Method and apparatus using the syntax of coded_block_flag syntax element and coded_block_pattern syntax element of CAVLC4: 4: 4Intra profile, HIGH4: 4: 4Intra profile, and HIGH4: 4: 4 Predictive profile in MPEG-4 AVC high-level coding

摘要

There are provided 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. 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 a same height and a same width as the luminance array. The encoder indicates a presence of at least one 8×8 block in the resultant bitstream using a syntax element.
