Abstract:
A system for generating a composite video signal having a composite video synchronization pulse in a composite synchronization signal time period and a composite video image signal in a composite active video time period, said system comprising:a video camera line;a video system controller for inserting onto said video camera line the composite video synchronization pulse during the composite synchronization signal time period of the composite video signal;a camera unit for receiving the composite video synchronization pulse on said video camera line, for generating a camera video image signal timed to the composite video synchronization pulse, and for inserting the camera video image signal onto said video camera line during the composite active video time period of the composite video signal as the composite video image signal and wherein said camera unit further comprises video synchronization remover to remove any composite synchronization pulse created by said camera unit; andwhereby said composite video signal comprises a composite video synch pulse from said video systems controller and a video image signal from said camera unit.
