PURPOSE:To record automatically desired programs and reproduce them by providing the first and the second means, which detect the coincidence between program start and end discriminatint codes and discriminating code obtained in the receiver side, and a counter which counts the elapsed time between both detection outputs. CONSTITUTION:The demodulated output demodulated by a tuner 2 is not only inputted to a sound recorder 3 and a program discriminating signal detecting circuit 4 but also outputted to the external. Program start and end discriminating codes superposed to a prt of a carrier wave or an audio band are detected by the circuit 4 and are inputted to a coincidence detecting circuit 5. The coincidence between outputs of a program start code pattern circuit 6 connected to a program selecting switch 8 and a program ene code pattern circuit 7 and program start and end discriminating codes detected by circuit 4 is detected by the circuit 5. The coincidence detection output is processed by FF circuits 10 and 12, etc. and is applied to a cpunting circuit 13. The elapsed time between detected start and end codes is counted by the circuit 13, and a program is recorded automatically. |
