H.264 Standard Based Side Information Generation In Wyner-ziv Coding

Abstract

The traditional video coding involves a high complexity encoder and relatively low complexity decoder. The complexity of the encoder is mainly due to motion estimation [3] and other prediction techniques employed . There is a new paradigm emerging in video coding - Distributed video coding (DVC). This is based on Slepian-Wolf and Wyner-Ziv6 theorems. In Wyner-Ziv video coding, encoder is less complex compared to the decoder. The decoder is very complex due to prediction involved for side information (SI) generation. There is lot of research done previously on linear density parity check codes (LDPC) and H.263 standard based SI generation for Wyner-Ziv coding. In our approach, we consider LDPC codes for error control and H.264 standard based SI generation. The basic Wyner-Ziv encoder and decoder are implemented to test this method. This is then compared against other SI generation methods.
