that provides at least 256 simultaneous colors and a screen
resolution of 1024 x 768 pixels.
Vertical Blanking Interval (VBI)
The time it takes the beam to fly back to the top of the screen in
order to retrace the opposite field (odd or even). VBI is in the order
of 20 TV lines. Teletext information is transmitted over 4 of these
lines (lines 14-17).
