In particular, it is possible to change the preset playback and transmission time of the video signal.

B. Summary of the Invention The present invention provides a tape cassette automatic supply selection and playback device that automatically selects a plurality of tape cassettes on which different video signals are recorded based on a reproduction and transmission list, and reproduces and transmits the video signals. By making it possible to change the playback and transmission time of the video signal that has been reproduced during the playback and transmission operation, and by changing the display for each step of the change operation, the change operation can be performed accurately. The flexibility of the apparatus is increased by expanding the time in which the playback and transmission time can be changed.

C. Prior Art Conventionally, there is a tape cassette automatic supply selection and playback device (hereinafter referred to as a cart machine) shown in FIG.

In FIG. 3, the shelving device l has a plurality of shelves, for example, 40 shelves 1. ~14°, for example, arranged in parallel in the vertical direction, and each column 1.
A tape cassette 7 shown in FIG. 4, each recording a video signal, is housed at an angle of 14 degrees. As video tape recorders (VTRs) capable of playing back the tape cassette 7, for example, four VTRs 81 to 84 are installed on the shelf 1. ~1.
. They are arranged side by side in the same vertical direction as the direction in which they are arranged side by side.

A cassette transport device including an elevator 2 and a guide 3 for vertically guiding the elevator 2 is provided close to both the shelf device 1 and the VTR 8 (L to 84). A tape cassette 7 is sent and received between the two.

The elevator 2 is a first shelf provided for receiving tape cassettes 7 transferred from shelves 1+-1-0 of the shelf device 1 and transferring them to the VTR 8 or other shelves 11 to 14 of the shelf device. 5 and a second shelf 6 is provided for receiving tape cassettes 7 transferred from the VTR 8 and transferring them to the shelf device 1. Each column 5 and 6 is provided with a transfer actuator (not shown) for transferring the tape cassette 7 to the shelf device 1 and the VTR 8, and the actuator motor 9 or 10 is driven and controlled to transfer the tape cassette 7. The transfer to the shelf device 1 or VTR 8 is controlled. Further, the elevator 2 is moved up and down by an elevator drive device 4.

Therefore, the tape cassettes 7 stored in the predetermined shelves 11+ (X-1 to 40) are transferred to the predetermined VTRs 8, (y-1 to 4).
), the first
111. The elevator 2 is moved up and down to a position where the opening of the shelf 5 faces the opening of a predetermined shelf 18. Take out the tape cassette 7 from the.

After that, the opening of the first shelf 5 on the VTRa side opens to the VTR 8,
The elevator 2 is moved by the elevator drive device 4 to a position opposite to the cassette attachment/detachment opening, and then the actuator motor 9 is driven to move the tape cassette 7
Insert it into TR8 and load it.

Conversely, the tape cassette 7 loaded in a predetermined VTR 8v (V=1 to 4) is placed on a predetermined shelf 1. (v-1~40)
When the second shelf 6 of the elevator 2 is stored in the VT
R8, the tape cassette 7 is inserted, and then the elevator 2 is moved up and down until the second shelf 6 is in a position facing the predetermined shelf 1w, and after stopping at that position, the actuator The actuator is driven by the motor 10, and the tape cassette 7 is placed on the shelf 1. ．． will be stored in.

Such transfer of the tape cassette 7 is controlled by a control value ff14 of the microcomputer configuration. The control device 14 controls the transfer and playback of the tape cassette 7 based on the playback and sending list stored in the memory 15.

One tape cassette 7 records only the video signals for each broadcast, such as a so-called commercial video signal or a video signal of a news incident. As shown, a bar code 11 representing various data related to the recorded contents of the tape, such as the storage shelf number, reproduction transmission start time, reproduction transmission time, title of the recorded contents, etc., is attached to the tape. On the shelf 5 of the elevator 2, there is an optical sensor 12 that detects this barcode 11.
is provided, and a detection signal from the optical sensor 12 is provided to the control device 14.

When the power of the cart machine is turned on, the control device 14 takes out the tape cassettes 7 sequentially from all the shelves 1 to 14 degrees to the shelf 5, reads the barcode 11 via the optical sensor 12, and then removes the tape cassettes 7 from the shelves 1 to 14 degrees. 7 to the original shelf 1.
14 degrees, create a reproduction transmission list 20 as shown in FIG. 5 based on the read data, and store it in the memory 15.
be stored in Further, for example, it is possible to separately input a reproduction transmission list 20 through the input device 13 having a key matrix configuration, and the reproduction transmission list 20 input in this way is also stored in the memory 15.

