Abstract

PURPOSE:To improve the preparation of a reproducing and sending list and the operability of inputting operation by automatically inserting an empty event on a reproducing and sending list. CONSTITUTION:At the time of an insertion command is issued, an empty event is inserted automatically before an event to which starting time of reproducing and sending is inputted. Then, an operator can prepare a reproducing and sending list 20 without making inputting operation beforehand on the empty event by giving an insertion command. Time of reproducing and sending DU of the empty event is determined from time information of preceding and succeeding events, and the reproducing and sending list 20 that had contradiction in time at the time of inputting can introduce no contradiction by executing operation of insertion. The empty event thus inputted is different from one for which the operator inputted time information directly, and accordingly, there are cases where the time differs from desired time. Therefore, in some cases the lapse of time of the empty event exceeds reproducing and sending time on the list 20. Accordingly, different display is made between the cases where an elapsed time exceeds and does not exceed a time on the list.

B. Summary of the Invention The present invention provides a video signal recording medium supply selection and playback device that takes out a video signal recording medium for each event based on a reproduction transmission list and sequentially reproduces the recorded video signals, in which the reproduction transmission time is stopped. When a command to insert a blank event is given, the blank event is inserted immediately before the event for which the playback start time is input, and when the blank event is executed, the elapsed time is set to the time on the playback sendout list. By notifying whether or not the blank event has been exceeded, it is possible to simplify the input and creation operations of the playback and sendout list, to make the playback and sendout list consistent in time, and to ensure continuity before and after the blank event. This is what I did.

C. Prior Art Conventionally, there is a video signal recording medium supply selection and playback apparatus (hereinafter referred to as a cart machine) using a tape cassette as a video signal recording medium, as shown in FIG.

In FIG. 5, the shelf device 1 includes, for example, 40 shelves 11 to 40.
The tape cassettes 2 shown in FIG. 6, each having a different video signal recorded therein, are housed in each column II to 14 degrees. As a video tape recorder (VTR) capable of reproducing the tape cassette 2, for example, four VTRs 3+ to 34 are arranged side by side in the same vertical direction as the direction in which the shelves 11-14 degrees are arranged side by side.

A cassette transport device consisting of an elevator 4 and a guide 5 for vertically guiding the elevator 4 is provided adjacent to both the shelf device 1 and the VTR 3 (3t to 34). The tape cassette 2 is sent and received between the VTRs 3.

The tape cassette 2 is placed in the elevator 4 with the shelf device 1 and the VT.
Transfer actuator motor for transferring to R3 (
(not shown) is provided, which drives and controls the actuator motor 6 to move the tape cassette 2 to the shelf device 1 or the VT.
The transfer is controlled to R3. Further, the elevator 4 is moved up and down by an elevator drive device 7.

Transfer and playback of the tape cassette 2 is controlled by a control device 8 comprised of a microcomputer.

The control device 8 controls the transfer and playback of the tape cassette 2 based on a playback and sending list stored in a built-in buffer memory 9.

Each tape cassette 2 records a video signal for each broadcast, such as a so-called commercial video signal, and each tape cassette 2 is played once and sent out as a unit (hereinafter referred to as an event). A reproduction transmission list is formed according to the transmission order of events. The reproduction transmission list is formed in advance and stored in an external recording medium, and is transferred from the external memory device 11 to the buffer memory 9 when the input device 10 is operated, or is input directly from the input device 10 and stored on the buffer memory 9. be done.

Based on this reproduction sending list, the control device f8 takes out the tape cassettes 2 from the shelves 11 to 14 degrees to the elevator 4 according to the order of reproduction, and at that time, reads the barcode 13 (FIG. 6) read by the optical sensor 12. Based on this, it is confirmed that a predetermined tape cassette 2 has been taken out, and the tape is loaded into the VTR 3, and then the tape is positioned at the reproduction/sending start position.

There are some cart machines in which the control device 8 automatically issues a reproduction command based on a playback transmission list, and there are also cart machines in which the reproduction command is issued by the operator's operation of the input device WIO. Thomasin starts regeneration when a regeneration command is given. When the playback is finished, the control device 8 transfers the tape cassette 2 to the VTR 3.
At the same time, the playback list stored in the buffer memory 9 and the playback sendout list are displayed on the display device 14 to allow the operator to visually check the playback and sendout stages. Remove the item from the list.

VTR3+ to 34, the 3 that should always be played from now on
When the tape cassette 2 that has finished playing is ejected, a new tape cassette 2 according to the playback and sending order of the event is immediately loaded so that ~4 tape cassettes 2 are loaded, and each VTR3+ .about.34 are always controlled to be in a reproduction or reproduction standby state.

