Paper Abstract

Current video coding techniques have various features to enable robust transmission of compressed video data over noisy channels. Among them, the use of resynchronization markers is an essential way to prevent spatial error propagation. In this paper, we propose an optimal approach for placement of resynchronization markers for video communication over noisy channels. Given the number of resynchronization markers assigned to the current frame, we optimally decide the position of each marker in a rate-distortion sense. The proposed method takes into account the channel condition and the expected distortion at the decoder, and incorporates these informations into a rate-distortion framework. Some assumptions and the Viterbi algorithm are employed in order to reduce the complexity of the rate-distortion problem. Various simulation results are shown to justify the performance improvement achieved by the proposed method.
