In this work, we present an adaptive unequal loss protection (ULP) scheme for H264/AVC video transmission overlossy networks. This scheme combines erasure coding, H.264/AVC error resilience techniques and importance measures in videocoding. The unequal importance of the video packets is identifiedin the group of pictures (GOP) and the H.264/AVC data partitioning levels. The presented method can adaptively assign unequal amount of forward error correction (FEC) parity acrossthe video packets according to the network conditions, such as the available network bandwidth, packet loss rate and average packet burst loss length. A near optimal algorithm is developed to dealwith the FEC assignment for optimization. The simulation resultsshow that our scheme can effectively utilize network resources such as bandwidth, while improving the quality of the video transmission. In addition, the proposed ULP strategy ensures graceful degradation of the received video quality as the packet loss rate increases.
