Abstract
As a coding scheme for videos, distributed video coding (DVC) requires the development of motion information. However, motion content is unstable. In this article, we review motion non-stationarity considerations at the DVC encoder and decoder. The encoder focuses on adaptive exploration of the changes of interframe spatial-temporal correlation as the criterion for coding mode selection, where the algorithms are described from two distinct layers of block layer and frame layer. The decoder joins the nonlinear motion information in the side information (SI) generation, to estimate a real motion trajectory and obtain an accurate SI. Decoder motion analysis involves approaches using high-order motion model, global motion model, and local motion model. We also concern about the combination of encoder and decoder in presence of motion non-stationarity algorithms. Finally, the prospects in this field are proposed.
