Claim:
1. A method of applying deblock filter (DF) processing and sample adaptive offset (SAO) processing to reconstructed video data, the method comprising: generating reconstructed video data by decoding a video bitstream using entropy decoding, inverse scaling, inverse quantization, inverse transform, intra/inter prediction or a combination thereof; applying the DF processing to a current block of reconstructed video data to generate DF output data corresponding to the current block, wherein the DF processing is performed using a DF processing module and deblocking status is determined during said applying the DF processing; and applying status-dependent SAO processing to one or more pixels of the DF output data corresponding to the current block according to the deblocking status, wherein the status-dependent SAO processing is performed using a SAO processing module, and the status-dependent SAO processing comprises SAO processing, partial SAO processing, and no SAO processing; wherein the deblocking status indicates whether DF-processed pixels needed by the SAO processing are available; and when the status-dependent SAO processing performs the partial SAO processing according to the deblocking status, the partial SAO processing is performed under a condition that a portion of the DF-processed pixels needed by the SAO processing is not available yet.
