Distributed source coding
WebA particular case of distributed source coding is distributed video coding where the source is a video sequence. In this kind of architectures, Y may be provided to the decoder using a traditional coding solution such as the MPEG-X or H.26x intra coding standards. The dilemma would then be how to encode X in order to reach optimal performance ... WebOct 14, 2011 · Distributed source coding (DSC) considers the problem of separate compression and joint decompression of multiple correlated sources. Berger and Tung first introduced the multiterminal (MT) source coding problem and studied the region of all possible encoder rate tuples such that the sources are reconstructed under distortion …
