6.6.2 Basic information on timing

Scanning with interlaced and non-interlaced procedures
There are two different scanning systems. They differ in the technology used to display the
image on the screen. TV signals, and monitors which are compatible with them, generally
use the interlaced procedure; computer signals, and monitors compatible with them, gener-
ally use the non-interlaced procedure. These two formats are not compatible; one of them
must first be converted before the signals can be processed together.
In the case of interlaced scanning, each image is divided into two separate fields. An image
therefore comprises two fields. An interlaced image is output on the screen in two scans.
The horizontal lines of the first field are scanned first, and then, again starting at the top of
the image, the horizontal lines of the second field are scanned between the first set of lines.
Field 1 consists of the lines 1 to 262 1/2, and field 2 of the lines 262 1/2 to 525. Only a few
lines are displayed at the top and bottom of each field.
