Abstract

Embodiments of the present invention provide a system and method for processing coded video data stored on removable storage media. In an exemplary embodiment, the system comprises a system manger configured to receive inputs from a user of the system and, in response to the inputs, to read organizational structure information stored on a removable storage medium. The system manager is further configured to identify a set of coded video data stored on the removable storage medium based on the inputs and the organizational structure information. The system manager is further configured to retrieve instructions from a decoding application stored on the removable storage medium and to transmit the instructions to a processing element configured to receive the instructions transmitted by the system manager. The processing element is configured to execute the instructions, wherein execution of the instructions by the processing element decodes the set of coded video data into decoded video data.

Claims

5. The system of claim 1, wherein said decoding application employs a security feature to prevent unauthorized access of said set of coded video data.

6. The system of claim 1, wherein said set of coded video data defines a plurality of video clips.

7. The system of claim 6, wherein said organizational structure information comprises at least one play list indicating a correspondence between said plurality of video clips.

8. The system of claim 1, further comprising:

a compiler configured to receive said instructions and to translate said instructions into a form compatible with said processing element.

9. The system of claim 8, further comprising:

a second processing element configured to receive instructions from said compiler and dedicated to executing said instructions received from said compiler.

10. The system of claim 1, wherein said coded video data is compressed.

11. The system of claim 1, wherein said coded video data is encrypted.

12. The system of claim 1, further comprising a video output device configured to receive said decoded data and to produce images and sound based on said decoded video data.

13. A system for processing coded video data stored on removable media, comprising:

means for reading organizational structure information stored on a removable storage medium;

means for retrieving a set of coded video data from said medium based on said inputs and said organizational structure information;

means for retrieving a decoding application from said medium; and

means for decoding said set of coded video data via said decoding application to produce decoded video data.

14. The system of claim 13, further comprising means for receiving a removable storage medium.

15. The system of claim 13, further comprising means for receiving inputs from a user interface device.

16. The system of claim 13, further comprising means for producing images and sound based on said uncoded video data.

17. A method for processing coded video data stored on a removable storage medium, comprising:

reading organizational structure information stored on a removable storage medium;

retrieving a set of coded video data from said medium based on said inputs and said organizational structure information;

retrieving a decoding application from said removable storage medium; and

decoding said set of coded video data via said decoding application to produce decoded video data.

18. The method of claim 17, further comprising receiving a removable storage medium.

19. The method of claim 18, wherein said removable storage medium is a digital video disc (DVD).

20. The method of claim 17, further comprising:

determining a location of said decoding application based on said organizational structure information; and

performing said retrieving said decoding application based on said determining step.

21. The method of claim 17, wherein said decoding further comprises employing a security feature to prevent unauthorized access of said set of coded video data.

22. The method of claim 17, further comprising:

analyzing said organizational structure information; and

identifying said set of coded video data based on said analyzing.

23. The method of claim 17, further comprising using said set of coded video data to define a video clip.

24. The method of claim 17, further comprising using said set of coded video data to define a plurality of video clips.

25. The method of claim 22, wherein said analyzing further comprises analyzing at least one play list included within said organizational structure information, said at least one play list indicating a correspondence between said plurality of video clips.

26. The method of claim 17, further comprising:

compiling said decoding application subsequent to said retrieving and prior to said decoding.

27. The method of claim 26, further comprising:

performing said compiling via a processing element dedicated to compiling decoding applications stored on said removable storage media.
