Abstract

Techniques are described related to coding of long term reference pictures for a reference picture set. In some examples a video coder may code candidate long term reference pictures in a parameter set. The video coder also code syntax elements that indicate which long term reference pictures from the candidate long term reference pictures belong in the reference picture set.
