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.
