, or 5P36, 5P37, or 5P3B, the volume information DvM (Figure 5) and the program information DPI
The display mode becomes such that the recorded contents of the "recording permission" item, "seen flag j" item, "category" item, and "title" item of X (Figure 6) can be confirmed 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 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, the specified items are expressed 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 cpus, in step SP41, The user selects and specifies 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.

On the other hand, if graphic human power is selected, cp
us moves to step SP43, displays a graphic designation item list on the display screen, and stores data corresponding to the graphic input 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 8 subsequently displays the "registration" item, the "first change" item, and the "inquiry" item on the display screen, and in step 5P
51. In 5P52 and 5P53, when the user clicks on the "Registration" item, "Change" item, or "Inquiry" item, the process to execute this starts.

In order to process the clicked item, the CPU 8 is configured 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 5P56, 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 this process is completed, the CPU performs step 5P2 described above.
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 in P'6, the management data is recorded on video tape, changed, and confirmed.In the initial command standby state, other specified items, that is, "System Settings" are processed. item,

That is, in step SP61 of FIG.
When you click on "System Settings", the display screen displays the "Current time" item, "Sleep timer item", "Recording mode" item, "Noise cancellation" item, "rBS online" item, "Auto set" item, and "Tuner preset" item. ” item and “Line input 1st line” will be displayed, and these items will be displayed in step SP62.5P63.5P64.5P6 respectively.
By clicking on 5.5P66.5P67.5P6B or 5P69, you can set the operating conditions for each part of the system, and when the setting process is finished, click C.
The PU 8 ends the processing of the system setting processing loop and moves to the above-mentioned step 5 PIO.

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 Datum - Top 31,""UserSet" item, "Character" item, ""Timerreservation" item, "User health j item,"Message" item, and "Voice j item" are displayed on the display screen, and these items are processed in steps 5P72, 5P73, SP74, and SP75, respectively.
゜When clicked on 5P76, SP77, SP7 B or 5P79, the CPU 8 executes the process for each item, and when the process is finished, the CPU 8 executes the process in step 5PIO described above.
Move to.

Furthermore, in the initial command standby state, when the user clicks on the first timer reservation in step SP81, the CPU 8 displays the "Register" item and the "Change" item on the display screen.
Display the item and the 1st page of the inquiry, and the user selects step 5P.
82. When each item is clicked on 5P83 or 5P84, the "Calendar Reservation Table" item, the "1 Week Reservation Table" item, and the "1 Day Child Schedule" item are displayed on the display screen. Then, when the user specifies one of them, CP
U8 is the calendar reservation table, la interval reservation table, or 1 in steps 5P85, 5P86 or 5P87, respectively.
By displaying the Japanese schedule, the user can make a reservation for a program using the reservation table.

When the CPU thus completes the processing of the timer reservation processing loop, it moves to the above-mentioned step 5 PIO.

In this way, the CPU 8 can reliably control the video tape recorder main body 3 based on the input data input by the user by executing the human information processing program RTO shown in FIG.

(G5) Recorded Content “Have You Seen?” Confirmation Process Operation After the user has played back a predetermined recorded program and enjoyed the content, the user uses the remote controller 6 or the keyboard 12 to check the program information DP, 1X corresponding to the recorded program. The "seen flag information" provided for the various flags in item B3 is rewritten to an on state (that is, "1").

Therefore, for recording-based programs that the user has played at least once in the past, the "saw flag information" corresponding to the program is rewritten to the on state, so that the C.
By detecting this "seen flag information J," the PU 8 is able to provide the user with information as to whether each recording method program has been played back in the past.

That is, the "saw flag information" i recognition processing procedure RT51 shown in FIG. 12 shows the "saw flag information" confirmation processing operation in the input information processing and management database setting processing shown in FIGS. 7 and 8. , step S in FIG.
The management data DAv (FIG. 4) recorded in the management database video track recording area FAVV or the management database audio track recording area FAvA of the video tape 36 loaded in step P7 is transferred to step 5P1.
After reading it in step 21, it is temporarily stored in the register 44 (FIG. 1), and in the following step 5P122, it is read in the
By executing the processing operation of step 5P36 shown in the figure, program information DPIX (6th
It is determined whether the 4th bit "seen flag information" of the "various flags" recorded as item B3 in FIG.

If a negative result is obtained here, this means that the recorded program corresponding to the "seen flag information J" has never been played back, and the CPU 8 returns to step 5.
Jumping to P123, in step 5P124, among the graphic displays HYO as shown in FIG. 13 displayed on display screens 4A and 6A, a pictorial display E Y E CL with closed eyes is displayed on the right end portion for the currently read program. indicate.

If a positive result is obtained, this means that the currently read recorded program has been played back in the past, and the CPU 8 moves to step 5P123 to display the video tape recorder installed on the video tape recorder body 3 side. "Did you see it"
The internal flag is turned on (that is, it is controlled to the "watched" state), and in the following step 5P124, a pictorial display with open eyes EYE is displayed in the display column of the program.

Therefore, the user can select the pictorial display EYEC that is displayed based on the "seen flag information" for the recording method program among the display columns of each registered program displayed on the graphic display HYO.
By checking L or E Y E op, it is possible to check whether the program in question has been played back and watched even once in the past. is the eighth in step 5PI25.
By moving on to the process of step 5P28 shown in the figure, the processing operation is ended.

Therefore, for example, in FIG. 12, the first registered program and the second
If the registered program is already registered under the recording method and the user has watched the recorded content of the first recording method registered program in the past (
In other words, if the recorded program has been played in the past)
, a pictorial display with open eyes in the first registered program display column E Y
By displaying the E OP, the user can confirm that he or she has seen it in the past without having to go through the trouble of playing it back and confirming its contents.

In addition, if the user has not seen the recorded content of the second recording method registered program in the past (that is, if the recorded program has not been played in the past), the user closes his or her eyes in the second registered program display field. By displaying the pictorial display EYEcL, the user can confirm that he has not yet watched the second recording method registered program.

Thus, by simply loading the videotape 36 into the videotape recorder main body 3, the user can check whether or not the user has viewed the content recorded on the videotape 36 in the past on the display screen 4A of the monitor 4 and through the remote control. This can be confirmed on the display screen 6A of the device 6.
