After the CPU 8 rewrites the data of the "password" item to the "title" item in steps SP23 to SP27 in this way, when the "end" item is designated in step SP28, the CPU 8 ends the processing of the management database and proceeds to step 29. Then, the process returns to the management database processing loop shown in FIG. 7 to enter the processing of step SP8.

On the other hand, if the user clicks the "cancel reservation" item in the command standby state in which the management data list is displayed in step SP21 of FIG. 8, the CPU 8 proceeds to step SP21.
In SP30, all program reservations recorded in the management data list are canceled.

Also, when the user clicks on the "auto play" item,
CPU 8 switches to the program playback mode, and proceeds to step SP31.
The program is reproduced in the order determined by the reproduction order data of item A13 of the volume information D _VMX (FIG. 5).

When the user clicks on the "manual reservation" item, the CPU 8 sequentially accepts manual settings for a predetermined number of programs and inputs these as management data.

When the processing of steps SP30, SP31 and SP32 ends, the CP
U8 returns to the management database processing routine (FIG. 7) through the above-mentioned steps SP28 and SP29.

When the user clicks the "program information confirmation" item in the command standby state for displaying the management data list in step SP21 of FIG. 8, the CPU 8 enters the processing of step SP33 and displays the display screen in step SP34. Switch the display of step SP35 or SP36 or SP3
7, or SP38, the recorded contents of the "recording permitted" item, the "watch flag" item, the "category" item, and the "title" item of the volume information D _VMX (FIG. 5) and the program information D _PRX (FIG. 6) Becomes a display mode in which can be confirmed or rewritten.

In the case of this embodiment, a predetermined picture display, that is, a character is used as the data of the “recording permission” item, the “seen flag” item, the “category” item, and the “title” item, so that the display area is relatively small. Thus, information recorded on a plurality of reserved programs can be confirmed and changed.

When the processing of steps SP35 to SP38 is completed, the CP
U8 returns to the management database processing loop (FIG. 7) via steps SP28 and SP29.

Further, when the user clicks the "reservation of management data" item in the command standby state displaying the management data list, the CPU 8 enters the management data subroutine RT3 and forms a part of the processing procedure as shown in FIG. The management data reservation processing procedure RT31 for switching the reservation mode is executed.

At this time, the CPU 8 allows the user to select the timer reservation mode in step SP41.

In the case of this embodiment, as a specification item list that can be presented to let the user specify and select the command item of the management data,
As shown in FIG. 11, the designated item is represented by a word input item representing the designated item using a natural language, and the designated item is represented by using a graphic element such as a Roman character, a number, a symbol, etc. as usual. A list of graphic specification items consisting of graphic input items is prepared, and the CPU 8 executes the step.
In SP41, the user is caused to select and specify either a word input or a graphic input as a reservation screen to be used.

As a result, when the word input is selected, the CPU 8 executes the step.
The process proceeds to SP42, where the word designation item list TBL is displayed on the display screen, and the data corresponding to the word entry item designated by the user is loaded into the register 44.

Conversely, if graphic input is selected, CP
U8 proceeds to step SP43 to display a graphic specification item list on the display screen, and fetches data corresponding to the graphic input item specified and operated by the user into the register 44.

Thus, when the user's designation input operation is completed, the CPU 8 ends the management data reservation input processing and returns to the processing loop of the management database in FIG.

At this time, the CPU 8 subsequently displays a “register” item, a “change” item, and an “inquiry” item on the display screen, and proceeds to step SP51,
In SP52 and SP53, the user clicks on the "registration" item, "change" item, or "inquiry" item to enter a process of executing this.

Here, in processing the clicked item, the CPU 8 can display the calendar reservation table, the weekly reservation table, and the daily reservation table in steps SP54, SP55, and SP56, respectively, according to the user's selection. The start time and / or end time of the reserved program is written on a calendar reservation table, a one-week reservation table, or a one-day reservation table.

When such processing is completed, the CPU 8 terminates the processing program of the management database in the above-mentioned step SP28,
Step SP29 to the management database processing loop (7th
Return to figure).

The above steps are performed in the initial command standby state shown in FIG.
In SP6, the management data is recorded, changed, and confirmed on the videotape by clicking the "management database" item. In the initial command standby state, other specified items, that is, the "system setting" item Or, when the user clicks the item of “preference setting” or the item of “timer reservation”, the CPU 8 executes a process of setting operating conditions of each unit of the video tape recorder 1.

