Abstract
In one embodiment, the apparatus includes a decoder configured to obtain quantization information of a first block. The first block includes a pixel to be filtered. The decoder is configured to determine a filtering coefficient based on a value obtained from a table using the quantization information, and obtain four successive filtered pixel values based on the filtering coefficient. Two of the four successive filtered pixels are included in the first block and two of the four successive filtered pixels are included in a second block adjacent the first block.
