interlace scanning

Quick Reference

In the majority of standard definition television systems, a process where all the odd lines of a television picture are scanned first—from the top left to the bottom right of the screen—and then the electron beam ‘flies back’ and scans all the even lines. Interlace scanning is a way of evening out the picture brightness and reducing flicker.