That is, when the user clicks "system setting" in step SP61 of FIG. 7, the "current time" item, the "sleep timer" item, and the "recording mode" are displayed on the display screen.
Item, "Noise Elimination" item, "BS Online" item,
"Auto set" item, "Preset" item and "Line input" item are displayed. Step SP62, SP63, SP64, SP65, SP66, SP67, SP
By clicking at 68 or SP69, the operating conditions of each part of the system can be set. When the setting processing is completed, the CPU 8 ends the system setting processing loop and proceeds to the above-mentioned step SP10.

On the other hand, when the CPU 8 clicks the "Preference setting" item in step SP71, the "screen display" item, "management database" item, "user set" item, "character" item, and "timer reservation" item are displayed on the display screen. "item,
The "user level" item, the "message" item and the "voice" item are displayed on the display screen, and these items are step SP72, SP73, SP74, SP75, SP76, SP77, SP, respectively.
When clicked at 78 or SP79, the CPU 8 executes the processing of each item, and when the processing is completed, proceeds to the above-mentioned step SP10.

Further, in the initial command standby state, when the user clicks the “timer reservation” item in the following step SP81, the CPU 8 displays the “registration” item, the “change” item, and the “inquiry” item on the display screen, and the user Step SP82, SP83
Alternatively, when each item is clicked in SP84, the “calendar reservation table” item, “one week reservation table” item, and “one day reservation table” item are displayed on the display screen. Subsequently, when the user specifies one of them, the CPU 8 executes steps SP85 and SP85.
At 86 or SP87, a calendar reservation table, a one-week reservation table, or a one-day reservation table is displayed, and the program is reserved using the reservation table.

When the CPU 8 finishes the processing of the timer reservation processing loop, it proceeds to the above-mentioned step SP10.

In this way, the CPU 8 stores the management data D _{AV in the} register 44.
There Once constructed, holds the management data D _AV, by "management database" item is clicked, recording management data D _AV in the management database video tiger poke recording region F _AVV.

This enables management data recorded for each video cassette
The video tape recorder main body 3 can be controlled based on the D _AV .

On the other hand, if the “management database” item is not clicked, the management data D _AV stored in the register 44 is
, The video tape recorder main body 3 can be controlled.

(G5) Late recording mode As described above with reference to FIG. 8, when the control management data processing CPU 8 executes the input processing procedure and sets the timer reservation, the information on the timer reservation (that is, items B7, B9,
Timer recording based on the information of B10 and B11).

That is, the video cassette 3 in which the management data D _AV is recorded
When 5 is loaded into the video tape recorder main body 3, the control management data processing CPU 8 enters the management database playback mode while communicating with the mechanism control CPU 11, and enters the management database video track recording area F of the video tape 36.
_The data video signal picked up from the _AVV is read out via the magnetic head 34, the video electromagnetic conversion circuit 33, the reproduction circuit 37, the reproduction switching circuit 38, and the image recording decoder 52, and is written into the register 44.

Thus, the management data D _AV (FIG. 4) is held in the register 44 as management data unique to the video tape 36, whereby the timer reservation information is stored in the register 44, and based on the timer reservation information. Timer recording.

If video cassette 35 is not loaded,
Alternatively, when a video cassette 35 in which no management data is recorded is loaded, steps SP81 to SP87 (the seventh
By executing the processing shown in FIG. 3, information on timer reservation is stored in the register 44, and timer recording is performed based on the timer reservation information.

At this time, the control management data processing CPU 8 executes the processing procedure shown in FIG. 12 when the video cassette is forgotten to be loaded in spite of the timer reservation, or when the timer reservation is canceled and recording is performed again. The mode switches to the late recording mode.

That is, the control management data processing CPU 8 executes step SP90.
From proceeds to step SP91, it is determined whether the recording start time based on the management data D _AV recording start time of the item B9.

Here, since a negative result is obtained before the recording start time, the control management data processing CPU 8 executes the step.
Repeat SP91.

On the other hand, when the recording start time arrives, a positive result is obtained in step SP91, so that the control management data processing CP
U8 moves to step SP92, and determines whether or not a video cassette is loaded.

That is, the user views the broadcast program directly despite the timer reservation, and does not load the video cassette because recording is not necessary in this case, or discharges the loaded video cassette, thereby making the timer reservation. To release.

