摘要： The present invention is a method and system for reducing delay in video communication, including, for example, video transcoding and continuous presence in a multipoint multimedia conference. The video communication control unit reduces such delay by processing a video stream in a small number of macroblocks referred to as “chunks,” without waiting to get a full frame of video data. Instead, the incoming video stream is converted into decoded chunks. These decoded chunks are transferred to an output module without waiting to decode an entire frame. An encoder in the output module encodes the decoded chunks (also referred to as encoder chunks), and transfers them to an end user without waiting for the entire frame to be processed. Thus, reducing the delay in waiting for the entire frame of video data provides improved real-time video communication.
摘要翻译：本发明是一种用于减少视频通信延迟的方法和系统，包括例如视频转码和多点多媒体会议中的连续存在。视频通信控制单元通过处理被称为“块”的少量宏块中的视频流来减少这种延迟，而不等待获得全帧的视频数据。相反，输入的视频流被转换成解码的块。这些解码的块被传送到输出模块，而不等待解码整个帧。输出模块中的编码器对已解码的块（也称为编码器块）进行编码，并将其传送到最终用户，而无需等待处理整个帧。因此，减少等待整个视频数据帧的延迟提供了改进的实时视频通信。

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.

摘要： A user can design their own custom composed view for a videoconference depending on the users' individualized needs. The view can include segments (windows) in which participating conferees' video images are presented and accessory elements such as window borders, text, icons, and the like. The content of the accessory elements can be linked to events within the conference or the content of other objects within the view. A custom composed view for a video conference can be designed off-line by a user, loaded into a videoconferencing device, and executed to generate the custom composed view. The videoconferencing device can synchronize the content of accessory elements with the content of other objects presented in the view.
