Abstract: An MRC system includes an MRM and an MRE that handle needs for Intra frames in an efficient way, improves the conferees experience, and reduces the load on the resources associated with that MRC videoconference by reducing the number of Intra frames and lowering the impact of Intra frames when they are needed. In some embodiments, when a requiring MRE requests an Intra frame for a video stream received from a presenting MRE, an MRM may respond by requesting the presenting MRE to send a temporary video stream toward the requiring MRE while sending in parallel a normal stream toward the rest of the MREs.

Abstract: Disclosed herein is a method and apparatus for videoconferencing that allows video images from two or more cameras at the same site to be displayed as a single panoramic image. Accordingly, a conferencing endpoint having a single monitor can display the panoramic image of the two or more video images from an endpoint having multiple cameras, such as a telepresence endpoint. A sliding display area can be used to manually define a zoomed portion of the panoramic image to be displayed. Alternatively, the zoomed portion may be determined automatically. The zoomed portion may be changed during the course of the conference.

Abstract: Disclosed are methods and systems for multipoint videoconferencing. A Media Relay MCU (MRM) receives compressed media (audio, video, and/or data) from a plurality of endpoints participating in a video conferencing session. For a given endpoint, the MRM selects which of other endpoints to display in a CP layout at the given endpoint. The MRM transmits the compressed media from the selected endpoints to the given endpoint to be presented in the CP layout. The MRM does not decode the compressed media.

Abstract: A bank of processing units is connected to a number of LANs via a bank of MAC controllers. An interconnect switch allows any of the processing units to access any of the MAC controllers. A housekeeping processor periodically detects faults in the connectivity of the processing units to the LANs. When a fault is detected, a redundant processing unit is assigned to be connected to the LAN. If a fault still exists, then a redundant MAC controller is assigned to the redundant processing unit. The MAC address of the previous MAC controller is reassigned to the redundant MAC controller.
