Execute T31.

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

In this embodiment, as a list of specified items that can be presented to the user for specifying and selecting specified items of management data, as shown in FIG. An item list TBL and a graphic specified item list consisting of graphic input items representing specified items using graphic elements such as Roman letters, numbers, and symbols as usual are prepared, and the CPU 8 attempts to use them in step SP41. For the reservation screen, the user can select either verbal input or graphic input. If word input is selected as a result, the cpus moves to step SP42, displays the word designation item list TBL on the display screen, and takes into the register 32 the data corresponding to the word input item specified by the user.

Conversely, if graphic input is selected, the CP
U8 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 register 4.
Incorporate into 4.

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 database processing loop shown in FIG.

At this time, the CPU then displays the "Registration" item, the "Change" item, and the "Inquiry" item on the display screen, and then proceeds to step SP.
5 1, SP52 and SP53, the user
By clicking on the registration item j, the change item j, or the 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 reservation table in accordance with the user's selection in steps SP54, SP55, 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 reservation table. After completing this process, the CPU 8 executes the above-mentioned step SP2.
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 SP29.

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.

In other words, when you click on "User I) < r X7 Stem Settings" in step SP61 in FIG. ” item, “rBS Online” item, “Autoset” item, “Tuner Preset j item” and “Line Input” item are displayed, and these items can be set in steps SP62, SP63, and S, respectively.
By clicking on P64, SP65, SP66, SP67, SP6B or SP69, the operating conditions of each part of the system can be set, and when the setting processing is completed, the CPU 8 finishes the processing of the system setting processing loop. The process moves to step SPIO described above.

In response, the CPU 8 in step SP71
When you click on the ``Preferred Settings'' item, ``Preferences'' will appear on the display screen.
"Screen display" item, "Management database" item, "User set" item, "Character" item, "Timer reservation" item, "User level" item, "Message j item and [
Audio j items are displayed on the display screen, and these items are processed in steps SP72, SP73, SP74, and SP7, respectively.
5, SP7 6, SP7 7, SP7 B or SP7
When the button 9 is clicked, the CPU 8 executes the processing of each item, and when the processing is completed, the CPU 8 moves to the above-mentioned step SPIO.

Furthermore, in the initial command standby state, when the user clicks on the "timer reservation" item in the subsequent step SP81, the CPU 8 displays the "registration" item, "change item" and "inquiry" item on the display screen, and the user is step S
When you click on each item on P82, SP83 or SP84, the “Calendar Reservation List” item and “1
The "weekly reservation table" item and the "daily reservation table" item are displayed. Then, when the user specifies one of them, C
The PU8 displays a calendar reservation table, a weekly reservation table, or a daily reservation table in steps SP85, SP86, or SP87, respectively, and allows the program to be reserved using the reservation table.

When the CPU 8 thus completes the processing of the timer reservation processing loop, it moves to the above-mentioned step SPIO.

In this way, by executing the input information processing program RTO shown in FIG. 7, the CPU 8 can reliably control the video tape recorder main body 3 based on the input data input by the user.

(G5) Reservation based on word input items of management data As described above with respect to FIG. 8, the CPU 8 of the management data processing unit 5
executes management data reservation processing in the management data reservation subroutine RT3 in the command standby state in which the management data list is displayed on the display screen in step SP21.
Display the word specification item list TBL as shown in the figure,
Management data can be entered using the same method as if a human were speaking the verbal items. Furthermore, in addition to this, in the initial command standby state shown in FIG.
When executing the timer reservation in P8 1, the cpus similarly displays the word specification item list TBL shown in Fig. 11 on the display screens 4A and 6A, and inputs data using the word manual item. This allows users to easily and reliably input reservation items using the language they normally use.

In this embodiment, the word specification item list TBL is an arrangement of terms that allow the user to manually input command information to the video table recorder 1 in an interactive manner using natural language. Terms that express the operation content,
The operating time or terms representing the operating time are arranged so that they can be specified in units of one or more words.

In the case of this embodiment, the terms used to specify the time include terms that can specify the time before or after the current day or week, such as ``today,''``tomorrow,'' ``the day after tomorrow,'' and ``the day after tomorrow.''"Nextweek" is used, and "every week" and "daily J
is used, and terms that can specify the day according to the calendar are "month", "day", "Sunday" ~ [Saturday J], and 1
Terms that express the time of the day are ``am'', ``afternoon'', ``hour J'',
"r minutes" and "r minutes" are used.

