Claim Text:
1. A method for performing filtering in a video encoding process, the method comprising: storing sets of filter information, wherein the filter information includes SAO information, the SAO information comprising data indicative of offset values; storing mapping information that maps one or more of the sets of SAO information to one or more largest coding units (LCU's) of a frame of video data; signaling one of the sets of SAO information in a bitstream at the LCU level as a LCU level syntax element such that the signaled set of SAO information is directed to and applied to a first LCU; signaling mapping information in the bitstream at the LCU level as a LCU level syntax element such that the signaled mapping information is directed to a second LCU, wherein the first and second LCU's are different LCU's; applying a set of SAO information applied to another LCU to the second LCU based on the mapping information directed to the second LCU; and performing SAO processes for each of the first and second LCU's based on the set of SAO information applied to each LCU.
