Extensive researches have been conducted to enhance robustness for Internet video transmission. It has been found that feedback channel is an effective tool to provide error recovery ability and it is most suitable for interactive and conversational environments. Multiframe is another useful approach to enhance both coding efficiency and robustness. In this paper, we propose an algorithm which combines feedback channel and multiframe to achieve rapid error recovery ability for H.264 video. Simulation results show that our scheme can best utilize the feedback information. At the end of this paper, its application in conversational services such as Internet videophone is discussed.
