Computational resource allocation in an information stream decoder

摘要

The invention comprises a method an apparatus for allocating processing resources in an information stream decoder in response to format indicia included within a compressed information stream. Specifically, the invention comprises an apparatus and method for decoding a video stream having an associated source video format to produce a decoded video stream having the same format or a different format, in which a computational resource is allocated in response to a change in format between the associated video format and the resultant video format.
