The display mode becomes such that the recorded contents of the ``recording permission'' item, ``viewed flag'' item, ``category'' item, and ``title j'' item of X (Figure 6) can be confirmed or rewritten.

In this example, "recording permission" item, "saw flag"
A predetermined pictorial display, that is, a character, is used as the data for the "Category j item" and "Title j 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 CPL 18 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 8 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 the CPU 8, in step SP41, The user is allowed to select and specify either verbal input or graphic input as the reservation screen to be used.

If word input is selected as a result, the CPU 8 moves to step SP42, 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
In step 5P43, tJ8 displays a graphic designation item list on the display screen, and data corresponding to the graphic input item specified by the user is loaded into the register 44.

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

At this time, the CPU 8 subsequently displays the "Registration" item, the "Change j item" and the "Inquiry j item" on one display screen, and then proceeds to step S.
P51. In 5P52 and 5P53, the user
Clicking on the ``registration'' item, the ``change J item,'' or the ``inquiry'' item starts the process of executing this.

Here, when CPtJ8 processes the clicked item, it is made possible to display a calendar reservation table, a weekly reservation table, and a daily child schedule according to the user's selection in steps 5P54, 5P55, and SP56, respectively. The start time and/or end time of a 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.
In step 8, the processing program for the management database is terminated, 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 any other specified item, that is, the "system settings" item, the "favorite settings" item, or the "timer reservation" item in the initial command standby state, the CPU 8 executes processing for setting operating conditions for each part of the video tape recorder 1.

That is, in step SP61 of FIG.
When you click "System Settings," the display screen displays the "Current time" item, "Sleep timer item,""Recordingmode" item, "Noise cancellation" item, rBS Online item, "Auto set" item, and "Tuner preset" item. 1j item and "Line input" item are displayed, and these items are respectively entered in step 5P62.5P63.5P64.5P6
By clicking on 5.5P66.5P67.5P68 or 5P69, you can set the operating conditions for each part of the system, and when the setting process is finished, C
The PU 8 ends the processing of the system setting processing loop and moves to the above-mentioned step 5 PIO.

In contrast, when the CPU 8 clicks on the "favorite settings" item in step SP71, the display screen displays the "screen display" item, "management database j item,""userset" item, "character" item, and "timer reservation" item. '' item, ``user level'' item, ``message j item,'' and ``audio'' item are displayed on the display screen, and these items are processed in steps SP72.5P73, SF34, and SF35, respectively.
When clicked on ゜5P76, SF37.5P7B or SF39, the CPU 8 executes processing for each item, and when the processing is completed, the process moves to step 5PIO described above.

Furthermore, in the initial command standby state, when the user clicks on the "timer reservation" item in the subsequent step 5P81, the CPU 8 displays the "registration" item and the "change" item on the display screen.
Display the item and "Inquiry" item, and the user can proceed to step 5P.
82.5 When you click on each item on P83 or ζP84, the "Calendar reservation table" item, "1 week reservation table" item, and "1 day child schedule j item are displayed on the display screen. Next, Part 1 If the user specifies one, cp
us is the calendar reservation table, 1 week reservation table, or 1 in step 5P85.5P86 or 5p87, respectively.
By displaying the Japanese schedule, the user can make a reservation for a program using the reservation table.

In this way, when the management data is constructed in the register 44, the CPU 8 holds the management data and
When management database j item is clicked,
Management data is recorded in the management database video track recording area FAVV.

Thereby, the video tape recorder main body 3 can be controlled based on the management data recorded for each video cassette.

On the other hand, if the "Management data base" item is not clicked, the video tape recorder main body 3 can be controlled based on the management data stored in the register 44.

(G5) Abnormality display mode As described above with reference to FIG.
Timer recording is performed based on B9, BIO, and B11 (consisting of information 7).

That is, when the video cassette 35 on which management data is recorded is loaded into the video tape recorder main body 3, the control management data processing CPU 8 is activated by the mechanism control CPU II.
The data video signal picked up from the management database video track recording area FAVV of the video tape 36 is transferred to the magnetic head 34, the video 1 is transferred to the magnetic conversion circuit 33, the playback circuit 37, and the playback switching circuit 38. , and is read out via the image recording decoder 52 and written into the register 44.

Thus, the register 44 contains the management data DAv (FIG. 4).
is held as unique management data on the videotape 36, thereby allowing timer recording to be performed based on the timer reservation information stored in the register 44.

On the other hand, if the video cassette 35 is not loaded,
Or a video cassette 35 on which no management data is recorded.
If it is loaded, step 5P81 to step 5P
87 (FIG. 7), timer reservation information is stored in the register 44, and timer recording is performed based on the timer reservation information.

At this time, in the control management data processing CPU 5, if the user forgets to load the video cassette even though the timer has been reserved, or if the recording time of the video cassette is insufficient, it switches to an abnormality display mode and alerts the user. do.

That is, when the recording start time comes in the timer reserved state, the control management data processing CPU 8 (control management data DAv
(determined based on item B9), the control information S6 is sent to the mechanism control CPUI 1, and timer recording is started.

At this time, via the bus 10, the CPU II for mechanism control
When error information indicating that the tape cassette is not loaded is transmitted from the CPU 8, the control management data processing CPU 8 switches to an abnormality display mode and causes the display device 60 to flash.

Here, the display device 60 is composed of a high-intensity red light emitting diode placed on the operation panel, and thereby indicates to the user that there is some abnormality.

Similarly, the control management data processing CPU 8 switches to the abnormality display mode if tape end error information is output from the mechanical control CPU I before the recording end time (consisting of item BIO) after starting timer recording. Instead,
The display device 60 blinks.

Further, when the control management data processing CPU 8 becomes unable to record during timer recording due to a power outage, for example, after the power outage is restored, the control management data processing CPU 8 switches to an abnormality display mode and displays a blinking display on the display device 60.

Furthermore, the control management data processing CPU 8 is connected to a display device 60.
At the same time, it outputs abnormality detection information indicating the contents of the abnormality to the video display processor 41, and thereby uses a character generation circuit built in the video display processor 41 to display a message indicating the contents of the abnormality. Bottom out.

As a result, a message indicating the content of the abnormality is outputted to the monitor device 4 by sequentially controlling the superimpose fader circuit 24, the output selection circuit 39, and the video processing circuit 40.

Therefore, the user can recognize that some kind of abnormality has occurred by the blinking of the display device 60, and can understand the nature of the abnormality by turning on the power switch 4B of the monitor device 4.

Therefore, by loading or replacing the tape cassette as necessary, timer recording can be performed without missing valuable recording opportunities, and the video tape recorder 1 can perform timer recording without missing valuable recording opportunities.
Usability can be improved.

Furthermore, in the abnormality display mode, when the user operates the key pose 12 to cancel the abnormality display mode, the control management data processing CPU stops the flashing display of the display device 60 and the message output, and then returns to the normal operating state. to return to.

At this time, when the user turns on the "management database" item, the control management data processing CPU 8 records the content of the abnormality in the management database video track recording area FAvV together with the management data DAV.

As a result, in the control management data processing CPU 8,
For each timer-recorded tape cassette, it is possible to check the details of the abnormality during recording, and in this embodiment, when the tape cassette is played back, the abnormality recorded in the management database video track recording area F Avv can be checked as necessary. You can check the contents.

According to the above configuration, when an abnormality is detected during timer recording, the display word W60 is displayed blinking and a message indicating the content of the abnormality is output to the monitor device 4, so that the message is displayed via the blinking display on the display device 60. The details of the abnormality can be communicated to the user who turned on the monitor device 4 by calling the user's attention.
