Efficient Distributed Video Coding based on principle of syndrome coding

Abstract

Distributed Video Coding (DVC) is a new video coding paradigm, the main objective of which is to reduce the encoder complexity to support a separate class of uplink-friendly applications like wireless video applications, besides achieving the rate-distortion performance of conventional video coders. In this paper, we describe and present the simulation results of the video coding method based on the principle of distributed source coding using Golay codes and then propose an improvement to it. In this, the side information is improved by performing a very coarse motion search at the encoder and transmitting the position of the side information block as the hash information to the decoder, which will help the decoder to perform motion estimation.
