Abstract:
1. A method of decoding an image, the method comprising: obtaining prediction mode information of a current block from a bitstream; obtaining motion vector predictor candidates of the current block using a block co-located with the current block in a temporal reference picture in direction List obtaining a motion vector predictor of the current block among the obtained motion vector predictor candidates based on information indicating a motion vector predictor used for the current block; and obtaining a motion vector of the current block based on the obtained motion vector predictor and a differential vector obtained from the bitstream, wherein the image is split into a plurality of maximum coding units according to an information about a maximum size of a coding unit, a maximum coding unit, among the plurality of maximum coding units, is hierarchically split into one or more coding units of depths including at least one of a current depth and a lower depth, and a current coding, unit of the current depth is one of rectangular data units split from a coding unit of an upper depth.
