In order to be able to better cope with packet loss, H.264/AVC, besides offering superior coding efficiency, also comes with a number of error resilience tools. The goal of these tools is to enable the decoding of a bitstream containing encoded video, even when parts of it are missing. On top of that, the visual quality of the decoded video should remain as high as possible. In this paper, we

Experimental results will show that using data partitioning can significantly improve the quality of a video sequence when packet loss occurs. However, this is only possible if the channel used for transmitting the video allows selective protection of the different data partitions. In the most extreme case, an increase in PSNR of up to 9.77 dB can be achieved. This paper will also show that the overhead caused by using data partitioning is acceptable. In terms of bit rate, the overhead amounts to approximately 13 bytes per slice. In general, this is less than 1% of the total bit rate. On top of that, using constrained intra prediction, which is required to fully exploit data partitioning, causes a decrease in quality of about 0.5 dB for high quality video and between 1 and 2 dB for low quality video.
