Abstract

PURPOSE:To eliminate the effect of interference, by applying a signal from a synchronizing separation circuit to a clamp circuit through a clamp pulse generating circuit, to a gate circuit through a gate pulse generator and to a mixer through a synchronizing pulse generator. CONSTITUTION:A composite video signal applied from a video signal reproducer VSP to an input terminal 1 of a video signal recording and copying adaptor SPA, is added with an interference signal Ps of a specific mode to a given blanking period, and it is given from the input terminal 1 to a clamp circuit 2 and a synchronizing separation circuit 3. A gate circuit 6 is closed with a gate pulse given from a gate pulse generator 4 at the horizontal synchronizing signal Ph to which an interference signal Ps is added in the composite synchronizing signal, to provide the signal where the horizontal synchronizing signal Ph and the interference signal Ps added to it are rejected.
