    Abstract: A video decoding method performed by a video decoding device according to the present document may comprise the steps of: parsing, from a bitstream, number information relating to the number of slices each having an explicitly signaled height in a tile of a current picture; on the basis of the number information, parsing, from the bitstream, height information relating to heights of the slices each having an explicitly signaled height; when a value of the number information is n, deriving heights of 0-th to (n-1)-th slices in the tile on the basis of the height information; deriving the height of the n-th slice in the tile on the basis of the height of the (n-1)-th slice; deriving a height of a last slice in the tile on the basis of a height remaining after subtracting the sum of heights of the other slices in the tile from a height of the tile; deriving the number of slices in the tile; and decoding the current picture on the basis of slices of the current picture.

    Abstract: According to an embodiment of the present specification, provided is a method and device for decoding a video signal by means of inter prediction. A method for processing a video signal according to an embodiment of the present specification includes a step for forming a reference picture list of the current picture in a video signal, and a step for performing a prediction with respect to the current picture by using the reference picture list, wherein the step for forming the reference picture list includes: a step for acquiring a picture order count (POC) difference between a picture related to a first entry and another picture, when the first entry of the reference picture list corresponds to a short-term reference picture (STRP) entry; and a step for acquiring a POC modulo value of a picture related to a second entry of the reference picture list, when the second entry corresponds to a long-term reference picture (LTRP) entry. A reference picture list for identifying a picture simply and effectively can be generated to increase compression performance and reduce calculation time.

    Abstract: La presente invención se refiere a un método para procesar una señal de video y un aparato del mismo. Específicamente, un método para procesar una señal de video basada en inter predicción incluye construir una primera lista de candidato de fusión de un bloque actual usando un candidato de fusión espacial y candidato de fusión temporal del bloque actual, construir una segunda lista de candidato de fusión agregando un candidato de fusión a base de historial indicando información de movimiento de un bloque codificado previo al bloque actual a la lista del primer candidato de fusión, obtener un índice de fusión que indica un candidato de fusión aplicado al bloque actual dentro de la segunda lista de candidato de fusión, y generar un bloque de predicción del bloque actual usando información de movimiento de un candidato de fusión indicada por el índice de fusión. El candidato de fusión a base de historial puede ser agregado a la lista del primer candidato de fusión si el candidato de fusión a base de historial tiene información de movimiento que no se sobrepone con la información de movimiento de un candidato de fusión pre-definido entre los candidatos de fusión incluidos en la lista del primer candidato de fusión.
