Abstract

In this paper, we devise a procedure that mimics the behavior of a progressive video stream starting from a non progressive one such as H.264/AVC encoded video. This allows one to unequally protect the video data in an efficient way, according to their importance and the network state. The reported results demonstrate the superior performance of the proposed approach in comparison to state-of-the-art methods for resilient transmission of H.264/AVC data. Moreover, the flexibility in terms of redundancy insertion and achieved quality levels, allows one to span different applications, possibly including P2P video streaming.
