Abstract
A video encoder encodes a plurality of pictures with one of the pictures being a long term reference picture. The encoder provides signaling in a bitstream for a decoder to reconstruct pictures by selectively activating the long term reference picture for use as a reference picture, maintaining the long term reference picture in the buffer while being inactive as a reference picture, changing the long term reference picture from inactive to active as a reference picture, and marking the long term reference picture as being unused for reference so that it is no longer eligible to be used as a reference picture for a subsequent picture and is removed as a reference picture.
