Abstract: A phase-locked loop (PLL) tuning controller monitors a voltage value of an automatic frequency control (AFC) signal, and detects a first frequency at which a first threshold voltage value accords with the AFC voltage value while varying an oscillation frequency of a local oscillator in either direction of frequency-increasing or frequency-decreasing in accordance with an AFC value when a synchronous signal of a broadcasting to be received is first detected. After then, a second frequency at which a second threshold voltage value having a value different from the first threshold value accords with the AFC voltage value while varying the oscillation frequency in a reversed direction for which the first frequency has been detected. Then the second frequency is locked as a center frequency of the broadcasting to be received. Accordingly, even if the AFC voltage level irregularly varies, the tuning frequency is fixed to the original center frequency of the broadcast to be received.

Abstract: An FF/REW control apparatus which performs high-speed FF/REW by simple control. Conventionally, if a hub diameter is discriminated, even though a user instructs execution of high-speed FF/REW, an operation mode cannot be immediately shifted to a high-speed FF/REW mode. Further, as a software sequence for hub discrimination is required, a ROM capacity for this purpose is required. The FF/REW control apparatus performs high-speed tape forward control for a thick hub and high-speed tape forward control for a thin hub. A system controller 20 calculates a value N representing the ratio between a rotational period of a take-up reel and that of a supply reel, and if the value N is other than values of a tape having the thick hub, immediately performs the high-speed tape forward control for the thin hub. Thus, the high-speed FF/REW can be quickly performed without direct discrimination of hub diameter, and software for this purpose is not necessary.

Abstract: The problem that a target stop position can not be searched accurately when videotaping is started midway on a blank videotape having no control signals thereon is solved as follows. In order to locate the target stop position while the counter display counts up or down as the tape is transported, the action to stop the tape is started when the counter display reads the same value as in the target stop position. Then, when the tape is reversed to offset the overrun due to inertia, the tape transport is controlled so that the reverse motion stops when a prescribed number of control signals have been detected and the display shows that the time required to reach the target stop position becomes a prescribed time or less. Consequently, the target stop position can be searched accurately, whether or not there are recorded control signals on the tape.
