Abstract: The present invention relates to the encoding and decoding of image information. According to the present invention, the decoding method comprises the steps of: entropy-decoding received information; performing inter prediction on a current block based on the entropy-decoded information; and restoring images by using the prediction results, wherein, in the inter prediction step, a skip mode or merge mode is applied to the current block and movement information of the current block may be determined based on the movement information of a neighboring block of the current block.

Abstract: An image encoding/decoding method and apparatus are provided. An image decoding method includes obtaining inter prediction information of a current block and wraparound information from a bitstream, and generating a prediction block of the current block based on the inter prediction information and the wraparound information. The wraparound information may include a first flag specifying whether wraparound motion compensation is enabled for a current video sequence including the current block. The first flag may have a first value specifying that the wraparound motion compensation is disabled, based on that one or more subpicture, which is coded independently and has a width different from a width of a current picture, is present in the current video sequence.

Abstract: A video decoding method performed by a video decoding apparatus, according to the present document, comprises: parsing number information about the number of slices of which heights are explicitly signaled in a tile of a current picture from a bitstream; parsing height information about the heights of slices of which heights are explicitly signaled from the bitstream based on the number information; deriving the number of slices in the tile based on the number information and the height information; and decoding the current picture based on the slices in the tile, wherein the height information includes the same number of syntax elements as a value of the number information, and based on the value of the number information being n, the heights of a 0th slice to an n−1th slice in the tile may be derived based on the syntax elements.
