformance streams related to MPEG-4 Video (14496-2) will be publicly available on ftp site ftp://ftp.tnt.uni-hannover.de/pub/MPEG/video/conformance in a reasonable period after the meeting.
88
An output document N4583 "MPEG-4 Visual Implementers Guide List of Problem Reports" was issued as a revised version of the previous document from Pattaya meeting.
Status of 14496-2:2001/PDAM3
It was decided not to progress to FPDAM3 in Jeju, as the situation of software and conformance work related to PDAM3 appeared rather unclear. Contributors were requested to clarify this situation until the next meeting.
Request for error resilience supplement to MPEG-4
A request was made to the Video subgroup on implementing error resilience at the enhancement layer of existing scalability coding tools (M7919). However, it was identified that this would require definition of a new tool, object type and profile. It was concluded that such a major effort could only be justified if sufficient continuous support was evident by contributing parties.
Explorations
Advanced FGS
On Advanced FGS, six input documents (M7991,M8023,M8128,M8140,M8204,M8214) were received and reviewed, but it was concluded not to take any action on these items before the verification test on FGS is finalized.
Interframe Wavelet Coding
In Pattaya, an AHG had been installed to explore Interframe Wavelet coding. From an applications point of view, it was identified that possible merits of such a technique would be flexible scalability of bitstreams and resolutions for seamless integration of servers, networks, terminals, acquisition and storage devices with different characteristics. An important argument is that scalable coding should not penalize coding efficiency if compared against single layer coders, which is a new paradigm having in mind the traditional way of comparing scalable coding versus simulcast. Several input contributions were reviewed (M7906,M7977,M8130,M8131,M8207). A preliminary conclusion is that fully scalable technology already exists which is competitive with conventional coders on the market today in terms of coding efficiency, but not yet competitive with coders under development. Possible directions of improvement of such coders would be higher accuracy of MC, inclusion of post processing and RD optimization in truncating scalable streams. It is still premature to draw a final conclusion, but worthwhile to continue this investigation.To achieve comparison on an equal basis, experimental conditions have been defined in an output document (N4584). Future contributors are asked to use these conditions to make different approaches comparable.
3D Video Coding
On this activity, a meeting was held jointly with the Requirements group. 3 input documents were reviewed (M7930, M8040,M8107). It was identified that this work contains aspects which are prospectively related to the work area of the Video subgroup, especially in the areas of multiview
89
compression, image-based rendering and view interpolation. Before any further action is taken, it should be clarified what the architecture of a complete system should be, then to identify which tools are existing in MPEG standards, which tools would have to be enhanced or newly defined.defined
Digital Cinema
The Digital Cinema work in its present status is still (or better said again) concerned with investigation of higher-level requirements. Video expertise would surely be needed later in the process.

Record of Audio plenary, joint meetings and task group activities
Audio plenary discussionsLossless coding: During audio plenary, a number of contributions related to the issue of a potential new work item on lossless audio coding were presented and discussed. After ongoing discussion on this topic over a number of recent AhG periods, it was understood that a decision had to be taken at the 59th MPEG meeting as to whether to adopt a new work item on lossless audio compression or to abandon the activity. Mr. Moriya presented the associated AhG report (7955). A number of contributions on the technical feasibility and potential applications of lossless audio coding were presented next, including 7956 (Lossless scalable audio coding based on MPEG-4 standard, Moriya), 7975 (Evaluation results of scalable lossless coding based on AAC, Nomura), 8024 (Evaluation Results of Scalable Lossless Audio Coding Based on MPEG-4 BSAC, Kim) and 8013 (Report on the audio lossless compression market investigation, Moriya). During the subsequent discussion it was agreed that sufficient evidence was given to indicate the technical feasibility and efficiency of a scalable system comprising a lossy coding core based on an MPEG-4 General Audio coder and an enhancement layer which will enhance the signal towards lossless reconstruction. In addition, it was felt that such a scalable approach would feature sufficient distinction over existing systems and would complement MPEG's existing general audio coding technology. It was further noted that the requirements from Digital Cinema call for lossless audio coding for archiving, and lossless or perceptually lossless coding for distribution purposes. Consequently, a new work item on lossless audio coding was adopted after a joint meeting with the requirements subgroup and positive assessment from their side (see section on joint meetings). An AhG will be started after the meeting to work on requirements for this work item until the next meeting. In the best case, a Call for Proposals could be drafted at the upcoming 60th meeting. A number of companies announced their support for the technical development process (NTT, NEC, Samsung, FhG, University of Wollongong, University of Nanyang), product deployment (NEC, Dolby, Samsung) or services (NTT) in case a work item on MPEG lossless Audio Coding was installed.
