Abstract
In one embodiment, the apparatus includes a decoder configured to obtain quantization information of a first block, obtain a block type of the first block, and compare the quantization information and a threshold value. Loop-filtering is performed by the decoder on four successive pixels by using at least three successive pixels if the quantization information is greater than the threshold value and the type of the first block is an intra-coded block type. Two pixels of the four successive pixels are in the first block and two pixels of the four successive pixels are in a second block adjacent to the first block.
