TRANSFORM-SKIP RESIDUAL CODING OF VIDEO DATA

Abstract:

The present disclosure provides systems and methods for transform-skip residual video data coding and decoding. One exemplary method comprises: performing a first pass of scanning a transform coefficient of a sub-block of a video frame, wherein the first pass of scanning comprises: bypass coding a parity level flag for the transform coefficient, the parity level flag indicating a parity of an absolute value of a level of the transform coefficient.
