Japanese Patent JP2681918
Kind Code:
B2
Abstract:
PURPOSE:To avoid unpleasant noise from being heard by sending an audio signal through an FM signal system when a trouble takes place in a digital signal system so as to obtain voice by the FM signal system even if the trouble takes place in the digital signal system. CONSTITUTION:Audio signals L, R of a designated channel are decoded in case of the television mode and supplied to a headphone 207 through amplifiers 52L, 52R. In this case, if the signals L, R are in error, a signal A from a tuner 203 is extracted from a switch circuit 51 and the signal A is given to a headphone 207 through the amplifiers 52R, 52L. Thus, if a trouble takes place in the digital system, the voice is obtained from the FM signal system of the video signal system.
