Abstract (en)
[origin: WO2006123913A1] The present invention relates to coding of SNR enhancement layer data produced during video signal encoding. The present method determines order or blocks in a picture according to a probability table that is obtained from frequencies of locations where non-zero data exists, scans and codes data on each block to data stream as selecting blocks in the determined order, updates the probability table, re-determines order of blocks in the picture based on the updated probability table, and scans and codes data on each block to data stream just after location where the previous scanning is suspended as selecting blocks in the re-determined order. The present invention increases probability to provide a decoding side with more data that contributes to video quality improvement.
