DETERMINING CONTEXTS FOR CODING TRANSFORM COEFFICIENT DATA IN VIDEO CODING |
摘要 |
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 4×4 sub-blocks of transform coefficients of the video block and a second region comprising transform coefficients of the video block outside the first region.