Note that this reproduction/sending list 20 is displayed on a display device 16 having a CRT configuration, for example, and is displayed on the shelf 1. Display element LL-1 corresponding to ~14°
7,. is lit to allow the operator to visually confirm the current status, such as the delivery stage.

Here, the items on the reproduction and transmission list 20 include the unit (
A transmission number NO with a different code (hereinafter referred to as an event), a title TTL related to the event of the tape cassette 7, a playback transmission start time at which the tape cassette 7 is played back and transmission begins as an output signal of the cart machine (the (time at which the broadcasting starts by the broadcasting device) STT, reproduction transmission time (broadcasting time) for outputting the reproduction signal from the tape cassette 7; cumulative time for transmitting the DLJR1 output signal; ACT; fence II for storing the tape cassette 7. 14° number BN, VTR8 loading tape cassette 7
There are numbers VT from 1 to 84, etc. Note that the sending number NO has nothing to do with the sending order, and rBK at the sending number NO
In J, there is a blank period during which the cart machine stops reproducing and transmitting operations in order to broadcast the television signal from the television camera device.

The control device 14 selects the tape cassettes 7 from the shelves II to 14 according to the playback order based on the playback/sending list 20.
At that time, the tape cassette 7 is checked based on the read barcode 11 and loaded into the VTR 8r to 84. When the playback start time comes, the event is played back, and when the playback is finished, the tape cassette 7 is loaded into the VTR 8r-84. T
Discharge from R8I~84 and return to the original shelf lI~14°,
At the same time, the item is deleted from the reproduction/transmission list 20 on the display device 16.

Here, so that the VTRs 8+ to 84 are always loaded with 3 to 4 tape cassettes 7 to be played from now on, when the tape cassette 7 that has finished playing is ejected, a new tape is created according to the playback and sending order of the event. The cassette 7 is loaded immediately, and each VTR8r to 84
is always controlled to be in a playback or playback standby state.

In this way, under the control of the control device 14 based on the reproduction/transmission list 20, an event from any of the VTRs 8-84 is output as an output video signal, and this is sent to the next stage, for example, by a switcher, to another cart machine. The output video signal is alternately switched with the output video signal from the TV camera device or the direct video signal from the television camera device, or the video signal is added with a special effect, and then given to the broadcasting device and broadcast.

Thus, events from tape cassette 7 are broadcast in a predetermined order and for a predetermined period of time.

D Problems that the invention aims to solve By the way, some television programs, such as sports programs, do not have fixed start times, interruption times, and end times. It may be necessary to change the content listed in the playback/transmission list.

Therefore, conventionally, each item related to each event can be changed before the reproduction and transmission operation of the event is started.

However, in practice, there are cases where it is necessary to change the playback and transmission time even after the playback and transmission operation of an event has started.For example, in the case of a news program, a so-called live broadcast video signal, in which an announcer is captured, is sent from a television camera device. And vT.

It is created by switching and transmitting the recorded news video signal (event) played back from the tape cassette 7 via R1, and the event is played back and transmitted in order to adjust the time for transmitting the live broadcast video signal. There may be times when it is desired to change the playback/sending time of the event during the operation.

As mentioned above, the conventional device does not allow changes in playback and sendout time due to such events during playback, and therefore lacks flexibility and is still inadequate as a tape cassette automatic supply selection playback device. I didn't get it.

The present invention has been made in consideration of the above points, and is an automatic tape cassette supply selection that can change the set playback and sendout time of an event during playback and sendout, and allows the changing operation to be performed accurately. The aim is to provide a playback device.

