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(shuō)明書(shū)

In reference to FIG. 6, when the number of a second candidate group is 4, the number of a third candidate group is 57. In a third candidate group, an intra prediction mode having an index of 0?6 may be encoded with 5 bits and an intra prediction mode having an index of 7?56 may be encoded with 6 bits.
