Abstract

Disclosed are a method for decoding a video signal and a device therefor. Specifically, a method for decoding an image on the basis of an inter-prediction mode includes: a step for generating a mergecandidate list by using a spatial merge candidate and a temporal merge candidate of a current block; a step for acquiring a merge index indicating a specific merge candidate from the merge candidate list; and a step for generating a prediction block of the current block by using motion information of the specific merge candidate, wherein the step for generating the merge candidate list may includea step for adding, to the merge candidate list, a first merge candidate indicating a collocated block specified by the motion information of the spatial merge candidate, when a reference picture of the spatial merge candidate is identical to a predetermined picture.

Description

technical field [0001] The present disclosure relates to a still image or moving image processing method, and more particularly, to a method of encoding / decoding a still image or moving image based on an inter prediction mode and an apparatus supporting the method. Background technique [0002] Compression coding means a series of signal processing techniques for transmitting digitized information over communication lines or techniques for storing information in a form suitable for a storage medium. Media including pictures, images, audio, etc. may be targets of compression encoding, and in particular, a technique of performing compression encoding targeting pictures is called video image compression. [0003] Next-generation video content should have the characteristics of high spatial resolution, high frame rate, and high-dimensional scene presentation. In order to process these contents, memory storage, memory access rate and processing power will increase dramatically. ...
