摘 要
本课题主要研究短距离内通过无线信号网络进行视频信号传输的视频通信
网络。主要可应用于安防、监控、控制、对讲等领域。本课题采用 MAX7456 视
频叠加器件实现 OSD(On Screen Display)技术,通过 TX24017 视音频发射模块与
RX2188 视音频接收模块组成无线信号传输系统,实现了短距离内的无线信号视
频通信。

Abstract: The main research topics within a short distance video signal transmission
network via radio signals video communications network. It can be mainly used in
security, monitoring, control, intercom and other fields. This paper uses MAX7456
video overlay devices implement OSD (On Screen Display) technology, consisting of
a wireless signal transmission system and RX2188 receiver module by TX24017
audio visual audio transmitter module, wireless video communication signal within a
short distance.