E Means for solving problem
The control device 14 sequentially takes out predetermined tape cassettes 7 based on the playback/transmission list stored in 5 and transfers them to a plurality of video tape recorders 81 to 84 via the cassette transport device (2, 3). The tape cassette 7 is loaded into the tape cassette 7, and the video signal is transmitted from the reproduction transmission start time STT of the reproduction transmission list 20 for a preset reproduction transmission time DUR of the reproduction transmission list 20, and after the transmission is finished, the tape cassette 7 is returned to the original shelf 1. ~
In the tape cassette automatic supply selection reproducing apparatus which returns the tape cassette to 14 degrees and repeats such operations sequentially and displays the elapsed playback and sendout time on the display device 16, the control device 14 inputs the playback and sendout time again from the input device 13 during the playback and sendout operation. Playback transmission time DUR set in advance when setting mode is instructed
is displayed, and when a new playback and sendout time is input via the input device 13, the new playback and sendout time is reset and displayed, and an instruction to end the reset mode is given via the input device 13. The elapsed playback time is now displayed when the playback is played.

The F-effect control device 14 is configured to allow a change in the preset reproduction and transmission time DUR during the reproduction and transmission operation of the video signal. As a result, the time available for changing the playback/transmission time DUR has been expanded, making it easier to change the broadcast content.

Furthermore, since the display is changed for each step of the reproduction/transmission time DUR change operation, the operator can visually check the input operation and perform the input operation accurately.

Embodiment G An embodiment of the present invention will be described in detail below with reference to the drawings. In this embodiment, the control device 1
4 is loaded into a predetermined VTR 8.
, and when the reproduced event is broadcast, the control device 14 updates and displays the reproduction transmission time DUR item 30 in the reproduction transmission list 20 on the display device 16 according to the elapsed time. The memory 15 is provided with a memory area for storing a preset reproduction transmission time (set reproduction transmission time) and a memory area for storing the elapsed time since the start of broadcasting of the event. The remaining time for playback and transmission obtained by subtracting the elapsed time from the set playback and transmission time is expressed as the playback and transmission time D.
Displayed in item 30 of this event in the UR.

For example, when an event with a set playback and sendout time of 40 seconds becomes the order of playback and sendout based on the playback and sendout list 20, the control device 14 causes the tape at the running start point (cue up point) to run and playback. At this time, the item 30 of this event in the playback transmission time DUR on the display device 16 is ro.
o:40J(7) Displays 40 seconds. Eventually, when the tape exceeds the broadcast start point (start of message point), the control device 14 divides the control signal CTL picked up from the tape to form a clock signal with a period of 1 second, and based on this clock signal, Set item 30 of playback transmission time DUR according to the elapsed time of playback transmission.
oo:40"→r00:39"→roo:38J...
Display a countdown like this.

As the playback transmission operation progresses and reaches the broadcast end point (end of message point), the display in item 30 of the playback transmission time DUR that has been counting down becomes "OO:00", indicating that the tape is still running beyond the broadcast end point. , the control device 14 changes the item 30 of playback transmission time DUR from roo:OOJ to " according to the elapsed time beyond the end of message point
00:01J-r0012J... is counted up and displayed, and when the tape finishes running at the running end point (one point over the end of message), the counting operation is stopped at that count value and displayed.

In addition to the above configuration, this embodiment has a configuration for changing the set reproduction and transmission time during the reproduction and transmission operation of an event.

As shown in FIG. 2, the input device 13 includes an rREV I SEJ key 21 as a change command key, an rENTERJ key 22 as an input operation end key, and a numeric keypad 23.
When the control device 14 senses a key input from the ``rREV I SE'' key 21 during reproduction and transmission of an event, it assumes that the reset mode has been instructed and reproduces and transmits the settings shown in FIG. Run the time change program.

That is, the control device 14 uses the rREV I SEJ key 2.
Step SP by sensing the key human power from 1
After starting the program at step I, the program moves to the next step SP2, where the cursor is set to the item 30 of the playback transmission time DUR for the event being played back and sent out on the display device 16, and at the same time, the flow moves to step SP3, where the playback starts. The transmission time DUR item 30 is returned to the initial set playback transmission time stored in the memory 15 and displayed.

For example, an event with a set playback and transmission time of 40 seconds is set to 1.
If the rREV I SEJ key 21 is pressed during the 5-second period, a countdown will occur immediately before the ro button is pressed.
The display that was "o: 25" is changed to "roo: 4°" by executing step SP3.

After completing step SP3, the control device 14 moves to the next step SP4, takes in the data of the newly set playback and send-out time DUR input by the operator via the numeric keypad 23 of the input device 13, and takes in the data of the newly set playback and send-out time DUR. For example, if the newly set playback and sendout time is 1 minute, display it in the playback and sendout time DUR item 30 of the display device 16 by executing step SP4. is roll:00
" is displayed.

