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 1):
An apparatus for encoding an image, the apparatus comprising:\n an encoder for encoding an image frame by performing motion prediction using a reference frame; and an output unit for determining a maximum size of a buffer required to decode the image frame by a decoder and the number of image frame required to be reordered, 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, determining latency information of the image frame having a largest difference between the encoding order and the display order, and generating a bitstream by adding a first syntax indicating the maximum size of the buffer, a second syntax indicating the number of image frames required to be ordered, and a third syntax indicating the latency information to a mandatory sequence parameter set, wherein a maximum size of a buffer storing decoded picture is determined based on the first syntax, wherein, whether to output the decoded picture stored in the buffer is determined based on the second syntax and the third syntax 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, the decoded picture is outputted from the buffer when the latency parameter count of the decoded picture is equal to the latency information.
