SIGNALING SYNTAX ELEMENTS FOR TRANSFORM COEFFICIENTS FOR SUB-SETS OF A LEAF-LEVEL CODING UNIT |
摘要 |
<p>This disclosure describes techniques for coding transform coefficients for a block of video data. According to these techniques, a video encoder divides a leaf-level unit of video data into a plurality of transform coefficient sub-sets. The video encoder generates, for a sub-set of the plurality of transform coefficient sub-sets, a syntax element that indicates whether or not the sub-set includes any non-zero coefficients. In some examples, the video encoder may selectively determine whether to generate the syntax element for each sub-set. A decoder may read an entropy encoded bit stream that includes the syntax element, and determine whether to decode the sub-set based on the syntax element.</p> |
