Abstract
Fine granularity scalability (FGS) in MPEG-4 and some enhanced FGS coding techniques have been studied recently for video streaming. However, a problem of drifting may emerge due to the difference of reference frames used in the encoder and decoder for those enhanced FGS coding schemes. In this paper, we propose incorporating multiframe-based motion compensation into an FGS coding scheme to further improve the coding efficiency and error robustness. It has been shown that the multiple frames based FGS coding scheme has better coding efficiency than the conventional one-frame based FGS video coding, and more importantly, the new one can alleviate the drifting problem significantly. The proposed approach is implemented within a one-loop FGS coding scheme based on an H.26L framework.
