How to Convert Coaxial Cable to a RCA Demodulator
Coaxial cable is an older style of audio/video cable commonly used to transmit a television programming signal to a TV. Converting the coaxial signal to an RCA demodulator expands the connection option for other electronic devices that are more likely to be equipped with RCA-type composite audio-video jacks. An RCA demodulator is available at most electronics stores.

Tips & Warnings
A VCR can be substituted for a demodulator if the goal is to convert a coaxial output to an RCA input. Connect the coaxial cable to the "RF IN" jack on the VCR, then attach a set of RCA composite cables to the "Output" jacks on the VCR by matching the plug colors to the jacks.
Unplug electronic devices from the electricity while connecting AV cables.
