Abstract:
1. Video apparatus with a first connector for outputting first RGB signals, with a second connector for receiving second RGB signals, and with an On-Screen Display circuit generating third RGB signals, wherein a RGB generator generates fourth RGB signals, a first RGB switch is connected to the second connector and to the On-Screen Display circuit for receiving respectively said second RGB signals and said third RGB signals, the first RGB switch outputs fifth RGB signals, in that a second RGB switch is connected to the first RGB switch and to the RGB generator for receiving respectively said fifth RGB signals and said fourth RGB signals, the second RGB switch outputs the first RGB signals, the first RGB switch is controlled by a first fast-blanking signal generated by the On-Screen Display circuit, a first OR-gate generates a second fast-blanking signal based on said first fast-blanking signal and on a fast-blinking signal of the second connector, and a second OR-gate generates a third fast-blanking signal based on said second fast-blinking signal and on a fast-blanking signal of the RGB generator.
