Abstract
A method for decoding a video according to the present invention may comprise: deriving a reference sample for a current block, determining an intra prediction mode of the current block, and obtaining a prediction sample for the current block by using the reference sample and the intra prediction mode.
Claims15
A method for decoding a video, the method comprising:
- deriving a reference sample for a current block;
- determining an intra prediction mode of the current block;
- and
- obtaining a prediction sample for the current block by using the reference sample and the intra prediction mode,
- wherein if the intra prediction mode is Planar mode, the prediction sample is generated based on a first prediction sample generated by using at least one of reference samples located on a same horizontal line as a prediction target sample and a second prediction sample generated by using at least one of reference samples located on a same vertical line as the prediction target sample.
