摘　　要：2021年,某政务单位在升级视频会议系统时采用了Dante网络音频传输技术,提供了一种整体解决方案。该技术在以太网(Ethernet)网络中能够同时发送和接收多个音频通道。Dante音频传输无杂音、传输速度快、精度高且成本低,点对点传输基本接近于零延迟,通常可以通过双绞网线替代音频线路,节省成本。同时,Dante技术可以通过网络层以网际协议(Internet Protocol,IP)的形式实现音频通信,使得音频数据与会议相关数字信号互不干扰,兼容不同型号的音频设备。通过Dante网络音频传输技术的实施,解决了音频在项目实施期间的很多难题。In 2021,a government unit adopted Dante network audio transmission technology when upgrading the video conference system,which provided an overall solution.This technology can send and receive multiple audio channels at the same time in the Ethernet network.Dante audio transmission is noiseless,fast,high in accuracy and low in cost,point-to-point transmission is almost zero in delay.audio lines can usually be replaced by twisted pair cables,saving costs.At the same time,Dante technology can realize audio communication in the form of Internet Protocol(IP)through the network layer,so that audio data and conference-related digital signals do not interfere with each other and are compatible with different types of audio equipment.Through the implementation of Dante network audio transmission technology,many difficult problems of audio during the project implementation have been solved.
