Abstract

See full text

Video encoder and decoder and methods therein for transform skipped encoding and decoding of blocks of pixels. The methods comprise 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.
