Abstract:
This disclosure relates to techniques for performing sample adaptive offset (SAO) processes in a video coding process. A video coder may store sets of SAO information. The SAO information may include data indicative of offset values. The video coder may also store mapping information that maps at least some of the sets of SAO information for one or more sequence partitions of a frame of video data. Additionally, the video coder may perform the SAO processes for one of the partitions of the frame based on the stored SAO information and the stored mapping information.
