Regarding
In particular, the present invention can be applied to automatic television signal transmission devices in television broadcasting stations.

B. Summary of the Invention The present invention provides a tape cassette automatic supply selection and playback device that sequentially reproduces and transmits video signals recorded on a plurality of tape cassettes based on a reproduction transmission list, in which the reproduction transmission list is divided into a plurality of parts and recorded on a recording medium. In addition to recording as different files, the operator can give load commands to multiple files, and the file to which the load command has been given can be automatically loaded, thereby preventing equipment trouble. This minimizes damage to the playback and transmission list and simplifies manual operations for loading.

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. 5, the shelving device l includes a plurality of shelves l, for example 40 shelves l, arranged vertically at an angle of ~14°, and each column 11
.about.14 degrees are housed with tape cassettes 7 shown in FIG. 6 each recording different video signals. As a video tape recorder (VTR) capable of reproducing the tape cassette 7, for example, four VTRs 8, .

A cassette transport device consisting of an elevator 2 and a guide 3 for vertically guiding the elevator 2 is provided in close proximity to both the shelf device 1 and the VTR 8 (8, to 84). The tape cassette 7 is sent and received between the VTRs 8.

The elevator 2 receives the tape cassettes 7 transferred from the shelves It to 14 of the shelving device 1 and moves them to a first shelf 5 provided to receive the tape cassettes 7 transferred from the shelves It to 14 of the shelving device 1 and transfer them to the VTR 8 or other shelves 11”14 of the shelving device. , and a second shelf 6 for receiving tape cassettes 7 transferred from the VTR 8 and transferring them to the shelf device 1.In each column 5 and 6, the tape cassette 7 is placed between the shelf devices 1 and 1. A transfer actuator (not shown) for transferring the tape cassette 7 to the VTR 8 is provided, and the actuator motor 9 or 10 is driven and controlled to transfer the tape cassette 7 to the shelf device 1 or the VTR 8. Further, the elevator 2 is moved up and down by an elevator drive device 4.

Therefore, the predetermined shelf 1. The tape cassette 7 stored in (x=1 to 40) is transferred to the specified VTR 8, (y-t to 4)
When loading the tape cassette 7 into a tape cassette, the elevator drive device 4 moves the elevator 2 up and down to a position where the opening of the first shelf 5 faces the opening of the predetermined shelf 1x°, and the tape cassette 7 is taken out from the shelf 18.

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

Conversely, the tape cassette 7 loaded in a predetermined VTR 8v (V-1 to V-4) is placed on a predetermined shelf 1. (w-1~4
0), the elevator 2 moves to a position where the second shelf 6 faces the VTR 8, the tape cassette 7 is inserted, and then the second shelf 6 is moved to a predetermined shelf 1. ．． The elevator 2 is moved up and down until it is at a position facing
will be stored in.

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

Each tape cassette 7 records a video signal for each broadcast, such as a so-called commercial video signal or a video signal of a news incident. Each tape cassette 7 is played back once and sent out. As a unit (hereinafter referred to as an event), a reproduction/transmission list 20 shown in FIG. 7 is formed according to the transmission order of the events. The reproduction sending list 20 is formed in advance and stored in an external recording medium such as a floppy disk, and is transferred to the buffer memory 15 from an external memory device 18 such as a floppy disk drive when the input device 13 is operated. being done.

Here, the items in the reproduction and transmission list 20 include a transmission number NO, which has a different serial number assigned to each event, a title TTL regarding the event of the tape cassette 7, and a start of reproduction of the tape cassette 7 and transmission as an output signal of the cart machine. Playback transmission start time (time when broadcasting starts by the next stage broadcasting device) STT, playback transmission time (broadcast time") DUR at which the playback signal from the tape cassette 7 is output
There are the cumulative time ACT for sending out one output signal, the number BN of the shelves II to 14 degrees that store the tape cassette 7, the number VT of the VTRs 8+ to 84 in which the tape cassette 7 is loaded, etc. Note that the sending number No. has nothing to do with the sending order.
Further, "BK" in the transmission number No. broadcasts a video signal from a television camera device or another cart machine, and therefore indicates a blank period during which the cart machine stops reproducing and sending out operations.

Based on this playback/sending list (20), the control device 14 selects tape cassettes 7 from the shelf il~14° according to the playback order.
is taken out to the shelf 5 of the elevator 2, and at that time, the tape cassette 7 is taken out based on the bar code 11 attached to the back of the tape cassette 7 and representing various data related to the tape recorded contents by the optical sensor 12 provided on the shelf 5. After confirming that it is the specified tape cassette 7, load it into the VTR8+~84, play it when the playback start time comes, and when the playback is finished, eject the tape cassette 7 from the VTR8+~84 and return it to the original shelf 1. ．． -14 degrees, and at the same time delete that item from the reproduction transmission list stored in the buffer memory 15 and the reproduction transmission list 20 displayed on the display device 16.