Audio software & conformance status document: In order to also provide non-audio MPEG members with a better understanding of the current status of the audio reference software / conformance data, the audio subgroup will produce a summary document as a container for this type of information (see output document N4601). This may evolve into a 'living' document for purposes of internal documentation.
Names of MPEG-4 Audio Extensions: Official names were decided for the two extensions to MPEG-4 audio currently under development:
95
1. "Backward Compatible Bandwidth Extension for General Audio Coding" (ISO/IEC 14496-3:2001 Amendment 1), MPEG-4 Audio Extension 1
2. "Parametric Coding of High Quality Audio" (ISO/IEC 14496-3:2001 Amendment 2), MPEG-4 Audio Extension 2
Joint MeetingsJoint meeting with ISG on MPEG-7 XM Integration
In a joint meeting with ISG the status of integration of the MPEG-7 Audio tools in the MPEG-7 XM was examined. A number of issues still need to be addressed, including outstanding tool documentations and the extraction tools. It was pointed out that further work on the extraction tools is required such as to:
Provide some documentation of each tool using the dummytype template file Make usage of each extractor self-documenting (e.g. batch file or MATLAB wrapper
'startextract.m/.bat') Enable integration of extraction tools and XM application (extractor should output XML,
also required for conformance testing)A workplan document will define next steps to be performed to advance the integration.
Joint meeting with Video, MDS and Requirements on MPEG-7 Profiles
Acknowledging the need for a better understanding of the notion of ‘profiles’ in MPEG-7, two contributions related to profiling (M7918, M8038) were presented and inspired extensive discussion. Two key questions evolved:
How to chose the profile (i.e. subsets of MPEG-7) ? How to express / address the subset of elements in an XML-based environment (the
“mechanics”)?Clearly, MPEG-7 may differ from previous MPEG technologies (which related to coding) in “what one has to be able to rely on” – a certain set of descriptions to be present in a description or applications being able to use certain descriptive elements or … ?In the past (MPEG coding), it was mandatory for the decoder to fully support a specified set of tools, while the encoder did not need to support such a full support. In MPEG-7 a “decoder” in an application does not necessarily need to exploit all elements present in a description. One possibility might be to specify profiles based on fixed sets of elements being present in the MPEG-7 description data in order to achieve interoperability.Some basic agreements were reached, e.g.
Profiles will be defined across part boundaries (Audio/Video/MDS) A profile relates to a set of functionalities related to a certain area of applications Levels will address the issue of complexity (what does “complexity” mean in this context –
extraction and/or matching complexity? In both cases this not only depends on the tools used but also on their usage)
A summary of the achieved consensus will be given in the resolutions of the requirements subgroup. Further work on this issue will happen within a requirements AhG.
Joint meeting with Video and MDS on MPEG-7 Conformance
The NB comments on the MPEG-7 conformance FCD were reviewed and responses were drafted. Further editing of the audio part of the conformance document took place in the corresponding audio task group (see below).
Joint meeting with Requirements on MPEG-4 Profiles and Lossless Coding
An answer to the M4IF liaison input (doc. 7881) on MPEG-4 profiles was drafted. With respect to a decision on a further work item on lossless audio coding, the corresponding contributions were
96
briefly summarized and the previous discussion within the audio subgroup was reviewed (see section on plenary discussion). Based on these inputs the requirements subgroup supported the recommendation for installing lossless audio coding as a further work item.
