Abstract
A method and apparatus that determine one or more reference pictures for the current image unit and indicate the reference pictures using information associated with COIs (coding order indexes) of the reference pictures are disclosed. The image unit corresponds to a picture, a slice of the picture, or a region of the picture. Inter-picture encoding or decoding is applied to the input data using the reference pictures. The information associated with the COIs can be incorporated in a slice header or a picture header of a bitstream associated with the video sequence. Furthermore, the COI can be represented by a coded COI using a fixed number of bits, wherein the coded COI is constrained to a range from 0 to MAC_COI-1 and MAX_COI is a positive integer.
