Abstract: A bidirectional transceiver includes a media transmitter, a media receiver, a network transmitter, and a network receiver. Each of these components includes an interface to a respective differential wire pair of a cable. By coupling a pair of such transceivers, a media stream and network connectivity can be sent over the cable in either or both directions. Using an opportunistic scheduling method, each media stream can contain audio, video, and control information in uncompressed form. Power can be transferred over the cable so that a media device containing one transceiver can be powered by a media device containing the other transceiver.

Abstract: A video conferencing/presentation system includes a PC docking station and a room media unit. The dock includes speakerphone and tactile user interface. The wall-mounted RMU, including a wide field camera and speaker(s), is coupled to a monitor. The dock communicates with the RMU. A speakerphone mic captures room audio. During conferencing, room audio and camera video are sent to a docked PC; the PC communicates with remote nodes using video chat software, sending room A/V; remote A/V is received from the PC by the dock, and transmitted for RMU output. During presentation, room audio, and/or PC media software presentation, may be output through the RMU, or to the PC for remote transmission. The dock provides the PC network access. Dock/RMU may each be equipped with a bidirectional transceiver, which uses prioritized opportunistic sequencing to assemble/disassemble a combined media/control packet stream over a cable, and transfer power from dock to RMU.

Abstract: The present invention is a video production and control system that uses a touch screen display and user interface, managed by a controller, for video source control. The system may include a set of touch screen windows that display feeds from sources of video information. For a selected feed window, the system displays a set of representations of preset configurations of the video source, which might be a camera, a video recorder, a handheld device, a storage device, a computer, or other source of video data. The representations may be thumbnail images of a view through the video source when it has the corresponding configuration. Selecting a different thumbnail using the touch screen will cause a controller to send control data through an output port that directs the video source to assume the newly chosen preset configuration.

Abstract: The present invention is a video production and control system that uses a touch screen display and user interface, managed by a controller, for video switching. The system is used to select Preview and Program video feeds from a set of video input feeds. The video source configuration for some of the feeds may have been selected using touch screen video source control technology. Over time, the user can use the touch screen controls to switch which feeds are then designated as the Preview and Program feeds. The evolving Program signal is sent to a Program output connection for consumers of the Program, possibly after some reformatting. The current Program feed may be promoted from the current Preview feed. User controls determine the type of transition, such as cut or crossfade, that will apply to a transition from Preview to Program.

Abstract: The present invention is a camera control system designed for video capture of a presentation made in a lecture hall or similar place. The system combines preset views triggered by presence-sensing devices at fixed locations with views tracking the motion of the presenter elsewhere. A tracking camera displays a preset view when the presenter steps on a switch mat or enters into the region of detection of some other presence sensor such as an infrared sensor. At other times, the tracking camera is guided by motion detection logic that uses a wide field of vision provided by a reference camera. The reference camera, the tracking camera, and the presence-sensing devices are integrated by a controller. Various parameters can be configured by a user through a graphical user interface on a computer, manual controls on the box housing the controller, or a hand-held remote control device.
