Method and system for controlling a low power mode for external devices
A system and method of entering a low power mode includes an external tuner module having a first external tuner and a receiving device having a first receiving tuner. The receiving device has a controller determining an unused tuner from one of the first external tuner or first receiving tuner and controls entering a low power mode at the unused tuner.
1. A method comprising:
coupling a host device to an external tuner that is separate from and in communication with the host device;
the host device determining the external tuner is streaming data to the host device;
entering a low power mode at the external tuner by control of the host device when the external tuner is not streaming data;
wherein coupling a host device comprises coupling the host device to an external tuner having a first tuner and a second tuner; and
wherein entering a low power mode comprises entering the low power mode for a higher power-using tuner of the first tuner or second tuner.
2. A method as recited in claim 1 wherein determining the external tuner is streaming data to the host device comprises determining whether the first tuner or the second tuner is streaming data to the host device to form an unused tuner and wherein entering a low power mode comprises entering a lower power mode for the unused tuner.
3. A method as recited in claim 1 further comprising entering a low power mode for the first tuner and the second tuner when both the first and second tuners are not streaming data to the host device.
4. A method as recited in claim 1 wherein coupling a host device comprises coupling the host device to an external high definition tuner.
5. A method as recited in claim 1 wherein coupling a host device comprises coupling a receiver to an external tuner.
6. A method as recited in claim 1 wherein coupling a host device comprises coupling a satellite television receiver to an external high definition tuner.
7. A method as recited in claim 1 wherein entering a low power mode comprises entering the low power mode after a predetermined time of not streaming data.
8. A method as recited in claim 1 wherein determining the external tuner is streaming data to the host device comprises generating an unused tuner signal at the host device and wherein entering a low power mode comprises entering the low power mode in response to the unused tuner signal.
