Abstract:

A joint H.264 rate control and error resilience coding scheme is proposed to overcome constraints of low delay mobile video applications. The estimated transmission error sensitivity (ES) of the current frame and its contained macroblocks (MB) derived in pre-encoding stage are used to adaptively allocate target bits for frame and MB respectively. An importance level is set to each video slice based on the percentage of its contained high ES MBs, and an unequal error protection (UEP) with Turbo-codes is applied to slices based on their importance levels. Simulation shows that our scheme can obtain more than 1dB luminance PSNR gain on average compared with the conventional H.264 rate control and error resilience algorithms.

Key words: video coding, rate control, error resilience
