Abstract :
Distributed Video Coding (DVC) is a new coding paradigm based on two major information theory results namely the Slepian-Wolf (1973) and Wyner-Ziv(1976) theorems. Slepian-wolf coding is the lossless source coding and Wyner-Ziv coding is the lossy coding with receiver side information. Distributed Video Coding allows the implementation of lightweight encoders and complex decoders. This is the dual to conventional video coding such as MPEG or AVC/H.264 where the encoder has to carry most of the computational burden. There are various practical solutions proposed to address the two areas where DVC is applicable. These areas are low complexity video coding and robust video coding. These solutions are compared based on techniques used for compression, rate control, decoding and motion estimation.
