摘要： Disclosed herein are a decoding method and apparatus and an encoding method and apparatus that perform inter-prediction using a motion vector predictor. For a candidate block in a col picture, a scaled motion vector is generated based on a motion vector of the candidate block. When the scaled motion vector indicates a target block, a motion vector predictor of the target block is generated based on the motion vector of the candidate block. The motion vector predictor is used to derive the motion vector of the target block in a specific inter-prediction mode such as a merge mode and an AMVP mode.

摘要： Disclosed herein are a video decoding method and apparatus and a video encoding method and apparatus. In video encoding and decoding, multiple partition blocks are generated by splitting a target block. A prediction mode is derived for at least a part of the multiple partition blocks, among the multiple partition blocks, and prediction is performed on the multiple partition blocks based on the derived prediction mode. When prediction is performed on the partition blocks, information related to the target block may be used, and information related to an additional partition block, which is predicted prior to the partition block, may be used.

摘要： Disclosed herein are a video decoding method and apparatus and a video encoding method and apparatus. In the encoding and decoding of a video, a prediction mode may be selected from among multiple prediction modes using prediction mode information for a target block, and prediction may be performed on the target block based on the selected prediction mode, wherein the prediction mode information includes information related to a reference block, and wherein the reference block comprises one or more of a spatially neighboring block that is spatially adjacent to the target block and a temporally neighboring block that is temporally adjacent to the target block. When the selected prediction mode includes a plurality of prediction modes, a prediction mode to be used for prediction of the target block may be decided on among the plurality of selected prediction modes through signaling of the prediction mode decision information.

摘要： Disclosed herein are a video decoding method and apparatus and a video encoding method and apparatus. Coding decision information of a representative channel of a target block is shared as coding decision information of a target channel of the target block, and decoding of the target block is performed using the coding decision information of the target channel. Since the coding decision information of the representative channel is shared with an additional channel, repeated signaling of identical coding decision information may be prevented. By means of this prevention, the efficiency of encoding and decoding of the target block or the like may be improved.
