摘　　要：Distributing real-time video stream in large scale group communication over Interuet poses several challenging problems due to the complex network dynamics, stringent requirement of delay and loss. This paper proposes a novel peer-to-peer scheme, named TeamCast, to combat with these issues. Constructing multiple diverse application layer multicast （ALM） trees to transmit multiple independent complementary descriptions produced by multiple description coding （MDC） simultaneously, TeamCast improves error resilient ability in the presence of various levels of packet loss caused by unpredictable congestion of Internet and node failure, as well as enlarges system capacity. The results of extensive simulations indicate that TeamCast achieves low latency, scalability, and fault tolerance for the delivery of live media stream.Distributing real-time video stream in large scale group communication over Internet poses several challenging problems due to the complex network dynamics,stringent requirement of delay and loss.This paper proposes a novel peer-to-peer scheme,named TeamCast,to combat with these issues.Constructing multiple diverse application layer multicast (ALM) trees to transmit multiple independent complementary descriptions produced by multiple description coding (MDC) simultaneously,TeamCast improves error resilient ability in the presence of various levels of packet loss caused by unpredictable congestion of Internet and node failure,as well as enlarges system capacity.The results of extensive simulations indicate that TeamCast achieves low latency,scalability,and fault tolerance for the delivery of live media stream.
