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.

Tracking and determining pictures in successive interdependency levels

Inferential processing to ascertain plural levels of picture interdependencies

Systems and methods that receive a video stream comprising a sequence of plural compressed pictures, wherein the plural compressed pictures comprises a plurality of sets of compressed pictures, wherein each set in the plurality of sets has a respective picture interdependency characteristic, wherein the compressed pictures in the first set depend for decoding only on pictures from the first set.

Video processing with tiered interdependencies of pictures

Systems and methods that provide a video stream, the video stream comprising a sequence of plural compressed pictures corresponding to a video program, the plural compressed pictures having plural sets of compressed pictures, each of the plural sets adhering to one or more picture interdependencies, properties, or a combination of the picture interdependencies and properties, and provide auxiliary information in the video stream, the auxiliary information comprising plural data fields, the plural data fields comprising a first data field corresponding to one of multiple possible coding scheme, the coding scheme comprising a set of tiers that uniquely define the one coding scheme, the plural data fields further comprising a second data field different from the first data field, the second data field comprising an indication of whether the one or more picture interdependencies, properties, or a combination of both corresponding to the set of tiers is valid for use in decoding.
