Abstract:
Provided are methods and apparatuses for encoding and decoding an image. 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.

Claim (Index 2):
A method for encoding an image, the method comprising:\n splitting a picture into a plurality of maximum coding units; splitting a maximum coding unit among the plurality of maximum coding units into a plurality of coding units; determining one or more prediction units in a coding unit among the plurality of coding units; and performing motion prediction for a prediction unit among the one or more prediction units using a reference frame; and generating a bitstream including a first syntax indicating a maximum size of a buffer required to decode an image frame by a decoder, a second syntax indicating the number of image frames required to be reordered, a third syntax indicating a latency information, information about a size of the maximum coding unit, and a split information of the coding unit, wherein the first syntax, the second syntax, and the third syntax are added to a mandatory sequence parameter set, wherein the number of image frames required to be reordered is determined based on an encoding order of the image frame, an encoding order of the reference frame referred to by the image frame, a display order of the image frame, and a display order of the reference frame, wherein the latency information indicates a largest difference between the encoding order and the display order, wherein the first syntax is used to determine the maximum size of the buffer storing decoded picture, wherein the second syntax and the third syntax are used to determine whether to output the decoded picture stored in the buffer by increasing a latency parameter count of the decoded picture stored in the buffer by one whenever a picture include in an image sequence is decoded, and the decoded picture is outputted from the buffer when the latency parameter count of the decoded picture is equal to the latency information.
