BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of a spare switching system for a time difference transmitting apparatus according to the present invention. Although the same reference numerals in FIG. 1 denote the same parts as in FIG. 3, and a duplicate description will be omitted, FIG. 1 is a system diagram of the present example, and FIG. 2 is an operation explanatory diagram.

The difference between FIG. 1 and FIG. 4 is that the CPUs 2a and 2a of the working time difference sending device 1A and the spare time difference sending device 1B are different.
b is a modem 15a via an interface (not shown)
15b, and both modems 15a and 15b
The connections are made, for example, via an analog telephone line 16. Of course, it may be transmitted via a digital telephone line.

In the above configuration, the current time difference transmitting apparatus 1A may be located on the main broadcast station side, and the spare time difference transmitting apparatus may be located on the other broadcast station side. When a spare time difference transmission device is provided near the main broadcasting station, data may be exchanged by connecting the CPU 2a and the CPU 2b via a normal cable.

There is no need to provide the input keyboard 1b or the monitor display device 5b in the spare time difference transmission device 1B. Of course, the display device 1b may be provided in the spare time difference transmission device 1B, and data may be sent to the active time difference transmission device 1A only when a trouble occurs on the spare side to be displayed on the display device 1a.

Of course, according to the present configuration, the spare time difference transmitting apparatus 1B can be used as the current one, and the working time difference transmitting apparatus 1A can be used as the spare one.

The operation of the time difference transmitting apparatus having the above configuration will be described with reference to FIG.

First, the VTRs _1, 8a to VTR _n, 10a are input via the input keyboard 1a on the side of the current time difference transmitting apparatus 1A.
Control data for performing the above operation. For example,
As shown in FIG. 2A, it is assumed that a predetermined program that starts at 8:30 am and ends at 10:30 on the main broadcast station side and that the local broadcast station wants to start at 9:30 am and end at 11:30 am If there is a request, the operator inputs control data to the CPU 2a via the input keyboard 1a of the current time difference transmitting apparatus 1A. In this case, recording, rewinding, and reproduction are sequentially performed using, for example, three VTRs.

The result is the CP of the current time difference transmitting apparatus 1A.
The control data for recording and reproduction is supplied to U2a, and the control data for recording and reproduction is simultaneously supplied to the CPU 2b of the spare time difference transmitting apparatus 1B via the modem 15a → the telephone line 16 → the modem 15b. VTR1 to VTR3 of the time lag sending device 1B are also ready for operation.

That is, the working and standby time difference sending apparatuses 1A and 1B are in the parallel operation preparation state.

Here, 8:30 am based on the control data
Minutes, 8a or 8 of the working and spare first VTR 1
b becomes the first recording state REC shown in FIG. 2B. First
The video signal or the like is supplied to the 8a or 8b of the VTR 1 from the data input terminals 7a and 7b, and the recording command is sent to the CPU 2a.
And 2b.

Since the first VTRs 8a and 8b need to be in the reproduction state immediately before 9:30 am, in this example, the first rewind state REW is at least 1 hour before. the time obtained by subtracting the _first time is set to a first recording condition REC ₁ time.

Before the first VTR 1 8a or 8b completes the _first recording state REC1, the second VTR 2
As it is shown and C, enters the second recording condition REC _2. Therefore, the program currently being broadcast is the first and second VTRs 1 and VTR.
Recorded continuously in TR2. At 9:30 am while recording the current program on the second VTR 2, the first VTR 1
'S 8a or 8b enters the reproduction state PLAY _1, the reproduction output is output to the output terminal 13a or 13b through the multiplexer 12a or 12b, from local station via the output terminal 13a of the current time difference delivery device 1A A predetermined broadcast signal is aired.

The second VTR 2 also has a predetermined second recording state R
After EC _2, the first reproduction state PLA first VTR1
Second rewinding state PLAY _1, REW before the Y ₁ is terminated
_2, and the second VTR 2 is set to the second reproduction state PLAY ₂ at the same time as the end of the first reproduction state of the first VTR 1.

[0026] Now, the trouble in the second VTR2 second reproduction state PAAY spare time difference delivery device 1B trouble jet delivery device 1A working with ₂ times 14 are operated in parallel if the occurrence of the above Is supplied via the telephone line 16 so that the output of the on-air is immediately switched to the spare time lag sending device 1B unless an abnormality is displayed on the display device 5a. .

At this point, the second playback state PLAY ₂ is immediately turned on from the time 14 from the spare time lag sending device 1B and is turned on.

The spare third VTR 3 also enters the _third recording state REC ₃ just before the end of the _second recording state REC ₂ as shown in FIG. 2D, and enters the second recording state REC ₃ after the third rewinding state REW ₃ .
The third playback state PLAY ₃ is set at the same time as the end of the second playback state PLAY ₂ of the VTR ₂ , and the broadcast ends at 11:30 am

[0029] Note that the first VTR1 to third first reproduction state PLAY ₁ to third VTR3 in reproduction state PLAY
After the end of ₃ , the rewinding states REW _1a , REW _2a , and REW _{3a are established,} and the apparatus stands by for the next recording state. Since the present invention is operated as described above, it is not necessary to input data to the spare unit, not only can the operation man-hour be significantly reduced, but also it is necessary to monitor only the display device on the working side. I get it.

[0030]

According to the present invention, it is not necessary to input the same control data (this control data can be considered to change every day in the case of a broadcasting station) once to the two devices, the backup device and the working device. In addition to the above operation, it is only necessary to monitor only the monitor on the working side, so that a device capable of reducing fatigue can be obtained as compared with the conventional case of monitoring two screens.
