However, in the area of the audio signal (monaural) 56, digital information from the workstation is passed through the modem 25, converted into an audio signal, and recorded. Specifically, as will be described later, the workstation records marks and times when the screen stopped moving.

FIG. 5 is a block diagram showing the internal structure of the VTR controller 22 explained in FIG. 1. This is also a type of computer, with a CPU 22-1, memory 22-2, RO
It is composed of M22-3, RAM22-4, etc. The functions of each of these parts are the same as those of the CPU, memory 2, ROM 3, and RAM 4 explained on the workstation side in FIG. 1, and their explanations will be omitted here. Here, CPU2
In addition to the memory 22-2, 2-1 has a memory on the workstation side (

Control. Start up the rVTR device main body 20 in the flowchart of the program on the workstation side.
Actually, this means that the VTR controller 22 is commanded to start up the VTR device main body 20.

FIG. 6 shows a transmission path for recording signals and reproduction signals exchanged between the workstation shown in FIG. 1 and the VTR device 20. The recording signal from the workstation side is delayed by about 2 seconds by a VTR signal delay device 21, and then sent to the VTR device 20 for recording. Similarly, during playback, the playback signal from the VTR device 20 is delayed by about 1 second by the VTR signal delay device 21, and is sent to the workstation and played back as a video.

FIG. 7 is a diagram showing an example of the internal structure of the VTR signal delay device 21. As shown in FIG. 60 is an endless VTR tape, 61 is a rotary head for recording, and 62 is a rotary head for playback. The length of the endless tape 60 is adjusted so that it rotates once in about 2 seconds, and by recording and playing back on the tape 60 simultaneously, delay of the VTR signal is realized. However, since this tape 60 must continue to rotate while the power of this embodiment is turned on, there is a problem with the durability of the tape 60, and also, there is a problem in the durability of the tape 60. Furthermore, V
This method requires a TR system, and the video quality is severely degraded, making this method of signal delay impractical.

Therefore, by using the circuit shown in Figure 8, the VTR can be stored in a large capacity memory.
A delay device 21 that stores signals and delays VTR signals is realized. In the figure, 63 is a video signal, an audio signal (left), and an audio signal (right).

Large capacity memory for recording audio signals (monaural),
64 is a video signal writing circuit for writing a video signal into the large capacity memory 63, and 65 is a video signal reading circuit for reading out the video signal written in the large capacity memory.

The large capacity memory 63 has a capacity large enough to record approximately 2 seconds worth of video signals.

Further, the circuit shown in FIG. 8 shows that during recording, the workstation side is the input and the VTR side is the output, and during playback, the VTR side is the input and the workstation side is the output.

FIG. 9 is a diagram showing the division within the large-capacity memory 63, in which the video signal, audio signal (left), audio signal (right), and audio signal (monaural) are each placed in separate areas and divided into time zones. The total time is set for about 2 seconds. During operation, this VTR signal delay device 21 points to the write pointer 66.
At the same time as each VTR signal is written to the designated position, each VTR signal at the designated position of the read pointer 67 is read out.

Moreover, as time passes, the write pointer 66 and the read pointer 67 continue to move in parallel while maintaining a constant interval.
When it reaches the end of the memory, it moves to the beginning of the memory again and continues to generate a delay signal forever until a stop command is received.

FIG. 9(a) shows the relationship between the write pointer 66 and the read pointer 67 during recording, and there is an interval of 2 seconds between the two pointers. In addition, Fig. 9 (b
) represents the relationship between the write pointer 66 and the read pointer 67 during playback, and there is an interval of 1 second between the two pointers.

Figure 10 shows the RA in memory 2 on the workstation side.
This figure shows the configuration of the database software loaded on the M4 in memory. The memory area 70 includes, from the bottom, an operating system (hereinafter referred to as O8), a Japanese front end processor 72 used for inputting kanji, database software 73, and a work area 77.

The work area 77 is mainly used by the database software 73. The database software 73 further includes a database main program 74 and a recording program 7.
5. It is composed of a reproduction program 76.

The recording program 75 is the database main program 7
Controls the work of recording the movements on the screen of step 4 on the VTR device body 2°. Here, the database main program 74 is in a multitasking format that operates independently and simultaneously in parallel, and constantly monitors whether the database main program 74 is running or stopped, and when the screen movement stops, It has a function to interrupt recording to the VTR device main body 21 after a second has elapsed. Also, if there is movement on the screen while recording is interrupted, it will issue a command to resume recording.

