S7200 TV Signal Analyzer Operation Manual
The analog video signal includes synchronization pulses that control the scanning
line by line from left to right and field by field from top to bottom. The pulses that
control the line-by-line scanning are called the horizontal synchronization pulses
(H-Sync). The pulses that control the vertical scanning are called the vertical
synchronization pulses (V-Sync).
Two interlaced fields compose a complete frame. The first field, called the odd
field, scans the odd lines of the video image. The second field, called the even
field, scans the even lines of the video image. The process repeats for every frame.
