Abstract

PURPOSE:To surely record all the programs that are reserved to be recorded by detecting that the starting time of a reserved program which is a bilingual broadcasting program is delayed, then rewinding a recording tape to an initial position and performing new reservation by a timer when such a delay occurs. CONSTITUTION:The tape recorder is provided with a reception means having a pilot signal detection means 14 for detecting a pilot signal for bilingual broadcasting, a recording means 12 for a television signal and a recording reservation means 1 for recording the desired program at the date and hour previously set. When it is a 1st set reserved time, recording is started and when it is discriminated with the aid of an output from a pilot signal detection means 14 that the bilingual broadcasting is not received at a 2nd time which is after the lapse of specified time from the 1st time, recording is stopped and the tape is rewound to the initial position by controlling the recording means 12. At the same time, the recording reservation means 1 is controlled and a control means 2 sets a recording starting time at a 3rd time which is later than the 2nd time. Thus, the program which is intended to be recorded is surely recorded.

Description

[Detailed description of the invention] It relates to a video recorder (VTR).

(b) Conventional technology In recent years, various functions have been added to VTRs.
For example, JP-A-60-149277 (HO4N
5/91) proposes a VTR equipped with a system for recording programs with commercials automatically cut out.

(c) Problems to be solved by the invention By the way, in the conventional VTR, as shown in FIG.
9. If you make a timer reservation to record a Western movie program between OO and PM 11.00, and the broadcast time of the program before the reserved program, for example, a baseball broadcast, is extended by 15 minutes, the actual recording time of the Western movie program will change. had the disadvantage that it was 15 minutes shorter. Therefore, if the broadcast start time of a Western movie program for which the user is scheduled to record is delayed, the reserved time must be changed manually.

Additionally, when timer-scheduled recording is performed, since the viewer is not present, it is possible to change the reserved time by using the telephone reservation method, but even in that case, the program before the reserved program will be recorded. You should know that the broadcast time has been extended.

Therefore, the present invention aims to solve such disadvantages.

(d) Means for Solving the Problems The present invention focuses on the fact that many Western movie programs currently being broadcast are broadcast in two languages, and baseball broadcasts are broadcast in stereo or monaural. Receiving means having a pilot signal detecting means for detecting a pilot signal for bilingual Japanese broadcasting included in a television audio signal during bilingual Japanese broadcasting in a recorder, and a recording means for recording the television signal obtained from the receiving means on a tape. and recording reservation means for driving the receiving means and recording means to record a desired program at a preset date and time, and a first time that is the recording start time set by the recording reservation means. Then, recording is started, and when it is determined at a second time after a predetermined time has elapsed from the first time that the dual language broadcasting is not being received by the output of the pilot signal detection means, the recording means is controlled. control means for stopping recording and rewinding the tape to an initial position, and controlling the recording reservation means to set the recording start time to a third time later than the second time.

(e) Effect: With the above configuration, if the broadcast of the program before the reserved program (Dual Korean Broadcasting) is extended and the broadcast start time of the reserved program is delayed, this will be detected and recorded. rewind the tape,
Make a new timer reservation.

(F) Example Hereinafter, an example of the present invention will be described with reference to FIG.

FIG. 1 shows a block diagram of a VTR embodying the present invention. When making a timer reservation, the timer microcomputer (microcomputer) (
2) Enter the broadcast date, broadcast channel, recording start time, recording time, etc. of the program to be reserved. Said microcomputer (2)
When expressed in terms of hardware, as shown in the figure, the reserved memory circuit (
3), consists of a reservation execution circuit (4), a clock B (5), a 5-minute timer circuit (6), and a discrimination circuit (7), and the reservation storage circuit (3) further includes a start time setting section (3a), It consists of a recording time setting section (3b) and a 15 minute extension section (3c). The broadcast date, broadcast channel, and recording start time data input from the reservation button (1) are sent to the start time setting section (3a).
The recording time data is stored in the recording time setting section (3).
b).

If it is predicted that the broadcast time of the program to be broadcast before the reserved program will be extended, press the extension timer button (7).
When turned on, that information is also stored in the storage circuit (3). Further, the operation status and setting contents at this time are displayed on the display section (8) by output from the microcomputer (2).