In this way, under control based on the playout list,
An output video signal is output from any of the VTRs 31 to 34, and this is selectively switched to an output video signal from another cart machine or a direct video signal from a television camera device by a switcher in the next stage, or Special effects are added to the broadcast equipment and broadcast.

D Problems to be solved by the invention By the way, commercial video signals are generally 15 seconds long.
Since the broadcast unit is 30 (seconds), the number of events related to commercial video signals is several hundred events per day.Therefore, the playback and transmission list of the cart machine that plays and transmits commercial video signals is extremely large. For example, even if the playback and transmission list is divided into morning and afternoon lists, it will still be large.

Therefore, it takes a lot of effort and time to create and input the playback and transmission list.

Furthermore, since there are a large number of events to be input, input errors are likely to occur, and there is a risk that a playback and transmission list that is inconsistent in time may be formed. If such a contradictory reproduction/transmission list is loaded into the buffer memory 9 and reproduction/transmission is controlled, problems such as interruption of broadcasting may occur.

The present invention has been made in consideration of the above points, and it is an object of the present invention to provide a video signal recording medium supply selection and playback device that can facilitate the creation and input operations of playback and transmission lists, and can also modify inconsistent playback and transmission lists. That is.

E Means for Solving the Problem In order to solve this problem, in the present invention, a shelf having a plurality of shelves is provided based on a reproduction transmission list 20 in which items related to events for each broadcast are listed in accordance with the broadcast order. A predetermined video and recording medium 2 are taken out from the device 1 and transferred to the video signal reproducing device 3 via the conveying device (4, 5).
In the video signal recording medium supply selection and reproduction device, which is controlled by the control device 8, the video signal recording medium supply selection and reproduction is carried out in such a manner that the video signal recording medium is loaded into the storage device, reproduced and transmitted for a predetermined time based on a reproduction command, and then returned to the shelf 1 after completion of the reproduction. When the device is given a command to insert a blank event to stop playback/transmission operation, it inserts a blank event immediately before the event for which the playback/transmission start time STT is input, and sets the playback/transmission time D of this blank event.
Assigning the time calculated from the time information of a plurality of preceding and succeeding events as U, and assigning the actual elapsed time of the blank event to the reproduction transmission time D specified on the reproduction transmission list 20.
Different display modes are displayed on the display device 14 depending on whether or not U is exceeded.

When an F effect blank event insertion command is given, a blank event is automatically inserted before the event for which the reproduction transmission start time STT is input. Therefore, by giving an insertion command, the operator can create the playback and transmission list 20 for blank events without having to perform input operations in advance.

In this way, the playback and transmission time DU of the blank event listed on the list 20 is determined from the time information of the preceding and succeeding events. Therefore, even if there is a time conflict at the time of input, the reproduction/transmission list 20 can be made free from the time conflict by performing the insertion operation.

Since the blank event input in this way is different from the time information input directly by the operator, it may differ from the desired time. Therefore, it is possible that the elapsed time of a blank event exceeds the playback/sending time on the list 20, and different displays are displayed depending on whether it exceeds the time or not.

G example (G1) Example Hereinafter, an embodiment of the present invention will be presented with reference to the drawings.

In FIG. 2, reference numeral 20 indicates a playback and sendout list, and the playback and sendout list 20 includes items such as the playback number NO, which has a different serial number for each event, and tape cassette 2.
ID signal ID of the title, etc. related to the event, playback and transmission start time at which tape cassette 2 is played and transmission starts as an output signal of the cart machine (time at which broadcasting is to be started by the subsequent broadcasting device) STT, from tape cassette 2 Playback transmission time (broadcast time) DU that outputs the playback signal of
It has a shelf number BN for storing one tape cassette 2, a VTR number VT for loading the tape cassette 2, etc.

The reproduction transmission list 20 includes, for example, transmission number No. “34”;
As shown in "37", in order to broadcast the video signal from the television camera device or the video signal from another cart machine, the blank period during which the cart machine stops playing and transmitting operation (hereinafter referred to as blank event) ) is organized by listing. Also, playback transmission list 2
The playback transmission start time STT at 0 is stored for each event, but in order to make the display easier to read, only the event for which the operator manually inputs a key is displayed.

The control device 8 controls the ejection, loading, ejection, and playback loading of the tape cassette 2 based on the playback and sending list 20,
When reproduction and transmission of a certain event is completed, that event item is deleted from both the reproduction and transmission list stored in the buffer memory 9 and the reproduction and transmission list displayed on the display device 14. Therefore, the event picked up in the top row of the reproduction/sending list 20 (hereinafter referred to as the top event) becomes the event that is to be reproduced or is currently being reproduced.

When the control device 8 receives a blank event insertion command from the operator via the input device 10, for example, it executes the blank event insertion program shown in FIG.

