IntroductionMedia streaming is a multimedia that is sent over a network and played as it is being received by

end user (Amir, 2011). Users do not need to wait to download all the media before playback but

instead they can play it simultaneously while the media is delivered by the provider. Video-over-

IP applications have recently attracted a large number of users on the Internet. Traditional client-

server based video streaming solutions incur expensive bandwidth provision cost on the server

(Wu and Li, 2011). Therefore there is a need to constantly research into these platforms in order

to provide a cost effective and efficient means of sharing video. With the explosive growth of

video applications over the Internet, many approaches have been proposed to stream video

effectively over packet switched best-effort networks. A number of these use techniques from

source and channel coding, or implement transport protocols, or modify system architectures in

order to deal with delay, loss, and time-varying nature of the Internet (Nguyen, 2012).

Video streaming over best-effort, packet-switched networks is challenging due to a number of

factors such as high bit rates, delay, and loss sensitivity. As such, transport protocols such as

TCP are not suitable for streaming applications. Conventionally, multimedia streaming

applications in the Internet run over UDP instead of TCP due to the following reasons (Jinyao,

Wolfgang and Bernhard, 2010).

TCP uses the Additive increase multiplicative decrease (AIMD) algorithm for congestioncontrol. This algorithm leads to a varying throughput of real time video stream and hence

severely impacts the video quality.

TCP applies packet retransmission to guarantee the delivery of packets. But ultimately,such packets may arrive too late for playback and therefore be useless. . To this end,many solutions have been proposed from different perspectives. From source coding

perspective, layered and error-resilient video codecs have been proposed.

1.1. Media StreamingTraditional client-server based video streaming solutions incur expensive bandwidth provision

cost on the server and therefore these models are not optimized for real time online video

streaming services. The client server model is not highly scalable and is prone to a single point of

failure problem. Providing a scalable streaming service, which is resistant and resilient to failure,

is very expensive in terms of bandwidth, therefore traditionally most streaming services are

delivered through distributed servers content delivery network (CDN) or P2P networks.

This trend has been reversing for over 2 years because the web speed is increasing exponentially.

With the imminent worldwide deployment of 4G broadband internet services bandwidth

constraint might be totally alleviated.

Peer-to-Peer (P2P) networking is a time tested paradigm to build distributed network

applications. Recently, several P2P streaming systems (e.g. Sopcast, P2PStream) have been

deployed to provide live and on-demand video streaming services on the Internet at low server

cost. In Live Media Streaming, the streams are only available at one particular time; while in

video on demand (VoD) streams, the streams are stored on a server and are available to be

transmitted at a user's request. It provides a large subset of VCR functionality, e.g., pause, fast

forward, fast rewind (Amir, 2011).

1.2. Motivation and Problem StatementVideo streaming is set to experience explosive growth in the coming years. According to Cisco

VNI report (2011) by 2012 Internet video will account for over 50 percent of consumer Internet

traffic and this will increase to 62% by 2015; the various forms of video the internet now carries

TV, VoD, Internet Video, and P2Pwill account for 91 per cent of consumer traffic.

Streaming video has overtaken the popularity of P2P networks because as web speed is

increasing, so will the amount of streaming. Rather than concentrate on P2P file sharing, the

video service that will be developed in this project will be an Internet video streaming service.

This project provides an excellent opportunity to research into how video is being deployed over

the internet as a web application.

1.3. Case StudyThe project to be designed is a java based chat server. Although a lot of java based cha server has

been built, none is available that is capable of streaming live video using RTP and RTSP

protocol. This is mainly due to copyright protection laws; therefore the project will be for purely

academic and experimental purposes rather than commercial value. There are various ways by

which video can be streamed online but this thesis will focus on the use of the Java RTP and

RTSP protocol available in recent releases of java suite.

1.4. Project ScopeThere are two main methods of streaming video: Streaming Server and HTTP Streaming. This

project is a web based video streaming service based on a streaming server implementing RTP

protocol so the end user can start watching the file almost as soon as it begins downloading and

therefore be used to broadcast live events or used to share recorded video at. Other forms of

video streaming like P2P, progressive downloading will not be implemented but will be

discussed.

1.5. Project ObjectivesThe objectives of this thesis are listed below

To create a social networking tool that people can use to share memorable fun timebetween themselves.

Build a java based chat server that can be supported on different operating system. Build a Video streaming server into the chat application. The chat server will also have file sharing features.

