    Abstract: Provided are methods and apparatuses for encoding and decoding an image. The method of encoding includes: determining a maximum size of a buffer to decode each image frame by a decoder, a number of image frames to be reordered, and latency information of an image frame having a largest difference between an encoding order and a display order from among image frames that form an image sequence, based on an encoding order the image frames that form the image sequence, an encoding order of reference frames referred to by the image frames, a display order of the image frames, and a display order of the reference frames; and adding, to a mandatory sequence parameter set, a first syntax indicating the maximum size of the buffer, a second syntax indicating the number of image frames to be reordered, and a third syntax indicating the latency information.

    Abstract: Provided is a method of decoding an image, the method including: determining at least one coding unit for splitting an image, based on block shape information of a current coding unit; determining at least one transformation unit, based on a shape of the current coding unit included in the at least one coding unit; and decoding the image by performing inverse transformation based on the at least one transformation unit, wherein the block shape information indicates whether the current coding unit is a square shape or a non-square shape. Also, provided is an encoding method corresponding to the decoding method. In addition, provided is an encoding apparatus or decoding apparatus capable of performing the encoding or decoding method.
