Distributed video coding for periodic video sequences

Abstract

Distributed Video Coding (DVC) is a very active research field that aims to provide simple encoders, needed by many low resources applications. Unfortunately, all the proposed implementations of this type of coding claim that there is no way to design such a system as described by the distributed Source Coding (DSC) theory. With unconvincing results, such a system can only be combined with conventional coding. In this paper, we will show that there is at least one situation where DVC can be applied directly and efficiently. Thus, we adapt and apply the DVC concept to periodic video sequences (PVS). For these sequences, we will propose a new technique to create the side information (SI), where intra coded frames and motion estimation are no longer needed, which makes this technique very simple and yet very effective. The experimental results show a very good performance, and in some cases, we can even outperform H.264 Inter coding.
