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

Alternatively, a decoding device may generate one list by combining a candidate mode list and a first group of the non-MPM. The generated list may be configured with intra prediction modes including the MPM and the second candidate group and may be rearranged in an ascending order. A rearranged intra prediction mode may be compared with remaining mode information. As a result of the comparison, when remaining mode information is greater than or equal to a rearranged intra prediction mode, a process which adds 1 to remaining mode information may be performed. The process may be sequentially performed for each of rearranged intra prediction modes. A decoding device may set a mode value obtained through the process as an intra prediction mode of a current block.

FIG. 7 relates to a method in which remaining mode information is encoded/decoded based on rearrangement of a second candidate group as an embodiment to which the present disclosure is applied.

An encoding device may encode remaining mode information based on remaining modes (non-MPM) other than MPM among the predefined intra prediction modes. An encoding device may rearrange a second candidate group of the non-MPM list at a predetermined position and encode remaining mode information based on a rearranged non-MPM list. The position may be a pre-promised position in an encoding/decoding device.

In reference to FIG. 7, a second candidate group may be rearranged to be positioned behind a third candidate group. Through it, an intra prediction mode corresponding to a second candidate group may be encoded with a codeword which is longer than a third candidate group.
