Distributed Video Coding Based on Multiple Description
In our paper, we propose a novel distributed video coding (DVC) scheme using the theory of multiple description (MD), in which key frame is encoded by MD codec and transmitted over the corresponding channel. This scheme combines the advantage of DVC as well as robustness of MD, and exploits three different methods to generate multiple descriptions for the key frames that are essential to side information. Experiments demonstrate that it can get better performance than some general DVC methods. Besides, it demonstrates higher robustness in packet-loss channel than general DVC due to the MD algorithm.
