Patent application number | Description | Published |
20090034712 | Echo cancellation in which sound source signals are spatially distributed to all speaker devices - 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. | 02-05-2009 |

20090300198 | CONNECTING COLLABORATION NODES - 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. | 12-03-2009 |
20090323552 | Systems and Methods for Managing Virtual Collaboration Systems Spread Over Different Networks - 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. | 12-31-2009 |
20100135501 | CALIBRATING AT LEAST ONE SYSTEM MICROPHONE - 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. | 06-03-2010 |
20100205319 | Synthetic Bridging for Networks - 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. | 08-12-2010 |
20100225733 | Systems and Methods for Managing Virtual Collaboration Systems - Systems and methods for managing virtual collaboration systems are disclosed herein. A virtual collaboration system includes a hoster configured to receive second media streams from at least a second node, and to transmit those streams from at least one simulated node to at least a first 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 at least one simulated node and the at least a first node based on at least one policy, and wherein the media stream connections establish and maintain virtual relationships among the at least one simulated node and the at least a first node. | 09-09-2010 |
20110134207 | Audio/video System - In an embodiment of an audio/video system, an audio signal is sent to a plurality of speakers of the audio/video system, and a delay and/or a gain applied to the audio signal sent to each speaker is adjusted according to a distance from that speaker to an apparent sound origin on a video display of the audio/video system. | 06-09-2011 |
