A video signal receiver has a first output terminal (3) at which just one chromatic frame-blanking synchronizing signal (FBAS) or one frame-blanking synchronizing signal with a chromatic signal can be picked up and has a second output terminal (5) at which the color signals (R, G, B) and the corresponding synchronizing signals are provided. Video recorders normally utilize just one frame-blanking synchronizing signal with corresponding chromatic information and can be connected to the first output terminal (3). Television sets (6) normally utilize RGB signals as well and can be connected to the second output terminal (5). On the basis of an identification generated on the transmission side, a control device can block the signal to the video recorder at the first output terminal (3). This makes it possible to present a coded transmission on the television set (6) but block recording by the video recorder (4). |