That is, after the program is started in step SP1 by the operator's operation, the top event is set as the event to be processed in the next step SP2. Then,
In step SP3, it is determined whether the event to be processed is an event for which the playback transmission start time STT should be displayed.

If a negative result is obtained, the next event is set as the event to be processed in the next step SP4.
Proceed to step 5. This step SP5 is a step for determining whether or not the event is the next event (hereinafter referred to as the designated event) after the event previously designated as the last event to be processed by the operator. If a positive result is obtained, In step SP6, the duty pig program is ended, and if a negative result is obtained, the process returns to step SP3, and it is determined whether or not the event to be processed is an event for displaying the reproduction transmission start time.

If a positive result is obtained in this step SP3, the process proceeds to step SP7, where it is determined whether the event before the event to be processed is a blank event.

As a result, if a negative result is obtained, the process proceeds to step SP8, where the time obtained by adding the reproduction and transmission time to the reproduction and transmission start time of the previous event is calculated and temporarily stored in the buffer. Thereafter, in step SP9, a blank event is newly provided before the event to be processed, and the process proceeds to step 5PIO, where the time stored in the buffer is set as the playback/transmission start time of this blank event. After that, the process advances to step 5P11.

Further, if a positive result is obtained in the above-mentioned judgment step SP7 because the previous event is a blank event, the process immediately proceeds to step 5pit. In step 5 PII, the difference time between the playback start time of the blank event that existed beforehand or the playback start time of the processing target event is calculated and temporarily stored in the buffer, and in the next step 5P12, this difference is calculated. Let time be the playback and transmission time of the blank event. Thereafter, the process returns to step SP4 and the next event is set as the event to be processed.

Therefore, for example, as shown in FIG.
For example, the reproduction transmission start time of event number "24" obtained from the event before J is "OO:01:OO", and the reproduction transmission start time entered by the key is r00:01:30.
In a case different from J, when the program is executed by the operator's selection operation, steps SPI and SF3 are executed.
After passing through, the loop of steps 5P3-3P4-3P5-3P3 is repeated until the event becomes event No.24J. In addition, the specified event is Event) No r24
It is assumed that it is set after J.

When the event to be processed becomes Event 1-NOr24J,
A positive result is obtained in step SP4, and step S
After PY, at step SP8, time roO:01:
OOJ is stored in a buffer.

After that, a blank event is inserted in step SP9, and therefore, event NOr24J becomes a blank event, and the previous events Nor24J, "25", etc.
... become "25", "26", etc., respectively. Thereafter, roo:01:OOJ is stored as the reproduction transmission start time of the blank event No. 24J (note that it is not displayed).

By going through steps 5PII and 5P12, the playback transmission start time r00 of the processing target event) No r25 is determined.
:01:30J and blank event N.

The playback and transmission start time of “24” is roo:ot:o.

'' and the difference time r00:00:30J is determined, and this is stored and displayed as the playback transmission time DU of the blank event N0r24J, as shown in FIG. 3(B).

Thereafter, the same operation is repeated, and the playback transmission start time ST
A blank event is inserted before the event where T is displayed on the line (.

Therefore, according to the above-described embodiment, when an operator creates the playback/transmission list 20, the operator does not have to input information regarding a blank event, but only needs to input the playback/transmission start time STT of the next event. By executing the playback transmission list 20,
Input operations can be simplified.

Incidentally, in the case of a blank event, the broadcasting device is switched to another cart machine or television camera device, so the reproduction transmission start time STT of the event following the blank event has an important meaning. Since it is desirable to display the event, it is often done manually, and even if the user is required to enter the playback start time STT of the next event in order to insert a blank event, the operation will be more complicated than in the past. This does not lead to problems, and the operation is simplified by not having to input blank event information.

Also, if you do not intend to insert a blank event,
An event in which the playback transmission start time STT is keyed manually,
If there is a time conflict with the previous event, a blank event is inserted and a complete playback and transmission list 20 can be obtained.

By the way, as mentioned above, it is not necessary to input the time to switch to another cart machine or television camera device (playback transmission time DU of a blank event). Since the reproduction and transmission time of a blank event is determined by the following, for example, a time conflict may occur with the reproduction and transmission list 20 of another cart machine.

Therefore, the disconnection between the cart machines is not properly performed, and the reproduction transmission start time S of the next event after the blank event is delayed.
Even after reaching TT, the command to play the next event was not given,
There is a possibility that reproduction and transmission will not be performed.

Therefore, the cart machine that inserts a blank event by executing the program shown in FIG. It is designed to be executed every second).

That is, after starting the program in step 5P20, in the next step 5P21, it is determined that the tape for the previous event has ended beyond the playback sending end point (end op message point) ROM! After the event is confirmed, the process proceeds to the next step 5P22, and it is determined whether the event is a blank event or not.

