摘要
为了解决传统视频会议存在的诸多问题,提出了一种基于嵌入式技术的网络视频会议系统。本系统以Linux系统和S3C2440控制器为核心,利用WIFI技术进行音频、视频数据传输,将UVC摄像头采集到的视频数据,音频采集芯片采集到的声音数据进行压缩并传输。接收端可接受连续帧图像以及同步的声音信息,并可以同步地将本地音频、视频数据传输给发送端。测试结果表明:该网络视频会议系统稳定可靠,音频、视频数据实时准确。
In order to solve the problems existing in traditional video conferencing,a kind of network video confer-ence system based on embedded technology is proposed.The system using Linux system and S3C2440 controller as the core,using WiFi technology for audio,video data transmission,UVC camera to capture video data,audio acquisition chip for acquisition to the voice data are compressed and transmitted. The receiving end can receive continuous frame images and audio information of the synchronization,and can synchronize the local audio and video data to the transmitting end. The results show that the video conference system is stable are reliable;audio and video da-ta are real-time and accurate.
