1. A system comprising:
a receiver component configured to receive an encoded bit stream; and
a decoder component coupled to the receiver component, wherein the decoder component comprises:
an entropy decoder component configured to decode the 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 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 and configured to perform deblocking filtering on the plurality of non-overlapping regions of the reconstructed picture; and
a SAO filter component coupled to the deblocking filter component and configured to perform SAO filtering on the deblocked plurality of non-overlapping regions of the reconstructed picture using SAO parameters extracted from a slice data portion of the decoded bit stream,
wherein the SAO parameters for the deblocked plurality of the non-overlapping regions and data for the deblocked plurality of the non-overlapping regions are interleaved in the slice data portion of the decoded bit stream.
