Abstract
The present disclosure relates to a video encoding/decoding apparatus and method, in which skip information indicating whether a block is a skip block is encoded, partition information of the block and skip motion information of the block are encoded or prediction information of the block containing the partition information of the block and intra prediction mode information or motion information are encoded according to the skip information, residual signal information of the block is predictive-encoded based on the prediction information and the transform information, and an encoded signal is reconstructed. The method and the apparatus can improve the video compression efficiency by efficiently encoding the encoding information used for the video encoding and selectively using various encoding methods and decoding methods in encoding the video.
