Abstract  Abstract

In one example a device for coding video data includes a video coder configured to determine whether a transform coefficient of a video block is a DC transform coefficient when the transform coefficient is determined to be the DC transform coefficient of the video block determine a context for coding the transform coefficient based on the transform coefficient being the DC transform coefficient without regard for a size of the video block and entropy code the transform coefficient using the determined context.
