Abstract
A deblocking filtering apparatus and method based on raster scanning is provided. The deblocking filtering apparatus may include a boundary determining unit to determine whether at least one of a vertical edge boundary and a horizontal edge boundary of a block corresponds to at least one of a coding unit (CU) boundary, a transform unit (TU) boundary, and a prediction unit (PU) boundary, a boundary strength (BS) computing unit to compute a BS value for at least one of the vertical edge boundary and the horizontal edge boundary when at least one of the vertical edge boundary and the horizontal edge boundary of the block corresponds to at least one of the CU boundary, the TU boundary, and the PU boundary as a result of the determining, and a filtering performing unit to perform deblocking filtering on at least one of the vertical edge boundary and the horizontal edge boundary.