The playback program 76 is a VTR in the VTR device main body 2o.
This is a program for playing cassettes. From the database main program 74 according to the user's instructions,
Since the processing is transferred to the playback program 76 and the playback operation begins, the database main program 74 and the playback program 7
6 does not have a multitasking format.

The application software that can be run on the apparatus of this embodiment, which is comprised of a workstation and a VTR, is basically comprised internally of three parts: a main body program, a recording program, and a playback program.

Therefore, screen movements caused by all applications are
It becomes possible to record on a VTR.

FIG. 11 shows a part of the initial setting files config and vdb when the database software 73 is started. Settings include the presence or absence of a status line, the name of the database menu to be started first, the color display mode of the screen, the name of the screen editor program used internally, the name of the word processing software used internally, and whether or not to record to a VTR. If rVTR=ONJ, the mode will be such that it is possible to record and play back the screen operations of the workstation, which has been explained so far using the example of a single real family, but if rVTR=O
In the case of FFJ, the mode is set in which only the database main program 74 operates, assuming that there is no recording or playback on the VTR from the beginning.

Figure 12 shows the prompt (
〉) The following shows a scene in which the startup command name rVBASEJ of the database software 73 is entered manually. After this, the database software 73 is loaded and execution begins.

FIG. 13 shows the screen immediately after the above-mentioned database software 73 is started, and requests the operator to enter a name and password. 80 indicates a character cursor;
The operator uses the keyboard 10 to input characters from this position.

Next, FIG. 14 shows the screen displayed next after the input of the operator name and password shown in FIG. 13 is completed. Here, the operator selects a menu for VTR playback, database execution while VTR recording, etc., and enters each process.

Note that this screen displays the initial settings file conf mentioned above.
This is displayed only when rVTR=ONJ is set in ig and vdb.

If rVTR=OFFJ, the state shown in FIG. 13 suddenly shifts to the database actual processing screen shown in FIG. 19.

Figure 15 is the number “1” or “2” in Figure 14 above.
This shows a cautionary window explaining the playback procedure that is displayed when you select .

Basically, playback is performed using only the remote control 26.
After waiting 10 seconds in the state shown in FIG. 15, the display on the CRT display 6 automatically changes to the reproduced image of the VTR tape.

Initially, the image is in a still image state, from which the operator performs playback operations using rewind, fast forward, and playback buttons. Here, if the stop button 43 is pressed twice, the screen returns to the recording/playback menu screen shown in FIG. 14. Note that details will be explained in the flowchart described later.

By the way, "subdivided playback" shown in FIG. 14 means that when recording a workstation screen, if there is no movement on the screen, that part is cut and the recorded video on the VTR tape is played back as is. In other words, when playing,
Extra scenes with no movement are cut out, so the playback time is shortened. Also, "Full time playback" means that when recording the workstation screen, if there is no movement on the screen, that part will be cut. The scene is then recorded on a VTR tape, but at the same time the time of the cut scene is also recorded, so when playing back, the cut part is displayed on the VTR tape for the length of the still image. This refers to replaying the entire time, including cut scenes.

In other words, unnecessary parts on the VTR tape are cut,
Although it is saved, when playing, the entire time is played, including the time when the screen is static.

For details on how to record the cut time, see Section 20 below.
Details will be explained with reference to the drawings.

Figure 16 shows the number "3" in the recording/playback menu in Figure 14.
” is a diagram showing a screen displayed when “ is selected.
It shows a window that describes the recording procedure. This screen explains the procedure for determining the recording position on the VTR tape by operating the buttons on the remote control 26. During this recording position determination work, the process is the same as that shown in FIG. 15 above (the CRT display 6 displays the VTR tape being played back. Also, when the stop button 43 is pressed twice, the process moves to the next step in FIG. 17).

FIG. 17 shows the work for recording the video recording title before starting the actual work of the database. Whether or not to insert a title at the beginning of the recording, if a title is included, title 1
The date and time, operator name, and memo are input using the keyboard 10. FIG. 18 is an example of a screen when the recording title is actually entered manually. In this case, the VTR
This title screen is first recorded on the tape,
Recording of the actual database work will continue from 10 seconds later.

Next, FIG. 19 shows the main menu screen for actual work on the database. Here, - see.