2. Literature ReviewAs discussed in Section 1 above, there are two main methods of deploying video to viewers over

the internet. These methods are Download and video streaming. This section covers the different

types of video streaming on the internet with particular emphasis Streaming servers and HTTP

streaming. The main focus will be on the architecture of these methods and how they affect the

efficiency and quality of deployment in different operating systems.

Two things are of utmost importance when creating a streaming service and these are the

video file format and the streaming method. This is video players generally do not play all

available formats. It is therefore necessary to sometimes include multiple players or multiple file

formats based on user preference.

2.1. File FormatsThere are many video file formats to choose from when creating video streams. A wide range of

video formats, use different codecs to encode and compress video data and they also have their

own file formats with different extensions like .swf, .wmv, .mp3, and .mp4. The MP4 format is

the most widely used format on internet video because it is supported by YouTube, Flash players

and HTML5 (w3schools, 2012). In order to reach the widest audience, it is sometimes imperative

to create separate files for the different formats. But this is not practically feasible

2.2. Streaming MethodsThere are two ways to view media on the internet (such as video, audio, animations,

etc): Downloading and streaming.

2.2.1. DownloadingMedia downloading is a form of file access which has some pros and cons. When a file is

downloaded, the entire file is saved on the computer before a user can have access and view the

files. Video files accessed this way has the advantage that a user can have such as quicker access

to different parts of the file; the big disadvantage is that user have to wait for the whole file to

downloaded before any of it can be viewed. For small files, this might constitute a small

inconvenience but if the files are large, the delay is unacceptable.

The easiest way to provide downloadable video files is to use a simple hyperlink to the file. A

slightly more advanced method is to embed the file in a web page using special HTML code.

2.2.2. Progressive DownloadingProgressive downloading or pseudo streaming is another common delivery method on the

internet for multimedia objects. It has the same nature of downloading, but provides an option on

the client side to play the object while it is being downloaded rather than wait for the whole

video file to download. Most media players, such as Windows Media Player and Real Player,

support the pseudo streaming mechanism (Lei et al, 2005). A major limit of pseudo streaming

appears when the downloading connection is slow and cannot catch up with the playback speed.

Users cannot jump forward in the stream since the file is downloaded in sequence. This method

therefore simulates true streaming, but doesn't have all the advantages because the client cannot

control where and what to watch in the stream.

2.2.3. Streaming ServersStreaming media works differently from downloading method since the client can start viewing

or watching the file as soon as it begins downloading (Lei et al, 2005; Silverstone and Fourmaux

2007; Amir, 2011). In effect, the file is sent to the user in a more or less constant stream, and the

user watches it as it arrives. The obvious advantage with this method is that no waiting is

involved. Streaming media has additional advantages such as being able to broadcast live events

sometimes referred to as a webcast or netcast. True streaming video are delivered from a

specialized streaming server. Various researches has proven and developed streaming as the

most efficient method for delivery multimedia over the internet (Lei et al, 2005).

With streaming, the playback of a media object can start shortly after the client receives the

initial portion of the object from the streaming server. In addition, streaming provides clients

with a variety of controls during playback, such as pause, rewind, jump, etc. This allows a client

to start or stop the media stream easily at any time. Compared with downloading and pseudo

streaming, the amount of data transferred in streaming is closest to what the client really needs.

Because of its many advantages, streaming is used in various Internet applications today.

Figure 3: Video On Demand Streaming Server2

There have been many different researches into multimedia streaming. While Chesire et al

(2001) measured the streaming media workload in a windows 2000 environment; Almeida et al

(2001) analyzed the workload on the server in an educational environment. A more recent

research by Fernandez et al (2011), focused on creating an adaptive and predictive architecture

for streaming server with the aim of enhancing the overall video quality especially in

environment with low internet bandwidth; by formulating a combination of innovative

congestion control-aware mechanisms and filtering technique

2.3. Streaming Video ServersA streaming media or streaming video server is a specialized application which runs on an

Internet server. This is often referred to as "true streaming", since other methods only simulate

streaming. True streaming has advantages such as:

The ability to handle much larger traffic loads. The ability to detect users' connection speeds and supply appropriate files automatically. The ability to broadcast live events.

There are two ways to have access to a streaming server:

1. Operate you own server (by purchasing or leasing)2. Sign up for a hosted streaming plan with an ISP (Internet Service Provider)

Streaming video servers operate with the Real Time Streaming Protocol to deliver a constant

video stream. This protocol is employed in this thesis and is described in details below.