Joint meeting with MDS on description of multi-channel audio signals
It was acknowledged that the handling of stereo and multi-channel audio signals may not be sufficient within MPEG-7. Although there are currently MDS mechanisms which allude to the notion of audio channels, this construct cannot be used to allow description of common constellations, such as description of a mono signal downmix or descriptors describing inter-channel properties (cross-correlation). A proposed AttributeGrp addressing these concerns was included in the MDS Experience Model XM output document. The issue will be pursued further within the AhG on MPEG-7 Version 2 to be installed after the meeting.
Joint meeting with ISG on Bandwidth Extension tool complexity
The evaluation of computational complexity for the RM0 Bandwidth Extension (BWE) tool which had been conducted previously (see task group activities) was reviewed in a joint meeting with the Implementation Studies Group. It was agreed that further analysis will be carried out on the basis of the algorithmic structure of the tool.
Task group discussionsMPEG-4 Extension 1 Core Experiments (B. Edler)
The task group reviewed the technical description of the RM0 BWE tool (N7943) and edited the Working Draft on Backward Compatible Bandwidth Extension for General Audio Coding (ISO/IEC 14496-3:2001 Amendment 1).The workplan for MPEG-4 Audio Extension 1 Core Experiments was updated.The relevant contributions were reviewed:1. The AhG report (N8132)2. 2 NB comments on issues of low delay and reduced complexity BWE (N7966, N7976)3. Indication of potential core experiments on low delay and reduced complexity BWE (N7967)
The complexity of the RM0 BWE tool was discussed intensively. Coding Technologies provided complexity figures of a 24 bit real time implementation, which were appended to the workplan document for further reference. After a discussion about specifying acceptance criteria for reduced complexity BWE tools, it was decided, not to include fixed rules for a final acceptance in the workplan. Potential CEs on reduced complexity BWE have to provide evidence for possible acceptance.Regarding potential variants, the group agreed, that combinations of low delay BWE with AAC types other than AAC-LD would not be useful. Therefore acceptance criteria for the performance of AAC-LD/BWE combinations in comparison to AAC-LD had to be set up. The group agreed that the initial performance targets for the BWE work item apply, that is the coder/BWE system must perform at least as good as the coder without BWE at a 25% higher bitrate. Due to the difference in efficiency between AAC and AAC-LD, this translates into a comparison between AAC-LD/BWE at 32 kbps/ch and AAC-LD at 40 kbps/ch.Work will be continued in an ad-hoc group on Extension 1/2 Core Experiments
MPEG-2 AAC, Ref Sw and Conformance (R. Sperschneider)
A study on the DCor 1for MPEG-2 Part-7 (AAC) was prepared. Draft Corrigenda for MPEG-2 Part-4 (AMD 1 & AMD 3, AAC Conformance) and MPEG-2 Part-5 (AMD 1, AAC Software) were prepared and will be delivered to the SC29 secretariat at the end of the editing period. All AAC conformance test sequences are now available.
MPEG-4 Audio Text, Ref Sw and Conformance (M. Väänänen, B. Edler, R. Sperschneider)
97
A study on the DCor 1for MPEG-4 Part-3 was prepared. Draft Corrigenda for MPEG-4 Part-4 (Audio V1 and V2 Conformance) were prepared and will be delivered to the SC29 secretariat at the end of the editing period. The status of the MPEG-4 conformance test sequences was updated. All AAC test sequences reused from the MPEG-2 Conformance are now available. The review of the reference software documentation (README_usage) was delegated to the appropriate AhG.
MPEG-7 Core Experiments and Conformance (J. Bitzer, J. Herre)
The task group reviewed following input documents:1) Report of AhG (M8036)2) CE Cross Check (M7957)
Result: The proposed descriptor for AudioSignalQuality is useful and presents a significant enhancement of the WD document.
3) Editing Notes on WD (M8031)Result: Enhancement of WD
4) Multichannel Attribute Group (M8034)Result: It was acknowledged that the handling of stereo and multi-channel audio signals is not clear within MPEG-7. A joint meeting with the MDS subgroup was scheduled for further discussion.
