Hey Guys,

Does anyone have a general idea of the circuit needed to generate a composite video signal?

There are chips that generate composit video for you. Is that what you mean? There are some that are used in NTSC test instruments too, with built-in test patterns.

What is your application? Generate composite video from what? R-B-B-syncs?

Yes. To be more specific, I need a color composite video signal. I would like to use a television for a display for a microprocessor system that I am building. I could use a normal computer monitor but I would like to experiment with a television for a display first.

And your TV has a baseband composite video input? What is the connector for it?

There's an application note from Maxim at the bottom of this wikipedia article, so it looks like Maxim may make an Ic that you can use:
