Is it possible to control LED lights with a DVD player output?

[kikkoman1]

Hello,

I am working on a sound/light installation at the moment and was hoping that someone on here might be able to help me with a question i have.

I would like to use the composite output from a DVD player to control the intensity and hue of LED light (or 3 (RGB) if need be). So essentially the LED will act in the same way as a projector/television would however is smaller and cheaper :).

I'm not sure if there i something like this on the market or if this is even achievable.

Any help would be much appreciated.

A frame of video contains all kinds of different colors and intensities throughout -- how are you going to decide which of the millions of colors present in the image will end up on your tri-color LED?

Hi Warren

The source footage has all equal colour and intensity across the frame, but changes as time progresses. Thus each pixel is identical at points throughout.

You would need to decode the composite output from the DVD player into RGB outputs.
You could connect your display to the monitor output of a computer.
Or scavenge some of the circuitry from an old TV.
I don't know if a standalone composite to RGB converter is available, perhaps.

I have done something similar before. Use Max MSP with Jitter, you'll need a video ADC if your using a standalone DVD player, the output interface I used was an Arduino board.
