1. A non-transitory computer readable recoding medium having stored thereon a computer program for coding pictures into a coded bitstream stored thereon, wherein, when executed, the computer program causes a processor to execute operations comprising:
writing, into a sequence header, buffer descriptions that specify reference pictures to be held in a buffer for coding the pictures, the buffer descriptions including long-term information which identifies a reference picture, among a plurality of reference pictures covered by the buffer descriptions, to be assigned as a long-term reference picture;
selecting one of the buffer descriptions for a slice in one of the pictures;
writing, into a header of the slice, selecting information for specifying the selected buffer description; and
coding the slice using the reference picture to be assigned as the long-term reference picture identified by the selected buffer description, wherein the long-term information, which is written into the sequence header includes, (i) a long-term index for identifying the reference picture to be assigned as the long-term reference picture and (ii) a unique picture order count (POC) number for specifying the reference picture identified by the long-term index.
