    • PROBLEM TO BE SOLVED: To provide a technique in which a TS signal is smoothly transferred to a transmitter from an encoder.SOLUTION: An oscillator 28 outputs a reference clock. A multiplexing part 24, on the basis of the reference clock, generates a TS signal by multiplexing data. A transmission buffer part 26 outputs the generated TS signal to a broadcast device 14. A reception tuner 34 receives a radio signal which is transmitted from the broadcast device 14 and generated from the TS signal on the basis of the reference clock in the broadcast device 14. A control part 36, on the basis of the TS signal extracted from the radio signal and the TS signal outputted from the transmission buffer part 26, estimates a difference between the reference clock from the oscillator 28 and the reference clock in the broadcast device 14, and controls frequency of the reference clock outputted from the oscillator 28 on the basis of the estimated difference.

    • PROBLEM TO BE SOLVED: To inexpensively acquire a synchronizing generator which allows synchronization to be instantaneously established and a synchronous condition to be held with high precision for a relatively long time. SOLUTION: This synchronizing generator includes at least a counter 22 with set or reset, and a synchronous detection means 24. In the synchronous detection means 24, the timing of a rising point, a falling point, or a zero crossing point of a synchronous input signal is detected. At the timing, the counter 22 is set or reset. This allows synchronization with a synchronous input signal to be instantaneously established, and when the synchronous input signal is paused or stopped, or after it is removed, the synchronous condition to be held with high precision for a relatively long time.
