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 for off-loading Internet Protocol Television (IPTV) media content to an external fixed viewing device, the mobile device comprising:

a mobile interface operable to establish a connection to an IPTV network via a mobile access network;

a network interface operable to establish a connection to the 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 via the mobile interface to receive a decryption key for the IPTV media content and to provide the decryption key to the viewing device via the network interface to enable the viewing device to receive, 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.

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

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

7. The mobile device of claim 1, wherein the processor is further operable to receive from the viewing device display information indicating display capabilities of the viewing device via the network interface and to provide the display information to the IPTV network via the mobile interface.

8. The mobile device of claim 7, wherein the processor is further operable to provide the display information to the IPTV network with a request for the IPTV content via the mobile interface, to receive the IPTV content formatted in accordance with the display information via the mobile interface and to provide the received IPTV content to the viewing device via the network interface.

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

a display device;

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

a processor coupled to the display device and the network interface and operable to receive a decryption key from the mobile device via the network interface, to receive IPTV content from an IPTV network via the network interface and to decrypt the received IPTV content using the decryption key for rendering of the 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 network interface are included within a set top box coupled to the television.

11. The viewing device of claim 9, wherein the processor is further operable to provide display information indicating display capabilities of the display device to the mobile device via the network interface for transmission to the IPTV network and to receive the IPTV content formatted in accordance with the display information for rendering on the display device.

12. The viewing device of claim 11, wherein the processor is further operable to receive the IPTV content from the mobile device via the network interface.

13. The viewing device of claim 9, wherein the network interface is further operable to establish a connection with the IPTV network and the processor is further operable to receive the IPTV content directly from the IPTV network via the network interface.

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

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

15. 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, the viewing device further operable to receive the IPTV content from the IPTV network and to decrypt the received IPTV content using the decryption key for rendering of the decrypted IPTV content thereon.

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

17. The mobile IPTV system of claim 15, wherein the mobile device is further operable to receive from the viewing device display information indicating display capabilities of the viewing device and to provide the display information to the IPTV network.

18. The mobile IPTV system of claim 17, wherein the mobile device is further operable to provide the display information to the IPTV network with a request for the IPTV content, to receive the IPTV content formatted in accordance with the display information from the IPTV network and to provide the received IPTV content to the viewing device.

19. The mobile IPTV system of claim 15, wherein the viewing device is further operable to establish a connection with the IPTV network to receive the IPTV content directly from the IPTV network.

20. 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;

providing the decryption key from the mobile device to an external fixed viewing device; and

enabling IPTV content from the IPTV network to be provided to the viewing device for decryption using the decryption key and rendering thereon.
