Abstract

PURPOSE:To detect the identifying information having the content of broadcasting succeeding, by providing the discrimination signal for the confirmation of CM broadcasting at the head of the CM identifying signal. CONSTITUTION:The reproducing signal from the tape decks 301, 302 for right (R), left/monaural (L/M) for dubbing mother tape is cut off for the frequencies 100Hz or less through HPFs 321, 322. This is recorded on the tape decks 341, 342. The reproducing signal of the tape deck 302 is branched and the synchronizing signal is picked up through the rectifying and smooth circuit 36. The output of the oscillation sources 401, 402, 403 of three waves f1, f2, f3 selected for 100Hz or less, except the vicinity of 50Hz, 60Hz at the synthesizer 44 provided between HPF 322 and amplifier 332 is coded by the digital information at the switches 411, 412, 413, and synthesized through BPFs 421, 422, 423. Thus, the CM identifying signal formed is received and the content of the succeeding broadcasting can be discriminated by the detection of the identifying signal consisting of f1, f2 and f3.
