I need info on how to generate a NTSC signal using VHDL (or verilog) and a fpga.

I have been frantically looking all over the Internet but can't find a single example. I am familiar with VHDL but not with NTSC at all.

Are there any good internet resources out there on NTSC or good books you can recommend that don't require a PhD?

Any cores or examples in VHDL (or verilog) floating around out there?

Any tips at all?

Thanks so much!

You'll probably need a 14.31818 MHz clock (4 x the subcarrier frequency). You'll also need a DAC, but this may be as simple as a few resistors if you don't need a good picture quality.

Regards, Allan.
