Recent Advances in Distributed Video Coding
Distributed Video coding (DVC) is a new coding paradigm for video compression mainly based on two major information theory results, Slepian and Wolf’s and Wyner-Ziv theorems. In some major ap-plications such as wireless low power surveillance and multimedia sensor networks, wireless PC cameras and mobile camera phones, it is really a challenge for traditional video coding architecture. For both encoder and decoder, it is necessary to have a low power consumption for some cases. So low power and low complexity encoder are essential to satisfy those requirements. This paper reviews some recent developments of dis-tributed video coding. Slepian and Wolf’s coding is the lossless source coding and Wyner-Ziv coding is a lossy compression with receiver side information. It has been observed that in most of the traditional video coding algorithm such as MPEG,H.263+ or H.264 the encoder has com-plex computational operation rather than the decoder. The distributed video coding is a new kind of video coding which allows a low complexity video encoding where the major part of computational burden is shifted to decoder. DVC is mainly applicable to two areas that is low complex-ity video coding and robust video coding. The dierent techniques are analysed based on certain parameters such as compression rate, decoding and motion compensation.
