Video encoding/decoding method and device
摘要
說明書
In a video signal decoding method and device according to the present disclosure, the number of candidate modes belonging to the second candidate group may be m and m may be a natural number such as 1, 2, 3, 4, 5, 6, or more.
In a video signal decoding method and device according to the present disclosure, the second candidate group may not include a default mode included in the first candidate group.
A video signal encoding method and device according to the present disclosure may determine an intra prediction mode of a current block, encode a flag for indicating a candidate group to which an intra prediction mode of the current block belongs and perform intra prediction for the current block based on an intra prediction mode of the current block and a predetermined reference region.
In a video signal encoding method and device according to the present disclosure, the candidate group may include at least one of a first candidate group or a second candidate group, the first candidate group may be configured with a default mode and the second candidate group may be configured by using an intra prediction mode of a neighboring block adjacent to the current block.
In a video signal encoding method and device according to the present disclosure, the default mode may include at least one of a DC mode or a Planar mode.
In a video signal encoding method and device according to the present disclosure, at least one candidate mode belonging to the second candidate group may be derived by adding or subtracting a value of n to or from an intra prediction mode of the neighboring block and n may be a natural number greater than or equal to 2.
