IMAGE INFORMATION DECODING METHOD, IMAGE DECODING METHOD, AND DEVICE USING SAME

摘要

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 an 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.
