Abstract

The present invention provides a method of displaying, on a secondary display device, a channel of a mobile television broadcast comprised of multiple channels of content data that was sent to a primary portable mobile communications device. A mobile television broadcast is received by a mobile television receiver in the portable mobile communications device. The user inputs or selects a channel to view on a secondary display device. The mobile television receiver signal processor unpacks the selected channel content data intended for the secondary display device and forwards the data to a secondary short range wireless transceiver within the portable mobile communications device. The selected channel content data is then sent to the secondary display device so that it can be decoded and rendered on the secondary display device.

Claims

1. A portable mobile communications device for receiving a mobile television broadcast and displaying content on a secondary display device comprising:

a mobile television receiver for receiving a mobile television broadcast comprised of multiple channels of content data;

a mobile television signal processor coupled with the mobile television receiver for;

unpacking a mobile television broadcast signal into multiple data streams, one for each channel that was broadcast; and

decoding one of the unpacked data streams so that the data can be rendered on a primary display within the portable mobile communications device;

a portable mobile communications device signal processor for receiving unpacked data streams from the mobile television signal processor; and

a secondary transceiver within the portable mobile communications device coupled with the portable mobile communications device signal processor for transmitting the unpacked data streams to the secondary display device where they can be decoded by and rendered on the secondary display device.

2. The portable mobile communications device of claim 1 wherein the secondary transceiver receives control data from the secondary display device, the control data for establishing a secure wireless communications link between the portable mobile communications device and the secondary display device.

3. The portable mobile communications device of claim 2 wherein the secondary transceiver receives channel selection data from the secondary display device, the channel selection data for identifying the content to be sent from the portable mobile communications device to the secondary display device.

4. The portable mobile communications device of claim 3 wherein the secondary transceiver operates using a short range wireless RF standard.

5. The portable mobile communications device of claim 3 wherein the secondary transceiver operates using a Bluetooth™

wireless standard.

6. The portable mobile communications device of claim 3 wherein the secondary transceiver operates using an 802.11x wireless standard.

7. A method of displaying, on a secondary display device, a channel of a mobile television broadcast comprised of multiple channels of content data that was sent to a primary portable mobile communications device, the method comprising:

in the portable mobile communications device;

receiving the mobile television broadcast via a mobile television receiver;

receiving input identifying a channel to be displayed on a secondary display device;

unpacking the identified channel content data;

sending the unpacked channel content to the secondary display device so that it can be rendered on the secondary display device.

8. The method of claim 7 further comprising receiving control data from the secondary display device, the control data for establishing a secure wireless communications link between the portable mobile communications device and the secondary display device.

9. The method of claim 8 further comprising receiving channel selection data from the secondary display device, the channel selection data for identifying the content to be sent from the portable mobile communications device to the secondary display device.

10. A computer program product for displaying, on a secondary display device, a channel of a mobile television broadcast comprised of multiple channels of content data that was sent to a primary portable mobile communications device, the computer program product comprising:

in the portable mobile communications device;

computer program code for receiving the mobile television broadcast via a mobile television receiver;

computer program code for receiving input identifying a channel to be displayed on a secondary display device;

computer program code for unpacking the identified channel content data;

computer program code for sending the unpacked channel content to the secondary display device so that it can be rendered on the secondary display device.

11. The computer program product of claim 10 further comprising computer program code for receiving control data from the secondary display device, the control data for establishing a secure wireless communications link between the portable mobile communications device and the secondary display device.

12. The computer program product of claim 11 further comprising computer program code for receiving channel selection data from the secondary display device, the channel selection data for identifying the content to be sent from the portable mobile communications device to the secondary display device.
