Abstract: A video coder codes a slice header for a slice of video data. The slice header includes a syntax element comprising identifying information for a long term reference picture, wherein the identifying information is explicitly signaled in the slice header or derived from a sequence parameter set corresponding to the slice. When the syntax element indicates that the identifying information for the long term reference picture is explicitly signaled, to code the slice header, the video coder is further configured to code a value for the identifying information for the long term reference picture in the slice header.
