介绍了以编解码器为基础的音视频信息跨网安全接入与控制系统,该系统使用双通道设计理念,在网络边界基于模拟信号实现音视频信息交换,基于RS232接口技术实现控制命令交换,数据交换为非IP方式,降低网络应用风险,保护网络安全。同时,该系统提高音视频跨网接入的实时性,为更好的实现音视频综合集成应用,提供一种有效的解决方案。
This paper introduces a dual-channel design concept based on codec, which is based on analog signal to realize the exchange of audio and video information at the network border. The exchange of control commands is based on the RS232 interface technology, Data exchange is non-IP, reducing the risk of network application and protecting network security. At the same time, the system improves the real-time performance of audio and video inter-network access and provides an effective solution for better integrated application of audio and video.
