When a timer reservation is made to record a Western movie program between 9.00 and PM11.00, if the broadcast time of the program before the reserved program, for example, baseball broadcast is extended by 15 minutes, the movie program actually recorded will be displayed. There was a drawback that the recording time was shortened by 15 minutes. Therefore, if the broadcast start time of the Western picture program to be reserved and recorded is delayed, the reservation time must be manually changed.
また、本来タイマー予約録画を行なう場合、視聴者は不

Receiving means having pilot signal detecting means for detecting a bilingual broadcasting pilot signal included in a bilingual broadcasting in a television audio signal, and recording means for recording the television signal obtained from the receiving means on a tape. At a preset date and time, a recording reservation means for driving the receiving means and the recording means to record a desired program, and a first time which is a recording start time set by the recording reservation means Recording is started, and a bilingual broadcast is received by the output of the pilot signal detection means at a second time after a predetermined time has elapsed from the first time. If it is determined that the recording start is stopped, the recording is stopped to rewind the tape to the initial position, and the recording reservation means is controlled to set the recording start time later than the second time. The control means for setting the time of 3 is provided.

記憶せしめる。After the timer reservation is set, the data from the clock circuit (5) representing the real time and the data of the earliest start time among the reservation contents stored in the reservation storage circuit (3) are the reservation execution circuit.
It is compared in (4), and if the data match, the recording signal (R) is supplied to the system controller (15), the channel selection circuit (16) and the 5-minute timer circuit (6). When the channel selection circuit (16) receives the recording signal (R), it controls the tuner (10) to receive a channel that matches the reservation content. When the system controller (15) receives the recording signal (R), the V.V. The S recording circuit (12) is controlled to record video and audio signals on the magnetic tape (17) by the circuit (12). Also,
The system controller (15) controls various mechanisms such as the tape running system (18) and also causes the reel counter value at the start of recording to be latched from the tape counter circuit (19) to the latch circuit (20) and also to the memory circuit. Remember in (21).

る。The 5 minute timer circuit (6) in the microcomputer (2) determines the timer output (T) 5 minutes after receiving the recording signal.
Supply to (7). This discrimination circuit (7) outputs a timer (T)
At the time of receiving the discrimination signal (P) from the voice / discrimination circuit (12)
Is output. Voice / discrimination circuit (1
When the discrimination signal (P) is output from 2), the discrimination circuit
(7) is a control signal that causes the reservation execution circuit (4) to continue the reserved recording.
(C 1 ) is supplied, the reservation execution circuit (4) is a reservation storage circuit.
The reserved recording operation proceeds according to the reservation information stored in (3), but when the discrimination circuit (7) receives the timer output (T), the discrimination signal (P) is output from the voice / discrimination circuit (14). If not, the discrimination circuit (7) is the system control circuit.
A control signal (C 2 ) is supplied to (15) and the 15-minute extension (3c) of the reservation storage circuit (3). When the system controller (15) receives the control signal (C 2 ), it supplies the Rew signal (Rew) to the reel drive circuit (22), so that the drive circuit (22) drives the reel base (23) to record. Performs tape rewinding operation.
At this time, the PG signal obtained from the reel stand (23) is detected by the rotation detection circuit (24), the number of rotations of the reel stand is counted by the counter (19), and this count value is one of the coincidence comparison circuits (25). Given as input. Since the tape count value at the start of recording is given from the memory circuit (21) to the other input of the coincidence comparison circuit (25),
The coincidence comparison circuit (25) outputs a coincidence signal to the system controller (15) when they coincide with each other. System controller
When the coincidence signal is received, (15) cuts off the supply of the Rew signal (Rew) to the reel drive circuit (22) to stop the drive of the reel stand. As a result, the position of the recording tape (17) can be aligned with the same position (initial position) as when recording started.
一方、１５分延長部(3c)は判別回路(7)から制御信号
(C2)を受けると開始時刻設定部(3a)に最初に記憶された
録画開始時刻を１５分遅らせる。尚、本実施例では録画
時間で設定しているので、破線の信号(C3)で録画終了時
刻の時間を遅らせる必要はないが、録画終了時刻で設定
するＶＴＲでは録画終了時刻設定部を設けて、録画終了
時刻を１５分延長させるようにすればよい。On the other hand, the 15-minute extension section (3c) receives the control signal from the discrimination circuit (7).
When (C 2 ) is received, the recording start time initially stored in the start time setting section (3a) is delayed by 15 minutes. Since the recording time is set in this embodiment, it is not necessary to delay the recording end time with the broken line signal (C 3 ), but the VTR set at the recording end time is provided with the recording end time setting section. Then, the recording end time may be extended by 15 minutes.
このようにして、１５分間録画開始時刻が延長設定され
た後、１５分間経過すると上述の動作を再び繰り返すこ
とになる。In this way, after the recording start time has been extended for 15 minutes and 15 minutes have elapsed, the above operation is repeated.
以上の構成のＶＴＲでは、放送予定時刻が例えば９：０

る。In the VTR having the above configuration, the scheduled broadcast time is, for example, 9: 0
Even if a Western picture program that is broadcast for 0 to 2 hours is started at 9:15 due to an extension of the baseball program that was broadcast before that, since bilingual broadcasting is not detected as of 9:05, Since the recording is stopped, the tape is rewound to the initial position, and the reserved recording start time is set to 9:15, it is possible to surely record all the programs to be reserved recorded. In addition, if the extended timer button (7) is turned off at the time of timer reservation,
Recording is started from the reserved recording start time (9:00) even though the baseball broadcast is extended as in the conventional case.
(ト) 発明の効果 以上の通り本発明に依れば、タイマー予約録画したい番

実に記録できる。(G) Effect of the Invention As described above, according to the present invention, when the program desired to be timer-recorded is a bilingual program such as a Western picture program, even if the broadcast time of the program before the reserved program is extended, Detect
Since the recording start time of the program to be recorded is automatically shifted by the extended time of the previous program, the scheduled recording program can be surely recorded.
