Abstract
Techniques related to long term reference picture video coding are discussed. Such techniques include determining long term reference pictures for a sequence of pictures, adjusting the quantization parameters for the long term reference pictures based on temporal correlations for pictures temporally neighboring and including the long term reference pictures, and managing reference picture lists including the long term reference pictures.