Upon completion of step SP4, the control bag wt14 moves to the next step SP5 and determines whether or not the input set playback and transmission time is normal. Here, the new set reproduction transmission time may extend or shorten the initial setting reproduction transmission time. However, it cannot be shorter than the reproduction transmission time that has already passed, and, for example, the new If the set playback and transmission time is shorter than the playback and transmission time that has already passed, a negative result is obtained in step SP5, the process proceeds to step SP6, an error is displayed, and the process returns to step SP4. Therefore, the operator will recognize that he has made an erroneous operation by looking at the error display, and will have to input a new set playback and transmission time.

On the other hand, if a positive result is obtained in step SP5, the control device 14 proceeds to step SP7, and the input device 1
When there is key power from the rENTERJ key 22 of 3, it is determined that a command to end the reset mode has been given, and the elapsed time from the start of event transmission is subtracted from the new setting playback transmission time, and at the time of key power. The remaining reproduction transmission time to be displayed is determined, and the process moves to the next step SP8, where the remaining reproduction transmission time is displayed as the reproduction transmission time D of the display device 16.
0 to be displayed in item 30 of UR For example, if the newly set playback and sendout time is 1 minute, and the time when the "rENTER" key 22 is pressed is the time when only 19 seconds have elapsed from the start of message point, the playback and sendout time DUR is displayed. Item 30 displays roo:41J.

When this display ends, the control device 14 performs step SP9.
Then, the program returns to the main program that counts according to the elapsed time, and the program for changing the set playback and transmission time is terminated.

In the above configuration, if the initially set playback and transmission time (for example, 40 seconds) is not changed during the event playback and transmission operation, the control device 14 displays the display device 16 from the time when the tape passes the start of message point. Item 30 of playback transmission time DUR is set to r according to the elapsed time of playback and transmission.
oo:40J→r00:39”→roo:38J...
When the tape reaches the end of message point, rQQ:QOJ is displayed, and the count continues until the end of the tape run.

On the other hand, when there is a change in the initial setting reproduction and transmission time during the event reproduction and transmission operation, the following operation occurs. Suppose that the initial setting playback and sending time is 40 seconds, the new setting playback and sending time is 1 minute, and when 15 seconds have passed from the start of message point, rR
When the EV I SEJ key 21 is pressed and 19 seconds have elapsed from the start of message point, rENTER is pressed.
Suppose that the J key 22 is pressed.

In this case, the control device 14 changes the playback sending time DUR item 30 on the display device 16 from the time when the tape passes the start of message point according to the elapsed playback sending time.
o:40J→rob:39"→roo:38J, and so on. Eventually, 15 seconds passed,
When the display becomes "roo:25", rREV I
When SEJ key 21 is pressed, control? The II+ device 14 sets the cursor to the reproduction transmission time DUR item 30 in step SP2, and changes the display to roo:40J representing the initial reproduction transmission time in step SP3.

After that, in step SP4, display r01+oOJ representing the newly set playback transmission time that has been correctly input, have the operator confirm this set time, and press the [ENTERJ key 22].
At the time when is pressed, step "SF3 sets the remaining broadcast time, which is the new set playback transmission time (1 minute), minus the time that has already passed (L9 seconds), which is roo:41.
” is set and displayed, and a countdown is made as the time passes.

Therefore, according to the embodiment described above, the operator can easily recognize the elapsed event transmission time, and can easily change the set playback transmission time during the event transmission operation by a simple operation. Therefore, at each stage during the conversion operation, the initial setting playback and sending time, the new setting playback and sending time, etc. are displayed on the display device 16, so that the operator can make desired changes while looking at the display. It can be done accurately.

Incidentally, instead of displaying the set reproduction and transmission time etc. on the display bag 216, it may be possible to display it on a separate display tube, but if this is done, the operator can easily see the relationship with information regarding reproduction and transmission of other events. cannot be easily grasped, and it cannot be said that the display is sufficient.

H Effects of the Invention As described above, according to the present invention, it is possible to change the set reproduction and transmission time by a simple operation during the reproduction and transmission operation of an event, and it is possible to perform the operation accurately by visually confirming the operation. A tape cassette automatic supply selection playback device can be easily obtained.
