Pairing Devices in Conference Using Ultrasonic Beacon amd Subsequent Control Thereof
First Claim
1. A method implemented at a first device for conferencing the first device and a second device in a near-end environment with a far-end, comprising:
- connecting the first device in the near-end environment to the far-end with a far-end connection;
outputting connection information in an imperceptible acoustic beacon in the near-end environment with the first device;
connecting the first device via a near-end connection with the second device in the near-end environment based on the second device using the output connection information;
obtaining, at the first device via the near-end connection, a control from the second device; and
operating a function of the first device in response to the control.

Abstract
A videoconferencing system has a videoconferencing unit that use portable devices as peripherals for the system. The portable devices obtain near-end audio and send the audio to the videoconferencing unit via a wireless connection. In turn, the videoconferencing unit sends the near-end audio from the loudest portable device along with near-end video to the far-end. The portable devices can control the videoconferencing unit and can initially establish the videoconference by connecting with the far-end and then transferring operations to the videoconferencing unit. To deal with acoustic coupling between the unit'"'"'s loudspeaker and the portable device'"'"'s microphone, the unit uses an echo canceller that is compensated for differences in the clocks used in the ND and D/A converters of the loudspeaker and microphone.
