摘要:
A personal videoconferencing system includes a videoconferencing appliance connected to a personal computer through a Universal Serial Bus (USB) or similar connection. The appliance is provided with a video camera and microphone for generating local video and audio streams. The local video and audio streams are compressed by a video and audio encoder residing at the appliance, and the compressed video and audio streams are conveyed to the personal computer over the USB connection. The appliance may be further provided with an audio decoder for decompressing a remote audio stream received by the personal computer through a network interface and conveyed to the appliance via the USB connection. A video decoder, located on the personal computer, is configured to decompress the local video stream (received through the USB connection) as well as a remote video stream received through the network interface. The decompressed video streams are then sent to a monitor for display to a user. The decompressed audio stream may be played either at a loudspeaker coupled to the audio decoder or at the personal computer.

In some embodiments, the components of a videoconferencing system may be incorporated in a unitary housing. For example, an integrated videoconferencing system may include microphones to capture participant audio and a camera to capture participant video (along with corresponding audio processing capabilities) in a unitary housing. The unitary housing may also include speakers to produce audio from conference participants and a display to provide video of conference participants. The integrated videoconferencing system may include a codec for encoding and/or decoding). The integrated videoconferencing system may also perform other conference related functions. The integrated videoconferencing system may be used as a speakerphone (e.g., in audio only calls) and/or a videoconference system. The integrated videoconferencing system may also fold into a compact form for portability.

In various embodiments, a multi-component videoconferencing system (MCVCS) may be used as a videoconferencing endpoint. The MCVCS may include a camera, microphones, speakers, and a codec. The camera and speakers may be coupled to or placed around a display. The MCVCS may send/receive signals through a network coupled to the computer system. The various functions to support the videoconference (e.g., compression and decompression of video signals) may be performed by circuitry in the camera base, codec box, and/or on the computer system. The computer system may be a laptop computer. In some embodiments, the codec functionality may be incorporated in a set-top box. In some embodiments, the components of the MCVCS may be incorporated into a unitary housing. In some embodiments, ported speakers may be used to maximize sound quality for the provided speaker size.

In various embodiments, a camera may be controlled by one or more motors in a base of the camera. Cables and other components may be used to manipulate the camera lens through the side arms of the camera. Putting the motors in the base may reduce the size of the outer case of the camera and add stability. A pan motor may pan the camera while a tilt motor may move a tilt pulley relative to a lens portion of the camera (which may or may not tilt the camera depending on the panning motion of the camera). In some embodiments, images from the camera may be converted into a serialized stream and transported over a cable from the lens through a center shaft of the camera.

In various embodiments, a High Definition (HD) camera may be controlled by one or more motors in a base of the HD camera. Cables and other components may be used to manipulate the camera lens through the side arms of the HD camera. Putting the motors in the base may reduce the size of the outer case of the HD camera and add stability. In some embodiments, images from the HD camera may be converted into a serialized stream and transported over a cable from the lens through a center shaft of the HD camera. Other components may also be used to increase the functionality of the HD camera. In some embodiments, a camera support mechanism may be provided to couple a camera to a display. The camera support mechanism may include a front lip and rear leg to hold camera in place.

A videoconferencing system includes an embedded web server and a network interface for connecting the videoconferencing systems to a network. Computers and other devices on the network may manage and control various operations of the videoconferencing system through a conventional browser interface by accessing web pages transmitted by the embedded web server. In addition, users of network-connected computers may upload presentation files to the videoconferencing system to enable transmission of presentation slides to remote conference endpoints. The videoconferencing system may also be provided with an integrated network hub to allow connection of the videoconferencing system to one or more local computers.
摘要:
A videoconference system can automatically transmit first and second images from a local site to a remote site where the first image is a high-resolution live image and the second image may be transmitted either as a high-resolution live or still frame image. Two video streams representing the first and second images are transmitted together to the remote site within a single carrier channel. The second image is transmitted as a still image whenever the second image is static to conserve bandwidth.

Various embodiments of a system and method for selecting a video input signal to send to remote endpoints in a videoconference are disclosed. The method may comprise simultaneously displaying a plurality of icons on a display device, where each icon displays a live version of a video input signal from a respective local video source. The icons are selectable to select a video input signal to send to the remote endpoints in the videoconference. In other words, by selecting a particular icon, a user can select the video input signal displayed by the icon as the video input signal to send to the remote endpoints.
