Abstract:
The disclosure provides a sample adaptive offset (SAO) encoder. The SAO encoder includes a statistics collection (SC) block and a rate distortion optimization (RDO) block coupled to the SC block. The SC block receives a set of deblocked pixels and a set of original pixels. The SC block categorizes each deblocked pixel of the set of deblocked pixels in at least one of a plurality of band and edge categories. The SC block estimates an error in each category as difference between a deblocked pixel of the set of deblocked pixels and corresponding original pixel of the set of original pixels. The RDO block determines a set of candidate offsets associated with each category and selects a candidate offset with a minimum RD cost. The minimum RD cost is used by a SAO type block and a decision block to generate final offsets for the SAO encoder.

Claim (Index 8):
The method of  claim 7 , wherein:\n when the set of deblocked pixels corresponds to the luma component of the current LCU, the candidate offsets associated with the minimum band cost are candidate offsets corresponding to the luma minimum band cost and the candidate offsets associated with each edge category used to generate the edge SAO types are candidate offsets corresponding to each luma edge cost; and when the set of deblocked pixels corresponds to the chroma component of the current LCU, the candidate offsets associated with the minimum band cost are candidate offsets corresponding to the chroma minimum band cost and the candidate offsets associated with each edge category used to generate the edge SAO types are candidate offsets corresponding to each chroma edge cost.
