IPC: H04N7/167
Filed: 1986-06-20
Abstract: PURPOSE:To disable the generation of a gain control signal based upon only the AM detection of a sound signal and to prevent personal transmission/ reception from being tapped by a third person by discriminating the compressed portions of horizontal and vertical synchronizing signals by timing pulse width. CONSTITUTION:A sound signal B out of a TV signal supplied to an input terminal 1 is frequency-separated from a video signal A and detected by an AM detecting circuit 4. The output C of the circuit 4 is supplied to a pulse width modulating circuit 5, a pulse width detecting circuit 6 and a reset terminal R of an FF 7. An OR gate 8 finds out OR operation between the output D of the circuit 5 and the output E of the FF 7 and outputs a signal F. Since the signal F is turned to the H level at the time portions T1, T2 of the signal A, the signal A is supplied to a gain variable amplifier 2 to increase the gain only for the H level period. Consequently, the TV signal existing before the level compression can be restored from the signal obtained from the terminal 1.
