We actually extract audio signals from video signals.

实际上我们从视频信号中提取了音频信号。

Headphones, firewire, USB 2 ports, analog and digital video output, modem, ethernet for communications. Really nice.

头戴式耳机、火线接口、USB 2接口、VGA和DVI视频信号接口、调制解调器、通讯网接口。真的常棒。

It's got firewire and USB 2, a modem, analog and digital video output, ethernet. And it's really tiny.

有火线和USB 2接口，一个调制解调器，VGA和DVI视频信号接口，网接口。真的常小巧。

Wait a minute, we just lost two screens-- what's going on?

等等 有两个视频信号丢失 怎么回事？

We'll have a live feed when he greets Weston.

To make things more confusing, some USB-C cables can be used with a second monitor, while others aren't capable of sending a video signal at all.

让人更加疑惑的是，一些 USB-C 数据线可与二台显示器一起使用，而其他数据线则完无法发送视频信号。

It sends a video signal-including temperature, depth and directional information-to an operator, who controls Trident remotely via an Internet connection, and sees what it sees through a virtual reality headset.

它能够将包括温度、深度方位信息通过视频信号的方式发送给操作人员，而操作人员可通过远程网络连接进行控制, 而且会一个虚拟现实耳机接收。

At least 200 companies now work on EW, says Mr Withington. The basic science of a front-line jammer is not complicated: a cheap metal box with aerials generates electromagnetic noise to block piloting signals or video feeds.

威辛顿说，现在至少有200家公司从事电子战。前线干扰器的基本原理并不复杂：一个带有天线的廉价金属盒会产生电磁噪声来阻挡驾驶信号或视频信号。
