Abstract
Official abstract text for this publication.
A method for signaling sample adaptive offset (SAO) band offset syntax elements in a video encoder is provided that includes receiving a plurality of band offset syntax elements, entropy encoding an absolute value of a magnitude of each band offset syntax element in a compressed video bit stream, and entropy encoding a sign of each non-zero band offset syntax element in the compressed video bit stream following the absolute values of the magnitudes.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for sample adaptive offset (SAO) filtering and SAO parameter signaling, the method comprising: determining band sample adaptive offset (SAO) parameters for at least one of a plurality of non-overlapping regions of a reconstructed picture, applying band SAO filtering to the at least one of a plurality of non-overlapping regions of the reconstructed picture according to the determined band SAO parameters; and entropy encoding the determined band S…