In addition, in order to allow the operator to visually check the reproduction and transmission stage, a reproduction and transmission list 20 is displayed on the display device 16, and
The display elements 171-174° corresponding to the shelves 11-14° from which the tape cassette 7 is taken out are turned on.

VTR8+~84 always has 3 files to be played from now on.
~4 tape cassettes 7 are loaded. When a tape cassette 7 that has finished playing is ejected, a new tape cassette 7 is immediately loaded in accordance with the playback and sending order of the event, and each V T R8+~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 and transmission list 20, an event from any of the VTRs 81 to 84 is output as an output video signal, and this is transmitted to another cart by a switcher in the next stage, for example. It is alternately switched with the output video signal from the machine or the direct video signal from the television camera device, or added with special effects, 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.

Problems that invention D aims to solve By the way, is there actually a system? Il outfit? ! ! Reference numeral 14 is commonly used by a plurality of cart machines, and is designed to control the reproduction and transmission of all events to be transmitted in one day.

For example, the number of events related to commercial video signals is approximately 500 to 600 per day, and the number of events related to news video signals is approximately 200 per day.

In this way, the reproduction and transmission list 20 including a large number of events is transferred from the external storage device 18 to the buffer memory 1 of the control device 14.
If the data is loaded and displayed on the display device 16 by an operation once every five, subsequent operations for loading become unnecessary.

However, if the load unit (hereinafter referred to as a file) is made larger in this way, the scope of damage such as data corruption will increase if a file cannot be loaded due to device trouble. In addition, even when changing the contents of a file, if the file contains a large number of events, it takes a lot of time to search for the event to be changed, which requires a lot of effort.

Therefore, we divided the event into multiple playback and transmission lists 20.
It is conceivable to create a file and load the divided playback/transmission list 20 as a file.

However, with this method, once all events in one file have been played back and transmitted, input operations are required to load the next file, and the operator has to perform the operations each time, resulting in a lack of workability. becomes. Additionally, there is a risk of forgetting to load the program, and there is also a risk of broadcasting being interrupted.

The present invention has been made in consideration of the above-mentioned conflicting problems, and provides a tape cassette automatic supply selection and playback device that can improve safety against troubles in loading operations and ensure continuous transmission of events. This is what I am trying to do.

Means for Solving Point El￥31H In order to solve this problem, in the present invention, the control device 14 has a plurality of stages based on the playback and transmission list 20 that records matters related to events for each broadcast in accordance with the broadcast order. Shelf 1. A shelf device that stores tape cassettes 7 each recording different video signals at ~14 degrees! A predetermined tape cassette 7 is taken out from the cassette carrying bag y1 (
2, 3) via multiple videotape recorders 8. ~8
The tape cassette 7 is loaded into a predetermined tape cassette 7, and the video signal is reproduced and transmitted for a preset reproduction transmission time DUR from the reproduction transmission start time STT of the reproduction transmission list 20, and after finishing, the tape cassette 7 is returned to the original shelf 11 to 14. In the tape cassette automatic supply selection and playback device which erases the items related to the above events and repeats the above operation sequentially, the playback and sending list is divided into sending time slots based on the sending start time STT of each event. , record to the recording medium as a playback list file, and control bag! ff114
loads the reproduction transmission list file into the built-in buffer memory 15 based on the load command from the input bag ff13, and also loads the free memory capacity of the buffer memory 15 when the load command is given for multiple reproduction transmission list files. , and the capacity of the playback/transmission list file that has not been loaded and should be loaded next, and if the free memory capacity is larger, it is loaded into the buffer memory 15.

The F effect playback transmission list 20 is set to the transmission start time STT of each event.
Based on this, the data is divided into segments according to the transmission time period and recorded on the recording medium as different files.

As a result, each file is the unit that suffers damage such as destruction due to device trouble, and the range of damage can be reduced.

However, if you do this, each file will be stored in the control bag W14.
The input operation for loading into the buffer memory 15 becomes complicated.

Therefore, in addition to allowing the operator to specify (declare) multiple files to be loaded with a single input operation, when the free memory capacity of the buffer memory 15 reaches the capacity to load the next file, automatic Loads the next unloaded file specified.

