    摘要： Deblocking filter used in a video encoder/decoder based on a multilayer. In deciding a deblocking filter strength when performing a deblocking filtering with respect to a boundary between a current block coded by an intra-BL mode and its neighboring block, it is determined whether the current block or the neighboring block has coefficients. The filter strength is decided as a first filter strength if it is determined that the current block or the neighboring block has the coefficients, and the filter strength is decided as a second filter strength if it is determined that the current block or the neighboring block does not have the coefficients. The first filter strength is greater than the second filter strength.

    摘要： A method and apparatus for encoding and decoding a video signal by extending an application of directional intra-prediction. When performing a directional intra-prediction during video data encoding, a second block in a frame is searched in order to predict information of a first block included in the video data from the second block existing in the same frame as the first block, a residual between information included in the searched second block and the information included in the first block is calculated, and the calculated residual is encoded. The second block exists in a position adjacent to the first block, and the first block refers to the second block in a third direction existing between a first direction and a second direction that are adjacent to each other for use in the directional intra-prediction.
