Abstract
A video decoding device decodes from a bitstream an intra-prediction mode of the current block, derives a reference line group of the current block, and derives a reference line from within the reference line group. Further, the video decoding device generates a predictor of the current block by using the reference line according to the intra-prediction mode.
Claims16
A method performed by a video decoding device for intra-predicting a current block, the method comprising:
- decoding, from a bitstream, an intra-prediction mode of the current block;
- deriving a reference line group of the current block, the reference line group comprising at least one reference line;
- deriving a reference line within the reference line group, wherein the reference line in the reference line group is indicated by a reference line candidate index;
- and
- generating a predictor of the current block by using the reference line according to the intra-prediction mode.
A method performed by a video encoding device for intra-predicting a current block, the method comprising:
- determining an intra-prediction mode of the current block;
- deriving a reference line group of the current block, wherein the reference line group comprising at least one reference line;
- deriving a reference line within the reference line group, wherein the reference line in the reference line group is indicated by a reference line candidate index;
- and
- generating a predictor of the current block by using the reference line according to the intra-prediction mode.
A computer-readable recording medium storing a bitstream generated by a video encoding method, the video encoding method comprising:
- determining an intra-prediction mode of a current block;
- deriving a reference line group of the current block, wherein the reference line group comprising at least one reference line;
- deriving a reference line within the reference line group, wherein the reference line in the reference line group is indicated by a reference line candidate index;
- and
- generating a predictor of the current block by using the reference line according to the intra-prediction mode.
