Abstract: Systems and methods that receive a video stream comprising a sequence of compressed pictures, the compressed pictures comprising a plurality of levels of picture importance including a first picture level and a second picture level, track the compressed pictures to ascertain which of the compressed pictures correspond to the first level, and responsive to ascertaining which of the compressed pictures correspond to the first level, tracking the compressed pictures to ascertain which of the compressed pictures correspond to the second level.
