Abstract：When hybrid coded video with motion compensated prediction(MCP) is transmitted over unreliable channels there exists the annoying problem of error propagation.In this paper we analyze the performance of coding efficiency and the distortion caused by propagation error,i.e.,propagation distortion,in multi hypothesis MCP,and give its theoretical performance limit.Then the numerical results under some assumptions are given.Both the theoretical performance and the simulation results of some specific multi-hypothesis MCP schemes under the typical packet loss environment of Internet show that with multi hypothesis MCP both the propagation distortion can be attenuated and the coding efficiency can be improved.