Accordingly, in the control management data processing CPU 8, if a positive result is obtained in step SP92, the process proceeds to step SP93, where the input source of the item B7 reserved for the timer is recorded until the recording end time of the item B10, and thereafter, the process proceeds to step SP94. Then, the processing procedure ends.

Thus obtained was the timer reservation based on the timer reservation information stored in the timer reservation information or register 44 recorded on a video cassette, by using a video cassette which records management data D _AV optionally per video cassette You can record weekly series programs.

On the other hand, if a negative result is obtained in step SP92,
The control management data processing CPU 8 proceeds to step 95 and determines whether or not the late recording flag is set.

Here, the late recording flag is set by selectively clicking the “late recording possible” and “late recording impossible” items displayed on the display screen 6A when the user makes a timer reservation. When the "OK" item is clicked, a late recording flag is set up in the register 44 and stored.

With this, the control management data processing CPU 8 waits for the elapse of the recording start time when the late recording flag is on, and on the condition that timer recording cannot be performed because no video cassette is loaded, Stand up to mode.

That is, the control management data processing CPU 8 executes step SP95
If a negative result is obtained in step SP96,
After displaying the message of "this reservation will be canceled" on the display screen 6A, the process moves to step SP94 and ends the processing procedure.

On the other hand, if a positive result is obtained in step SP95, the flow shifts to step SP97 to execute the processing procedure of the late recording mode.

That is, the control management data processing CPU 8 executes step SP97.
In the display screen 6A, "After setting the video cassette,
After the message "Start recording" is displayed, the flow shifts to step SP98 to determine whether or not the video cassette is loaded.

Here, if the video cassette is not loaded, a negative result is obtained, and the control management data processing CPU 8 proceeds to step SP99.
Then, it is determined whether the recording end time of the item B10 has been reached.

Here, since a negative result is obtained before the recording end time, the control management data processing CPU 8 proceeds to step SP.
On the other hand, when the recording end time is reached, a positive result is obtained, and the process proceeds to step SP100, where the message "Time for recording has ended" is displayed, and then the process proceeds to step 94. The processing procedure ends.

Thereby, in the control management data processing CPU 8, in the late recording mode, while the recording time is left,
It is made to wait for loading of the video cassette.

On the other hand, when the video cassette is loaded, a positive result is obtained in step SP98, and the control management data processing CPU 8 proceeds to step SP101, where the message "Please confirm the recording start position" is displayed. Is displayed.

That is, the user may notice that the video cassette is not loaded even though the timer has been reserved, and then load the ready-made video cassette quickly.

In this case, in the loaded video cassette, there is a case where a measure for preventing erroneous erasure is not taken and a valuable program which is not desired to be erased is recorded.

Accordingly, in the control management data processing CPU 8, after displaying the message, the process proceeds to step SP 102, and if necessary, the user jumps to the head, and then clicks the item of “confirmation” (displayed with the message). By judging whether or not the video cassette is incorrectly recorded, the video cassette is prevented from being recorded.

Thus, the control management data processing CPU 8 determines whether or not the recording start position has been confirmed in step SP102.
Here, if a negative result is obtained, the process returns to step SP101, whereas if a positive result is obtained, the process proceeds to step SP103.

Here, the control management data processing CPU 8 determines whether or not the recording end time of the item B10 has come.

Here, a negative result is obtained before the recording end time, so that the control management data processing CPU 8 executes the step.
After moving to SP104 and recording the input source of the item B7 reserved by the timer until the recording end time of the item B10, the process proceeds to step SP94.
And ends the processing procedure.

Thus, at the time of timer reservation, after clicking on the item of "late recording", the video cassette is stored in the timer reservation information or the register 44 by a simple operation of only loading the video cassette as necessary. Based on the timer reservation information, the remaining portion of the program that has already started broadcasting can be recorded, and the usability of the video tape recorder 1 can be improved accordingly.

On the other hand, when the recording end time comes, an affirmative result is obtained in step SP103, and the control management data processing CPU 8 proceeds to step SP105, where a message "Time has passed" is displayed, and then step SP94 is executed.
And ends the processing procedure.

According to the above configuration, in the late recording mode, by starting recording even after the elapse of the recording start time based on the information of the released timer reservation, it is possible to record the program whose timer reservation has been released by a simple operation, Accordingly, the usability of the video tape recorder 1 can be improved.
