NTSC to VGA?

Oldbitcollector (Jeff)

I know there are a number of products (priced from $40-$99) which will
convert NTSC video output to display on a VGA monitor. (scan conversion)

Does anyone know of any chips/circuits which do this that could be incorporated
into a Propeller protoboard design? In other words, has anyone gotten this down
to a science without having to order an additional box and wall wort solution?

Thanks
OBC

Why not just have the Propeller generate VGA? Is the problem too many I/O pins or not enough memory?

An NTSC to VGA scan converter is just a complex piece of machinery whether you build it yourself on a Protoboard or buy a ready-to-go unit. You basically need an NTSC display that writes to a pixel frame buffer (like 640 x 420), then a VGA display at that resolution. You need at least a 32K buffer as well.

I think OBC is after a prop object to decode a composite video (NTSC) signal input. Not sure if this is doable or not as I do not know enough about the video signal and counters.
