Abstract

The performance of video transmission over wireless channels is limited by the channel noise. Thus many ERROR RESILIENT tools have been incorporated into the MPEG-4 VIDEO compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in a MPEG4 video packet with different channel coding rates based on the rate compatible punctured convolutional (RCPC) codes. However, it is still not powerful enough to achieve a high visual quality over the WIRELESS NETWORKS. To provide more robust MPEG-4 VIDEO transmission over wireless channels, this paper proposes a modified unequal error protection (MUEP) approach based on the content of the video scene. In proposed technique, channel coding rates for motion section of the video packet are determined based on the motion of the video scene. Experimental results show that the proposed technique enhances both subjective visual quality and PSNR about 1.5 dB, comparing to the traditional UEP method.
