  • Distributed coded video decoding apparatus and method capable of successively improving side information on the basis of reliability of reconstructed data
    Patent number: 8446949
    Abstract: A distributed coded video decoding apparatus includes a key picture decoding unit for reconstructing a key picture, a side information generation unit for generating side information using the key picture and/or previously reconstructed WZ pictures, a side information update unit for updating the side information using the side information and corrected reconstructed video, a channel code decoding unit for decoding quantization symbols, a video reconstruction unit for reconstructing a current WZ picture using the quantization symbols and the side information, and a video correction unit for calculating the reconstructed data reliability using channel code decoded data reliability of the decoded data and/or the reconstructed video reliability determining whether to correct the reconstructed video and determining a correction value based on the calculated the reconstructed data reliability and then correcting the reconstructed video.
