Abstract: A logical module, referred as Load Balancer Module (LBM), is disclosed which listens to one of certain common predefined port number. These well-known ports for receiving communication video conference signaling and control protocols is thereafter load balanced and multi-plexed to a number of instances of protocol stack applications. By balancing the multi-media data stream across a multitude of application instances multiple multi-media data streams may be serviced and processed by a single internet protocol host processor. A multipoint control unit (MCU) may therefore process multiple input data streams containing multi-media video conferencing information.

Abstract: A digital storyboard system that uses multiple displays and related methods are disclosed. The systems and methods may be used to present graphical content such as slides of a slide shows or boards of a storyboard sequence simultaneously on multiple screens at each of a plurality of locations. One or more users of the system may, through their interface device, update or edit the content on any of the screens, resulting in real-time updates to those designated screens at all locations and on any interface devices on which those screens appear. Portable devices may be used to interface with the storyboard system to choose content, place content on display areas, edit and annotate content. Concurrent editing and/or annotating of content by multiple users is supported. The systems and methods may also partition screens at a plurality of locations into display areas to display different content, such that all content is visible at all locations, regardless of the number of available screens.

Abstract: A videoconferencing system includes at least one processor and at least one camera. The endpoint can capture one or more images with the camera. The system can locate a region of interest within an image, such as the area surrounding the face of a person participating in a videoconference. If the face area or other region of interest is too dark, the system can brighten the region to make it more visible. The system can determine whether the face is too dark by comparing the captured image to previously captured images, or comparing the luma values and other data making up the face to predetermined values, or both. The system can check the second image for over-brightening or saturation, and further adjust the image as needed. The brightening of the face area is done in such a way that the brightened region is unobtrusive to the viewer.

Abstract: An endpoint optimizes bandwidth by initiating a peer-to-peer conference with a plurality of remote devices, generating a first quality list comprising a first device of the plurality of remote devices from which to receive a first data stream at a first quality level, transmit a request to the first device to receive the first data stream at the first quality level, determining that a second device of the plurality of remote devices is not a member of the first quality list, and in response to determining that the second device of the plurality of remote devices is not a member of the first quality list, transmitting a request to the second device to receive a second data stream at a second quality level.

Abstract: A light-emitting diode (LED) speaker identification system that illuminates at least one LED in the direction in which a camera having a 360 degree field of view is recording. The LED speaker identification system includes a base, a printed circuit board coupled to a surface of the base, and a plurality of light-emitting diodes (LEDs) coupled to a surface of the printed circuit board around a circumference thereof. The plurality of LEDs are electrically connected to a camera having a 360 degree viewing angle.

Abstract: A P2P configuration where only the active talker or talkers are providing media streams, to reduce uplink bandwidth demands on an active talker, participants relay the active talker stream to other participants. A signaling server determines the closest participant receiving a requested stream and with available bandwidth to relay the requested stream to a requesting participant and controls the provision of the relayed stream. In certain cases, an additional intermediate participant may relay the requested stream.

Abstract: A videoconferencing system has a videoconferencing unit that use portable devices as peripherals for the system. The portable devices obtain near-end audio and send the audio to the videoconferencing unit via a wireless connection. In turn, the videoconferencing unit sends the near-end audio from the loudest portable device along with near-end video to the far-end. The portable devices can control the videoconferencing unit and can initially establish the videoconference by connecting with the far-end and then transferring operations to the videoconferencing unit. To deal with acoustic coupling between the unit's loudspeaker and the portable device's microphone, the unit uses an echo canceller that is compensated for differences in the clocks used in the A/D and D/A converters of the loudspeaker and microphone.

Abstract: Blurriness in a video image transmitted over a lossy network can be reduced by filtering the decoder output to determine whether updating of the reference frame based on the current video data is indicated. An update may be appropriate if the decoder output is sharper than the contents of the display buffer after the last update. Additionally, an update may be appropriate if there was a significant change to the underlying image, and thus to the encoder's input. Whether such a change has occurred can be determined by analyzing the prediction mode, motion vectors, and pixel data of the output image.
