1.1A Word on Sync Signals

All video signals received by a monitor carry with them synchronization information. Whether they are analog signals (Composite, Y/C, Component and RGB) or digital (SDI, etc.), the synchronization signals are needed for proper alignment of the image on the screen. In most video formats, there are two types of sync signals: horizontal sync and vertical sync. Many problems, though sync related, are sometimes misinterpreted, and other components of the signals are blamed instead.

1.1.1Horizontal Sync

The horizontal sync in a composite video signal (often referred to as line sync) is a short, negatively directed pulse, found at the beginning of each scan line of the monitor (see Figure 1). Basically, this pulse “tells” the monitor: “be prepared, a line of data is coming”. Horizontal sync resides in the blanking area (the unseen part of the signal), and so is not visible on the screen. The number of line sync pulses equals the number of video lines.
