METHODS AND APPARATUS FOR USING SYNTAX FOR CODED-BLOCK-FLAG SYNTAX ELEMENT AND CODE-BLOCK-PATTERN SYNTAX ELEMENT FOR CAVLC 4:4:4 INTRA, HIGH 4:4:4 INTRA, AND HIGH 4:4:4 PREDICTIVE PROFILES IN MPEG-4 AVC HIGH LEVEL CODING

摘要

PROBLEM TO BE SOLVED: To provide methods and apparatus for using syntax for the coded_block_flag syntax element for the CAVLC 4:4:4 Intra, High 4:4:4 Intra, and High 4:4:4 Predictive profiles in MPEG-4 AVC high level coding.SOLUTION: An apparatus includes an encoder for encoding image data into a resultant bitstream in accordance with an encoding profile that encodes a sample of the image data such that the sample includes two chrominance arrays and a luminance array. Each of the two chrominance arrays has the same height and the same width as the luminance array. The encoder indicates presence of at least one 8×8 block in the resultant bitstream by using the coded_block_flag syntax element.
