    Abstract: A video signal decoding device comprises a processor, wherein: the processor decodes a sequence parameter set (SPS) raw byte sequence payload (RBSP) syntax included in a bitstream of a video signal, and decodes the bitstream on the basis of the decoding result of the SPS RBSP syntax; the SPS RBSP syntax includes a first syntax element related to the number of one or more sub-pictures configuring one picture, and a second syntax element indicating whether to process a boundary of the one or more sub-pictures as a boundary of the one picture on the basis of the first syntax element; and the second syntax element is parsed only when the number of the one or more sub-pictures is two or more.

    Abstract: A video signal processing method comprises the steps of: receiving information for prediction of a current block; determining whether or not a merge mode is applied to the current block on the basis of the information for prediction; when a merge mode is applied to the current block, obtaining a first syntax element indicating whether or not a combined prediction is applied to the current block, wherein the combined prediction indicates a prediction mode that combines inter-prediction and intra-prediction; generating an inter-prediction block and an intra-prediction block of the current block when the first syntax element indicates that the combined prediction is applied to the current block; and generating a combined prediction block of the current block by weighted-summing the inter-prediction block and the intra-prediction block.
