Multiterminal Source Coding Based Multicast of H.264 Encoded Video over Heterogeneous Networks

In MTSC, correlated sources are separately encoded but jointly decoded. With appropriate modeling of all kinds of correlation among three non binary correlated sources, in this paper we propose a method for performing IMTSC among three sources. Due to the possibility of providing an approach for practical code design for more than two correlated sources in IMTSC/CEO setup, the multicast system based on multiterminal source coding is applied to the cases with three servers. At severs IMTSC is implemented via the framework of Slepian-Wolf coded quantization. Experimental results with data, image and video signals show the superiority of our proposed method over the conventional solutions and over multimedia multicast based on multiterminal source coding with two servers. In addition, the advantages of parallel downloading from multiple servers such as robustness to a server failure and security are improved with increasing the number of servers
