1. In a processing device for decoding a sequence of a plurality of pictures, each of the pictures partitionable into one or more coding units, each coding unit coded at least in part according to at least one transform unit as specified in a transform tree, a method of processing the sequence, comprising:
determining, by the processing device, if a size of the transform unit is greater than a minimum transform unit size; if the transform unit size is greater than the minimum transform unit size:
determining, by the processing device, if the transform unit is at a same hierarchical depth as the coding unit associated with the transform unit;if the transform unit is at the same hierarchical depth as the associated coding unit, reading, in a first logical statement executed by the processing device, a flag indicating whether a first chroma transform block has any non-zero coefficients;if the transform unit is not at the same hierarchical depth as the associated coding unit, determining, by the processing device, if a second chroma transform block hierarchically above the first chroma transform block has any non-zero coefficients; andif the second chroma transform block hierarchically above the first chroma transform block has any non-zero coefficients, reading, in a second logical statement executed by the processing device, the flag indicating whether the first chroma transform block has any non-zero coefficients. |
