【Abstract】 According to the data portioning of the H.264 video compression standard,an Unequal Error Protection (UEP) scheme is proposed in this paper. This scheme predicated the packet loss ratio by the feedback information of the wireless channel and adjusts the channel rate for each partition of the H.264 video stream adaptively,Experiments show that this scheme can improve the error robustness of the video stream effectively.更多还原
