The system is Power Source interworking system as VTR which connects an image input port of a TV having BS with an integrating circuit (20) and detection circuit of synchronization (10) for detecting synchronization from VTR with BS receiver control input line of a micom (2). The detection circuit of synchronization comprises capacitors (C1,C2,C3) for direct current blocking, resistors (R1-R8), and transistors (Q1-Q3). And the integrating circuit consists of a resistor and a capacitor.
