Abstract: A method and an apparatus of encoding/decoding intra prediction mode using a plurality of candidate intra prediction modes are disclosed. A method of decoding an intra prediction mode can comprise deriving three candidate intra prediction modes about a current block and deriving an intra prediction mode of the current block. Therefore, by predicting an intra prediction mode of the current block based on a plurality of candidate intra prediction modes, video encoding efficiency can be improved.

Abstract translation: 公开了使用多个候选帧内预测模式对帧内预测模式进行编码/解码的方法和装置。 帧内预测模式的解码方法可以包括导出关于当前块的三个候选帧内预测模式并导出当前块的帧内预测模式。 因此，通过基于多个候选帧内预测模式预测当前块的帧内预测模式，可以提高视频编码效率。
