Systems and methods for encoding and decoding

摘要

Systems and methods for encoding and decoding are disclosed. The systems and methods include multimedia decoder instantiation systems and multimedia processing engines which are capable of being upgraded or reconfigured to support a new or previously-unsupported compression format, without the need for platform-specific software or hardware upgrades.

主权项

1. A multimedia processing engine comprising:
a coding decision component comprising: a plurality of functionality evaluator/estimators each receiving one or more functionalities from a functionality input, evaluating the received functionalities for multimedia data based on objective and/or subjective criteria, and creating a value result for each criterion; a comparator which determines an encoding functionality for encoding multimedia data by comparing the value results of the criteria for each functionality and/or the overall measure of each functionality; and which determines a decoding functionality corresponding to the encoding functionality by comparing the value results of the criteria for each functionality and/or the overall measure of each functionality; said multimedia processing engine further comprising: an encoder that encodes the multimedia data using the determined encoding functionality; and a processing unit that prepares the encoded multimedia data and the determined decoding functionality for communication to a decoder, wherein said decoding functionality includes syntax elements for reconfiguring the decoder.
