Claim Text:
1. A method of decoding video data comprising: selecting a context for decoding a Cb chroma coded block flag from a context set including one or more contexts, wherein selecting the context is based on a transform depth of a transform unit associated with a block of video data, the transform unit comprising a Cr transform block and a Cb transform block; entropy decoding, from a video bitstream, using context adaptive binary arithmetic coding (CABAC) and the selected context, the Cb chroma coded block flag indicating whether the Cb transform block contains non-zero transform coefficients; entropy decoding, from the video bitstream, using CABAC and the selected context, a Cr chroma coded block flag indicating whether the Cr transform block contains non-zero transform coefficients, wherein entropy decoding the Cr chroma coded block flag comprises using the same context set as the Cb chroma coded block flag; and entropy decoding, from the video bitstream, the transform unit associated with the block of video data.