On the other hand, the RF signal received by the antenna (9) is converted into a signal multiplied by the IF selected by the tuner (lO).
) via ■, S recording circuit (video/audio recording circuit) (
+21 is supplied. On the other hand, the SIF signal (audio intermediate frequency signal) output from the tuner (101) is output from the SIF circuit (
13) and is supplied to the above-mentioned (1) and S recording circuit (12) via the audio/discrimination circuit (14). Further, the voice/discrimination circuit (14) detects 9 in the voice signal from the SIF circuit (13).
22.58. The presence or absence of a pilot signal for biloft Japanese language broadcasting is detected, and when the biloft signal is detected, a discrimination signal (P) is supplied to a discrimination circuit (7) of a microcomputer (2).

After setting the timer reservation, the clock circuit (5) that shows the real time
The reservation execution circuit (4) compares the data from and the data of the earliest start time among the reservation contents stored in the reservation storage circuit (3), and if the data match, the recording signal (R ) is supplied to the system controller (15), the channel selection circuit (also 1), 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 the channel that matches the reservation contents. The system controller (1
5) receives the recording signal <R), ■, S recording circuit (1
2), and the magnetic tape (1) is controlled by the circuit (12).
7) Record video and audio signals. Further, the system controller (15) also controls various mechanisms such as the tape running system (18), and also causes the number counter value at the start of recording to be latched from the tape counter circuit (19) to the launch circuit (20). The data is stored in the memory circuit (21).

The 5-minute timer circuit (6) in the microcomputer (2) supplies a tie 1°-output (T) to the discrimination circuit (7) after 5 minutes have elapsed since receiving the recording signal. When this discrimination circuit (7) receives the timer output (T), the /discrimination circuit (12)
If the determination signal (P) is output from the reservation execution circuit (4
), the reservation execution circuit (4) proceeds with the reservation recording operation according to the reservation information stored in the reservation storage circuit (3).
If the discrimination signal (P) is not output from the audio/discrimination circuit (14) when the discrimination circuit (7) receives the timer output (T), the discrimination circuit (7) 15 minute extension part (3C) of memory circuit (3)
) is supplied with a control signal (C2). When the system controller (15) receives the control signal (C2), it supplies the Rew signal (Rcw) to the reel drive circuit (22), so the drive circuit (22) drives the reel stand (23) and drives the 5-recording tape. Performs rewinding operation. At this time, the PG double signal rotation detection circuit (
24), the number of rotations of the reel stand is counted by a counter (19), and this count value is given as one input of the coincidence comparison circuit (25). Since the tape count value at the start of recording is given from the memory circuit (21) as the other input of the coincidence comparison circuit (25), the coincidence comparison circuit (25) informs the system controller (15) when the two match. Outputs a match (R”f). When the system controller (15) receives a match signal, it outputs a reel drive circuit (22) of a Rew signal (Rev).
) to stop the drive of the reel stand.

This allows the recording tape (17) to be positioned at the same position (initial position) as at the start of recording.

On the other hand, when the 15-minute extension section (3C) receives the control signal (C2) from the discrimination circuit (7), it delays the recording start time initially stored in the start time setting section (3a) by 15 minutes. In this example, since the recording time is set, the broken line signal (C
3) It is not necessary to delay the recording end time, but in a % VTR that sets the recording end time, a recording end time setting section may be provided to extend the recording end time by 15 minutes.

In this way, after the recording start time is set to be extended for 15 minutes, the above-described operation is repeated again after 15 minutes have elapsed.

In a VTR with the above configuration, the scheduled broadcast time is, for example, 9:00.
For example, even if a foreign movie program that is broadcast for two hours from 0 to 9:00 starts broadcasting at 9:15 to extend the baseball broadcast that is being broadcast before it, the dual-language Japanese broadcast will not be detected as of 9:05. , the recording is stopped, the tape is rewound to the initial position, and the scheduled recording start time is set at 9:15, so that all the programs desired to be scheduled for recording can be reliably recorded. If the extension timer button (7) is turned off at the time of timer reservation, recording will start from the reserved recording start time (9:00) even though the baseball broadcast has been extended as in the past.

(G) Effects of the Invention As described above, according to the present invention, when the program for which timer reservation recording is desired is a dual-language broadcast such as a foreign film program, even if the broadcast time of the program before the reserved program is extended, detect,
Since the recording start time of the program desired to be recorded is automatically rafted by the extended time of the previous program, the scheduled recording program can be recorded reliably.
