Abstract
The present invention relates to an image coding method and device for buffer management of a decoder and an image decoding method and device. The image coding method according to the present invention: determines the maximum size of a buffer required for decoding each image frame in a decoder and the number of image frames requiring realignment and latency information on an image frame which has the greatest difference between a decoding order and a display order among image frames forming an image sequence based on the decoding order of each image frame of a coded image sequence a decoding order of a reference frame that each image frame refers to the display order of each image frame and a display order of the reference frame; and adds a first syntax representing the maximum size of a buffer a second syntax representing the number of image frames requiring realignment and a third syntax representing latency information to a set of essential sequence parameters that is a set of information related to the coding of an image sequence.
