Hd Video Transmission Over Wireless Network Using Batching And Patching Technique

Abstract In recent advances the high speed video transmission over the wireless network has gained popularity among the users. To gain the improved quality of the video on the receiver side without time delay on multiple users accessing the server at the same time is being the challenging task. To transmit the video on wireless network the VIDEO ON DEMAND VoD system and services are used. A video on demand system can be designed with centralized networked and distributed are the three major network configurations The VoD system on the internet is categorized into three approaches clientserver and peer to peer. A true video on demand system provides the users with the freedom to select videocontent at any time and to perform VCR-like user interactions. Though the true video on demand supports full interactivity with potential to start immediately when requested with full VCR functionality of fast forward pause rewind and play the video. The VoD requires a dedicated video stream for each customer request incoming customer requests result in a significant load on the server and network resources. This is due to the high bandwidth and long duration of video content. Thus we propose a NETWORK CODING EQUIVALENT CONTENT DISTRIBUTION NCECD scheme in which the video will be divided into the segment and the segment is also further divided into blocks.Then the blocks are distributed to various peers for local storage.In existing methodthe new client can only search for parent peers which consist of that specific segment.But herethe NCECD uses the network coding to cache equivalent contentso that the new client can pick any parent without any additional search. Second we review the bandwidth-saving streaming schemes such as broadcasting batching patching and merging which use multicast streaming technologies and user buffer memory.
