A system includes microphone devices, echo cancellation mechanism, and speaker devices. Each echo cancellation mechanism corresponds to one of the microphone devices. Each speaker device corresponds to a sound source signal. Each sound source signal is spatially distributed to all the speaker devices, and each echo cancellation mechanism receives as a reference signal a combination of all the sound source signals.

Echo cancellation in which sound source signals are spatially distributed to all speaker devices

A system and method is disclosed for harmonizing calibration of audio between a plurality of networked conference rooms to enable each networked conference room to have substantially similar audio characteristics by adjusting speaker gain output of an audio signal sent from a calibration location on a network and tuning microphone response received at a calibration location to a calibrated audio source.

System and method for harmonizing calibration of audio between networked conference rooms

A system including at least one system microphone, a processor connected to computer readable memory and the at least one system microphone, a measurement microphone connected to the processor, at least one audio speaker, a signal generator connected to the processor and configured to produce signals from the at least one audio speaker for both the measurement microphone and the at least one system microphone to measure the response of the at least one audio speaker, and a device manager application executable from the computer readable memory and configured to perform the steps of calibrating the at least one audio speaker with the measurement microphone using the signals of the signal generator based on the response of the at least one audio speaker thereby creating at least one calibrated audio speaker and calibrating the at least one system microphone with the at least one calibrated audio speaker using the signals of the signal generator.

Calibrating at least one system microphone

Cameras are adjusted by setting magnifications of two or more cameras to be substantially equal, focusing the two or more cameras, and setting the two or more cameras so that portions of an object captured thereby when displayed are aligned.

Camera adjustment

A system including a first node configured to receive first data in a first format that specifies a network destination for the first data and convert the first data to second data in a second format that does not specify a network destination for the second data and a second node configured to receive the second data from the first node over a first connection and convert the second data to third data in a third format that specifies a network destination for the third data is provided.

Converting data from a first network format to non-network format and from the non-network format to a second network format

Systems and methods for managing virtual collaboration systems are disclosed herein. A virtual collaboration system includes a distributor communicatively coupled to a first network and a second network having different network characteristics from the first network, the distributor configured to receive first media streams from at least one first network node, and to transmit the first media streams to at least one second network node; and a management subsystem adapted to dynamically configure a topology of a virtual collaborative event, wherein configuration of the topology includes a determination of media stream connections among the distributor and the at least one first network node based, at least in part, on at least one policy, and wherein the media stream connections establish and maintain virtual relationships among the at least one first network node and the at least one second network node.

Systems and methods for managing virtual collaboration systems

An apparatus has a content node to logically select a first A/V stream from an application layer of a first network and a collaboration node to logically select a second A/V stream from an application layer of a second network. A set of non-network media link interfaces are configured to transmit the second A/V stream from the collaboration node to the content node, and to transmit the first A/V stream from content node to the collaboration node. The non-network media link interfaces provide for limited information encoding to prevent network protocol information from being transferred between the first and second networks.

Synthetic bridging for networks

A technique for maintaining consistent video quality between a plurality of videoconference sites is disclosed. Calibration correction factors are determined from video calibration data obtained from the videoconference sites. The calibration factors are applied to transmissions between the videoconference sites.

Consistent quality for multipoint videoconferencing systems

A method of creating a synthetic bridge () has select data () logically extracted from an application layer of a first network (A) which contains one or more first data streams to be transported to a second network (B). Select data () is logically extracted from an application layer of the second network (B). Select data () is logically extracted from an application layer of the second network (B) which contains one or more second data streams to be transported to the first network (A). The two or more first and second data streams are transported over separate sets of non-network media link interfaces (-) that only allow for limited information encoding and inherently prevent any network protocol information from being passed with the two or more first and second data streams until after the two or more first and second data streams are in the control of the opposite network from which they were transported.

Various embodiments and methods relating to a camera mount are disclosed.
