Abstract:
An image coding method includes: writing, into a coded bitstream, buffer description defining information for defining a buffer description; constructing a default reference list; reorder pictures included in the default reference list; writing, into the coded bitstream, reference list reordering information for indicating details of the reordering; and coding an image using the buffer description and a reference list resulting from the reordering, and in the reference list reordering information, among the pictures, a picture to be reordered is specified using an index which is used in other processing in the image coding method.

Claim (Index 13):
An image decoding method for decoding a coded bitstream, the image decoding method comprising:\n constructing a first reference list including a plurality of pictures, each of the pictures having a Picture Order Count (POC) assigned thereto and being identified by one of a plurality of reference indexes, the reference indexes corresponding one to one with the pictures included in the first reference list, each of the reference indexes having a different index value, the first reference list being constructed based on the POC assigned to each of the plurality of pictures; obtaining, from the coded bitstream, reference list reordering information for indicating details of reordering to be performed on the first reference list; reordering the pictures included in the first reference list to generate a modified reference list by assigning new reference indexes using the reference indexes, the new reference indexes corresponding one to one with the pictures included in the modified reference list, each of the new reference indexes having a different index value; and decoding a current picture or slice using the new reference indexes and the modified reference list resulting from the reordering, wherein each of the reference indexes (i) identifies one of the pictures included in the first reference picture list such that the reference indexes correspond one to one with the pictures included in the first reference list and (ii) is used in assigning the new reference indexes in the reordering.