G example Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

In the case of this embodiment, the reproduction transmission list 20 is divided by transmission time zone based on the reproduction transmission start time STT, and the divided reproduction transmission list 20 is recorded as files having different file names on a floppy disk as a recording medium. I try to store it in advance. For example, 6 a.m.
Store the playback and sendout list of events that have a playback and sendout start time STT between 7:00 and 7:00 a.m. in the file with the file name rAAAJ, and store the playback and sendout list of events that have a playback and sendout start time STT between 7:00 and 8:00am as a file. Store the playback and transmission list of events whose playback and transmission start time STT is between 11:00 p.m. and 12:00 p.m. in a file with the file name rRRRJ.
I am trying to store it in a file.

In addition, in this embodiment, the input device 13 is configured to specify (declare) load instructions for multiple files with a single input operation, and the input device 13 uses a floppy disk as one of the function keys for the display device 16. rLOAD for loading a file from the external memory device 18, which is an attached floppy disk drive, into the buffer memory 15 and giving an input command for causing the display device 16 to display a playback transmission list for the file;
Equipped with FILEJ key. Also, this rL.

When the AD FILEJ key is pressed, the display device f
A secondary function key for f116 appears, and one of the secondary function keys is a "LINK" key that gives a command to combine different files. In addition, the input device 13
is provided with an rENTERj key which indicates the end of an input operation for selecting one operation mode and which gives an execution command.

If the operator wants to sequentially load multiple files (for example, files rAAAJ, rBBBJ, "CC'CJ") with one input operation, use rLOAD F.
ILEJ key → rL After pressing the INKJ key, enter the file names in sequence, then press the ENTERJ key.Also, if you want to load one file with one input operation, use rLOAD. FI
After pressing the LEJ key, enter the file name and press &rE.
Just enter the NTERJ key.

In this manner, when the operator presses the "rENTER" key, the control device 14 executes the program in the specified operation mode of the file to be loaded shown in FIG.
Start with P1. Then, the process moves to the next step SP2, and it is determined whether there is an input command for a file to be loaded.

If a negative result is obtained in this step SP2, the program moves to step SP3, ends the program, and moves on to another program. On the other hand, if a positive result is obtained in step SP2, the control device 14 performs the next step S.
Proceeding to P4, it is determined whether the input file name is correct.

For example, if a negative result is obtained in step SP4 due to input of a file name that includes characters that are prohibited to be used in the file name, the process moves to step SP5 and an error message is displayed on the display device 16. If a positive result is obtained in step SP4 due to correct input, the process proceeds to the next step SP6, where it is determined whether the file join command input this time is the same as the previous input command, and if a positive result is obtained. , since there is no need to change the contents, the program moves to step SP3 and ends the program.

On the other hand, if a positive result is obtained in step SP6, the control device 14 moves to the next step SP7, determines whether the file name input for the first time this time is a file at the file base, and obtains a negative result. The program then moves to the above-mentioned step SP5, displays an error on the display device 16, and then ends the program. On the other hand, if a positive result is obtained in step SP7, the process moves to step SP8, and it is determined whether or not there is a file that has already been loaded and for which no input command has been given this time, in other words, there is a file that should be canceled.

If a positive result is obtained in this step SP8, the control device 14 moves to step SP9, erases the file to be canceled from the buffer memory 15, moves to step 5PIO, sets a new file designation to be loaded, and sets that file. The name is displayed, for example, in the upper left corner of the display surface DES on the display device 16, as shown in FIGS. , display the file name and exit the program.

Here, steps SP6 and S in this program
In the judgment step F3, a unique judgment result is always obtained in the first input operation. That is, step SP
In step SP8, a positive result is obtained, and in step SP8, a negative result is obtained.

For example, the correct file rA for the first input operation.
When AAJ, rBBBJ, and rcccJ are entered manually in this order, rAAA appears in the upper left corner of the display surface DES of the display device 16, as shown in FIG. 3(A).

BBB and CCCJ are displayed, and rAAAJ, rBBBJ, and rcccJ are specified as files to be loaded.

Also, for example, the file [AAAJ,
rBBBJ, rCCCJ are input, and file rA is already
At the stage when AAJ, rBBBJ are loaded into the buffer memory 15, the correct files rAAAj, rc
When ccJ, rD D DJ is input, step SP
8, a positive result is obtained, the file rBBB" is erased from the buffer memory 15 in step SP9, and rAAA, CCC5D are displayed in the upper left corner of the display surface DES of the display device 16 in step 5P10, as shown in FIG. 3(B).
DDJ is displayed and rAA is the file to be loaded.
AJ, rcccJ, and rDDDJ are specified.

