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 15):
An image decoding apparatus for decoding a coded bitstream, the image decoding apparatus comprising:\n a processor; and a memory having a computer program stored thereon, the computer program causing the processor to execute operations including:\n constructing a first reference list including a plurality of pictures, each of the pictures having an output order of a frame assigned thereto, each of the pictures being identified by one of a plurality of reference indexes, the reference indexes corresponding one to one with the pictures, each of the reference indexes having a different index value, the first reference list being constructed based on the output order of the frame assigned to each of the plurality of pictures; \n obtaining, from the coded bitstream, reference list reordering information for indicating details of reordering to be performed; \n reordering the pictures to generate a modified reference list including the pictures, the modified reference list being generated by assigning new indexes to the pictures using the reference indexes, the new indexes corresponding one to one with the pictures included in the modified reference list, each of the new indexes having a different index value; and \n decoding a current picture or slice using the new indexes and the modified reference list generated in the reordering, \n 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 indexes in the reordering.
