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 . |
