Abstract :
This paper proposes a novel scheme for distributing MPEG-coded video over a best-effort heterogeneous network, such as the Internet. The key contributions of the proposed scheme are: error recovery using smart retransmissions and adaptive playback point; and dynamic adjustment of video reception rate at the receivers using a hierarchical control mechanism. This paper focuses on the first feature. The protocols are developed on the Internet and the performance of the system has been measured on the Mbone. Some results from the measurement are presented and evaluated in this paper
