An unequal error protection (UEP) technique based on motion information of video bitstreams compressed by H.264/AVC standard is proposed. Motion activities of macroblocks in a frame are analyzed, and those having high effects on the video performance are extracted. Suitable forward error-correcting codes with different rates are constructed according to the importance of macroblocks and frames. Simulation results show that the proposed technique significantly improves the video quality, while maintaining a similar overall code rate in comparison with other UEP techniques.