Select and execute registration, modification, deletion, etc. The operation from this point on is the same as that of a normal database, so the explanation will be omitted.

Note that if "9" is input here, the database processing is interrupted and the screen returns to the recording/playback menu shown in FIG. 14. Also, if you are processing the database while recording, "9°.

If you input , recording will be interrupted and the rotation of the rotary head will also stop. However, if "0" is entered, the database ends. Also, while recording is in progress, a recording end mark appears on the VTR tape, recording ends, the rotation of the rotating head also stops, and the display on the CRT display 6 changes to the O8 prompt display shown in Figure 12. be returned to.

FIG. 20 shows the temporal positional relationship of interruption mark information stored in the VTR tape audio (monaural) area. To explain step by step, VTR tape 5
1 starts with recording the recording title for about 10 seconds, but the first thing recorded in the audio (monaural) area 56 is the recording start mark.After that, the video 53 starts with the main menu display of the database. After doing so, a list of data is displayed according to the operator's selection.

Here, the operator pauses the operation of the workstation in order to check the slip to be corrected, and when 5 seconds have passed since the screen stopped moving, the recording program 75 starts recording the VT.
The recording of the R device body 2o is interrupted and the rotating head is also stopped.

After that, when the operator resumes data correction work on the workstation, immediately after that, the recording program 75 starts up the VTR device main body 20 and starts recording two seconds later, but at the same time as the recording starts, the audio (monaural) 56 area Record the interruption mark and the interruption time of 1 minute 35 seconds. After that, the interruption mark is 1 hour 5 minutes 13 seconds due to the operator's lunch break, and the interruption mark is 33 seconds due to the operator checking the customer list. After that, the corrections and new registrations on the database are completed, and the operator When "0" is selected from the main menu, the recording program 75 puts a recording end mark in the audio (monaural) area 56, then stops the VTR device main body 20 and also stops the rotation of the rotary head. O8
You will be returned to the prompt.

In addition, even if the two records of each interruption mark and interruption time are combined, they are each within one second. This is because when playing back later, if various controls are performed based on this information, if this recording time is too long, the time lag between reading and the start of control will be too large, leading to confusion. This is because of its nature.

Next, the control procedure in this embodiment will be explained below according to a flowchart.

FIG. 21 explains the control procedure of the database main program 74 in the database software 73. By the operation shown in Fig. 12, the database software 7
3 is started, first, in step S-1, the operator name and password input screen explained in FIG. S3
Proceed to processing. In step S3, the operator tries to stop the work and inputs rCTRL+CJ from the keyboard IO.
If the answer is YES, the process ends and returns to the O8 prompt display state. However, N
If it is O, the process advances to step S4, and it is checked whether the input operator name and password are correct. Here, if NO, the process returns to step S2, and the operator is prompted to input the operator name and password again.

However, if YES, the process advances to step S5 and the network connection device 15 is used to connect to the network 16. Then, in the next step S6, the recording/playback menu screen shown in FIG. 14 is displayed, and in the following step S7, a menu selection by the operator is awaited. After entering the information,
The input is determined in step S8 and subsequent steps, and each process is executed.

Here, if the menu selection by the operator is "O" (end), the process advances to step SIO, and the network 16
The network connection device 15
, return to the O8 prompt display state, and exit. However, if the operator's menu selection is "l" (subdivision generation), the process advances from step Sll to step S13. If the menu selection is "2" (full time playback), the process similarly advances to step S13, opens the playback procedure explanation window explained in FIG. 15, displays it for 10 seconds, and then displays the playback screen in step S14. automatically moves to. Initially, the image is in a still image state.

In step S14, the recorded VTR video is displayed on the CRT display 6 according to the operation of the remote control 26 by the operator. This process is executed by the control procedure of the reproduction program 76.

The details of this reproduction program will be explained with reference to the flowchart of FIG. 23, which will be described later. When the operator presses the stop button 43 on the remote control 26 twice in step s14, the process exits step S14 and returns to the recording/playback menu screen display in step s6.

Menu selection in step S7 is 3″ (recording/execution)
If so, the recording procedure window shown in FIG. 16 is displayed in step S17. In the next step S18, a recording start position on the VTR tape is searched in accordance with the operation of the remote controller 26 by the operator. During this search, the CRT display 6 displays a reproduced image such as a high-speed search of a VTR tape. Next, in step S19, it is checked whether the operator has pressed the stop button 43 twice, and the operator presses the stop button 43 twice.

