Patent 9787979 was granted and assigned to Vidyo on October, 2017 by the United States Patent and Trademark Office.
Techniques to determine a level id in a layered bitstream are disclosed, such that the same level id can be used for all layers of a scalable bitstream. Also disclosed are techniques to signal level ids for sub bitstreams that can be indicative of lower computational requirements than the level id used for the layered bitstream.
