Abstract
In one embodiment, the apparatus includes a decoder configured to obtain a coded block pattern of first and second blocks. The coded block pattern is one of a plurality of coded block patterns, the plurality of coded block patterns include an intra-coded block, and the second block is adjacent to the first block. The decoder is configured to obtain a motion vector difference between a motion vector for the first block and a motion vector for the second block, and determine a non-zero filter strength value based on the obtained coded block pattern of the first and second block as first priority and the obtained motion vector difference as second priority. The blocking phenomenon is removed by the decoder according to the filter strength value.
