Abstract
PURPOSE: To display whether or not a monitor television receiver is operating normally and what input is being monitored by projecting one of colors constituting its color screen even if no monitor input signal arrives at the time of selectively monitoring a plural number of inputs.
CONSTITUTION: One of signals from VTRs 1a and 1b, and camera 1c is applied to chrominance demodulator circuits 9a, 9b and 9c by way of luminance-signal amplifier circuit 6 and color signal processing circuit 8. A luminance signal and chrominance demodulated signal are mixed together by color drive circuits 7a, 7b and 7c, thereby driving picture tube 20. When there is no input signal, the series circuit composed of synchronizing separator circuit 23, integrating circuit 24 and inverter 25 detects it and its output drives one of color driver circuits via switch 26 interlocking with input-signal selection switch 3, so that a specific color will be displayed on the picture tube.
