Abstract

A mobile IPTV system enables authenticating and off-loading of IPTV operations from a mobile device to an external fixed viewing device. The mobile device performs authentication to an IPTV network to receive decryption key(s) for use in decrypting IPTV content and provides the decryption key to the viewing device. The viewing device uses the decryption key to decrypt and render IPTV content thereon.

Claims

1. A mobile device comprising:

a mobile interface operable to establish a connection to an Internet Protocol Television (IPTV) network via a mobile access network;

a network interface operable to establish a connection to an external fixed viewing device; and

a processor coupled to the mobile interface and the network interface and operable to authenticate the mobile device to the IPTV network and receive a decryption key for decrypting IPTV content via the mobile interface, the processor being further operable to provide the decryption key and an identifier associated with the mobile device to the viewing device via the network interface, the viewing device using the identifier to emulate the mobile device in order to access the IPTV network independent of the mobile device and request and receive the IPTV content as the mobile device, the viewing device further using the decryption key to decrypt and render the IPTV content thereon.

2. The mobile device of claim 1, further comprising:

a transceiver coupled to the mobile interface to transmit and receive data to and from the mobile access network.

3. The mobile device of claim 2, wherein the transceiver is further coupled to the network interface to transmit and receive data to and from the viewing device.

4. The mobile device of claim 1, further comprising:

a network port coupled to the network interface to provide a physical connection to the viewing device.

5. The mobile device of claim 1, further comprising:

a security token containing authentication information for use in authenticating the mobile device, wherein the processor is further operable to transmit the authentication information to the IPTV network to authenticate the mobile device.

7. The mobile device of claim 1, wherein the identifier includes an identity of the mobile device.

8. The mobile device of claim 1, wherein the identifier includes a temporary identifier associated with the mobile device and assigned to the fixed viewing device by the IPTV network.

6. The mobile device of Clam 5, further comprising:

a memory maintaining the security token and coupled to the processor.

9. A fixed viewing device for rendering IPTV content, comprising:

a display device;

a first network interface operable to establish a connection to a mobile device;

a second network interface operable to establish a connection to an IPTV network; and

a processor coupled to the display device and the first and second network interfaces and operable to receive from the mobile device, via the first network interface, a decryption key and an identifier associated with the mobile device, the processor being further operable to use the identifier to emulate the mobile device in order to access the IPTV network independent of the mobile device via the second network interface and request and receive IPTV content from the IPTV network as the mobile device via the second network interface, the processor further operable to decrypt the received IPTV content using the decryption key for rendering of decrypted IPTV content on the display device.

10. The viewing device of claim 9, wherein the display device includes a television and the processor and the first and second network interfaces are included within a set top box coupled to the television.

11. The viewing device of claim 9, further comprising:

a transceiver coupled to the first network interface to wirelessly transmit and receive data to and from the mobile device.

12. The fixed viewing device of claim 9, wherein the identifier includes an identity of the mobile device.

13. The fixed viewing device of claim 9, wherein the identifier includes a temporary identifier associated with the mobile device and assigned to the fixed viewing device by the IPTV network.

14. A mobile IPTV system for authenticating and off-loading mobile IPTV operations, the mobile IPTV system comprising:

a mobile device operable to establish a connection to an IPTV network via a mobile access network to authenticate the mobile device to the IPTV network to receive a decryption key for use in decrypting IPTV content; and

a fixed viewing device external to the mobile device and operable to establish a connection to the mobile device to receive the decryption key and an identifier associated with the mobile device, the viewing device further operable to use the identifier to emulate the mobile device in order to access the IPTV network independent of the mobile device and request and receive the IPTV content from the IPTV network as the mobile device, the viewing device further operable to decrypt the received IPTV content using the decryption key for rendering of the decrypted IPTV content thereon.

15. The mobile IPTV system of claim 14, wherein the mobile device includes a security token containing authentication information for use in authenticating the mobile device to the IPTV network.

16. The mobile IPTV system of claim 14, wherein the identifier includes an identity of the mobile device.

17. The mobile IPTV system of claim 14, wherein the identifier includes a temporary identifier associated with the mobile device and assigned to the fixed viewing device by the IPTV network.

18. A method for authenticating and off-loading mobile IPTV operations, comprising:

authenticating a mobile device to an IPTV network;

receiving a decryption key at the mobile device from the IPTV network; and

providing the decryption key and an identifier associated with the mobile device from the mobile device to an external fixed viewing device to enable the viewing device to use the identifier to emulate the mobile device in order to access the IPTV network independent of the mobile device and request and receive IPTV content from the IPTV network as the mobile device, the viewing device further using the decryption key to decrypt the IPTV content and render the IPTV content thereon.

19. The method of claim 18, wherein the identifier includes an identity of the mobile device.

20. The method of claim 18, wherein the identifier includes a temporary identifier associated with the mobile device and assigned to the fixed viewing device by the IPTV network.
