Pairing devices in conference using ultrasonic beacon and subsequent control thereof
First Claim
1. A method of conferencing over a network, the method comprising:
- outputting, in an imperceptible acoustic beacon in a near-end environment with a second device of a network system, connection information for connecting to a given device of the network system in the network, wherein the connection information comprises a network address of the given device encoded in the acoustic beacon;
connecting a first device in the near-end environment to the given device of the network system by receiving a response in the network system from the first device, the response being based on the first device using the output connection information and requesting connection of the first device to the given device of the network system;
obtaining, at the network system via the network, content from the first device; and
operating the network system using the obtained content.

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 A/D and D/A converters of the loudspeaker and microphone.
