摘要
重点介绍了基于3星ARM控制器S3C2440和linux-2.6.22操作系统的数字可视楼宇对讲系统的软硬件设计与实现。该系统通过局域网实现楼宇中各嵌入式终端机互连,采用RTP协议进行语音及视频流传输,使用Mediastreamer2流媒体处理框架对语音视频流进行传输、处理、保存、播放,实现嵌入式终端可视对讲和监控功能。
This paper focuses on design and implementation of digital visual building intercom system based on the Samsung ARM controller S3C2440 and linux-2. 6. 22 operating system. Embeded terminals of this system ac.hieve interconneetion through LAN. RTP protocol is adopted to transmit audio and video streams. Mediastreamer2 library, a media stream processing framework, is used for audio and video stream transmission, processing, storage, and playback, to achieve the video intercom and monitoring.
