A OUTPUT APPARATUS OF MULTI SOUND SIGNAL IN USING VFD FOR TELEVISION

摘要

PURPOSE: An apparatus for outputting multi-sound signals in using VFD(Vacuum Fluorescent Display) for a television is provided to selectively output the multi-sound signals outputted through a speaker and a headphone in the television through the VFD. CONSTITUTION: A sound demodulator extracts low frequency sound signals from sound signals including a foreign language signal and an identification signal. An amplifier amplifies the low frequency sound signals. An identification signal detector(260) detects a mixed identification signal in signals outputted from the sound demodulator. A sound identifying device(210) converts the sound signals amplified in the amplifier into digital signals, by adjusting the low frequency sound signals to a font of the digital signals. A VFD(Vacuum Fluorescent Display) controller(220) receives the digital-converted sound signals and outputs an anode driving signal and a grid driving signal to a VFD(230). The VFD(230) outputs the digital-converted sound signals on a VFD fluorescent screen. A controller transmits control signals to the identification signal detector(260), the sound identifying device(210) and the VFD controller(220), and controls the VFD output of the sound signals.
