Abstract: The disclosure discloses a method for processing a video signal and an apparatus therefor. Specifically, the method of processing a video signal based on an inter prediction, comprising: configuring a merge list based on a neighboring block of a current block; adding a history based merge candidate included in a history based merge candidate list to the merge list when a number of a merge candidate included in the merge list is smaller than a first predetermined number; obtaining a merge index indicating a merge candidate used for an inter prediction of the current block within the merge list; and generating a prediction block of the current block based on motion information of a merge candidate indicated by the merge index, wherein a step of adding the history based merge candidate to the merge list comprises checking whether a second predetermined number of the history based merge candidate within the history based merge candidate list has the same motion information as the merge candidate included in the merge list.

Abstract: The disclosure discloses a method for processing video signals and an apparatus therefor. Specifically, the method of processing video signals based on history based motion vector prediction, comprising: configuring a merge candidate list based on a neighboring block to a current block; adding a history based merge candidate of the current block to the merge candidate list when a number of merge candidates included in the merge candidate list is smaller than a first predetermined number; adding a zero motion vector to the merge candidate list when the number of merge candidates included in the merge candidate list is smaller than a second predetermined number; obtaining a merge index indicating a merge candidate used for inter prediction of the current block in the merge candidate list; generating a prediction sample of the current block based on motion information of the merge candidate indicated by the merge index; and updating a history based merge candidate list based on the motion information.

Abstract: A method of processing a video signal based on inter prediction includes constructing a first merge candidate list of a current block using a spatial merge candidate and temporal merge candidate of the current block, constructing a second merge candidate list by adding a history-based merge candidate indicating motion information of a block coded prior to the current block to the first merge candidate list, obtaining a merge index indicating a merge candidate applied to the current block within the second merge candidate list, and generating a prediction block of the current block using motion information of a merge candidate indicated by the merge index. The history-based merge candidate may be added to the first merge candidate list if the history-based merge candidate has motion information not overlapping motion information of a pre-defined merge candidate among merge candidates included in the first merge candidate list.
