Abstract

The disclosure relates to a method, apparatus and system to provide automated audio video conferencing in a conference room. In an exemplary embodiment, the disclosure relates to a mobile device having one or more processors and circuitry. The circuitry may execute a first logic, a second logic and a third logic. The first logic may be configured to receive instructions to connect the mobile device to a wireless equipment in a conference room. The second logic may be configured to obtain conference room information. The third logic may be configured to transmit a request to pair with a wireless equipment in the conference room. The third logic may be further configured to: receive information in a first communication mode that a code challenge will be issued, receive a code challenge in the second communication mode and pair the mobile device with the wireless equipment.

First claim

What is claimed is:

1. A video conference device comprising:
at least one processor;
memory to store instructions; and
a communication interface to transmit from and receive signals for the processor,
the at least one processor to execute the instructions to at least:
in a first communication mode, transmit, via the communication interface, a code and an address of the video conference device in a first ultrasound message;
establish, via the communication interface, a Wi-Fi connection with a mobile device in a second communication mode based on the address from the first ultrasound message;
in the second communication mode, pair the video conference device with the mobile device based on authentication of the code when the mobile device is in proximity to the video conference device;
in the second communication mode, enable control of operation of the video conference device by the mobile device via the Wi-Fi connection while the mobile device is in proximity to and paired with the video conference device; and
after an end of the pairing, return to the first communication mode to transmit, via the communication interface, the code and the address of the video conference device in a second ultrasound message.

2. The video conference device of claim 1 , wherein the communication interface includes an ultrasound transmitter.

3. The video conference device of claim 1 , wherein the communication interface includes a Wi-Fi transceiver.

4. The video conference device of claim 1 , wherein the video conference device is to establish a content session based on a command from the mobile device via the Wi-Fi connection.

5. The video conference device of claim 1 , wherein the at least one processor is to receive commands from the mobile device via the Wi-Fi connection, the mobile device to serve as a remote control for the video conference device via the Wi-Fi connection.

6. The video conference device of claim 1 , further including a wireless sensor to detect the mobile device in proximity to the video conference device, the wireless sensor to trigger the transmission of the code and the address of the video conference device in the first ultrasound message when the mobile device is detected in proximity to the video conference device.

7. The video conference device of claim 1 , wherein the mobile device is in proximity to the video conference device when the mobile device is in a same room as the video conference device.

8. A wireless projector comprising:
at least one processor;
memory to store instructions; and
a communication interface to:
in a first communication mode, transmit a code and an address of the wireless projector in a first ultrasound message;
receive the code over a Wi-Fi connection established between the wireless projector and a mobile device in a second communication mode based on the address from the first ultrasound message; and
in the second communication mode, pair the wireless projector with the mobile device based on authentication of the code when the mobile device is in proximity to the wireless projector,

the at least one processor to execute the instructions to enable, in the second communication mode, control of operation of the wireless projector by the mobile device via the Wi-Fi connection while the mobile device is in proximity to and paired with the wireless projector, and after an end of the pairing, the at least one processor to execute the instructions to return to the first communication mode to transmit, via the communication interface, the code and the address of the wireless projector in a second ultrasound message.

9. The wireless projector of claim 8 , wherein the communication interface includes an ultrasound transmitter.

10. The wireless projector of claim 8 , wherein the communication interface includes a Wi-Fi transceiver.

11. The wireless projector of claim 8 , wherein the at least one processor is to establish a content session based on a command from the mobile device via the Wi-Fi connection.

12. The wireless projector of claim 8 , wherein the communication interface is to receive commands from the mobile device via the Wi-Fi connection, the mobile device to serve as a remote control for the wireless projector via the Wi-Fi connection.

13. The wireless projector of claim 8 , further including a wireless sensor to detect the mobile device in proximity to the wireless projector, the wireless sensor to trigger the communication interface to transmit the code and the address of the wireless projector in the first ultrasound message when the mobile device is detected in proximity to the wireless projector.

14. At least one storage device comprising instructions that, when executed, cause a mobile device to at least:
in a first communication mode, detect a code in a first ultrasound message from a video conference device, the first ultrasound message including the code and an address of the video conference device;
establish a Wi-Fi connection with the video conference device in a second communication mode based on the address from the first ultrasound message;
in the second communication mode, pair the video conference device with the mobile device based on authentication of the code when the mobile device is in proximity to the video conference device;
in the second communication mode, control operation of the video conference device via the Wi-Fi connection while the mobile device is in proximity to and paired with the video conference device; and
after an end of the pairing, return to the first communication mode to detect the code and the address of the video conference device in a second ultrasound message.

15. The at least one storage device of claim 14 , wherein the instructions, when executed, cause the mobile device to detect the code by processing a signal received via an ultrasound transceiver of the mobile device.

16. The at least one storage device of claim 14 , wherein the instructions, when executed, cause the mobile device to facilitate the Wi-Fi connection via a Wi-Fi transceiver.

17. The at least one storage device of claim 14 , wherein the instructions, when executed, cause the mobile device to establish a content session with the video conference device via the Wi-Fi connection.

18. The at least one storage device of claim 14 , wherein the instructions, when executed, cause the mobile device to remotely control the video conference device via the Wi-Fi connection.

19. A mobile device comprising:
