Abstract

A candidate companion screen device is located by a primary display device as being in the same room as the primary device using IRDA, and in response ancillary content related to content being shown on the primary display device is provided to the companion screen device. The ancillary content may be provided from the Internet based on information in the content being presented on the primary display device by, e.g., providing a link to a website to the companion device.

Claims

1. A device comprising:

at least one computer memory that is not a transitory signal and that comprises instructions executable by a processor for;

transmitting, from a primary display device (PDD), a wireless message containing a value instructing a receiving candidate companion screen device (CCSD) to respond to the message using infrared (IR) transmission, the value instructing a receiving CCSD to respond to the message with a specific response code over IR;

determining whether a CCSD responds to the message with an IR response message conforming to the specific response code, the PDD being configured for presenting primary content; and

responsive to determining that the CCSD responds to the message with an IR response message conforming to the specific response code, causing ancillary content related to but different from the primary content to be provided to the CCSD for presentation of the ancillary content thereon, and/or causing a message regarding accessing ancillary content different from the primary content to be provided to the CCSD for presentation of the message thereon.

2. The device of claim 1, wherein the device is implemented by the PDD.

3. The device of claim 1, wherein the wireless message is sent using Bluetooth and the response message is sent using IR.

4. The device of claim 1, wherein the wireless message is sent using Wi-Fi and the response message is sent using IR.

5. The device of claim 1, wherein the wireless message is sent using IR and the response message is sent using IR.

13. The device of claim 1, wherein the instructions are executable for:

responsive to determining that the CCSD responds to the message with an IR response message conforming to the specific response code, causing ancillary content related to but different from the primary content to be provided to the CCSD for presentation of the ancillary content thereon.

14. The device of claim 1, wherein the instructions are executable for:

responsive to determining that the CCSD responds to the message with an IR response message conforming to the specific response code, causing a message regarding accessing ancillary content different from the primary content to be provided to the CCSD for presentation of the message thereon.

15. The device of claim 1, comprising the processor.

6. A device comprising:

at least one computer readable storage medium comprising instructions executable by a processor for undertaking logical steps;

at least one processor configured for accessing the computer readable storage medium to execute the instructions to configure the processor for undertaking the logical steps, the logical steps embodied by the instructions and undertaken by the processor comprising;

transmitting, from a primary display device (PDD), a wireless message containing a value instructing a receiving candidate companion screen device (CCSD) to respond to the message using infrared (IR) transmission, the message instructing a receiving CCSD to respond to the message with a specific response code over IR;

determining whether a CCSD responds to the wireless message with an IR response message conforming to the specific response code,

the PDD being configured for presenting primary content; and

responsive to determining that the CCSD responds to the wireless message with an IR response message conforming to the specific response code, causing ancillary content related to the primary content and different therefrom to be provided to the CCSD for presentation of the ancillary content thereon, and/or causing a message regarding accessing ancillary content to be provided to the CCSD for presentation of the message thereon.

7. The device of claim 6, wherein the device is implemented by the PDD.

8. The device of claim 6, wherein the wireless message is sent using Bluetooth or Wi-Fi and the response message is sent using IR.

9. The device of claim 6, wherein the wireless message is sent using IR and the response message is sent using IR.

16. The device of claim 6, wherein the logical steps comprise:

responsive to determining that the CCSD responds to the wireless message with an IR response message conforming to the specific response code, causing ancillary content related to the primary content and different therefrom to be provided to the CCSD for presentation of the ancillary content thereon.

17. The device of claim 6, wherein the logical steps comprise:

responsive to determining that the CCSD responds to the wireless message with an IR response message conforming to the specific response code, causing a message regarding accessing ancillary content to be provided to the CCSD for presentation of the message thereon.

20. The device of claim 6, wherein the wireless message is sent using Bluetooth and the response message is sent using IR.

21. The device of claim 6, wherein the wireless message is sent using Wi-Fi and the response message is sent using IR.

10. A method comprising:

receiving at a candidate companion screen device (CCSD) a wireless message from a primary display device (PDD), the PDD being configured for presenting primary content, the wireless message containing a value instructing the CCSD to respond to the wireless message using infrared (IR) transmission, the message instructing a receiving CCSD to respond to the message with a specific response code over IR; and

responsive to receiving the wireless message, sending an IR response message to the PDD which if received by the PDD causes ancillary content related to the primary content and different therefrom to be provided to the CCSD for presentation of the ancillary content thereon, and/or causes a message regarding accessing ancillary content to be provided to the CCSD for presentation of the message thereon.

11. The method of claim 10, wherein the wireless message is sent using Bluetooth or Wi-Fi and the response message is sent using IR.

12. The method of claim 10, wherein the wireless message is sent using IR and the response message is sent using IR.

18. The method of claim 10, comprising:

responsive to receiving the wireless message, sending an IR response message to the PDD which if received by the PDD causes ancillary content related to the primary content and different therefrom to be provided to the CCSD for presentation of the ancillary content thereon.

19. The method of claim 10, comprising:

responsive to receiving the wireless message, sending an IR response message to the PDD which if received by the PDD causes a message regarding accessing ancillary content to be provided to the CCSD for presentation of the message thereon.

22. The method of claim 10, wherein the wireless message is sent using Bluetooth and the response message is sent using IR.

23. The method of claim 10, wherein the wireless message is sent using Wi-Fi and the response message is sent using IR.
