Abstract  Abstract

In one example a device used for coding video data includes video decoder said video decoder is arranged to wherein the area of video based on a conversion coefficient to a block for coding a video block of a conversion coefficient of context even a use by a ciphertext and entropy coding a conversion coefficient. The region can include the first region and the one of the second area the first area comprises the video block and one or more upper conversion coefficient of the 4 * 4 sub block said second area comprises the video block is on the area outside of the first conversion factor.

In one example a device for coding video data includes a video coder configured to determine a context for coding a transform coefficient of a video block based on a region of the video block in which the transform coefficient occurs and entropy code the transform coefficient using the determined context. The region may comprise one of a first region comprising one or more upper-left 4x4 sub-blocks of transform coefficients of the video block and a second region comprising transform coefficients of the video block outside the first region.
