Abstract

Secure rights protection for broadcast mobile content techniques are described in which broadcast content may be securely provided to a mobile device. In one or more embodiments, this is accomplished by requesting and issuing of a content license via a data network based upon a subscriber identity module (SIM) of a mobile device. The license may then be utilized by the mobile device to output content received via a broadcast network.

Claims

1. An apparatus comprising:

a processor core;

a subscriber identity module (SIM) maintaining a subscriber identity; and

a module executable via the processor core to;

form a request to be communicated via a wireless data network that includes the subscriber identity obtained from the SIM; and

receive a response to the request that includes a license having the subscriber identity and one or more keys to decrypt content received via a broadcast network.

2. The apparatus as recited in claim 1, wherein the content is broadcast television content.

3. The apparatus as recited in claim 1, wherein the apparatus forms at least a portion of a mobile handset.

4. The apparatus as recited in claim 1, wherein:

the license is sought from a wireless provider; and

the content is provided by a content provider separate from the wireless provider.

5. The apparatus as recited in claim 1, wherein the module is to obtain the content via the broadcast network;

retrieve the one or more keys to decrypt content from the license;

decrypt the content utilizing the one or more keys; and

output the decrypted content.

6. The apparatus as recited in claim 1, wherein the module is to:

compare a subscriber identity of the license with the subscriber identity maintained in the subscriber identity module (SIM); and

selectively decrypt the content based on the comparison.

7. The apparatus as recited in claim 1, wherein the subscriber identity obtained from the subscriber identity module (SIM) is to enable a sender of the request to communicate the request via the wireless network.

8. The apparatus as recited in claim 7, wherein the subscriber identifier obtained from the subscriber identity module (SIM) is to also enable the sender of the request to communicate voice data via the wireless network.

9. A method comprising:

forming at a mobile handset a request for a license to be communicated via a wireless network; and

receiving the license via the wireless network in response to the request, wherein the license configures the mobile handset to output content received over a broadcast network that is separate from the wireless network.

10. The method as recited in claim 9, wherein the content is broadcast television content.

11. The method as recited in claim 9, wherein:

the license is sought from a wireless provider; and

the content is provided by a content provider.

12. The method as recited in claim 11, wherein the wireless provider manages the wireless network and does not manage the broadcast network.

13. The method as recited in claim 9, wherein;

the content is broadcast in encrypted form over the broadcast network; and

the license is to permit decryption of the content.

14. The method as recited in claim 9, wherein:

the request includes a subscriber identity from a subscriber identity module (SIM) of the mobile handset; and

the license received by the mobile handset includes a license subscriber identity to permit a determination whether the license subscriber identity matches the subscriber identity from the subscriber identity module (SIM) of the mobile handset.

15. The method as recited in claim 14, further comprising:

determining if the license subscriber identity in the received license matches the subscriber identity from the subscriber identity module (SIM) of the mobile handset;

when the subscriber identities match, obtaining one or more keys from the license to decrypt the content and outputting the decrypted content via the mobile handset.

16. The method as recited in claim 9, wherein the license is to provide one or more keys to decrypt the content.

17. The method as recited in claim 9, wherein the request includes one key of an encryption key pair corresponding to the mobile handset to permit:

encryption of the license received in response to the request by a recipient of the request; and

decryption of the license using the other key of the encryption key pair by the mobile handset.

18. One or more computer readable media comprising computer executable instructions, which when executed direct a server of a wireless service provider to:

receive a request from a client via a wireless data network that includes a subscriber identity from a subscriber identity module (SIM) of the client; and

form a license in response to the request that includes the subscriber identifier and a key to decrypt broadcast content.

19. One or more computer readable media as recited in claim 18, further comprising instructions, which when executed direct the server to communicate the license via the wireless network to the client providing the request, wherein the license is to configure the client to output the broadcast content.

20. One or more computer readable media as recited in claim 18, wherein the broadcast content is television content provided by a content provider via a broadcast network.

21. One or more computer readable media as recited in claim 18, wherein the subscriber identity from the subscriber identity module (SIM) is to enable the client providing the request to communicate the request via the wireless data network.

22. One or more computer readable media as recited in claim 21, wherein the subscriber identity from the subscriber identity module (SIM) is to also enable the client providing the request to communicate voice data via the wireless data network.

23. An apparatus comprising:

a processor core;

a liquid crystal display (LCD) device; and

a module executable via the processor core to;

receive a license via a wireless data network;

receive encrypted television content via a broadcast network; and

utilize the license to decrypt the encrypted television content for display on the display device.

24. The apparatus as recited in claim 23, wherein the license is to provide:

a subscriber identity to verify the identity of a receiving device; and

one or more keys configured to permit the decryption of the encrypted television content.

25. The apparatus as recited in claim 23, further comprising a subscriber identity module (SIM), wherein the SIM provides a subscriber identity to enable a sender of the request to obtain data including the license via the wireless data network.

26. The apparatus as recited in claim 25 further comprising one or more antennas operable to provide connections to the wireless data network and the broadcast network, wherein the SIM is to enable the one or more antennas to receive voice data service which is provided by a service provider via the wireless data network.
