Abstract :
Nowadays, TV broadcasting has found its application in mobile terminal, however, due to the prediction structure of video coding standards, compressed video bitstreams are vulnerable to wireless channel disturbances for real-time transmission. In this paper, we propose a novel temporal error concealment method for mobile TV sequences. The proposed ordering methods utilizes continuity feature among adjacent frames, so that both inter and intra error propagation are alleviated. Combined with our proposed fuzzy metric based boundary matching algorithm (FBMA) which provides more accurate distortion function, experiment results show our proposal achieves better performance under error-prone channel, compared existing error concealment algorithms.
