Abstract

A system for transferring verified media data. The system comprising: an item of content storing the media data, and having an associated serial number; a computing device including a first storage device and a network interface; a secure copying application program; a secure copy of the media data generated by the secure copying application program and stored on the first storage device; a verification server including a serial number database and having a network connection to the computing device through the network interface, wherein the secure copying application program generates the secure copy after verifying the serial number is valid and active by communicating with the verification server; and a portable copy of the media data, including license information, generated from the secure copy by the secure copying application program.

Claims

1. A system for transferring verified media data stored in an item of content having an associated serial number, the system comprising:

a computing device including a first storage device and a network interface;

a secure copying application program;

a secure copy of said media data generated by said secure copying application program and stored on said first storage device;

a verification server including a serial number database and having a network connection to said computing device through said network interface,

wherein said secure copying application program generates said secure copy after verifying said serial number is valid and active by communicating with said verification server; and

a portable copy of said media data including license information of said media data, said portable copy generated from said secure copy by said secure copying application program.

2. The system of claim 1, wherein said portable copy is stored on a tangible portable recording medium.

3. The system of claim 1, wherein said item of content includes a digital video disk (DVD).

4. The system of claim 1, wherein said associated serial number is embedded in said media data.

5. The system of claim 1, wherein said associated serial number is attached to the package of said item of content.

6. The system of claim 1, wherein said media data includes a movie.

7. The system of claim 1, wherein said license information further indicates limitations on the use of said portable copy.

8. The system of claim 1, wherein said secure copying application program is stored in said first storage device of said computing device.

9. The system of claim 1, wherein said secure copying application program is provided by digital rights management (DRM) of a media player on the computing device.

10. The system of claim 1, further comprising

a portable media player device including a second storage device and a license management application program stored in said second storage device, said license management application program configured to process and control access to said media data on said portable copy according to said license information.

11. The system of claim 10, wherein said portable copy is stored on said second storage device.

12. The system of claim 10, wherein said secure copying application program is stored in said second storage device of said portable media player device.

13. The system of claim 10, wherein said secure copying application program is provided by digital rights management (DRM) of a media player on the portable media player device.

14. The system of claim 10, wherein said portable media player includes a laptop computer.

15. The system of claim 10, wherein said portable media player includes an MP3 player.

16. A method for transferring verified media data, the method comprising:

receiving said media data on an item of content into a computing device;

receiving a serial number associated with said item of content;

requesting verification of said serial number;

receiving a confirmation of said verification indicating that said serial number is valid and active;

generating a secure copy of said media data;

generating a portable copy of said media data from said secure copy, said portable copy including license information of said media data; and

storing said portable copy in a portable media player device.

17. The method of claim 16, further comprising

embedding said serial number in said media data.

18. The method of claim 16, wherein said media data includes a movie.

19. The method of claim 18, further comprising

processing said portable copy in said portable media player device according to said license information.

20. The method of claim 19, wherein said portable media player device includes a DVD player.

21. The method of claim 20, wherein processing said portable copy includes playing the movie on said DVD player.

22. The method of claim 19, wherein processing said portable copy includes processing said media data according to said license information.

23. The method of claim 22, wherein processing said media data includes playing the movie according to limitations set forth in said license information.

24. The method of claim 23, wherein said limitations include an expiration period after which said portable media player device will not play the movie.

25. A computer program, stored on a tangible storage medium, for use in transferring verified media data, the program comprising executable instructions that cause a computer to:

receive said media data on an item of content into a computing device;

receive a serial number associated with said item of content;

request verification of said serial number;

receive a confirmation of said verification indicating that said serial number is valid and active;

generate a secure copy of said media data; and

generate a portable copy of said media data from said secure copy, said portable copy including license information of said media data,

wherein said portable copy is transferred to a portable media player device so that the portable media player device can process said portable copy according to said license information.

26. A system for transferring verified media data, the method comprising:

means for receiving said media data on an item of content into a computing device;

means for receiving a serial number associated with said item of content;

means for requesting verification of said serial number;

means for receiving a confirmation of said verification indicating that said serial number is valid and active;

means for generating a secure copy of said media data;

means for generating a portable copy of said media data from said secure copy, said portable copy including license information of said media data; and

means for storing said portable copy in a portable media player device.

27. The system of claim 26, further comprising

means for processing said portable copy in said portable media player device according to said license information.
