摘要： Disclosed herein is a method and apparatus for mixing compressed video useable in a videoconferencing environment having a plurality of endpoint users. Through the use of the method and apparatus, each endpoint can receive a unique layout displaying some subset of the users at the endpoints. Input streams from each endpoint are uncompressed, resized, and scaled to fit the segment in the layout for particular endpoints, and then encoded (or compressed) by a sub-encoder into a sub-encoded stream according to the compression parameters. Each sub-encoded streams is further encoded and associated with a position in the layout. Different layouts may be sent to different conferees, and different compression standards may be used for each endpoint.

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。
