The invention discloses a method, a system and a mobile terminal device for MBMS mobile TV stream repair, which improves the error resilient performance of the entire application layer bitstream. The technical solution includes: signaling interaction between UE and BMSC center, UE receive MBMS broadcast / multicast stream; UE in the physical layer data link layer / BER of the received MBMS broadcast / multicast stream detection, feedback error location; UE receives the broadcast / multicast stream into MBMS the media data buffer, the error in the upper protocol layer detection; UE decision based on error detection results in which data buffer part requires retransmission, the required bit stream to inform the repair server and send repair request; repair server with unicast transmission of streaming media streaming media UE received repair; repair package, into the media data UE buffer, merged into streaming media stream, and finally stream parsing, decoding and playback. The invention is applied to the field of mobile communication.
【技术实现步骤摘要】
【技术保护点】
一种MBMS手机电视流式修复的方法,包括: (1)在移动终端和多媒体广播组播业务中心之间进行信令交互后,移动终端接收MBMS广播/组播码流; (2)移动终端在物理层/链路层上对接收到的MBMS广播/组播码流的数据进行误码检测,反 馈误码位置; (3)移动终端把接收到的MBMS广播/组播码流放入媒体数据缓冲中,在上层协议层中进行误码检测; (4)移动终端根据误码检测的结果决定缓冲内哪些数据部分需要重传,把所需要的码流告知修复服务器并发送修复请求; ( 5)修复服务器响应来自移动终端的修复请求,以单播的方式发送流媒体修复包; (6)移动终端收到流媒体修复包后,放入移动终端的媒体数据缓冲中,合并到流媒体码流,最后进行码流解析、解码和播放。
