我使用了一个消费级摄像机，它使用复合（标准）视频线将输出发送到视频捕捉卡。

I used a consumer-grade camcorder that sent its output to the video capture card using a composite (standard) video cable.

一些视频卡和视频播放设备，包括新款苹果TV，甚至开始不支持VGA和复合输出，从长远来看，这将是个上升的趋势。

Some video CARDS and video playback devices, including the new Apple TV, don't even include VGA or composite outputs, and this will be an increasing trend looking forward.

利用视频捕捉卡将电视关节镜输出信号转变为数字信号，使用计算机记录和保存采集的图像。

The TV arthroscope signal is turned into digital video signal through a video capture card, and then the digital signal is recorded and stored through a computer.
