摘要

A video encoding/decoding device according to the present invention may determine an intra prediction mode of a current block on the basis of a most probable mode (MPM) of the current block or an intra prediction mode of a neighboring block, determine a reference region for intra prediction of the current block, and perform intra prediction on the current block by using the intra prediction mode and the reference region.

說明書

6-bits {open oversize bracket} 53 7 60 111100 50?custom character 54 7 61 111101 55 7 62 111110 56 7 63 111111

Alternatively, when the number of a second candidate group is 5, the number of a third candidate group is 56. In a third candidate group, an intra prediction mode having an index of 0?7 may be encoded with 5 bits and an intra prediction mode having an index of 8?55 may be encoded with 6 bits.
