    摘要: A method and apparatus for encoding and decoding based on inter prediction are provided. In the encoding method, a current block is encoded by respectively performing intra prediction on the current block and a reference block in a reference picture which corresponds to the current block, and performing inter prediction on the current block based on the results of performing intra prediction. Accordingly, it is possible to reduce the size of data regarding the current block, which is generated as a result of performing inter prediction, thereby improving the compression rate of video data.
