In one embodiment, the apparatus includes a decoder configured to obtain a coded block pattern of first and second blocks. The coded block pattern may be one of a plurality of coded block patterns, the plurality of coded block patterns may include an intra-coded block, and the second block may be adjacent to the first block. The decoder is configured to determine whether the first block and the second block have non-zero transform coefficient information if the block type of the first block and the second block is not intra-coded block. A non-zero filter strength value is determined by the decoder based on the obtained coded block pattern of the first and second block and the determination of whether the first block and second blocks have non-zero transform coefficient information, and the blocking phenomenon is removed by the decoder according to the filter strength value.
