1. A system, comprising:
- a first, computer system, including a video card, producing an output signal intended for driving a projector with an image, based on the control signal, and producing a second output signal, based on said control signal, indicative of a dim value of the output signal; and
a second system, receiving said output signal, and said dim value, and operating to dim an intensity value of the output signal based on said dim value, to produce an output signal to be projected.

Abstract
A stage lighting system with a digital and analog part. The digital part is used to form the image, which can be, for example, a full brightness image. The analog part is used to dim the image, and to carry out failsafe operation. If an error occurs in the digital part, then the analog part prevents the image from being shown.

8. A system, comprising:
-
a controller part, which produces video information indicative of an image to be displayed; and a bank of dimmer devices, controlled by said controlling part, and coupled to receive said video information and to provide a dimming function for said video information to produce another output signal indicative of a dimmed version of said image. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)

17. A system, comprising:
-
a first, controlling part, including a video card, producing an output signal indicative of an image, by drawing the output signal in the video card; and an external device, receiving information from said video card, and producing a first output for a monitor screen and a second output to be displayed, and monitoring for updates from said first controlling part, and preventing the output signal from being displayed on said display screen when said updates are not received for a specified time period. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A method, comprising:
- producing a digital representation of an image to be displayed on an external projector; and
carrying out an analog dimming of the image prior to display on said external projector.
- producing a digital representation of an image to be displayed on an external projector; and
-
25. A method, comprising:
-
producing a request for an output image at less than full output intensity;
drawing a full intensity output image in a video card; andcarrying out a dimming operation on said full intensity output image.

26. A system, comprising:
- an input for video signals;
a plurality of analog multipliers, coupled to receive said video signal, said plurality of analog multipliers including a first multiplier set which produces a first viewable output, and a second multiplier set which produces a second, monitor output,a processor, also having an input for a control signal and which controls said first multiplier set separately from said second multiplier set; and first and second video outputs, said first video output receiving an output from said first multipliers said, and said second video output receiving said output from said second multiplier set. - View Dependent Claims (27, 28, 29)
