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 7):
The method of  claim 1 , further comprising coding a root coded block flag for indicating a presence of a non-zero transform coefficient for the block of pixels, wherein when the root coded block flag for the block of pixels is zero, the first flag and the second flag are inferred to be zero and the code word is not encoded.