If so, return to step 318 and continue searching for the recording start position on the VTR tape; if YES, step S2
0, and the window for inputting the recording title shown in FIG. 17 is displayed. In step S21, if the operator wishes to record a recording title, input the title from the keyboard 10.

Enter date and time, operator name, and notes.

Next, in step S22, "1. Execute recording with title" or "2. Execute recording without title" is selected, and the result is determined in step S23 and step S26. If the result is "1" (with title), the process advances to step S24, and the recording program 75 is instructed to start recording. Next, in step S25, the above-mentioned recording title is displayed (FIG. 18) for the first 10 seconds. The details of the recording program 75 will be explained with reference to the flowchart shown in FIG. 22.

On the other hand, if the operator selects '2' (no title), the process proceeds from step S26 to step S27, starts the recording program 75, and starts recording.
After the processing in step S25 or step S27, the process advances to step S29, and the main menu of the database shown in FIG. 19 is displayed.

Further, in step S7 described above, the operator selects "4" (
If "Execution without recording" is selected, the process advances from step S28 to step S29, and the main menu of the database is displayed. Step S29 and subsequent steps describe the actual processing of the database. In step S29, the operator's menu selection is awaited. First, in step S30, 'O
” (Exit) is selected. If YES,
Proceeding to step S9, the recording program 75 is commanded to end recording, and in the next step SIO, the network connection is canceled and the prompt display state of O8 is returned to, thereby terminating the entire database processing. If NO in step S30, the process advances to step S31, and it is checked whether the operator has selected "l" (-list display), and if YES, step S31 follows.
At step 32, according to the operator's instructions, display a list of data,
Register, modify, and delete data. Thereafter, when the process is completed, the process returns to step S29 to display the main menu of the database.

If No in step S31, proceed to step 333,
Check whether the operator has selected "2" (display each item), and if YES, in step S34, according to the operator's instructions, display each data item, and further register, modify, and
Perform deletion, etc. When the process is completed, the process returns to the database main menu screen display in step S29. However, if No in step S33, the process moves to step S35, and it is checked whether the operator has selected "3" (search). If YES, the process moves to step S36, and data search is performed according to the operator's instructions. When the processing is completed, the process returns to step S29 to display the main menu of the database.

Further, if NO in step S35, the process moves to step S37 and checks whether the operator has selected "'4" (other). If YES, in step 338, according to the operator's instruction, the process defined as "other" is executed. Execute. When the processing is completed, the process returns to step S29, where the main menu of the database is displayed. If NO in step S37, the process moves to step S39, and the operator selects "9" (
If YES, the program instructs the recording program to end recording in step S15, and then proceeds to display the recording/playback menu in step S6. but,
If NO, the process returns to step S29 to display the main menu of the database.

Next, FIG. 22 is a flowchart showing the control procedure of the recording program 75. As mentioned above, the recording program 76 after startup is processed simultaneously and in parallel as a multitask independently of the database main program 74, and is dependent on the operator's input from the keyboard 10 and the execution processing status of the database main program 74. monitor,
It performs various controls such as starting recording and interrupting recording for the VTR device main body 20. The process will be explained below according to the flowchart.

From the database main program 74 to the recording program 7
When the startup command 5 is issued, first step S4 is executed.
0 starts the VTR signal delay device 21. that time,
Human power is placed on the workstation side, and output is placed on the VTR side. Furthermore, the time difference between the input signal and the output signal is set to 2 seconds. Next, in step S41, a startup command for the VTR device body 2o is output, and in step S42, the audio (monaural)
Insert the recording start mark signal into the band. At this point, this signal is still stored in the VTR signal delay device 21. Now moving to step S43,
Wait 2 seconds from the startup command until the VTR device main body 20 becomes ready for recording.

This 2 seconds is necessary for tasks such as increasing the rotation of the rotary head.

After 2 seconds have elapsed, recording is started in step S44, and at the same time, the variable T is set to '0.1' and the variable W is set to '0'.Next, in step S45, the database main program 74 Check whether a command to end recording has been received from.

This end command is issued from step S9 or step S15 shown in FIG. 21, but if YES here, the process moves to step S46, a recording end mark signal is input to the audio (monaural) band, and step S47 This 2 seconds is the time during which all the signals accumulated in the VTR signal delay device 21 are recorded in the VTR device body 20. Then, the process moves to step S48, and the VTR
The device main body 20 is stopped, and the rotation of the rotary head is also stopped, and in the following step S49, the VTR signal delay device 2 is stopped.
1 is also stopped and the program returns from the recording program 75.

