Abstract
The disclosed subject matter describes a new pattern description that can be part of an SEI message or a parameter set, and can be used to describe a temporal picture coding structure and associated bitrates and frame rates. The knowledge of the coding structure can benefit transraters, bitstream extractors, and digital video recorders. Decoders can utilize the coding structure information for example, to decode pictures in parallel, using multiple threads/cores.
