摘要： A video encoding apparatus includes a candidate block type configuration unit for configuring block type candidates for encoding an image by using variable sized macroblocks; a video encoder for encoding an input image for each block type candidate; and a block type determiner for determining a block type based on encoding costs by the block type candidate, and generating a bitstream including image data encoded by the determined block type and information for the determined block type. Determining the block type to match the image characteristics enables combinations of diverse modes such as a large block and macroblock size, a minimum subblock size, available divisional block type, prediction mode type within a macroblock, and so on to achieve more effective encoding and decoding of high resolution images.

摘要： Video encoding/decoding apparatus includes video encoder and video decoder. Video encoder generates predicted subblocks by predicting subblocks into which macroblock is divided, generates residual subblocks by subtracting predicted subblocks from subblocks, generates quantized transform coefficients by transforming and quantizing residual subblocks by using transform selected according to size of subblock, generates encoded video data by encoding quantized transform coefficients, and selectively calculates and determines encoding cost when determining encoding mode for at least one of motion vector, transform type, prediction mode, and block type for subblocks. Video decoder reconstructs partition type information, motion information, transform type information, and quantized transform coefficients by decoding encoded data, reconstructs residual subblocks by inverse-quantizing and inverse-transforming quantized transform coefficients by using transform identified by transform type information, generates predicted subblocks by predicting subblocks identified according to partition type information by using motion information, and reconstructs subblocks by adding predicted subblocks and residual subblocks.
