Abstract

The present invention relates to a video encoding/decoding apparatus and method. The video encoding/decoding apparatus according to one embodiment of the present invention comprises: a video encoder that generates predicted sub-blocks by predicting sub-blocks into which a macro block is divided, generates residual sub-blocks by subtracting the sub-blocks and the predicted sub-blocks, generates quantized transform coefficients by transforming and quantizing the residual sub-blocks using a transformation scheme which is selected by the size of the sub-block, generates video data encoded by encoding the quantized transform coefficients, and selectively calculates and obtains an encoding cost when an encoding mode is determined for at least one of the block type, prediction mode, transformation type and motion vector for the divided sub-blocks; and a video decoder that restores information about the division type, motion and transformation type as well as the quantized transform coefficients, restores the residual sub-blocks by performing the inverse-quantization and inverse-transformation on the quantized transform coefficients following a transformation scheme which is identified by the transformation type information having been restored, generates predicted sub-blocks, on the basis of the motion information having been restored, by predicting sub-blocks which are identified by the division type information having been restored, and restores sub-blocks by subtracting the predicted sub-blocks and residual sub-blocks.
