INTRODUCTION Multimedia Streaming media VOD VOVO

VCR Oriented Scalability Flexibility

Short latency

VOD USING PEER TO PEER NETWORK

An effective content distribution scheme

Existing system

Random access

Disadvantages:

More buffering time will takes when video is Played

A lot of effort has gone into optimizing the distribution of

large video files

The Major problems faced frequently by users in VOD

streaming is a long waiting time for video files to load

Supporting schemes and Techniques

1. Batching and Patching Technique

2. Peer to Peer video streaming scheme:

Cont..

3. Cache and Relay Technique

This scheme should be able to support a dynamic network

It also offer a more efficient approach to support the VCR operations

To avoid the long start-up delay, “cache and relay” technique is used

PROPOSED SYSTEM

In NCECD,Videos are divided into no of Segments and

stored at peers local storage in a distributed manner

Client one can pick any server without additional searches

A network coding equivalent content distribution scheme is used to decrease server stress

Video Transmission using NCECD

Interleaving Distribution of Segments

Advantages

Video files are divided into number of

segments and distributed in effective manner

Loading time and buffering time will be reduced, Server

offline problem also solved

Server Load balancing problems will be solved

• Admin It receives the request from clients and

processes it, sends the requested video

corresponding to client bandwidth.

• Client It send the request to the server, request

contains requested file, available bandwidth

of client and receives the video based on its

available bandwidth.

Modules

Conclusion

The proposed navel data distribution scheme called NCECD to

provide interactive VOD services in a P2P network

It applies network coding technology generating several encoded

blocks.

The Streaming quality is reasonably good with asynchronous

request & frequent VCR Operations
