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.

A sample adaptive offset (SAO) processing apparatus reusing an input buffer and an operation method of the SAO processing apparatus may include a SAO parameter parser to parse SAO parameter information from a bitstream; a SAO parameter adjuster to extract SAO type information and offset information from the parsed SAO parameter information; and a filtering performer to perform filtering on the bitstream based on the SAO type information and the offset information.
