METHOD AND APPARATUS FOR PROCESSING VIDEO DATA
Document Type and Number:
WIPO Patent Application WO/2020/130617
Kind Code:
A1
Abstract:
An embodiment of the present specification provides a method and apparatus for processing video data. A method for processing video data, according to an embodiment of the present specification, comprises the steps of: obtaining motion information and bi-directional prediction weight information for inter prediction of a current block; deriving a prediction sample of the current block on the basis of the motion information and the bi-directional prediction weight information; and updating a history-based motion vector predictor (HMVP) candidate list on the basis of HMVP candidates comprising the motion information and the bi-directional prediction weight information, wherein the motion information comprises a first reference index and a first motion vector related to a first reference picture, and a second reference index and a second motion vector related to a second reference picture, and wherein the bi-directional prediction weight information may be used to induce a first weight value applied to a first prediction sample form the first reference picture, and a second weight value applied to a second prediction sample from the second reference picture.
