摘要： In a video encoding and/or decoding apparatus and/or method, a video encoder partitions a reference image predicted block-wise with at least a filter into blocks in at least one layer, sets a partitioning flag to indicate whether each of the partitioned blocks is subdividable into sub-blocks, sets a filter type to indicate which filter was used for interpolating each of the blocks or sub-blocks, and quadtree-encodes the partitioning flag and the filter type together with the corresponding block or sub-block to generate a quadtree-encoded bitstream. A video decoder reads the partitioning flags and the filter types from the quadtree-encoded bitstream to reconstruct the partitioning flags and the filter types for the corresponding blocks or sub-blocks, generates the blocks or sub-blocks based on the corresponding partitioning flags, and interpolates the generated blocks or sub-blocks on the basis of the corresponding filter types to reconstruct the reference image.
