Abstract

Disclosed are a method and an apparatus for coding a video supporting a plurality of layers. The method for coding the video supporting the plurality of layers, according to the present invention, comprises the steps of: inducing a reference layer sample location from a reference layer picture used for inter-layer prediction of a current layer picture; resampling the reference layer picture, based on the reference layer sample location; and generating a prediction sample of a current block by inter-layer predicting the current block of the current layer picture, based on the resampled reference layer picture.

Description

technical field [0001] The present invention relates generally to video compression techniques, and more particularly to methods and apparatus for video encoding supporting multiple layers. Background technique [0002] Recently, demands for high-resolution, high-quality video such as HD (High Definition) video and UHD (Ultra High Definition) video are increasing in various application fields. Because the video data has high-resolution, high-quality images, the amount of data is higher than existing video data. Therefore, when video data is transmitted using a medium such as existing wired and wireless broadband lines or stored in an existing storage medium, transmission costs and storage costs increase. To solve these problems caused by high-resolution, high-quality video data, high-efficiency video compression techniques can be used. [0003] For example, there are the following various techniques as video compression techniques: an inter-frame prediction technique for p...
