| Abstract: | As a new video coding paradigm,distributed video coding(DVC) has lower encoding complexity and higher robustness to transmission error than conventional video coding.However,its compression ratio was comparatively low and highly dependent on group-of-pictures(GOP) size.A combined video coding scheme was proposed by introducing H.264 coding into typical pixel domain Wyner-Ziv(PDWZ) coding.The coder has a parallel encoding and iterative decoding structure,in which a predictive coding scheme and a novel side-i... |
