Systems and methods for encoding and decoding
Systems and methods for multimedia encoding and decoding are disclosed. The systems and methods include multimedia format detection systems, decoder functionality generation systems, decoder instantiation systems, and multimedia processing engines which are capable of selecting a decoder or playback mechanism for each input encoded multimedia stream. The functionality of the decoder or playback mechanism is represented as syntax elements which may be further encoded. The functionality for decoding or playback is then stored or transmitted with the multimedia bitstream. Alternatively, the functionality and multimedia bitstream can be embedded in or associated with a second digital bitstream. Further, the functionality associated with an encoded multimedia stream can be used to instantiate a decoder or playback mechanism and the encoded multimedia stream decoded with the instantiated decoder or mechanism.
1. A multimedia processing engine comprising:
a format analyzer configured to determine the format of encoded digital data;
a functionality generator in communication with the format analyzer, the functionality generator being configured to select or generate hardware and software platform independent functionality that decodes the digital data encoded in the determined format;
the functionality generator being further configured to generate or select hardware and software platform independent syntax elements that contain information to create and implement a new functionality that decodes the digital data encoded in the determined format in a receiver in which decoding of digital data encoded in the determined format is unsupported; and
a multiplexer configured to multiplex the encoded digital data with the syntax elements and send the multiplexed data and syntax elements to a non-transient storage medium as a single set of bits.
2. The multimedia processing engine of claim 1 , wherein the functionality for decoding the digital data is stored in a library associated with the functionality generator.
3. The multimedia processing engine of claim 1 , wherein the functionality for decoding the digital data is selected from functionality received from a user.
4. The multimedia processing engine of claim 1 , wherein the syntax elements comprise codewords.
5. The multimedia processing engine of claim 1 , further comprising a transmitter configured to transmit the syntax elements to a decoder.
6. A multimedia processing engine comprising:
a demultiplexer configured to demultiplex from a non-transient storage medium a single set of bits encoding digital data and hardware and software platform independent syntax elements sufficient for creating and implementing functionality that decodes the encoded digital data and that is unsupported by the multimedia processing engine prior to receiving the single set of bits;
a functionality interpreter configured to:
receive the syntax elements; and
create and implement the new functionality based on the syntax elements; and
a functionality instantiator configured to generate a decoder based on the created and implemented functionality, wherein the decoder is configured to decode the encoded digital data using the implemented functionality.
7. The multimedia processing engine of claim 6 , wherein the syntax elements comprise codewords.
