This paper analyzes the low bit rate video transmission standards and technologies which support multi-frame prediction encoding,such as H.26L or H.264. In the process of real-time communication in video,if use the multi-reference picture selection technique（MRPS）for error control to ensure the communication quality, the memory of the decoder reference frame number of the effective scheduling and control will reduce the computational complexity decoding. Simulation results show that compared with RPS Technology,under the same video quality,this technology reduces the complexity of decoding algorithms,data compression more efficient than conventional reference picture selection technique（SRPS）,slightly lower than MRPS technology.
