Types of Audio and Video Cables for Digital Video Recording
There are many types of Audio and Video Cables available for use with Digital Video Recorders, DVD Recorders and PC products. Below is an overview of audio and video cables and some common cables you will see when hooking up a DVR, DVD Recorder or connecting a peripheral to a computer. The Insides of a cable There are three main parts of a cable which affect signal quality: the conductor, the shielding, and the connector. The conductor is the part of the cable through which the signal actually passes. Since the conductor is basically a wire which can act as an antenna to receive radio frequency interference (RFI) and electromagnetic interference (EMI), a good cable also includes some kind of shielding, to filter out these potential sources of noise. The connector is the part of the cable that actually comes into contact with your equipment. Analog Audio cables RCA connections are the standard means of passing analog line-level audio signals between components.
