B. Summary of the Invention According to the present invention, recording end information is recorded in management data in an information recording and reproducing apparatus, so that the recording status of each program can be easily checked, and program management can be further facilitated.

C. Prior Art Conventional video tape recorders as consumer information recording and reproducing devices record a cue signal at the beginning of each program when recording a plurality of programs on a longitudinally extending videotape. For example, if a user wants to play back a desired program from a recorded tape, the user first sets the video tape recorder to search mode, fast-forwards the video tape to a position where the cue signal can be played, and then - The user switches to the playback mode and confirms whether the program is the one he or she wants to watch.

Problems to be solved by the invention D However, in this conventional video tape recorder,
Information about multiple programs is recorded for each program only at the videotape location where each program is recorded. Therefore, the user can check the program he or she wants to play, or decide which program he or she wants to play. When searching for a program to play, the user must repeatedly search the video tape recorder to find the program he or she wants to play, which actually involves fast-forwarding the video tape for quite a long time. There is an unavoidable complexity.

In addition, when managing a large number of recorded or unrecorded video tapes, or when managing so-called series programs recorded across multiple video tapes, it is practical to record each video tape separately. The contents of the program,
There is a complication in that the user has to perform management work such as writing management information such as the recording time and whether or not it is necessary to save on the video tape cassette or cassette case in advance.

However, in practice, the time and effort required to write this management information and to read and judge the written management information are complicated, and the degree of complexity depends on the number of programs and video tapes to be recorded or reserved. The more the value increases, the more it is cumulatively weighted, so it is desirable to simplify it as much as possible.

The present invention has been made in consideration of the above points, and when processing programs such as recording and reservation (this is called recording and reservation), it is possible to easily check the recording state of the program recorded on videotape. This paper attempts to propose an information recording and reproducing device that can be verified.

E Means for Solving the Problems In order to solve the problems, the present invention provides recording tracks TA, TB and CHI formed on the recording medium 36.
, CH2 in which one or more programs can be recorded.
Form management database recording areas Fmva and FAVV at predetermined positions on TB, CHI, and CH2, record management data DAv corresponding to the program in the management database recording area FAJA% FAVV, and record end information as the management data DAv. By writing, the recording status of each program can be confirmed based on the management data DAV.

Management database recording areas FAVA, F formed at predetermined positions of one action recording track TA, TB and CHI, CH2
By recording the management data I)Av recorded in the AVV, including recording end information for programs recorded on recording tracks TA, TB, CHI, and CH2, the reserved program can be recorded normally. It is possible to easily grasp whether or not the program has been completed, and the management of each program can be further facilitated.

Further, when the CPU 8 is in the standby state for commands to display the management data list in step 5P21 of FIG.
enters the process of step 5P33, switches the display screen display in step 5P34, and proceeds to step 5P35.
, or 5P36, 5P37, or 5P3B, volume information D□X (Figure 5) and program information @Dpm
x (Figure 6) record contents of "recording permission" item, "seen flag" item, "category" item, and "title" item ti1! The display mode is such that it can be verified or rewritten.

In this example, the "recording permission" item, the "saw flag j"
A predetermined pictorial display, that is, a character, is used as the data for the item, "category" item, and "title" item, which makes it possible to check and change information recorded for multiple reserved programs using a relatively small display area. It has been made possible to do so.

When the processing of steps 5P35 to 5P3B is thus completed, the CPU 8 returns to the management database processing loop (FIG. 7) via steps 5P2B and 5P29.

Furthermore, when the user clicks on the "Management Data Reservation" item in the command standby state where the management data list is displayed, the CPU 8 enters the management data subroutine RT3, which forms part of the processing procedure shown in FIG. Management data reservation processing procedure R for switching reservation modes such as
Execute T31.

At this time, the CPU causes the user to select the timer reservation mode in step 5P41.

