Claim 2:
3. A non-transitory computer-readable medium storing computer executable instructions and a bitstream, the bitstream comprising:
buffer descriptions in a sequence parameter set corresponding to buffer descriptions;
reference list descriptions in the sequence parameter set corresponding to reference list descriptions; and
a selecting information in a header of one of slices in one of pictures corresponding to a selecting information,
the computer executable instructions, when executed by a computer, cause the computer to decode the bitstream by performing a decoding method comprising:
obtaining, from the sequence parameter set corresponding to the bitstream,
the buffer descriptions, each of the buffer descriptions specifying reference pictures to be held in a buffer for decoding pictures;
obtaining, from the sequence parameter set, the reference list descriptions, which correspond one-to-one with the buffer descriptions, each of the reference list descriptions indicating a correspondence relationship between one of the reference pictures that is specified by a corresponding one of the buffer descriptions and an index for identifying the one of the reference pictures;
obtaining, from the header of one of slices in one of the pictures, the buffer description selecting information indicating one of the buffer descriptions;
obtaining, from the one of the slices, the index for identifying the one of the reference pictures; and
specifying one of the reference pictures held in the buffer using (i) the reference list description which corresponds to the buffer description indicated by the buffer description selecting information and (ii) the index for identifying the one of the reference pictures.
