Adaptive Intra Refresh for Robust H.264/AVC Transmission
B. SONG, Hao Qin, Xianyang Jiang, L. MA · IEICE Transactions on Communications · 2008
An intra refresh matrix, which models the importance of each macroblock, is first created. This matrix can be used to decide the coding mode of the macroblocks. The proposed technique can greatly improve the decoded video quality over the variable and error-prone channel with high packet loss rate.
