Abstract

Disclosed herein are system, method, and computer program product embodiments for synchronizing a state change at a universal remote control. An embodiment operates by sending a state change of the universal remote control to a remote-controlled device. The universal remote control then receives a confirmation message from the remote-controlled device. The universal remote control then updates a state configuration for the remote-controlled device in the universal remote control based on the sent state change. Because the universal remote control exchanges state change information with the remote-controlled device, the universal remote control does not become out of synchronization with the remote-controlled device which minimizes synchronization time and reduces user experience frustration.

First claim

What is claimed is:

1. A computer implemented method for maintaining state synchronization for a universal remote control, comprising:
generating a first device command at the universal remote control to control a remote-controlled device based at least in part on a user input;
sending, via a first communications link, the first device command to the remote-controlled device for performance by the remote-controlled device;
sending, via a second communications link, a state change to the remote-controlled device based at least in part on the sending the first device command, wherein the state change represents a resulting state of the remote-controlled device after performance of the first device command;
receiving, via the second communications link, a confirmation message at the universal remote control from the remote-controlled device in response to the sending the state change;
programming the universal remote control based at least in part on the received confirmation message; and
sending, via the first communications link, a second device command for controlling the remote-controlled device based at least in part on the programming.

2. The method of claim 1 , wherein the second communications link is a bidirectional communication link that uses a radio frequency signal.

3. The method of claim 1 , wherein the first communications link is a unidirectional communication link that uses an infrared signal.

4. The method of claim 1 , the programming further comprising:
updating, at the universal remote, a state configuration for the remote-controlled device based at least in part on the sent state change.

5. The method of claim 1 , wherein the universal remote control is programmed to send the second device command via the first communications link based at least in part on a command set for the remote-controlled device.

6. The method of claim 1 , wherein the remote-controlled device is a television or set top box.

7. The method of claim 1 , further comprising outputting a confirmation based at least in part on the programing.

8. A system, comprising:
a transceiver configured to:
send, via a first communications link, a state change to the remote-controlled device based at least in part on a first device command sent to the remote-controlled device, wherein the state change represents a resulting state of the remote-controlled device after performance of the first device command;
receive, via the first communications link, a confirmation message from the remote-controlled device in response to the sending the state change;

a memory configured to store a command set for the remote-controlled device and a state configuration for the remote-controlled device;
at least one processor coupled to the memory and configured to:
generate the first device command to control the remote-controlled device based at least in part on a user input; and
program the state configuration for the remote-controlled device based at least in part on the received confirmation message; and

a transmitter configured to:
send, via a second communications link, the first device command to the remote-controlled device for performance by the remote-controlled device; and
send, via the second communications link, a second device command for controlling the remote-controlled device based at least in part on the programming.

9. The system of claim 8 , wherein the first communications link is a bidirectional communication link that uses a radio frequency signal.

10. The system of claim 8 , the at least one processor further configured to:
update the state configuration for the remote-controlled device based at least in part on the sent state change.

11. The system of claim 8 , wherein the transmitter is configured to send the second device command via the second communications link based at least in part on the stored command set for the remote-controlled device.

12. The system of claim 8 , wherein the remote-controlled device is a television or set top box.

13. The system of claim 8 , the at least one processor further configured to:
output a confirmation based at least in part on the programing.

14. A tangible computer-readable device having instructions stored thereon that, when executed by at least one computing device, causes the at least one computing device to perform operations comprising:
performing a first device command at a remote-controlled device based at least in part on a user input;
sending, via a first communications link, a state change for the remote-controlled device to a universal remote control based at least in part on the performing the first device command;
receiving, via the first communications link, a confirmation message at the remote-controlled device in response to the sending the state change;
determining the universal remote control updated a stored state configuration for the remote-controlled device based at least in part on the received confirmation message; and
enabling receiving, via a second communications link, a second device command for controlling the remote-controlled device from the universal remote control based at least in part on the determining.

15. The tangible computer-readable device of claim 14 , wherein the first communications link is a bidirectional communication link that uses a radio frequency signal.

16. The tangible computer-readable device of claim 14 , wherein the second communications link is a unidirectional communication link that uses an infrared signal.

17. The tangible computer-readable device of claim 14 , the sending further comprising:
sending, via the first communications link, the state change for the remote-controlled device to the universal remote control based at least in part on pairing information stored at the remote-controlled device.

18. The tangible computer-readable device of claim 14 , wherein the universal remote control is programmed to send the second device command via the second communications link based at least in part on a command set for the remote-controlled device.

19. The tangible computer-readable device of claim 14 , wherein the remote-controlled device is a television or set top box.

20. The tangible computer-readable device of claim 14 , the operations further comprising:
outputting a confirmation based at least in part on the determining.