Also, rBs is a term used to describe the input source to be recorded.
,,"line",[cable,1,rchJ,"β■"
is used.

In addition, the words "display" and "change" are used to command actions.
, "Cancel.", "V consecutive J", "Recording reservation", [End J
, ``Don't...'', and ``.'' are used.

In addition, the words [from], 1 to 1, wo, no, de, and ni are used to combine these terms, and rQ to 12 are used to input numerical information. "Yes" and "No" are used as man-machine dialogue terms with the CPU 8.

” is used.

In the case of this embodiment, the word specification item list TBL is CP
When the US executes the process for the "management data reservation" item in subroutine RT3 (Fig. 8), and in step S
When executing the process for the "timer reservation" item in P81 (FIG. 7), it is displayed on the display screen 6A of the remote controller 6 and the display screen 4A of the monitor 4, and thus the user can view the word specification item list TBL. By clicking on one of the terms arranged in , the command contents expressed by that term can be input to the CPU 8.

For example, if the user wants to make a new recording reservation for the first channel's program from 8:00 p.m. , ``no'', ``afternoon'', ``8'', ``hour,,''
[From,,,9,,,time,,"until,,"1yo,rch
l, ``Recording reservation'', ``.J items in that order.
Or you can click in any other order.

Here, when this operation is executed for the "management data reservation" item in subroutine RT3, the input data is once stored in the register 44, and then stored in the management database video track recording area F AVV of the video tape 36. or? In the recording area of the management data DAv of the management database audio track recording area F AVA, the recording start time information as the program information D FIX in item B9 of the program information block D■, that is, the data of [every Friday at 8:00 p.m.] is " At the same time, the program information D of item BIO, the information representing the recording end time, that is, the numerical data of "hours and minutes" representing "9 o'clock" is recorded as the program information D of item BIO, and furthermore, the numerical data of item B
Information representing the input source, that is, numerical data corresponding to "1 channel" is recorded as program information DP■ of No.7.

On the other hand, if the timer reservation changing process in step SP81 is executed, this data will be written to the reservation information memory provided in the video tape recorder main body 3 as new recording information.

Next, when changing the data that has been recorded up to now, for example, when "changing tomorrow's recording reservation for channel 6 to channel 8," the user lists the word specification items as a management data reservation process in subroutine RT3. Table T
Among the BL items, "tomorrow J,""no,""6," rch
”, “J,” “8”, “rch”, “to”, “change.” Operate the items in that order or in any other order.

In this way, the program information DPI of ring number B7 of the management database video track recording area F AVV of the video tape 136 or the management data DAV recording area of the management database audio track recording area F AVA
The input source information recorded as IK, i.e. r
6ch" is rewritten to the data of r8ch", thus making it possible to change the management data that has already been set. On the other hand, if the timer reservation changing process in step SP81 is executed, this data changes the recording information already written in the reservation information memory provided in the video tape recorder main body 3.

Next, if the user wants to "cancel the recording reservation for next Tuesday" among the already reserved programs, the user can use the subroutine R
At T3 or step SP8 1, among the items in the displayed word specification item list TBL, click the items "Next week", "Tuesday", "O", and "Cancel." in that order or in any other order. .

At this time, if the CPU 8 is executing the management data reservation of subroutine RT3, the CPU 8 selects the management data DAv recording area of the management database video track recording area FAVV of the video tape 36 or the management database audio track recording area FAVA. Item B9 Program information D Recording start time information recorded as FIK,
That is, it is possible to cancel all the reservation information for a program in which numerical data of "every Tuesday" is stored.

On the other hand, if the CPU 8 is executing the timer reservation in step SP81, the corresponding reservation information in the reservation memory provided in the video tape recorder main body 3 is canceled.

By making a recording reservation using the word specification item list TEL as shown in Figure 11, users can use the language they use in daily conversation as a means of inputting item data. Information can be input more easily and accurately.

(G6) Display of reservation data In the subroutine RT3 of FIG.
In a state where the word specification item list TBL as shown in FIG. 11 is displayed above, the user selects the "Display" item or the "Change" item.

” item or “Cancellation.” item, the CP
U8 executes the registration content display, change, or cancellation procedure RTII shown in FIG.

