摘要： Disclosed herein are methods and systems for providing continuous presence video stream in a cascading video conference, i.e., a video conference that is conducted over more than one MCU. A cascading continuous presence composition controller (CCCC) selects which endpoints from among all of the endpoints participating in the conference should be displayed in the layout, regardless of which endpoints are associated with which MCU. The CCCC can be resident on one of the MCUs, resident on a cascading conference server, or can be distributed among all of the MCUs involved in a cascading conference.

摘要： A system and method is disclosed for composing a video layout having an aspect ratio of 16:9 from a plurality of video segments having an aspect ratio other than 16:9. For example, the plurality of video segments might have an aspect ratio of 4:3. To create a composite frame having an aspect ratio of about 16:9, the disclosed system scales each one of the segments and places each scaled segment in the layout in such a way that the composite layout has an aspect ratio of about 16:9.

摘要： An improved method and a system of utilizing the decoding/encoding video resources of a Video Processing Device (VPD) by offering a distributed architecture. A conventional VPD comprises a plurality of video ports, each video port is dedicated to a user and comprises at least one decoder and one encoder. The distributed VPD comprises a plurality of input ports and a plurality of output ports. Each input port includes an input module. The input module is operative to receive a compressed video input stream, manipulate the compressed video stream into a primary stream and optionally generate a secondary data stream associated with the primary data stream. A variety of levels of service for a session can be offered. A client may select the number of ports that will be used by the session. For example, a single port may multicast its compressed output video stream to all the destinations within a session, or to all destinations within a plurality of ports. The multicasting may be such that there is anywhere from one port for each group of destinations using the same compressed video stream to one port for each user.
摘要翻译：通过提供分布式架构来利用视频处理设备（VPD）的视频资源的解码/编码的改进方法和系统。传统的VPD包括多个视频端口，每个视频端口专用于用户，并且包括至少一个解码器和一个编码器。分布式VPD包括多个输入端口和多个输出端口。每个输入端口包括一个输入模块。输入模块可操作以接收压缩视频输入流，将压缩的视频流操纵成主流并且可选地生成与主数据流相关联的辅助数据流。可以提供各种会话级别的服务。客户端可以选择会话使用的端口数量。例如，单个端口可以将其压缩输出视频流多播到会话内的所有目的地，或多个端口内的所有目的地。多播可以使得对于每个目的地的一组端口的任何地方使用相同的压缩视频流到每个用户的一个端口。

摘要： An association of videoconferencing services is disclosed that enables two or more videoconferences to be generated with each videoconference running independently from the others and having its own conferees. The association is achieved by having at least one conferee (a traveler) that can “move” or “travel” from one videoconference to another in the association. The one or more travelers belong to the association and not to any particular videoconference. In exemplary embodiments, the traveler can choose between the various associated videoconferences by making a selection to a multipoint control unit (MCU) that controls the associated videoconferences.

摘要： A multipoint control unit (MCU) or other digital video-processing apparatus operates to manipulate compressed digital video from several compressed digital video sources. The apparatus has a plurality of video input modules and a plurality of video output module. Each of the video input modules receives a compressed video signal from one of the sources and generally decodes the data into a primary data stream and a secondary data stream. The video output module receives the primary and secondary data streams, from at least one of the input module for generally encoding to a compressed output stream for transmission.

摘要： A multipoint control unit (MCU) for facilitating communication between a plurality of endpoints. Each endpoint sends a compressed video signal and receives a compressed video signal. The MCU has a plurality of video input modules and a video output module. Each of the video input modules receives a video signal from one of the endpoints and generally decodes the data into a primary data stream and a secondary data stream. The video output module includes a rate control unit and a generalized encoder that receive the primary and secondary data streams for generally encoding to a compressed output stream for transmission to an endpoint.
