TV Display Chip

[dhouston]

I'll try to answer these questions.

1. It will be PAL first then NTSC next.
2. Currently needs it's own channel but I could easily offer an overlay option.
3. Expected cost. I notice the monochrome MAX video chip mentioned by someone else was around $9 in 1,000 off. I was considering under $10 for 1 off, not sure on quantity.

If you can offer NTSC and overlay for about $10, I'd certainly be interested and I think you would find a ready market. Please keep us informed of your progress.

most all current tv's here have composite input, some have rgb and s-video also. most will not display a pal signal. when you have some for ntsc put me down for a few.

Overlay seems to be something which is mainly used for security camera systems etc. TV signal overlay chips cost far more from what I can gather, although (I think) I've worked out how to do it with just the basic chip. What proportion of the demand would you expect to require overlay - say half?

This might just be my personal preference but I think more than half. Things like Caller ID, doorbell, car entering driveway and other messages should overlay whatever channel is currently selected so there's no additional action required by the user, while things like your power monitor can use their own channel.

I'd fork out the 10 -25 dollars for a kit / chip that alloud output to a tv monitor via simple coax / composite connection (ntsc? North America). Please let me know if you intend to offer such a thing..

See the April issue of Circuit Cellar Ink magazine, one chip, one capacitor, three resistors, and written in PicBasic Pro and Assembly.
