Image filtering equipment and procedure, and video coding / decoding equipment and procedure that employs the same

摘要

A video decoding device comprising: a decoder (910) for obtaining the information of the type of block to determine the size of the current block to be decoded, the information of the type of transformed / quantized and of the residual block transformed / quantified by decoding of the encoded data; a unit of quantification / inverse transformation (930) for reconstructing a residual block by means of the quantification / inverse transformation of the residual block transformed / quantified according to the transform sizes of the transformed blocks determined by the information of the type of transformed / quantification, where the transform sizes of the transform blocks are selected with a range equal to or less than the size of the residual block, depending on the information of the type of transform / quantification; a predictor (940) to generate a planned block by predicting the current block, where the planned block is generated by combining planned subblocks that are generated by dividing the current block into subblocks and predicting the respective subblocks; an adder (950) to reconstruct the current block by adding the reconstructed residual block and the intended block; and a filtering unit (960) for filtering the transform limit between the transform block in the current reconstructed block and an adjacent transform block when using the transform / quantization type information.
