Channel reliability dependent Wyner-Ziv video coding using rate adaptive LDPC code with degree-1 syndrome

In distributed video coding (DVC), channel coding technique plays a key role to improve the coding performance. However, many iterative channel coding schemes such as LDPC codes and turbo codes suffer from error floor region, which can give some negative impact to the DVC such as degradation in rate-distortion performance. In this paper, to reduce this error floor problem in rate adaptive LDPC code, large cycle length design and source revealing scheme (channel coding scheme with degree-1 syndrome) are applied to the transform domain Wyner-Ziv coding. The proposed scheme is shown to improve the coding performance.
