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 method to generate portable copies of media data stored in an item of content using a computing device, the method comprising:

receiving, by the computing device, the item of content including the media data and a serial number associated with the media data at the computing device, wherein the serial number is embedded in the media data;

extracting, by the computing device, the embedded serial number from the media data by the computing device and verifying with a verification server that the extracted serial number is valid and active;

based on the verification of the serial number being active and valid by the verification server, generating a secure copy of the media data using a secure copying application program stored on the computing device;

identifying, by the computing device, license information associated with the verified serial number;

storing, by the computing device, the secured copy of the media data and the identified license information for the media data in a first storage device;

generating, by the computing device, at least one portable copy of the media data from the stored secured copy by including the identified license information in the at least one portable copy of the media data; and

storing the at least one portable copy on a media player device.

2. The method of claim 1, wherein each of the at least one portable copy is stored on a tangible portable recording medium.

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

4. The method of claim 1, wherein said license information includes limitations on the use of each portable copy.

5. The method of claim 4, wherein the limitations are modified for the least one portable copy made after a certain number of portable copies.

6. The method of claim 4, further comprising

storing said at least one portable copy onto a portable media device,

wherein the limitations are reset by connecting the portable media device to the computing device.

7. The method of claim 1, wherein said secure copying application program is stored in a first storage device of said computing device.

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

9. The method 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 each portable copy according to said license information.

10. The method of claim 9, wherein said each portable copy is stored on said second storage device.

11. The method of claim 9, wherein said secure copying application program is stored in said second storage device of said portable media player device.

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

13. The method of claim 9, wherein said portable media player includes a laptop computer.

14. The method of claim 9, wherein said portable media player includes an MP3 player.

15. A method to transfer media data using a computing device, the method comprising:

receiving, by the computing device, said media data and a serial number associated with and embedded in the media data stored on an item of content into the computing device, wherein the serial number is extracted from said media data;

extracting, by the computing device, the embedded serial number from the media data by the computing device and verifying with a verification server that the extracted serial number is valid and active;

based on the verification of the serial number being active and valid by the verification server, generating a secure copy of the media data using a secure copying application program stored on the computing device;

identifying, by the computing device, license information associated with the verified serial number;

storing, by the computing device, the secured copy of the media data and the identified license information for the media data in a first storage device;

generating, by the computing device, a portable copy of the media data from the stored secured copy by including the identified license information in the portable copy of the media data; and

storing the portable copy in a portable media player device.

16. The method of claim 15, wherein said license information includes limitations on the use of the portable copy.

17. The method of claim 15, wherein the limitations are modified for the portable copy made after a certain number of portable copies, and

wherein the limitations are reset by connecting the portable media player device to the computing device.

18. The method of claim 15, further comprising

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

wherein said portable media player device includes a DVD player.

19. The method of claim 18, wherein processing the portable copy includes playing the movie on said DVD player.

20. The method of claim 18, wherein processing the portable copy includes processing said media data according to said license information.

21. The method of claim 20, wherein processing said media data includes playing the movie according to limitations set forth in said license information.

22. The method of claim 21, wherein said limitations include an expiration period after which said portable media player device will not play the movie.

23. A non-transitory tangible storage medium storing a computer program, to transfer media data, the computer program comprising executable instructions that cause a computer to perform the steps of:

receiving the item of content including the media data and a serial number associated with the media data at the computing device, wherein the serial number is embedded in the media data;

extracting the embedded serial number from the media data by the computing device and verifying with a verification server that the extracted serial number is valid and active;

based on the verification of the serial number being active and valid by the verification server, generating a secure copy of the media data using a secure copying application program stored on the computing device;

identifying license information associated with the verified serial number;

storing the secured copy of the media data and the identified license information for the media data in a first storage device;

generating a portable copy of said media data from said stored secured copy by including the identified license information in the portable copy of said media data; and

storing the portable copy on a media player device.
