I just looked that the price of the encoder chip. I didn't realize it was so cheap.Anyways, I'd still like to look into alternate ways of doing the color. Although, I don't know much about oscillators.Another thing I'd like is to do a more flexible version of the current TVOut that works on composite or SVideo. Greyscale or monochrome with higher resolution tile and sprite graphics. Then if I can figure out the color later it'll fit into that library.EDIT: The only unknown at this point is about Voltage Controlled Oscillators or something like that. I don't know much about intricate electronics like this. Know any good tutorials or guides?EDIT2: There's also the option of doing AM on two 3.5...MHz oscillators with one being 90 out of phase. This would mean we're doing RGB colorspace again (or it would take additional processing for HSV). The reason this might be easier is if the appropriate oscillators are easier/cheaper to obtain and calibrate than it is to build/buy a VCO that can do 3.0... to 4.0...MHz. As I said, I don't know much about such intricate electronics. Nor how to synchronise them as such.Also, according the picture in this: http://en.wikipedia.org/wiki/NTSC#Transmission_modulation_schemeThe color band can vary by half a MHz. Which is why I said 3-4MHz range for the VFO.
