Abstract:
A method for coding the coded block flags of individual transform blocks in a video coding system is provided. The method improves coding efficiency by jointly signaling the CBF values of Cb transform blocks and Cr transform blocks from a transform unit or coding unit. A single syntax element cbf_chroma is used to jointly code the CBF values of a pair of the collocated Cb and Cr transform blocks from a transform unit.

Claim (Index 11):
An electronic apparatus comprising:\n a video encoder circuit capable of:\n receiving a block of pixels comprising a luma component, a first chroma component, and a second chroma component; \n encoding the block of pixels as transform coefficients; \n encoding first and second flags as a code word, wherein the first flag indicates a presence of a non-zero transform coefficient for the first chroma component and the second flag indicates a presence of a non-zero transform coefficient for the second chroma component, wherein the code word has different lengths for different combinations of values of the first and second flags; and \n storing the encoded code word and the encoded transform coefficients in a bitstream.
