Analysis of side information generation impact on distributed video coding performance

Distributed video coding (DVC) is a relatively new video coding paradigm based on distributed source coding ideas. This approach does not use motion estimation at the encoder side and allows implementing low-complexity encoding schemes. In the DVC decoding procedure turns to generation of side information using key frames and further side information refinement using the principles of error correction coding. The basic approaches to side information generation for DVC are considered in the paper. A new algorithm of side information generation is proposed. An evaluation of rate-distortion performance of the new DVC scheme based on the described algorithm is given.
