What is Synchronizing System?

As transmitter is synchronizing with receiver, signal synchronization must be done. HSYNC (horizontal sync) signal controls horizontal scanning and VSYNC (vertical sync) controls vertical scanning.

Sync system involves the three kinds below:

• 1.Internal synchronization: It means that internal synchronization signal of camera creates synchronization signal of electrocircuit.
• 2.External synchronization: It means that an external generator of synchronization signal attributes synchronization signals to external synchronization for inputting.
• 3.Power（line-lock）synchronization: It adopts cyclic wave of AC current of camera to finish VD (vertical drive) synchronization.
