Abstract

Disclosed is a system and method of bundling full or partial decoding and/or post-processing mechanisms together with media content in the form of an electronic file. The combined file may be transmitted to another device that is able to execute the decoding and/or post-processing such that the receiving device can render the media content in an appropriate manner (e.g., playback of audio, display a picture, etc.) with sufficient fidelity. Aspects of the present invention extend the use of metadata associated with the a multimedia content to incorporate a specification for how the multimedia file should be decoded or partially decoded from a compressed state (e.g., MP3, JPEG, WAV, etc.) and post-processed into a state than can be rendered by a device. In one embodiment, the specification is in the form of a script comprising an ordered list of functions or primitives that are executed by the receiving device to transform the associated multimedia file into the desired content to be rendered. In another embodiment, the decoding instructions are provided as an element of an extensible markup language (XML) file. The XML file may accompany the multimedia file or the multimedia file may be another element of the XML file.

Claims

1. A method for receiving multimedia content by an electronic device, the method comprising:

receiving multimedia content from an associated source;

determining that the multimedia content includes a command component and a media component expressed in a first format.

2. The method of claim 1, wherein the electronic device is a mobile communications device.

3. The method of claim 1, further comprising storing the media component in the first format in a non-volatile memory of the electronic device.

4. The method of claim 1 further comprising processing the command component in the electronic device to transform the media component from the first format to a second format.

5. The method of claim 4 further comprising storing the media component in the second format in a non-volatile memory of the electronic device.

6. The method of claim 4 further comprising rendering the media component in the second format on the electronic device or outputting the media component in the second format by the electronic device to a second electronic device.

7. The method of claim 4, wherein the command component is a script file comprising at least one command specifying a processing step for transforming the media component from the first format to the second format.

8. The method of claim 7, wherein code representing an implementation of at least one element of a command is contained in the script file.

9. The method of claim 7, wherein the script file is in an Extensible Markup Language (XML) compatible format.

10. The method of claim 9, wherein the step of determining that the multimedia content includes a command component and a media component expressed in a first format comprises:

extracting a sequence of one or more commands from the script file using an Extensible Markup Language (XML) parser;

applying a command translator to translate the sequence of commands extracted from the script file into a sequence of one or more elements that can be interpreted by a multimedia framework in the electronic device.

11. The method of claim 10, further including providing code included in the script file to an element plug-in receptacle of the multimedia framework if the script file includes code representing an implementation of at least one of the sequence of elements.

12. The method of claim 11, wherein the step of processing the command component further comprises the multimedia framework interpreting the sequence of one or more elements as a sequence of operations transforming the media component from the first format to the second format.

13. The method of claim 11, wherein the step of processing the command component further comprises the multimedia framework interpreting the sequence of one or more elements as a sequence of operations transforming the media component from the first format to the second format.

14. The method of claim 11 further including java-compatible code in the script file to an element plug-in receptacle of the multimedia framework for processing by a java parser and/or a java codec command translator for transforming the media component from first format to the second format.

15. A method for transmitting multimedia content, the method comprising:

transmitting a request for multimedia content from an electronic device to an associated source, wherein the request includes device dependent configuration information for rendering the multimedia content on the electronic device;

receiving multimedia content from the associated source, wherein the multimedia content includes a command component and a media component expressed in a first format based at least in part on the device dependent configuration information provided in the request.

16. The method of claim 15, wherein the electronic device is a mobile communications device.

17. The method of claim 15, wherein the command component includes computer code to update the device dependent configuration information stored on the electronic device.

18. The method of claim 15 further comprising processing the command component in the electronic device to transform the media component from the first format to a second format.

19. The method of claim 15 further including determining that the multimedia content includes a command component and a media component expressed in a first format by:

extracting a sequence of one or more commands from a script file in the command component using an Extensible Markup Language (XML) parser;

applying a command translator to translate the sequence of commands extracted from the script file into a sequence of one or more elements that can be interpreted by a multimedia framework in the electronic device.

20. A portable communications device comprising:

a non-volatile memory;

a multimedia stack having a plurality of multimedia codecs for processing multimedia content stored in the non-volatile memory,

a processor operable to determine if multimedia content received by the mobile telephone includes a command component and a media component and processing the command component of the multimedia content in the portable communications device to transform the media component from a first format to a second format suitable for rendering on the portable communications device.
