Methods and apparatus for using syntax for the coded

1. A method, comprising:

encoding image data into a resultant bitstream 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 encoding comprises

indicating 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 coefficients are present in the at least one 8×8 block, and

indicating 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.

2. The method of claim 1 , wherein the encoding profile is any of a High 4:4:4 Intra profile and a High 4:4:4 Predictive profile.

3. The method of claim 1 , wherein the first syntax is a coded block pattern syntax.

4. An apparatus comprising one or more processors and at least one memory, the one or more processors being configured to:

decode 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 one or more processors are configured to:

determine 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 coefficients are present in the at least one 8×8 block, and

determine 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.

5. The apparatus of claim 4 , wherein the encoding profile is any of a High 4:4:4 Intra profile and a High 4:4:4 Predictive profile.

6. The apparatus of claim 4 , wherein the first syntax is a coded block pattern syntax.

7. A non-transitory computer readable medium having stored thereon an encoded bitstream, the encoded bitstream comprising:

image data encoded into a resultant bitstream 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;

a first syntax encoded to indicate a presence of non-zero transform coefficients for the at least one 8×8 block in the resultant bitstream, the first syntax permitting 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 coefficients are present in the at least one 8×8 block; and

additional syntax, different from the first syntax, encoded to indicate 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.

8. The medium of claim 7 , wherein the encoding profile is any of a High 4:4:4 Intra profile and a High 4:4:4 Predictive profile.

9. The medium of claim 7 , wherein the first syntax is a coded block pattern syntax.
