Hi,

I am looking for a FPGA based video prototype board with
the following components:

1 Video decoder for 1 color composite Video in
1 FPGA preferably Altera
About 1 Megabyte SRAM
Some spare IO pins
1 Color composite video out

The boards I have found are too expensive
and have a lot of other hardware like multiple FPGAs or DSPs,
which I don't need.

Someone an idea?

Thanks!

Markus

Hi Karl,

thanks for the hint, I didn't find this board on the altera website yet.

Unfortunately, it has no composite video output, but vga output.
For composite video output, you usually need a video encoder chip.

I think that this can't be used as a composite color video (FBAS) output.

But if I don't find a board with video out, I will take this one
and add a video encoder on a separate board.

Thanks!

What makes you think that you could not use one of the RGB 10bit DA channels

for FBAS out (composite?) composite is only 1 Vpp (in Europe).
On opencores.org IIRC there is even a PAL modulator.
Not sure if it will fit with that clock.