The Audio part of the MPEG-7 conformance CD was revised according to the NB ballot comments received and the ‘Status and Workplan’ document for MPEG-7 Audio conformance was updated by adding/defining a number of tasks, responsibilities and milestones.The ‘status and workplan’ document for XM integration was updated and the software on the MERL ftp-site was reviewed. Information on the availability of software and conformance bitstreams was gathered.
MPEG-2 Layer III Issues (K. Brandenburg)
The adhoc group report of the Adhoc Group on MPEG-2 Audio Reference Software identifies several small inconsistencies and missing definitions within MPEG-1 and MPEG-2 (13818-3) audio, especially errors in the reference software. The inconsistencies include one obvious typo (“right” instead of “left”, the correct word is clear from the same and other clauses) in 11172-3 clause 2.4.3.4.9.3. The task group recommends:
to continue the adhoc group as recommended in the adhoc group report (m7978.doc) to start work on a draft corrigendum of 13818-5 to emphasize that the errors and incompleteness in the specification (11172-3 and 13818-3)
do not affect audio quality in any way since in all practical cases the error condition would probably not be reached and, if otherwise, the resulting signal differences would be inaudible

Discussion
MPEG-4 Animation Framework eXtension (AFX)AFX Technical Review: During this meeting, most of the time has been spent to review the text of PDAM. Most of the technologies in the PDAM have been reviewed again for the clarity and conciseness. Thorough review on bit stream syntax and node definition turned out to be very effective on reshaping the PDAM text. The changes are all incorporated into the study document (N4627)Subdivision Surfaces: Complexity analysis has been made (M7960) and reported the complexity acceptable. More discussion on the bit stream syntax and node definition is conducted.Interpolator Compression:
Continuing core experiments: A2 Subdivision surfaces A8 Multi-texturing A9 View-dependent coding A10 Physics-based animation
Verification Model 6.0 and PDAM 1.0: VM Status:
i. VM 6.0 has been updated both technically and editorially (N4626). PDAM Status:
i. Solid modeling is newly included in the WD because it has been successfully finished in the CE.
ii. From this meeting, the text of WD will be the text of PDAM 1.0 with a few exceptions described below.
iii. Curve interpolator is to be removed, since NURBS interpolator has a generic format to support this functionality.
iv. SFVec4f, MFVec4f: In order to support new tools in solids, it was necessary to define these new nodes. Since this is relevant with the general structure of BIFS, a joint meeting with Systems has been a good practice to understand the issue jointly. And more analysis on the impact of the new nodes will continue till Jeju.
AFX S/W implementation: S/W implementation is continuing the progress. Further workplan can be found in N4628.

Annex 10Test group report
Source: Vittorio Baroncini, Chair
IntroductionDuring the 59th MPEG meeting, held in Jeju (Ko), the Test Subgroup produced the following documents:
Revision of Dynamic Test 3 in MPEG-4 Visual Fine Granularity Scalability Tools Verification Test Plan (N4581),
Furthermore the following AhG have been established: AhG on Dcinema, chaired by W. Husak; E. Edwards (doc N4590), AhG on Fine Granularity Scalability, chaired by J.-R. Ohm, W. Li, K. Kim (doc N4587).
Fine Granularity Scalability Verification testsDocument N4581 describes the prolonging of the, formerly agreed, schedule of the Fine Granularity Scalability verification test.In the previous FGS verification test plan (N4456), three different dynamic tests under variable network conditions were defined. Due to implementation reasons (i.e. the use of a real-time system for the tests), it had been decided that the dynamic tests category iii) (IP network simulator with best effort and error correction) should be performed in the FGS-only mode (without FGST) in contrast to dynamic tests i) (IP network with priority) and ii) (IP network with best effort).During the preparation of the FGS verification test report in the MPEG Jeju meeting, it was found that it was hard to compare these results, as apparently the reactions of the tests subjects were biased due to the lower temporal resolution. It was therefore decided to repeat the dynamic test related to “IP network simulator with best effort and error correction”, with the same FGST coder settings that had already been used in tests i) and ii). Finally it has been decided that, the report of the new tests, together with all the test results of the previous tests, will be presented at the 60th MPEG meeting and approved for publication at the meeting.
