Interlaced scanning, also known as interline scanning, is a method of displaying visual information on a screen by alternating the display of even and odd lines. It has been used in television broadcasting for many years, but has largely been replaced by progressive scanning in recent times. Other possible synonyms for interlaced scanning could include "line scanning," "field-based scanning," or simply "interlacing." Each term refers to a similar method of displaying visual information that involves alternating lines or fields of information on the screen to create a complete image. While these methods have become less common over time, they remain important historically and in certain specialized applications.
