Abstract

PURPOSE: To make it possible to remove surely FM audio signals which incline to mixture into video signals by sampling band components, where FM audio signals exist, from video signals and leading out the difference between the components above and adjacent scanning line components.
CONSTITUTION: Video signals demodulated by 5 in a video player are divided into two, and one and the other are supplied to video transmission system 6 and correction signal forming circuit 7 respectively. Here, circuit 7 is constituted by BPF 8 for a band where furthermore demodulated video signals are led and circuit 9 which takes the difference between the output of this filter and adjacent scanning components. Correction signals formed by circuit 7 are cancelled in respect to in-phase luminous components out of the output of BPF 8 and become only FM audio signal components As, and As can be led out easily because it has the phase shifted by 180° in the adjacent scanning line, and consequently, these led-out correction signals are applied to transmission system 6 to cancel FM audio signals components in them, and video signals where FM audio signals components are removed completely are led out from transmission system 6.