Activity on Digital CinemaThe Requirements, Video and Test groups undertook several activity on the Digital Cinema.As first it has been recognised that, according to the number of requirements received by some relevant organisations (e.g. SMPTE, NATO etc.), the existing requirements document on Dcinema need to be revised.The existence of new requirements lead to the decision to begin a new video and test joint activity (conducted by an informal drafting group) aiming at the definition of the rules for a “Call for Proposal” for contribution to the Digital Cinema profile.To better achieve results in this area, the AhG on digital cinema has been renewed (doc. N4590) chaired by W. Husak and E. Edwards, with the following mandates:1. Continue the collection of inputs related to requirements on Digital Cinema to improve the
Digital Cinema Requirements document2. Improve the “expert viewing” methodology for Digital Cinema applications, as described in
doc. N4458,3. Continue the collection of the material necessary to run further testing activities,4. Prepare an input document to the next meeting describing the Draft Test Plan of further testing
activities.
114
The above AhG will meet at Burbank (CA) on 2002-05-1-2, with some representative of the Hollywood studios, to improve the requirements and the definition of the forthcoming competition tests.

OverviewThe main work items of the Implementation Studies Subgroup in Jeju are:
1. MPEG-7 XM reference software development for video/audio descriptors and Descriptor Schemes and related activity for the MPEG-7 Part 6: Reference Software for Version 1 and Version 2.
2. The acknowledgement of the first submission of HDL module received for the MPEG-4 “Part 9 Reference hardware description”.
3. The review of the first complexity analysis of the AVC codec and the draft of a guideline document for further contributions to complexity analysis.
Input contributions w.r.t. the above items are summarized according to the following table:

Detailed Report
MPEG-7 XM reference software developmentThree joint meetings have been taken place during the week between the ISG team involved in the XM development and video, MDS and audio. Discussions have started with the Video group with the review of the current status of the integration of the XM. The main outcomes of the discussions can be summarized as follows:
Joint Meeting ISG-Video
The status of the integration of video Ds is excellent. All Ds are fully integrated, documented and verified. The only possible improvement on the quality of the software is to verify the compilation warnings so as to prevent possible interface violations. Commitments have been taken to proceed with that verification by next meeting.A work-plan for the integration of Ds for version 2 has been defined (N4573).
Joint meeting ISG-Audio
116
Audio group and ISG verified the status of the submission and the integration. All modules have been finally submitted. Some documentation modules are still missing and most of the modules need functional verification. Commitments have been taken to complete the missing tasks by next meeting.
Joint ISG-MDS
All modules are integrated, but some of them are not compiling correctly on both platforms. Commitments have been taken to solve the problems. Two new DSs will probably be included in version 2
Meeting outcomes about Reference Software development
In conclusion main achievements of the meeting concerning the Reference Software development are:
The update of Work schedules for the XM integration (video tools, audio tools and DS) including both Version 1 and Version 2.
Integration of Version 2 tools will start after the CVS repository will be transferred to the TUM.
Reference hardware description for MPEG-4
First module for MPEG-4 part 9 “Reference hardware description” has been submitted on the ftp site. It is a DCT/IDCT MPEG conformant module. There are commitments for the submission of other modules for the next meetings.
Complexity analysis of AVC codec
The first contribution on the complexity of the AVC codec has been reviewed. On the basis of this contribution ISG acknowledge that the complexity analysis of video codecs is a difficult and time-consuming task. Therefore contributions coming from different sources and using different methodologies must be based on the same experimental settings so as to validate other contributor results and help in a synergic way to build a complete picture of the codecs complexity under analysis. For these reasons a guideline document containing detailed recommendations (Guidelines and work-plan for the complexity analysis of the AVC reference software N4571) has been drafted and an apposite ad hoc group has been established to proceed with such analysis N4576.
