So I been doing some work with the TVout library.

It works fine, but I want to know how it works.

Can someone:

a) point me to a tutorial on how NTSC works

or

b) • tell me how the whole signal can be sent over only on line
    • What is the purpose of the sync and video lines converging (see schematic on above link)

Thanks!

I'm not kidding. If I am asking a question whose answer is found within the concerned product's datasheet, shame on me. If I am answering a similar question, shame on you!

FYI the vertical sync pulses in the link KE7GKP posted are not correct, they will work most of the time however(its what TVout does).
