Title:
METHOD AND DEVICE FOR STORING MOTION VECTOR FOR INTRA PREDICTION BLOCK
Document Type and Number:
WIPO Patent Application WO/2023/219301
Kind Code:
A1
Abstract:
A method and device for storing a motion vector for an intra prediction block are disclosed. In the present embodiment, an image decoding device generates a prediction block of a current block according to intra prediction by using reconstructed neighboring samples, or generates a block prediction block and motion information of the current block on the basis of inter prediction which uses reconstructed pictures, a reconstructed motion vector field, and neighboring motion information. The video decoding device stores motion information corresponding to the position of a current block in a motion vector field of the current block on the basis of a prediction mode according to intra prediction or motion information according to inter prediction, position information of the current block, and size information of the current block.
