| Abstract: | A unqual error protection scheme for data transmission of H.264 video stream over wireless fading channels is presented,which is realized by rate campatable convolutional coding and a special automatic repeat request strategy.The simulation results show that the unequal error protection can improve the performance and robustness of video transmission over wireless fading channels. |
