video waveform

The main components of the video waveform are the active video portion and the horizontal blanking portion. Certain video waveforms carry information during the horizontal blanking interval.

Figure Gl-8 and Figure Gl-9 diagram a typical red or blue signal, which carries no information during the horizontal blanking interval, and a typical Y or green-plus-sync signal, which carries a sync pulse.

Figure Gl-10 and Figure Gl-11 show the video waveform and its components for composite video in more detail. The figures show the composite video waveform with and without setup, respectively.

Figure Gl-10 shows a composite video signal with setup.
