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 44):
A system for sample adaptive offset (SAO) filtering, the system comprising:\n a receiver component configured to receive encoded video data from a storage device; a decoder component coupled to the receiver component, the decoder component further comprising: an entropy decoder component configured to decode an entropy encoded bit stream; an inverse quantization component coupled to the entropy decoder component and configured to perform an inverse quantization function on at least a portion of the decoded bit stream; an inverse transform component coupled to the inverse quantization component and configured to perform an inverse transform component on bit stream data output from the inverse quantization 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 component coupled to the combiner component, the deblocking filter component configured to perform deblocking filtering on the plurality of non-overlapping regions of the reconstructed picture; a SAO filter component coupled to the deblocking filter and configured to perform SAO filtering on the plurality of non-overlapping regions of the reconstructed picture using SAO parameters for each of a plurality of color components extracted from decoded slice data, wherein the SAO parameters for each of the plurality of color components for the associated plurality of the non-overlapping regions and data for the associated plurality of the non-overlapping regions are interleaved in the slice data portion of the decoded bit stream; and a display component coupled to the decoder component and configured to display an SAO filtered reconstructed picture.
