Abstract: This disclosure describes techniques for coding video data. As one example, this disclosure describes a coded block pattern (CBP) for a coding unit (CU) of video data that indicates whether or not each of a luminance component (Y), a first chrominance component (U), and a second chrominance component (V) include at least one non-zero coefficient. According to another example, this disclosure describes a CBP that indicates whether respective blocks of a CU include at least on non-zero coefficient. The CBP described herein may be mapped to a single variable length code (VLC) code word. The VLC code word may be used by a coder to code the CU of video data.
