Abstract
An apparatus comprising a first circuit and a second circuit. The first circuit may be configured to generate a control signal in response to a measurement of inter-picture motion between a current picture and a first reference picture. The second circuit may be configured to select the first reference picture or a second reference picture as a better reference picture for motion estimation in response to the control signal.