In this embodiment, as shown in FIG. 11, as a list of specified items that can be presented to the user for specifying and selecting specified items of management data, words consisting of word input items that express specified items using natural language. A designated item list TBL and a graphic designated item list consisting of graphic input items that represent designated items using graphic elements such as Roman letters, numbers, and symbols as usual are prepared, and in step 5P41, cpus The user is allowed to select and specify either word input or graphic manual input as the reservation screen to be used.

If the word input item is selected as a result, the CPU 8 moves to step 5P42, displays the word designation item list TBL on the display screen, and takes into the register 44 the data corresponding to the word input item specified by the user.

Conversely, if graphic input is selected, the CP
U8 moves to step 5P43, displays the graphic specified item list on the display screen, and stores data corresponding to the graphic manual item specified by the user in the register 44.
Incorporate into.

In this way, when the user's specified input operation is completed, the CPU 8
ends the management data reservation manual processing and returns to the management database processing loop shown in FIG.

At this time, the CPU then displays "Registration" item-1 "Change" item and "Inquiry" item on the display screen, and then performs step 5.
P51. In 5P52 and 5P53, the user
Clicking on the ``Register'' item, ``Change'' item, or ``Inquiry'' item starts the process of executing this.

Here, the CPU 8 processes the clicked item, and in steps 5P54, 5P55, and 5P56, it can display a calendar reservation table, a weekly reservation table, and a daily child schedule according to the user's selection, respectively, The start time and/or end time of the reserved program is written on the calendar reservation table, weekly reservation table, or daily child schedule.

After completing this process, the CPU 8 executes the above-mentioned step 5P2.
At step B, the processing program for the management database is ended, and the process returns to the management database processing loop (FIG. 7) from step 5P29.

The above is performed in step S in the initial command standby state shown in FIG.
By clicking on the "Management Database" item on P6, you can record, change, and record the management data on videotape.
This is a confirmation process, but if the user clicks on other specified items, such as the "system settings" item, the "favorite settings" item, or the "timer reservation" item in the initial command standby state, the CPU executes processing for setting the operating conditions of each part of the video tape recorder l.

That is, in step 5P61 of FIG.
When you click on ``System Settings,'' the display screen displays ``Current Time'' item, ``Sleep Timer'' item, ``Recording Mode'' item, ``Noise Elimination'' item, ``rBS Online'' item, ``Autoset'' item, and ``Tuner Preset'' item. ” item and “Line input” item are displayed, and these items can be selected in steps 5P62.5P63.5P64.5P6 respectively.
5. By clicking on SF36.5P67.5P6B or 5P69, you can set the operating conditions for each part of the system, and when you finish the setting process, click C.
The PU8 ends the processing of the system setting processing loop and moves to the above-mentioned step 5P1O.

On the other hand, when the CPU clicks on the "Favorite Settings" item in step SP71, the display screen displays the "Screen Display" item, "Management Database" item, "User Set" item, "Character" item, and "Timer Reservation" item. '' item, ``user level j item, ``message'' item, and ``audio'' item are displayed on the display screen, and these items are processed in steps SP72.5P73.5P74 and SF35, respectively.
゜5P76, SP? ? , 5P78 or 5P79, the CPU 8 executes the process for each item, and when the process is completed, the process moves to step 5PIO described above.

Furthermore, in the initial command standby state, when the user clicks on the first selection of timer reservations in the subsequent step SP81, the CPU 8 displays the "Register" item and the "Change" item on the display screen.
Display the item and "Inquiry" item, and the user can proceed to step 5P.
82. When each item is clicked on 5P83 or 5P84, "Calendar reservation table j item,""1 week reservation table" item, and "1 day child schedule" item are displayed on the display screen. Then, when the user specifies one of them, CP
U8 enters the calendar reservation table, one week reservation table, or one
By displaying the Japanese schedule, the user can make a reservation for a program using the reservation table.

When the CPU 8 has thus completed the processing of the timer reservation processing loop, it moves to the above-mentioned step 5pio.

In this way, by executing the input information processing program RTO shown in FIG. 7, the CPU can reliably control the video tape recorder main body 3 based on the input data input by the user.

