Scart cables: How do they work?
Scart cables have become the common connector for audiovisual equipment and have become the standard connector for some applications. Different Pin configurations exist in Scart, depending upon the configuration obtainable in your video device. Sometimes the configuration could be chosen by simply changing a software setting.
Scart is a bi-directional connector as far as standard composite video and analog audio signals are concerned featuring use for a Pay TV and it is used for decoding a tele-text. But now it is being applied to set-top boxes, which is a device, connected between a TV set and an external device and is used to decode the signal and send it to the TV for display. A TV sends its antenna video and audio signals to Scart sockets all the time and receives back these signals and displays them reproducing the audio and video allowing the concept of transparent set-top boxes having no tuner by just hooking on the TV and pre-process the television signals.
In a simple explanation Scart cables enable a device to command a TV set to switch between signals, in order that overlays in the TV picture image could be created and A VCR would have its power coming on as soon as the cassette is inserted and the TV set would transform into video mode and then start playing immediately if the cassette’s write protection tab is absent and while switching it off, the VCR will send a signal to the TV set to power off.
