    Abstract: A method by which a video decoding device decodes a video, according to the present document, can comprise the steps of: parsing, from a bitstream, number information related to the number of slices of which the height within a tile of a current picture is explicitly signaled; parsing, from the bitstream, on the basis of the number information, height information related to the height of the slices of which the height is explicitly signaled; deriving the number of slices in the tile on the basis of the number information and the height information; generating prediction samples by predicting the current block of the current picture on the basis of the slices within the tile; generating reconstructed samples on the basis of the prediction samples; and generating a reconstructed picture for the current picture on the basis of the reconstructed samples.

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

    Abstract: A method by which a video decoding device decodes a video, according to the present document, can comprise the steps of: acquiring image information from a bitstream, the image information including a picture header related to a current picture, and the current picture including a plurality of slices; parsing, from the picture header, a first flag indicating whether information necessary for an inter prediction operation is in the picture header and/or a second flag indicating whether information necessary for an intra prediction operation is in the picture header; parsing, from the picture header, the information necessary for the inter prediction operation and/or the information necessary for the intra prediction operation on the basis of the first flag and/or the second flag; and generating prediction samples by performing intra prediction and/or inter prediction for a current block in the current picture on the basis of the information necessary for the inter prediction operation and/or the information necessary for the intra prediction operation.
