Abstract
In this paper, a new CAVLC decoding architecture with a soft-input design concept is proposed. The soft-decision information was introduced to localize the erroneous position at macroblock (MB) levels. Specifically, the minimal square difference between the received soft streams and decoded codewords was compared and selected. The corrupted MBs can be early detected and thereby concealed from neighboring pixels. Therefore, more than 1dB of PSNR gain can be achieved under the 2.7times10-3 of bit error rates
