Abstract

A decoder includes circuitry configured to receive a bitstream; store a plurality of long term reference frames in a reference list; retain a long term reference frame in the reference list for a length of time based on a retention time; and decode at least a portion of video using the long term reference frame retained in the reference list. Related apparatus, systems, techniques and articles are also described.
