Abstract
Data partitioning in H.264 extended profile video coding enables unequal error protection. Its performance can be improved if the decoder tries to also decode packets containing errors. We propose a soft-input sequential decoding algorithm for the prediction residuals encoded in low-priority packets. Information from the decoding process is then used to control additional error concealment. This combined technique provides significant PSNR gains compared to a simple packet-loss scenario.
