An Integrated Congestion Control and H. 264 Error Resilience Framework for Video Transmission
联合拥塞控制与H.264容错编码的视频传输

When transmitting over the error-prone channels, the compressed video bit-steams are always vulnerable to all kinds of transmission errors. The corrupted parts of the bit-streams may not only affect the reconstruction effect of the current frames, but also cause the error propagation problems both spatially and temporally. So it is really practical to take into account the error-resilience effects in each step of the transmission system. In this paper, we describe a framework for video transmission over the packet-loss channel which features the coordinated operation of the H. 264 error resilience encoding, error concealment algorithms, transport-layer packetization and congestion control mechanisms. We analyze and design the key algorithms of the framework and the experimental results show that our approach works well in different channel conditions.
