A videoconferencing device that determines a spatial arrangement of the video streams output at a first endpoint based on a number of display devices being utilized at the first endpoint and a number of cameras being utilized at each of the one or more additional endpoints.

Automated layouts optimized for multi-screen and multi-camera videoconferencing calls

A videoconference multipoint control unit (MCU) automatically generates display layouts for videoconference endpoints. Display layouts are generated based on attributes associated with video streams received from the endpoints and display configuration information of the endpoints. An endpoint can include one or more attributes in each outgoing stream. Attributes can be assigned based on video streams' role, content, camera source, etc. Display layouts can be regenerated if one or more attributes change. A mixer can generate video streams to be displayed at the endpoints based on the display layout.

Automatic video layouts for multi-stream multi-site presence conferencing system

A videoconferencing system includes a touch screen display device and a videoconferencing unit. The display device displays video data for the videoconference and generates touch data based on user selections relative to the touch screen. The videoconferencing unit is operatively coupled to the touch screen device by a video connection and a data interface connection, for example. The unit establishes and conducts a videoconference with one or more endpoints via a network. The unit sends video data to the display device and receives touch data from the device. The received touch data is used to control operation of the videoconferencing system. The received touch data can be used to initiate a videoconference call, change an operating parameter, change orientation of a camera, initiate a picture-in-picture display, access a menu, access memory, change a source of video data, initiate a whiteboard display, and access a screen of a connected device.

System and method for controlling videoconference with touch screen interface

A videoconferencing system for enhanced telepresence employs a single wide aspect ratio high resolution camera for capturing video images of near end conference participants. Captured video image can be divided into adjacent portions, where video images corresponding to each portion is separately encoded and sent to a far end videoconferencing system to be displayed on adjacently placed display devices. Misalignment in displayed images at the far end can be mitigated by selecting portions that are non-overlapping and horizontally aligned. Number and size of the portions can be determined based on configuration information of the far end videoconferencing system.

An integrated videoconferencing system has a credenza that houses three displays at predefined angles with respect to one another. A table positions in from the credenza for seating participants across from the credenza's displays. The table has three seating sections that are angled at another predefined angle with respect to one another. Three cameras are positioned in the top of the credenza, and each has a view angle directed perpendicularly at one of the seating sections. The table can also have a portion that interconnects with the credenza. In use, the integrated system allows the participants to conduct a telepresence videoconference in which the near-end participants can interact with the far-end participants as if they were all seated at the same conference table in the room together.

Controlling videoconference with touch screen interface

Automatic video layouts for multi-stream multi-site telepresence conferencing system

Methods and apparatuses for automating the interface of different videoconferencing systems are disclosed. In brief, according to one or more embodiments according to the invention, a first method comprises, upon connection of two videoconferencing systems, information containing the number and type of screens in each system is exchanged, and this information is used to set up custom camera and/or display settings in each local system.

Configuring videoconferencing systems to create video sessions with realistic presence

A portable integrated videoconferencing unit has an integral housing in which an interior chamber houses an electronics board for performing video, audio, and communications processing. Integrally mounted on the housing are a video camera and preferably a microphone array for providing directive audio processing. The electronics board receives and processes video and audio outputs of the camera and microphone array respectively, and generates compressed video and audio outputs for transmission over the communications channel. The electronics board also receives compressed video conferencing signals from the channel and processes those signals to generate the appropriate video and audio signals for connection to a video monitor. Various elements are isolated from the microphones to reduce noise and vibration, and an answer bar can be mounted on the integrated unit to provide an easy known answer capability where an automatic answering mode is not desired. The software of the unit can be upgraded during a videoconference call with an upgrade server.

Three terms (X,Y,'Error') are combined in a single floating-point number in an advanced microprocessor to compute pixel addresses. The floating-point number is reconverted to integer form in multiplexers operating in a mode determined by slope, relative to unity, of the line to be defined by the pixels. The output of the multiplexers is enhanced by a look-up table to produce color data, which are converted to analog form for display. Speed of operation is greatly augmented by the use of floating-point arithmetic to compute the pixel addresses.

This is a method and apparatus for use in the 'color-graphics board' of a computer having a pictorial output visualizable in color. It is particularly suitable for use with computers of the Macintosh type of configuration, but is by no means limited to computers of that type. The invention affords to the operator of the computer the ability to select various bit levels for the pixels which together comprise the display of the computer. The bit levels may be selected at will depending upon the necessary degree of resolution and color selectability that characterize the diverse possible uses of the visual display of the computer.
