Scart: Designates a connector variant on which all possible signals (see Signal) be transmitted. It can e.g. B. a transfer of CVBS (see CVBS), S-Video (see S-Video) and RGBsignals (see RGB) or any combination of these signals. In most cases, however, not all signals are wired. A SCARTConnection from a video recorder z. B. never an RGB signal, most likely it has an S-Video signal.
A CVBS signal and the lines for the two TonEvery device has channels. You still have to be careful with SCART cables, because there are cables where not all lines (21 pieces) are switched through, and there are also some where you have to switch between output and input, etc. Another problem with SCART is that you possibly. has several signals present. In a reasonable setup you should be able to set which of these signals you want to see.
