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

mpm[4] 2 + ((intraPredModeL + 61)%65) mpm[5] 2 + ((intraPredModeL)%65)
(3) When Both intraPredModeL and intraPredModeA are Directional Modes, intraPredModeL is Less than intraPredModeA and a Difference Between intraPredModeL and intraPredModeA is not 1 or 64

The MPM of a current block may include intraPredModeL, intraPredModeA, a default mode, a mode derived by subtracting 1 from intraPredModeA and a mode derived by adding 1 to intraPredModeA. An index may be assigned to the MPM based on a predetermined priority. For example, an index may be assigned to each MPM as in the following Table 4. But, a priority of the present disclosure is not limited to Table 4 and a position of a MPM in a candidate mode list may be different from Table 4.

TABLE 4 mpm[0] intraPredModeL mpm[1] intraPredModeA mpm[2] PLANAR mpm[3] DC mpm[4] 2 + ((intraPredModeA + 62)%65) mpm[5] 2 + ((intraPredModeA ? 1)%65)
