A Context-Based Error Detection Strategy into H.264/AVC CABAC
Various error control schemes have been addressed in wireless video stream transmission. By combining an adaptive binary arithmetic coding technique with context modeling, CABAC as a normative part of H.264/AVC has achieved a high degree of adaptation and redundancy reduction. However, error propagation still remains a problem because of the property of arithmetic coding. The presented scheme compares the various error detection methods, and proposes an efficient error detection technique based on CABAC semantics, which is achieved by inserting detective markers denoting by syntax elements. The misdetection probability versus stream size expansion can be easily handled. In addition, placements of markers can vary with regard to specific video content, thus efficiency within this scheme is enhanced. Comparison with other detection scheme is also presented.
