Abstract

A system and method for using a controllable appliance to report an inoperable state of a controlling device. The appliance is caused to repeatedly determine, at a first predetermined timed interval, if a wireless notification signal, repeatedly transmitted by the controlling device at a second predetermined timed interval, has been received from the controlling device. When the wireless notification signal has not been received from the controlling device within the first predetermined timed interval, the appliance is caused to issue a status notification that the controlling device is in an inoperable state.

Claims

1. A method for using a controllable appliance to determine an inoperable state of a controlling device, the method comprising:

using a timer of the controllable appliance to measure a first plurality of timed intervals each having a first predetermined duration;

causing the controllable appliance to determine if a wireless notification signal has been received from the controlling device during each of the first plurality of timed intervals; and

when the wireless notification signal has not been received from the controlling device during at least one of the first plurality of timed intervals, causing the controllable appliance to issue a status notification that the controlling device is in an inoperable state.

2. The method as recited in claim 1, wherein the controllable appliance comprises a set top box and wherein the method comprises causing the set top box to issue the status notification that the controlling device is in an inoperable state to a headend server in communication with the set top box.

3. The method as recited in claim 1, comprising causing the controllable appliance to restart a measuring of the first plurality of timed intervals in response to the controllable appliance receiving any wireless signal from the controlling device.

4. The method as recited in claim 1, comprising using a timer of the controlling device to measure a second plurality of timed intervals each having a second predetermined duration and causing the controlling device to transmit the wireless notification signal at an expiration of each of the second plurality of timed intervals, wherein the first predetermined duration of each of the first plurality of timed intervals is longer than the second predetermined duration of each of the second plurality of timed intervals.

5. The method as recited in claim 1, wherein the wireless notification signal comprises data indicative of a battery state for the controlling device and, when the data in the wireless notification signal is indicative of a low or no power battery state for the controlling device, causing the controllable appliance to issue a status notification that the controlling device is in a bad battery state.

6. The method as recited in claim 5, wherein the controllable appliance comprises a set top box and wherein the method comprises causing the set top box to issue the status notification that the controlling device is in a bad battery state to a headend server in communication with the set top box.

7. The method as recited in claim 1, wherein the wireless notification signal comprises data indicative of an error state for the controlling device and, when the data in the wireless notification signal is indicative of an error having occurred in the controlling device, causing the controllable appliance to issue a status notification that the controlling device is in an error state.

8. The method as recited in claim 7, wherein the controllable appliance comprises a set top box and wherein the method comprises causing the set top box to issue the status notification that the controlling device is in an error state to a headend server in communication with the set top box.

9. A system, comprising:

a controllable appliance having a first timer, wherein the first timer is used to measure a first plurality of timed intervals each having a first predetermined duration; and

a controlling device having a second timer, wherein the second timer is used to measure a second plurality of timed intervals each having a second predetermined duration, and code data for use in controlling functional operations of the controllable appliance;

wherein the controlling device transmits to the controllable appliance a wireless notification signal at an expiration of each of the second plurality of timed intervals and wherein the controllable appliance determines if the wireless notification signal has been received from the controlling device during each of the first plurality of timed intervals and, when the wireless notification signal has not been received from the controlling device during at least one of the first plurality of timed intervals, the controllable appliance is caused to issue a status notification that the controlling device is in an inoperable state.

10. The system as recited in claim 9, wherein the controllable appliance comprises a set top box and wherein the set top box is caused to issue the status notification that the controlling device is in an inoperable state to a headend server in communication with the set top box.

11. The system as recited in claim 9, wherein the controllable appliance is caused to restart a measuring of the first plurality of timed intervals in response to the controllable appliance receiving any wireless signal from the controlling device.

12. The system as recited in claim 9, wherein the first predetermined duration is longer than the second predetermined duration.

13. The system as recited in claim 9, wherein the wireless notification signal comprises data indicative of a battery state for the controlling device and, when the data in the wireless notification signal is indicative of a low or no power battery state for the controlling device, the controllable appliance is caused to issue a status notification that the controlling device is in a bad battery state.

14. The system as recited in claim 13, wherein the controllable appliance comprises a set top box and wherein the set top box is caused to issue the status notification that the controlling device is in a bad battery state to a headend server in communication with the set top box.
