DEF

The downward movement of the scanning beam from top to bottom of the picture being televised.

CONT

When the beam has returned to the left side, its vertical position is lowered so that the beam will scan the next line down and not repeat the same line. This is accomplished by the vertical scanning motion of the beam, which is provided in addition to horizontal scanning. As a result of the vertical scanning, all the horizontal lines slope downward slightly from top to bottom. When the beam is at the bottom, vertical retrace returns the beam to the top to start the scanning sequence again.

OBS

vertical scanning; vertical sweep: terms officially approved by the Lexicon Project Committee (New Brunswick).