If NO in step S45, the process proceeds to step S50, where it is checked whether the operator pressed any key from the keyboard 10. If YES, the process proceeds to step S52. If NO in step S50, the process proceeds to step S50.
51, it is checked in the database main program 74 whether processing such as database search is in progress. If the result is YES, it is the same (proceeds to step S52. In this step S52, it is checked whether the variable W is "1", that is, recording is being interrupted. If YES, the process proceeds to step S53, and a command to start up the VTR device main body 20 is issued. In step S54, an interruption mark signal and an interruption time T second mark signal are input to the audio (monaural) band.

In the next step S55, the CPU waits for two seconds from the start-up command until the VTR main body 20 becomes capable of recording, and then resumes recording in step S56. At the same time, variables T and W are each set to "0", and the process advances to step S60. On the other hand, if NO in step S52, the variable T is set to "0" in step S57, and then the process proceeds to step S60.

Also, if NO in step S51, step S58
Add "0.1" under the variable in step S59, and add "0.1" under the variable T in step S59.
is 5.0" or more, and if NO, the process proceeds to step S60. In this step S60, "O, l'
After waiting for a second, the process returns to step S45 and repeats the above-described process. Further, if the variable T is "5.0" or more in step S59, the process advances to step S61, and it is checked whether the variable W is "1", that is, recording is being interrupted. Here, if YES, step S
If the answer is NO, the process waits for 2 seconds in step S62, and then in step S363, the VTR device main body 20 is stopped, and the rotation of the rotary head is also stopped.

Next, in step S64, after setting the variable T to °°0°° and setting the variable W to "1", the process proceeds to step S60 described above.

The reason for waiting 2 seconds in step S62 described above is that before stopping the VTR device main body 20, all 2 seconds worth of signals stored in the VTR signal delay device 21 are
This is because it is recorded in the TR.

As explained above, the flowchart of the recording program 75 can be summarized as follows.

This means that the workstation screen becomes static and
V
TR stops. Thereafter, when the operator starts pressing the key again, recording on the VTR is immediately resumed, and the above-mentioned monitoring action is constantly repeated.

[Margin below] FIG. 23 is a flowchart showing the control procedure of the reproduction program 76. This is a process that describes the details of step S14 shown in FIG. 21(b). Note that the playback program 76 does not operate in a multitask manner like the recording program 75 (it is called as a normal simple subroutine).

When the playback program 76 starts, first, in step S71, the VTR signal delay device 21 is activated. The conditions are that the input is on the VTR side, the output is on the workstation side, and the time difference between the input signal and the output signal is 1 second. In other words, the recording input and output directions are reversed.

In addition, the video signal, audio signal (left), and audio signal (right) are
Although signal delay processing is applied, only the audio signal (monaural) passes from the input side to the output side without signal delay. This is an audio signal (monaural) that is generated prior to the video being played.
This is because it is necessary to read out the information about the interruption mark and interruption time recorded in the disc to control playback. This point also differs greatly from the case of recording.

Next, in step S72, a command is given to start up the VTR device main body 20, and in step 573, the process waits for 2 seconds.

Wait until playback is possible, such as by increasing the rotation of the rotating head. Then, in step S74, the display on the CRT display 6 is changed from the display on the workstation side to V
Switch to video display from the TR side. At this point, V
Although the TR tape is not running, the rotary head has reached steady rotation and the display is already in a still image display state. However, care must be taken because if this still image state continues for more than a few minutes, the surface of the VTR tape will be damaged.

Next, in step S70, it is checked whether the operator has pressed the rewind button 41, fast forward button 42, or play button 40 on the remote control 26. Here, NO
In this case, the operator operates the remote control 26 in step S75.
It is checked whether the stop button 43 has been pressed, and if NO, a loop is formed immediately before step S70. YE
If S, the process moves to step S76, and it is further checked whether the operator has pressed the stop button 43. If NO, a return loop is formed just before step S70, but if YES
If so, the process moves to steps S77 and subsequent steps for completing the reproduction work. That is, in step S77, the display on the CRT display 6 is switched from the VTR video display to the workstation signal display. At this point, the display changes to the recording/playback menu shown in FIG. Then, in step 378, V
The TR device main body 20 is stopped, the rotation of the rotary head is also stopped, and (in step S79, the VTR signal delay device 21 is stopped).
The program also stops and returns from the reproduction program 76.

