Abstract
A video encoding/decoding apparatus includes a video encoder for encoding block mode information indicating whether a block mode of a block to be encoded in a macroblock is a skip mode, partition mode information and skip motion information including index information, encoding at least one of transform type information, CBP information, and delta quantization parameter information of the block according to a combination of the block mode information and the partition mode information, and encoding coefficient information of the block based on the encoded information of the block, and a video decoder for decoding a bitstream to reconstruct block mode information indicating whether a block mode of a block to be decoded is a skip mode, partition mode information indicating whether block is divided into subblocks, and skip motion information including index information, and reconstructing block based on the reconstructed information by using reconstructed skip motion information.
