METHODS FOR SIGNALING RESIDUAL CODING METHOD OF TRANSFORM SKIP BLOCKS

Abstract:

The present disclosure provides methods of signaling residual coding method for transform skip blocks. An exemplary method includes: determining, based on a first flag, whether to signal a slice residual coding flag in a slice header, wherein the slice residual coding flag indicates whether transform-skip residual coding is enabled for one or more transform-skip (TS) or block-DPCM (BDPCM) coded blocks in a slice associated with the slice header; and processing the slice based on the determination.