(G5) Recording of recording end status information to program information block D□ When the recording control management data processing CPU finishes recording the program scheduled for recording, it executes the recording end status writing process as shown in Fig. 12. By doing so, recording end status information aDF indicating the recording end state of the program is stored as management data [)av in the program information block DPI in the management database audio track recording area Fava (or management database video track recording area Favv) of the video tape 36. The program information is written as DPIIK.

That is, when the video cassette 35 is attached to the video recorder body 3 and the management data mode command key 6F of the remote controller 6 (FIG. 10) is turned on, the control management data processing CPU 8 processes the management data. Step 5P90 to DavLfi output mode
(FIG. 12), the management data DAv of the management database video track recording area Favv or the management database audio track area FAV& formed on the video tape 36 in step 5P91 is converted to 1 by the magnetic conversion circuit 33 and the playback circuit 37. , the reproduction switching circuit 38, and the image recording decoder 52, and read into the register 44.

Next, cpus reads the current time written in item B9 of the management data Dav stored in the register 44.
When it is determined that the "recording start time" has arrived, the scheduled recording of the program is started, and in step 5P92, it is determined whether the current time has reached the "recording end time" written in the item BIO of the program information block DP11. determine whether
If a negative result is obtained, proceed to Step 5P92 while confirming that no abnormality has occurred in Step 5P93.
- In the loop of 3P93-3P92, recording of the reserved program is continued until the recording end time is reached.

During this time, for example, if an abnormality occurs in the power supply section of the videotape 36 or the videotape recorder 1, the control management data processing CPU 8, upon obtaining a positive result in step 5P93, moves to step 5P94 to detect the problem that occurred during recording. The cause of the abnormality (i.e. “Video tape 36
or "abnormality in the power supply section, etc." is written as "various flags" in item B3 of the management data I)av in the register 44, and then the process moves to step 5P95.

In step 5P95, the control management data processing CP
U8 determines whether the recording operation should be stopped immediately based on the degree of abnormality that occurred during recording of the program, and when it is determined that there is no abnormality that should be stopped, the process returns to step 5P92 described above and continues recording.

Eventually, in step 5P92, the CPU 8 determines that the current time has reached the recording end time, and then moves from step 5P92 to step 5P96 to control the mechanism control CPU II via the bus IO. After sending out the 11 signal S6 to stop the recording operation of the video tape recorder main body 3, it is determined whether or not abnormal contents have been written in the memory area of the register 44.

When it is confirmed that the recording has ended normally, the control management data processing CPU 8 moves to step 5P97, cues the beginning position of the video tape 36, and uses the management data Dav
Logic r00J (Fig. 14) indicating normal end of recording is written as "Recording end status JDy" in the first and second bits of item B3 indicating various flags (Fig. 13).

On the other hand, if it is determined that an abnormality has occurred during recording, the control management data processing CPU moves to step 5P98, cues the beginning position of the videotape 36, and sets it as the "recording end status JD" in the management data DAV. After writing the logical “10J data representing “tape abnormality” or the “01” data representing “power abnormality”, step 5P99
In this step, the recording process of the recording end status information ends.

On the other hand, when it is determined in step 5P95 that the recording operation should be stopped immediately during the recording operation, the control management data processing CPU 8 moves to step 5P96 and sends the control signal S6 to the mechanism control CPU 11 via the bus 10. After the video tape recorder body 3 stops the recording operation, the process moves to step SP9B, and if the abnormality that caused the recording operation to stop is a "tape abnormality", the logical "lO" data is sent. In addition, if there is a "power failure", write the logic "Ol" data and then proceed to step 5.
The process ends in P99.

According to the tank bottom described above, at the end of the recording operation, the management database recording areas F AVA and F AVV are configured to check whether the recording has ended normally or not, and if an abnormality occurs in the recording, the details of the abnormality are written. This allows you to check the recording status of the program without actually playing back and watching the videotape 36, and if an abnormality occurs during recording, you can check whether the cause of the abnormality was in the videotape 36 or not. By being able to determine whether the situation is warm or not, appropriate responses can be taken.
