ABSTRACT:
A method, an apparatus, and a method to encode a block in a picture of a time sequence of pictures such as video. The method includes selecting the mode for coding the block, one of the modes being to code the block as skipped. The method further includes limiting the number of consecutive times a particular block is coded as skipped without re-setting the quantization level to a relatively fine level of quantization and re-selecting the mode.