2.3.1. RTP ProtocolThe Real-Time Streaming Protocol (RTSP) is an application layer protocol that is used for the

setup and control of the either a single or several time-synchronized streams of continuous media

with real time properties. The protocol is used for establishing and controlling media sessions

between end points. It is optimized for live data streams or stored clips which require on

demand and/or real time delivery. It should be noted that RTSP does not typically deliver the

continuous streams itself, but rather defines a medium of set of control for multiple data delivery

and sessions; it provide a means for choosing the delivery channel which can be either TCP or

UDP (multicast, unicast or broadcast) and also define the Real Time Protocol Delivery

mechanism (Schulzrine et al, 2011). RTSP therefore serves as a control protocol, and as a

jumping off point for negotiating transports and negotiating codecs off of servers in a file format

independent way.

Figure 4: RTSP Communication States3

An RTSP session can use multiple transport-level connection such as a TCP connection. During

an RTSP session, a client may open and close multiple reliable transport layer connections to the

server when issuing RTSP requests. Alternatively, it may use a connectionless transport protocol

such as UDP (Vasquez-Brisneo and Vincent, 2007; rstp.org, 2007).

The RTSP server in our architecture is written in Java using jdk1.6.0_25 distribution. It

implements the basic RTSP mechanisms to control the streamed data, but once the session is

established, media streams are sent using RTP over UDP as the transport mechanism as shown

in the diagram below. Java's sophisticated memory management, native support

for threading and concurrency, type safety, made it the program of choice to implement the

server. UDP datagram sockets are established on port 25000. More intricate details and

description are expostulated in Section 3 and Section 4.

The streams created and instantiated by RTSP may use RTP, but the operation of RTSP does not

depend on the transport mechanism used to transport the multimedia file. RTSP is intentionally

similar in syntax and operation to HTTP/1.1 so that extension mechanisms to HTTP can in most

cases also be added to RTSP. However the differences between HTTP/1.1 and RTSP are

expounded below:

The protocol identifier in RTSP is different from that of HTTP/1.1. HTTP is stateless in nature while an RSTP server is a stateful server by default; although,

this can be turned to

RSTP requests can be initiated by both client and server nodes. Different protocols can be used to carry data in an RSTP connection. RTSP is defined to use ISO 10646 (UTF-8) rather than ISO 8859-1, consistent with

current HTML internationalization efforts.

The RTSP Request-URI always contains the absolute URI which is made up of path andhost name bundled together in a header field. HTTP/1.1 on the other hand carries only

the absolute path in the request and puts the host name in a separate header field because

of backward compatibility with a historical blunder.

The protocol supports the following operations:

Retrieval of media from media server: The client can request a presentation descriptionvia HTTP or some other method.

Invitation of a media server to a conference: A media server can be "invited" to join anexisting conference, either to play back media into the presentation or to record all or a

subset of the media in a presentation.

Addition of media to an existing presentation: Particularly for live presentations, it isuseful if the server can tell the client about additional media becoming available.

2.3.2. Real Time ProtocolThe real-time transport protocol (RTP) provides end-to-end delivery services for data with real-

time characteristics, such as interactive audio and video or simulation data, over multicast or

unicast network services. Applications typically run RTP on top of UDP to make use of its

multiplexing and checksum services; both protocols contribute parts of the transport protocol

functionality. However, RTP may be used with other suitable underlying network or transport

protocols. RTP supports data transfer to multiple destinations using multicast distribution if

provided by the underlying network.

RTP itself does not provide any mechanism to ensure timely delivery or provide other quality-of-

service guarantees, but relies on lower-layer services to do so. It does not guarantee delivery or

prevent out-of-order delivery, nor does it assume that the underlying network is reliable and

delivers packets in sequence. The sequence numbers included in RTP allow the receiver to

reconstruct the sender's packet sequence, but sequence numbers might also be used to determine

the proper location of a packet, for example in video decoding, without necessarily decoding

packets in sequence.

RTP consists of two closely-linked parts:

The real-time transport protocol (RTP), to carry data that has real-time properties. The RTP control protocol (RTCP), to monitor the quality of service and to convey

information about the participants in an on-going session. The latter aspect of RTCP may

be sufficient for "loosely controlled" sessions, i.e., where there is no explicit membership

control and set-up, but it is not necessarily intended to support all of an application's
