CODING AND DECODING OF TRANSFORM SKIPPED BLOCKS

摘要

Video encoder and decoder and methods therein for transform skipped encoding and decoding of blocks of pixels. The methods comprises a modified use of an existing context model associated with transform coefficients for deriving contexts for a bitmask indicating which residual values (i.e. not transform coefficients) in a transform skipped residual block that are greater than one. The methods are applicable to video coding schemes such as HEVC.
