Abstract: Disclosed herein is a method of decoding an image. The method includes acquiring intra chroma prediction information of a current block from a bitstream, deriving an intra chroma prediction mode of the current block based on the intra chroma prediction information, and performing intra prediction with respect to the current block based on the intra chroma prediction mode. The intra chroma prediction mode may be any one of a linear model (LM)) mode, a derived luma (DM) mode, a Planar mode, a Vertical mode, a Horizontal mode and a DC mode, and a first bit of the intra chroma prediction information may be used to determine whether the intra chroma prediction mode is an LM mode.

Abstract: The present invention relates to an image information decoding method. The decoding method includes receiving a bit stream including a Network Abstraction Layer (NAL) unit that includes information related to encoded image, and parsing a NAL unit header of the NAL unit. The NAL unit header may not include 1 bit flag information that represents whether a picture is a non-reference picture or a reference picture in the entire bit stream during encoding.
