Abstract

SP(Synchronization-Predictive) frame coding, which enables high efficiency of switching between two video bitstreams with different qualities, is supported by H.264/AVC. And FGS(Fine-Granular-Scalability) coding is supported by MPEG-4 video standard. This paper proposes a solution for combination these two tools with each other so as to adapt to high bandwidth variations of Internet or wireless networks and to low bandwidth variations flexibly for transmitted video streams. Experimental results show that our proposed system outperforms FGS coding by 0.47dB and the H.264/AVC-based video stream switching approach by 0.23dB on average.
