Secure videoconferencing equipment switching system and method
| DWPI Title: System for switching e.g. audio/visual components, between videoconference systems, has memory encoded with relay configuration, where configuration corresponds to two electromechanical relays when selected mode is one specific mode |
| Abstract: Examples of systems described herein include videoconferencing systems having audio/visual components coupled to a codec. The codec may be configured by a control system. Communication networks having different security levels may be alternately coupled to the codec following appropriate configuration by the control system. The control system may also be coupled to the communication networks. |
| Use: System for switching electrical components e.g. audio/visual components, between videoconference systems. Uses include but are not limited to cameras, microphones, video monitors, computers, displays, DVD players and keyboards. |
| Advantage: The control system can only be connected to a lower security or unclassified network such as Ethernet network , so that the control system can be prevented from altering the system by allowing connection only to a lower security or unclassified communication network. The system enables a switching unit to be supplied in a 1 rack unit (1 RU) configuration having height of 1 and three by four inches, thus saving space in computing rack. The system uses a dense printed circuit board to provide the interconnections within the switching unit, and uses a twelve-layer printed circuit board to provide many planes and reduce the overall space required by the switching unit. |
| Novelty: The system (100) has a codec (115) coupled to a set of audio/visual components (110) and receiving audio, visual or both types of signals from the components. A control system (120) is coupled to the codec, and controls the codec. A memory (172) is encoded with a relay configuration associated with a set of modes for the system. The relay configuration corresponds to a first electromechanical relay (140) connecting the codec to an interface and a second electromechanical relay (142) disconnecting the control system from another interface when a selected mode is one specific mode. |
