Abstract:
1. A method, comprising: decoding image data from a bitstream previously encoded in accordance with an encoding profile that encodes at least one 8×8 block of the image data such that the at least one 8×8 block includes two chrominance arrays and a luminance array, each of the two chrominance arrays having a same height and a same width as the luminance array, wherein said decoding comprises determining a presence of non-zero transform coefficients for the at least one 8×8 block in the resultant bitstream using a first syntax, which permits selectively disabling an application of context adaptive binary arithmetic coding (CABAC) to the at least one 8×8 block based on whether the non-zero transform coefficient is present in the at least one 8×8 block, and determining a presence of non-zero transform coefficients for each of the two chrominance arrays and the luminance array of the at least one 8×8 block in the resultant bitstream using additional syntax different from the first syntax.
