Subject: [oc] NTSC Video Encoding/Generation
Hey Mike,Until you get the NTSC video signal generating down you can get simple
converters (analog)RGB+HSYNC+VSYNC to NTSC like AD724? There are other
chips but you'll have to do a websearch. Best of all the AD724 can
generate S-Video for a better picture. Download the datasheet from
analog devices and you get get an idea of what is involved in RGB to
NTSC video.
