Title:
IMAGE ENCODING/DECODING METHOD AND DEVICE, AND RECORDING MEDIUM STORING BITSTREAM
Document Type and Number:
WIPO Patent Application WO/2020/060316
Kind Code:
A1
Abstract:
An image encoding method is disclosed in the present specification. An image decoding method according to the present invention can comprise the steps of: deciding the location of a co-located block in a co-located picture for a current block; deciding a representative motion vector of the current block by means of motion information in the location of the co-located block; and deriving motion information for a sub-block comprised in the current block by means of the representative motion vector.
