Abstract

A scalable video coder generates scalable compressed bitstream, which can provide different types of scalability depend on different requirements. This paper proposes a novel resynchronization method for the scalable video with combined temporal and quality (SNR) scalability. The main purpose is to improve the robustness of the transmitted video. In the proposed scheme, the video is encoded into scalable compressed bit-stream with combined temporal and quality scalability. The significance of each enhancement layer unit is estimated properly. A novel resynchronization method is proposed where joint group of picture (GOP) level and picture level insertion of resynchronization marker approach is applied to insert different amount of resynchronization markers in different enhancement layer units for reliable transmission of the video over error-prone channels. It is demonstrated from the experimental results that the proposed method can perform graceful degradation under a variety of error conditions and the improvement can be up to 1 dB compared with the conventional method.
