    摘要: An apparatus and method for in-loop filtering based on a largest coding unit (LCU) to reduce an external memory access bandwidth. An in-loop filter may include an external memory to store decoded frames, an internal memory to store pixels in use for deblocking filtering and sample adaptive offset filtering, a horizontal deblocking filter to perform deblocking filtering on input pixels in a horizontal direction with respect to vertical edge boundaries within an input area, a vertical deblocking filter to perform deblocking filtering in a vertical direction with respect to horizontal edge boundaries within the input area, and a sample adaptive offset filter to perform sample adaptive offset filtering.
