Can anyone help me get my head around making my own B/W NTSC signal? I haven't found much that's very informative on the web. It might be that I don't know enough about what I'm interested in to know what to search for. Not interested in PAL, just NTSC. And yes, I've read the wiki entry.
The part that's confusing me a bit is how the whole horizontal and vertical sync thing works in the timing. I'm having trouble finding a timing diagram that makes intrinsic sense or otherwise is properly documented.
How much leeway is there for accommodating certain parts of the protocol? For instance, I gather in PAL each horizontal scan line is exactly 64us, but in NTSC, each scan line is just slightly less than 64us. Would it be a big deal if I just round down to 63us, or will that just clip the right-side of the image a bit?