Furthermore, in this embodiment, the buffer memory IJ15
The capacity is set to be such that it can store, for example, 315 events (playback/transmission list) 20, and the maximum number of events that each file can have is limited to 300. This is because, for example, if a large number of events can be stored, the device will be greatly affected by the occurrence of trouble, which will reduce safety.

However, in this case, even if multiple files are specified in one input operation, all the specified files cannot be loaded into the buffer memory 15, and only some of the specified files are loaded. Ru.

Therefore, in order to distinguish and display loaded files and unloaded files, the control device 14 sets and displays the newly inputted file in step 5PIO as shown in FIG. 3 (A). ), the files rAAAJ and "BBBJ" are displayed in reverse (white) REV as shown for "file rAAA" in FIG. 3(B).

The automatic loading operation for loading a file that has been specified to be automatically loaded but has not yet been loaded is executed according to the processing procedure shown in FIG.

That is, after starting the program in step 5P20, the process moves to the next step 5P21, where the control device 14 determines whether there is a file specified to be loaded. For example, if all of the specified files have already been loaded, a negative result will be obtained.

If a negative result is obtained in this step 5P21, the process moves to step 5P22 and the program is ended, whereas if a positive result is obtained, the process proceeds to the next step 5P23.

This step 5P23 is a step for determining whether or not there is free memory capacity in the buffer memory 15 to load the next file. A size comparison is made.

As a result, if a negative result is obtained because there is no free memory capacity to load, the program proceeds to step 5P22 described above and the program is terminated, and if a positive result is obtained because there is free memory capacity, the process proceeds to the next step 5P24. The next file is loaded into the buffer memory 15, and the program then proceeds to step 5P25 to invert the corresponding file in the upper left corner of the display surface DBS of the display device 16, and then terminates the program in step 5P22.

For example, the files to be loaded are a file rXXXJ with 50 events and a file rY with 40 events.
When YYj and a file rZZZJ with 100 events are input, by executing the processing procedure shown in FIG. 2, all files rXXXJ, rYYYJ, rZZZJ are is immediately loaded into the buffer memory 15, and all file names are displayed in reverse video on the display device 16.

Also, the files to be loaded are the file rPPPJ with 300 events and the file r with 250 events.
When QQQj and the file rRRRJ with the number of events 300 are inputted, at this point in time, the result is shown in Figure 4 (B1).
As shown in , there is only file capacity for the file "PPPJ", so only the file "rPPPJ" is loaded into the buffer memory 15, and only the file name "rPPPJ" is displayed in white in the file name display in the upper left corner of the display screen DBS of the display device 16. Ru.

The reproduction and transmission operation of each event progresses, and the event that has completed the reproduction and transmission operation is erased from the buffer memory. Eventually, the file rQQQj is loaded into the memory area of the number of events memory capacity of the empty memory capacity, and at this time, the file name In the display files rPPPJ and rQQQ
J is displayed in white.

In the same way, the playback and transmission operation progresses, and the file “QQQJ
When only 15 events remain and the free memory capacity is equivalent to 300 events, the file rRRRJ is loaded and all file names are displayed in white, as shown in FIG. 4 (B3).

According to the embodiment described above, the capacity of the buffer memory 15 is selected to be small, and the number of events for each file is set to 3 at maximum.
Since the event is limited to 00 events, it is possible to limit the adverse effects such as data destruction due to equipment trouble to a small range, thereby increasing safety. Additionally, multiple files can be specified to be loaded with a single input operation, and the specified files are automatically loaded, reducing the burden on the operator and improving operability. .

In addition, in the above, when specifying multiple files with one input operation, use the rLOAD FILE key, rL
After pressing the INKJ key, the file name is entered consecutively, but rLOAD F I
It is also possible to input file names consecutively immediately after pressing the LEJ key.

Also, if you want to perform a new input operation to cancel a file that has already been loaded, click "LOAD F
After pressing the ILEJ key, enter the file name, and if you want to perform a new input operation to change a file that has not been loaded yet, press the "LOAD FILEJ key, r
The input operations may be distinguished by inputting the file name after pressing the LI'NKJ key. Even in this case, the same effect as described above can be obtained.

H Effects of the Invention As described above, according to the present invention, the reproduction transmission list recorded on a recording medium is divided into a plurality of files and stored, and the operation of loading the files from the recording medium into the buffer memory of the control device is automatically performed. Therefore, it is possible to easily obtain a tape cassette automatic supply selection and playback device that has improved safety against device trouble and improved operability.