If YES in step S70 above, step S8
0 and checks whether the button pressed by the operator is the rewind button 41.

If YES, in step S81, the VTR device main body 20 is commanded to rewind in high-speed search mode, and the process proceeds to the next step S8.
Rewinding continues until it is determined that the operator presses the stop button 43 at step 2.

If you can determine that you pressed this stop button 43,
In step 5IOI, the VTR apparatus body 20 is brought into a still image state, and the process returns to immediately before step S76.

If NO in step S80, the process advances to step S83, and the button pressed by the operator is the fast forward button 4.
Check if it is 2, and if YES, V in step S84.
The TR device main body 20 is commanded to perform fast forwarding in high speed search mode. In step S85, the operator presses the stop button 43.
If it is determined that the stop button 43 has been pressed, the process moves to step 5IO1, the VTR main body 20 is put into a still image state, and the process returns to immediately before step 376.

If NO in step S83, the processing performed when it is determined that the operator has pressed the playback button 40 after step S86 is executed. In step 886, it is checked whether the playback mode is subdivided playback mode, and if YES, the VTR device main body 20 is commanded to play back in step S87. In the next step S88, playback is continued until it is determined that the operator has pressed the stop button 43.
If it is determined that the message has been deleted, step 5101
In step S7, the VTR device main body 20 is set to a still image state.
Go back to just before 6.

If No in step S86, proceed to step S89,
The playback mode executes processing in full-time playback mode. First, the VTR device main body 20 is commanded to reproduce, and in step S90, checking of interruption mark data recorded in the audio signal (monaural) is started. As mentioned above, VTR
Video signal, audio signal (left), audio signal (right) on tape
is input to the VTR signal delay device 21 and output to the CRT display 6 etc. after a time delay of approximately 1 second, while only the audio signal (monaural) is passed to the workstation side without time delay. , to be analyzed.

Note that the total length of the interruption mark and interruption time recorded in the audio signal (monaural) is less than one second, and the recording of the interruption mark and the like can be pre-read before displaying the video. This point is also as mentioned above.

If the answer is No in step S91, the process proceeds to step 5100, and checks whether the operator has pressed the stop button 43 on the remote control 26. If the answer is no here, the process returns to step S90 to form a loop, and checks whether there is an interruption mark. Repeat.

However, if YES in step 5100, the VTR apparatus body 20 is brought into a still image state in step 5IO1, and then the process returns to step S76. Also, if you select Y in step S91,
In the case of S, the process proceeds to step S92, the movement of the write pointer 66 and read pointer 67 in the VTR signal delay device 21 is stopped, and in the next step S93, only the same screen is read out. With this, it is possible to continue outputting and displaying still images regardless of the VTR device main body 20. Then, in step S94, the VTR device main body 20 is stopped, and the rotation of the rotary head is also stopped.

Next, in step S95, it is checked whether the length of the interruption time attached to the interruption mark checked in step S91 has elapsed, and if NO, step S96
It is checked whether the operator has pressed the stop button 43. If not, step S95
It loops back to and continues checking whether the interruption time has elapsed.

Here, if it is determined that the interruption time has elapsed, the process proceeds to step 5102, where a startup command is issued to the VTR device main body 20, and in step 3103, the VTR device main body 20 becomes capable of playback, such as by increasing the rotation of the rotary head. Wait 2 seconds until Then, the process returns to step S89 and reproduction is resumed.

At this time, the movement of the write pointer 66 and the read pointer in the VTR signal delay device 21 also resumes.

In other words, in full-time playback mode, in addition to simply playing back the video on the VTR tape, the interrupted portions are played back for the interrupted time.
The entire time of recorded video is reproduced by sending still images from a VTR signal delay device 21.

If YES in step 596, the process proceeds to step S97, where a command to start up the VTR device main body 20 is issued, and in step 398, the rotation of the rotary head is increased, etc., and the wait is for 2 seconds until the VTR device main body 20 is ready for playback.Step S9
At step S9, playback is started, and at step S5IOL, the VTR apparatus main body 20 is put into a still image state, and the process returns to immediately before step S76.

Also, at step S99, the write pointer 66 and the read pointer 67 in the VTR signal delay device 21
resume the movement.

