Abstract
Official abstract text for this publication.
In an example, a method includes coding significance information for transform coefficients in a set of transform coefficients associated with the residual video data according to a scan order in one or more first passes. The method also includes coding a first set of one or more bins of information for the transform coefficients according to the scan order in one or more second passes, where the first set of one or more bins are coded in a first mode of a coding process. The method also includes coding a second set of one or more bins of information for the transform coefficients according to the scan order in one or more third passes, where the second set of one or more bins are coded in a second mode of the coding process.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of coding transform coefficients associated with residual video data in a video coding process, the method comprising: coding a sub-set of transform coefficients associated with the residual video data that comprises fewer than all transform coefficients of a block using a plurality of passes, wherein each pass of the plurality of passes comprises a scan of the sub-set of transform coefficients in a scan order, wherein the scan order comprises an or…