As a result, if it is not a blank event, the process proceeds to step 5P28 and subsequent display processing, and if a positive result is obtained,
In the next step 5P23, positive numbers, negative numbers (
The sign flag indicating a negative number (including 0) indicates a negative number (logical rlJ
). As a result, specify a positive number (
If it is determined that the logic is "0"), step 5P
In step 24, the reproduction transmission count number is decreased by rlJ.

Here, the reproduction transmission count number is set in advance when the blank event before the blank event ends and the cart machine is switched to the corresponding cart machine, and is a value representing the reproduction transmission time of the blank event in number of frames. is set.

When the process of step 5P24 is completed, step 5P2
5, it is determined whether the count number has decreased to "0" or not. If a negative result is obtained because the value is not "0", the process proceeds to step 5P28 and subsequent display processing.On the other hand, if a positive result is obtained because the value is rOJ, the sign flag is changed to a logic value representing a negative number in step 5P26. 1", then proceed to display processing.

In step 5P23 described above, if a positive result is obtained because the sign flag indicates a negative number, the process proceeds to step 5P27, where the playback/transmission count (1 to value) is incremented by 1, and then the process proceeds to step 5P28.

Step 5P28 is a step of determining whether or not the sign flag indicates a negative number. If a positive result is obtained as a result, the process proceeds to step 5P29 and the playback transmission count number at that time is displayed on the display screen DBS on the display device 14. The program is inverted and displayed in the transmission count display area API, and the program is terminated in step 5P30.If a negative result is obtained as a result of the determination in step 5P28, the process advances to step 5P31 and the reproduction transmission count at that time is displayed. The number is displayed in the normal display mode (display mode for reverse display) and the program is ended in step SP30.

Therefore, according to this program that is started every frame, when switching to a blank event and switching to another cart machine or television camera device, the display screen D
The reproduction transmission count displayed on the ES decreases by "1" for each frame, and when the reproduction transmission time DU of the blank event specified in the reproduction transmission list 20 has elapsed, the count number becomes "0". ”.

Even after the specified playback transmission time DU has elapsed, the cart machine or television camera device in the pond does not switch to the cart machine, and even after switching, the playback command for the next event is not given. The count increases by "1" in accordance with the time that exceeds the playback/transmission time, and is displayed in reverse video.

Accordingly, by following the monitoring program, the operator can easily recognize when the blank event time (reproduction/transmission time) exceeds the predetermined time, and can take appropriate measures.

(G2) Other Embodiments and Modifications It should be noted that the following processes may be executed in correspondence with the processes shown in FIGS. 1 and 4.

(1) For example, as shown in Figure 2, if the top event N0r31J is an event in which the playback start time STT has been input manually, if the program shown in Figure 1 is executed, the top event will have an indefinite playback start time. Blank events are listed.

Therefore, when this playback and sending list is loaded and executed, the difference between the playback and sending start time of the next event and the actual time at the time of loading is assigned to this blank event as the playback and sending time, and the actual time is set to Try to match it.

(2) As shown in FIG. 2, the event before the event for which the playback/transmission start time STT was entered manually before insertion may already be a blank event. When the program shown in FIG. 1 is executed for such a playback/transmission list 20, two blank events will follow.

In this case, the playback transmission time DU of the subsequent blank event is “0”.
”.

Therefore, the subsequent blank event may be regarded as a normal event, and the switching operation to another cart machine or television camera device may not be activated.

Additionally, blank events for other cart machines and blank events for the television camera device may follow. In this way, if blank events with reproduction transmission time DU other than "0" continue, when the count number reaches rOJ by executing the program in Figure 4 for the previous blank event, the next blank A count number corresponding to the reproduction and transmission time of the event may be set.

(3) Save the program shown in Figure 1 to an external memory device! ! ll
It may also be configured to be automatically executed when the data is transferred from the file to the buffer memory 9. In this case, since the last event is the specified event, overflow may occur due to the insertion of many blank events. Therefore, the occurrence of overflow may be notified, and the insertion process may be performed within a range that does not cause overflow.

(4) Since a time conflict may occur between the reproduction and transmission list of each cart machine and the reproduction and transmission list of the host computer that controls multiple cart machines as a whole, starting the program shown in Figure 1 It may be possible to enable not only automatic activation but also manual activation, so that the operator can arbitrarily select as necessary.

(5) The present invention can be applied not only to cart machines that use magnetic tape (tape cassette) 6 as a video signal recording medium, but also to cart machines that use video disks.

H Effects of the Invention As described above, according to the present invention, blank events can be automatically inserted into the playback and transmission list, thereby improving the operability of creating and inputting the playback and transmission list. , it is possible to obtain a playback and transmission list that is consistent in time.

Furthermore, since the actual time of the blank event is monitored and a notification is made when the scheduled time is exceeded, the operator can take appropriate measures.
