SELECTIVE RECORDING SYSTEM OF BROADCAST PROGRAM |
摘要 |
<p>PURPOSE:To attain recording capable of selecting automatically a broadcast program by inserting at least two kinds of frequencies in a frequency difference possible for discrimination by an audible frequency to a non-sound broadcast band to drive and control a pause mechanism of recording side. CONSTITUTION:Various control signals are transmitted in the non-sound broadcast band at the broadcast side. The broadcast radio wave is received on a receiver 6 via a receiving antenna 5 and broadcast from a speaker 8 via an amplifier 7. The control signals are transmitted to a signal discriminating circuit 10 via a preamplifier 9 and supplied to a control circuit 12 by a selecting means and a switching means 11 so as to be suitable for the control mode by discrimination and selection. The circuit 12 drives the pause mechanism drive means 14 of a recorder by an input signal for operating on/off and records the content of the broadcast program automatically with selection.</p> |