Note that the still image state in step 5IO1 is a state in which the tape in the VTR main body 20 has stopped, but the rotary head is rotating normally and continues to send signals. In this case, the write pointer 66 and the read pointer 67 in the VTR signal delay device 21 continue to move and continue to output a signal delayed by one second. However, since only still image signals are received from the VTR main body 20, the display remains stationary. In this still image state, the rotary head continues to rub against the stopped VTR tape for a long time, so care must be taken that the tape will be damaged if this continues for more than a few minutes.

On the other hand, the method of continuing to send still images from the VTR signal delay device described in step S93 simply continues sending signals from within the large-capacity memory, so there is no need to worry about damage to the tape or equipment even if the still image state continues for a long time. do not have.

The above describes the database registration/modification by the operator.
The overall operation of this embodiment has been explained using the browsing/deletion work as an example. However, if records are kept in ■TR° in this way, it will be easier for a person in charge of managing a large number of operators to It is easy to later investigate when and how the operator made a mistake in what part of the input, or where the operator intentionally corrected it. The stationary parts on the VTR tape are cut out, so they are recorded later on the VT tape.
Search on R tape can also be done quickly.

In addition, since the cumulative time recorded on the VTR tape becomes the operator's actual operating time, for the administrator,
It is also easy to judge the ability of each operator.

In addition, especially for financial databases where there should be no errors, VT is also used to correct input errors and after they occur.
R recording is absolutely necessary.

[Other Embodiments] In the above embodiment, the workstation screen itself was recorded on a VTR, but if a video camera is provided and connected to the VTR, not only the workstation screen but also the operator's movements can be recorded. be able to.

However, this method has the disadvantage that the movement image on the workstation screen is small and difficult to see during playback.

In addition, although the above-mentioned embodiment has been explained by taking as an example the work of registering, modifying, and deleting a database by an operator, it is also possible to record software development by a programmer, and to port existing software to a different model of workstation. All work displayed on the computer display can be recorded on a daily basis, so even if the person in charge abandons the work due to an accident or the like, the person taking over can easily trace the records.

Therefore, risks caused by human causes in software development plans can be minimized. Also,
Even in long-term work such as software development, the static parts of the screen are cut out and recorded, making it easy to play back and trace back later.

In the above embodiment, VTR recording of software development work was taken as an example, but it can also be used for video recording of information search work in an international database network, for example. Such search work is usually carried out by experts called searchers, but since the database is accessed via the international telephone network, they must make quick decisions in each situation to find the desired data due to telephone charges. Must get it.

In such cases, for example, if you are recording on a VTR, if you get lost during the search process, you can disconnect from the database and play back the recorded VTR to consider it carefully. . Once a policy has been determined, all you have to do is access the database again, which is more efficient in terms of telephone charges. The final data obtained will also be accurate.

Furthermore, in the above-described embodiment, the recording program 75 determines whether to record or not by inputting keys manually from the keyboard 10 or by monitoring the search processing status of the database main program 74. Directly monitors the VRAM 5 that is the source of the display, determines whether there is movement on the display screen, and turns on recording.
You can also decide on FF. In this case, the recording program 75 does not necessarily have to be built into the database software 73; it is not necessary to use only the database software (or the VRAM 5 can be rewritten by multitasking while all other software is running). It is also possible to have a structure that constantly monitors whether or not there is a problem and performs 0N10FF control of recording.

In other words, it can be in the form of independent driver software that is not directly related to the database software.

In the above-mentioned embodiment, the computer synthesized sound output to the left speaker 7 and right speaker 8 on the workstation side as the audio recorded on the VTR is the audio signal on the VTR tape (
(left) and audio signals (right). However, if a microphone is further attached to the workstation so that the operator's real voice can be added over the computer-synthesized sound, computer images can be recorded on a VTR with the operator's annotations and explanations included. This will make the video record even easier to understand.

[Effects of the Invention] As explained above, according to the present invention, when the movement of the workstation display image is recorded on the VTR all day long, if there is no movement on the display, the VTR
This has the effect of saving VTR tape by stopping it and not recording it.

Furthermore, by cutting out parts that do not move, the playback time can be shortened.

On the other hand, when there is no movement on the display, recording is not performed, but the interruption time at this time is also recorded on the VTR tape, and during playback, the period of no movement is not cut, and still images are recorded for the interruption time. Another advantage of sending the program is that it can be played back in its entirety.