In other words, cpus first determines whether the process specified in step SP91 is a "display" item or a "change" item.
It is determined whether the item is an item or a "cancel" item, and when the "display" item is specified by the user, step SP9
Moving on to step 2, it is determined whether or not a selection item (also called selection item) has been specified.

Here, the selection items include items that can commonly specify multiple reserved programs or recorded programs (these are called registered programs), such as registered days such as "month", "r day", and "day of the week". Items that indicate the type of source of the registered program such as [Ch-1, ``Line'', ``Cable'', rBSJ], and items that indicate the type of source of the registered program such as ``What hour and minute'' and ``Until what hour and minute''. Items representing the start time and/or end time of the program are used.

If a negative result is obtained in step SP92, CP
U8 moves to step SP93 and displays a message prompting input on the display screen-H, for example, "When?", and then waits for a response input operation from the user in step SP94.

When a response input operation is performed, the CPU 8 passes through step SP92 and proceeds to step SP95 to confirm whether or not a time has been specified.

When the time is specified, the CPU 8 executes step SP9.
After proceeding to step SP97, a search is executed for the specified time range using the conjunction condition of the selected items, and then proceeding to step SP97.
On the other hand, if it is determined in step SP95 that no time has been specified, the step SP9B searches for registered information that satisfies the logical product condition of the selected items for all time ranges, and then moves to the above-mentioned step SP97.

In step SP97, the CPU 8 determines whether or not a program matching the specified content has been found as a result of the search.
When found, the found reserved program is displayed graphically on the remote controller 6 and the display screens 6A and 4A of the monitor 4, ie, as a selection item list HYO as shown in FIG. 13 in step SP99. On the other hand, if it cannot be found in step SP67, the CPU 8 moves to step SPIOO and displays a message to that effect, for example, "No reservation" on the display screens 6A and 4A.

In this embodiment, the graphic display in step SP99 is such that a plurality of registered programs can be displayed simultaneously, so that the user can read the registration status of the programs at a glance.

When the processing of step SP99 or SPIOO is finished, C
PtJ8 waits for the user to click the "end J item" in step SPIOI, and then executes step S
Management data reservation subroutine RT from P102 to FIG.
Return to the processing loop of step 3.

Next, in step SP9 1, the user changes 1. When it is detected that you have clicked J or "Cancel", CP
U8 moves to step SP103 to determine whether or not a selection item has been specified, and if no selection item has been specified, it displays "When?" in step SP104, and then inputs the user's designation in step SPI05. Waits for an operation, and when the user performs a specified operation, step SP1
03, and in step SP106, it is determined whether or not a time has been specified.

If the user confirms that the time has been specified here, the CP
U8 searches for registered information that satisfies the logical product condition of the selected items only within the time range specified in step SP107.

Next, the CPU 8 determines whether a program matching the specified content has been found in step SP10B, and when found, changes the found reserved program in step SP109, performs cancellation processing, and then executes the steps SPIOI and SP102 described above. After that, the process returns to the processing loop of the management data reservation subroutine RT3 shown in FIG.

In this embodiment, the change or cancellation process in step SP109 is executed one registered program at a time,
This prevents the reservation information from being accidentally lost all at once. On the other hand, if a negative result is obtained in step SP10B, the CPU 8 moves to step SPIIO and displays the specified registration information on the display screens 6A and 4A. After displaying a message indicating that the program was not found, for example "Not Found", the process returns to the processing loop of the management data reservation subroutine RT3 in FIG. 8 via steps SPIOI and SP102.

The above is the process when the time is specified, but if the user does not specify the time, the CPU 8 confirms this in step SP106 and executes the process in step SPII.
Shifting to step I, a registered program is searched using the selected items as logical product conditions, and in the following step SPl12, it is determined whether or not the reserved program is desired to be viewed, and when it is found, step S
P! ! In step SP109, it is confirmed whether or not there is a plurality of registered programs found, and if there is not a plurality of programs, the process immediately moves to step SP109 described above to execute a process of changing or canceling the found registered program.

When there are multiple registered programs found for this, C
The PU 8 moves to step SP114 and displays a message prompting selection based on the time of one of the plurality of reserved programs on the display screens 6A and 4A, for example, "What time does it start?", and then proceeds to step SP114. It waits for the time to be specified at SP115.

