Abstract:
A device for coding video data is configured to code a first syntax element, wherein a value for the first syntax element indicates whether there is at least one non-zero transform coefficient level associated with a first block of video data; determine a context for a second syntax element based on the value for the first syntax element, wherein the second syntax element indicates coding mode information for a second block of video data; and code the second syntax element based on the determined context.
