Abstract: A method of context-based adaptive binary arithmetic decoding for syntax elements of a coding unit coded by intra prediction is disclosed. The method includes receiving binary arithmetic coded bins associated with the coding unit, the coded bins includes a first part comprising regular bins associated with prediction units (PUs) partitioned from the coding unit and a second part comprising bypass bins associated with each PU, wherein the regular bins relate to an indication of intra prediction mode selection associated with each PU and the bypass bins relate to an index for a most probable mode and/or a remaining prediction mode associated with each PU; determining a first codeword comprising the regular bins and corresponding to a first syntax element for each PU; determining a second codeword comprising the bypass bins and corresponding to a second syntax element for each PU; and providing the first and second syntax elements for each PU.