When it is confirmed in step SP115 that the user has specified the time, the CPU 8 proceeds to step S115.
Proceeding to P107, the process of re-searching for a registered program that satisfies the logical product condition of the selected items for the specified time range is executed. Further, when a negative result is obtained in step SP82, the CPU 8 displays a message "Not Found" on the display screens 6A and 4A in step SP116, and moves to step SPIOI.

At step SP96 in FIG. 12, registered programs that satisfy, for example, the conditions shown in FIG. 14 as the conjunction conditions of the selection items for the specified time range are searched and displayed.

In other words, for example, the specified time is [8:00 to 9:00].
When specifying the condition as a selection item, the recording start time f and recording that satisfy the conditions of this selection item are selected for the recording start time F and recording end time T of the registered programs PRCI-PRGIO in FIG. The registered program with end time t is
First, programs such as PRCI, PRG2, PR03, and PRG4 in Figure 14 satisfy the following conditions: F≦f and L≦T (1); Like the program PRG5 in Figure 14, it is a program that satisfies the following conditions: F≧f, t<T, and F<L (2), and thirdly, the number &llPR06 in Figure 14 is a program that satisfies the following conditions: As shown in FIG. The program satisfies the following conditions: f and L≧T (4). For this, in the same way, specify J as the selection item from 8:00 to 9:00 as the specified time, change ``From 8:00'' to ``8:30'', and change ``9:00'' to ``9:00''. 30 minutes", the registered program PRGI in Figure 15
1-PRG2 Among 1, the registered programs that satisfy the conditions of this selection item are first like programs PRG13 and PRG14, F=f or t=T ・Old...
(5), and secondly, the program PRGI
9, F=1 and t=T.Old...This is a program that satisfies (6).

According to the configuration shown in FIG. 12, by specifying selection items as necessary for a large number of registered programs that have already been reserved or recorded, the user selects only the reserved programs that have the specified selection items in step SP99. Display screen 6
A and 4A can be displayed graphically, thus allowing the user to see the most i1! Only the reserved programs or recorded programs that the user wishes to check can be displayed, for example, as a graphic in the form of a list, thereby making it easier to check the display of registered programs.

As a graphic display, as shown in FIG. 13, for example, a graphic display consisting of a list H YO in which the registration information of a plurality of registered programs, for example, four, is configured as a graphic display element of one line for each program is performed. can be applied.

In the case of Fig. 13, the selection items are "Monday", [9:00 PM to 9:57 PM], r 8 C H J,
By specifying these selection items, the user can, for example, check at a glance the registration status of a series program (i.e., whether it has been recorded, whether it has been reserved, and other conditions attached to each program). be able to.

Incidentally, in the case of this embodiment, in addition to information about the time to be reserved or recorded and the video source, the display column for each registered program also displays the content of the management data in a picture as shown in the rightmost part of FIG. The information is displayed using display elements, thereby making it easier for the user to grasp information about reservations and recorded programs.

In the above embodiment, a case has been described in which registered data is displayed item by item as a configuration when the CPU executes the process of the management database processing routine RTI (Figures 7 and 8), but this operation is performed in steps. In SP81 (FIG. 7), the user
It is executed in the same way when making a direct timer reservation (that is, when not using management data reservation). (G7) Other Embodiments (1) In the above embodiment, when outputting the management data I) Av, the management database video track recording area F Avv and the management database audio track recording area F AVA of the video tape 36 are Although we have described the case where data is recorded in both, the same effect as in the above case can be obtained even if data is recorded in only one of them. ? 2) In the above embodiment,
When inputting recording information from the remote controller 6, a word specification item list TB as shown in FIG.
L is used, but instead of this, other languages,
Even if a finger item list consisting of symbols etc. is used, the same effect as in the above case can be obtained.

(3) In the above embodiment, the case where the present invention is applied to a video tape recorder has been described, but instead of this, the above case can also be applied to a case where an audio signal is reserved for recording, such as in a so-called radio cassette player. Therefore, the present invention can be applied.

(4) In the above-mentioned embodiment, the volume information block D■ and the program information block D0 are written in that order from the head position of the recording track as the configuration of the management data I) av. Various changes may be made, such as changing the arrangement order or, depending on the case, dividing them into smaller pieces and mixing them.

H Effects of the Invention As described above, according to the present invention, the user can specify desired items when displaying registered data, so that the user can select only the programs he or she wants to check from a large amount of registered information. By being able to display items, it is possible to realize a program reservation device that can further simplify confirmation of registered information.
