摘要
在分析多窗口模式视频会议系统体系结构及其对网络带宽占用情况的基础上,结合现实会议中语音和视频的关系,提出个人视角模式视频会议的概念及其体系结构,并深入分析该模式与多窗口模式相比在带宽利用上的优势,提出利用静音检测技术实现语音数据和视频数据的同步传输,在局域网环境中实现了个人视角视频会议系统。
Based on an analysis of multi - windows video conference system, the utilization of bandwidth and the relations between video and voice in a real conference, a new concept about the Personal View Video Conference is proposed. Its advantage in bandwidth utilization is carefully analyzed. VAD （voice activity detect） technology is proposed to guarantee the synchronization of audio and video transfer.
