…and market growth limits
Although video services demand is growing (e.g. video in Skype traffic is > 50%),
the videoconferencing market is constrained by several factors:
lack of interoperability among networks and manufacturers
closed solution environments
Complexity in switching between networks and/or video equipment from
different manufacturers located in different countries
Costly single vendor solutions can target only high profile corporate
customers
Need to unite a fragmented and non-interoperable market
place by involving players from the ITC sector to create a
common set of standards based on openness and
interoperability

HDVC mission
Provide business and consumer customers with easy to use,interconnected, and interoperable high quality video conferencing services
globally.
Define minimum profiles of features from existing standards for the user
to network and network to network interfaces.
Validate the profiles through the demonstration of interoperable video
conferencing across multiple operators and utilizing equipment from multiple
vendors.
Encourage the participation of additional operators, service providers,network suppliers, and equipment manufacturers that are aligned with and
actively contributing towards the mission.

HDVC strenghts
End to End interoperability - UNI profiling ensures interoperabilty
between any networks and any device; NNI profiling ensures
multivendor/multicarrier interoperability
Identities - Operators can choose whether to reuse traditional
telephone number (e.g. TEL:+391721234512) or SIP-URI (e.g.
name@operatordomain). Reuse of E.164 simplifies user experience.
Same platform as Voice over IMS – HDVC reuses the samenetwork infrastructures Operators will launch for mobile and fixed
telephony (IMS). The main difference is the introduction of the MRF
(conference focus) to handle point-to-multipoint services.
Open interworking to other solutions - NNI profile can be used as
a global reference for interconnection between networks
implementing different videocomunication solutions.
Basic service concept - Point to Point, Ad-hoc conferencing, Meet-
me, Content Sharing in conference, supplementary service support
(Originating/Terminating Identification Presentation, …)

HDVC on LTE
The bandwidth requirement is of 2 Mbit/s for 720p and 4 Mbit/s for 1080p. Thebandwidth can be reduced adopting H.264 High Profile. This profile isn’t available on
portable device.
End-to-End QoS is needed for large deployment to guarantee the bandwidth on radio
interface.
A bidirectional-simmetrical bandwidth requirement. Latency: Apart from large bandwidth requirements, a small round trip time is
required for reduced delays between frames. Any delay beyond 150-300ms becomes
noticeable and distracting.
HDVC service specifically require LTE access to be delivered on mobile networks.

Remarks
HDVC identifies “only” a technical profile (on top of standards capability), necessary
for UNI & NNI interoperability.
Standards (3GPP, HDVC) are essential but not sufficient for service enablement. The
following operational aspects were intentionally left out of profiling activity, but will
need to be addressed:
QoS assurance (over fixed access and at interconnection)Commercial settlement between Operators
NAT/Firewall traversal
Scheduling & management facilities
Consistent dial plan
Device Certification

Conclusions
Today there are different Videoconference Systems but there are still many problems to define afully interoperable service like the GSM ones.
IMS can be considered as and enabler to develop a fully interoperable Videoconference service
between different Telcos.
Telecomitalia and other operator, network equipment providers and terminal provider have
worked in GSMA to define HDVC service profile to be integrated in IR.39.
This profile define also the IP interconnectivity based on IPX and NNI SIP interconnection
between Telcos based on TS. 29.165.
The idea of HDVC as Open Forum where different Telcos, Network Equipments Provider and
Terminal provider can participate to implement this approach.
