Patent Images
1. A method, comprising:
- receiving 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;
determining an adherence of the first and second set of compressed pictures to one or more rules prior to decoding the compressed pictures, the rules comprising the picture interdependency characteristics; and
decoding the first set, the second set, or a combination of both based on an adherence of the first set and the second set to the one or more rules.

13. A method, comprising:
-
providing a video stream comprising a sequence of plural compressed pictures, including a first level and a second level of coded pictures, the first level exhibiting, when decoded, picture interdependencies different than those exhibited by a decoded second level; and providing auxiliary information in the video stream, the auxiliary information conveying that the first level of pictures adheres to a first set of rules and that the second level of coded pictures adheres to a second set of rules; and decoding the first level based on adherence of a first set of rules of the first picture interdependency level and process the second level based on the adherence of a second set of rules corresponding to the second picture interdependency level. - View Dependent Claims (14, 15, 16, 17)
