Abstract :
Due to the growing interest in video delivery over unreliable channels, the problem of error concealment in video communication is increasingly important. Our goal is to enable the correct decoding of bitstream, on the top of that, have a maximum playable frame rate and video quality. To be able to better combat packet loss, this article proposes a UEP solution in data partitioned H.264 video. Using mathematical expectation we first present the ARUP concept to find an optimal tradeoff between error correction ability of RS code and network capacity. Then we evaluate three different protection schemes. Experimental results show that with the combination of data partition and RS code, our proposal significantly improves the received video quality when packet loss occurs. In the last scheme, our method has at least 10 dB PSNR increase comparing to the stream without RS protection when the packet loss rate is 10%.
