Abstract:
A method for sample adaptive offset (SAO) filtering and SAO parameter signaling in a video encoder is provided that includes determining SAO parameters for largest coding units (LCUs) of a reconstructed picture, wherein the SAO parameters include an indicator of an SAO filter type and a plurality of SAO offsets, applying SAO filtering to the reconstructed picture according to the SAO parameters, and entropy encoding LCU specific SAO information for each LCU of the reconstructed picture in an encoded video bit stream, wherein the entropy encoded LCU specific SAO information for the LCUs is interleaved with entropy encoded data for the LCUs in the encoded video bit stream. Determining SAO parameters may include determining the LCU specific SAO information to be entropy encoded for each LCU according to an SAO prediction protocol.

Claim (Index 8):
A video encoding system comprising:\n a dequantizing component configured to perform a dequantizing function on an input bit stream; an inverse transform component coupled to the dequantizing component and configured to perform an inverse transform function on bit stream data output from the dequantizing component; a combiner component coupled to the inverse transform component and configured to combine bit stream data output from the inverse transform component with additional data to form a plurality of non-overlapping regions of a reconstructed picture; a deblocking filter coupled to the combiner component and configured to perform a deblocking function on the plurality of non-overlapping regions to form a plurality of deblocked non-overlapping regions; a sample adaptive offset (SAO) filter coupled to the deblocking filter and configured to: determine SAO parameters for each of a plurality of color components for each of the plurality of deblocked non-overlapping regions wherein the SAO parameters for the plurality of color components each comprise an indicator of an SAO filter type and at least one SAO offset; filter the plurality of deblocked non-overlapping regions using the SAO parameters for the plurality of color components; and an entropy encoder component coupled to the SAO filter and configured to encode the SAO parameters for the plurality of color components and data for the associated plurality of the non-overlapping regions for which the SAO parameters for the plurality of color components are determined in an interleaved manner in a slice data portion.
