B. Summary of the Invention The present invention enables an information recording/reproducing apparatus to easily control external devices by assigning and storing external device control data to management data corresponding to each program.

C. Prior Art Conventional consumer video tape recorders use an internal tuner and timer to transmit reservation information for each program to the user when recording multiple programs on a videotape that extends in the horizontal direction. The recording is performed by setting reservations one by one.

When playing multiple programs recorded in this way,
For example, a cue signal is recorded at the beginning of each program in advance, and the user sets the video tape recorder to search mode, fast-forwards the videotape to a position where the cue signal can be played, and then switches to playback mode. The user switches the program to check whether it is the program they want to watch or not.

Problems to be Solved by the Invention As described above, conventional video tape recorders are capable of performing only relatively simple functions, and therefore, when in the scheduled recording mode, during a desired time period, for example, a tuner, a video tape recorder, etc. One or more video tapes installed as external devices can record video in conjunction with external devices such as tape recorders and other various video sources, and can be set up as external devices at predetermined timings as needed during playback mode. It was not possible to perform detailed control of external equipment, such as dubbing the reproduced video signal to the recorder or displaying it on the monitor.

The present invention has been made in consideration of the above points, and aims to further facilitate systemization with external devices by making it possible to send control signals to external devices in a wide variety of ways as required. The purpose of this paper is to propose an information recording and reproducing device that uses the following methods.

The reproduction order data of item A13 of NX (FIG. 5) is reproduced in a fixed order and rewritten as necessary.

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

When the processing of steps 5P30.5P31 and 5P32 is completed, the CPU 8 executes the steps 5P28.5P29 described above.
and returns to the management database processing loop (FIG. 7).

Further, when the CPU 8 is in the waiting state for a command to display the 1ζ management data list in step 5P21 of FIG.
8 enters the process of step 5P33 and goes to step 5P34
Switch the display on the display screen and proceed to step 5P3.
5, or 5P36, SP37, or 5P38, the volume information DVMX (Figure 5) and program information DP ” The display mode becomes such that the recorded contents of the item 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 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 5P38 is thus completed, the CPU 8 returns to the management database processing loop (FIG. 7) via steps 5P28 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

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 the CPU 8, in step 5P41, The user is allowed to select and specify either verbal input or graphic input as the reservation screen to be used.

As a result, if the verbal skill is selected, 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 verbal skill item specified by the user.

On the other hand, if graphic human power is selected, 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 input process and returns to the management database processing loop shown in FIG.

At this time, the CPU 8 subsequently displays the "registration" item, "change" item, and "inquiry" item on the display screen, and in step 5P
51, 5P52 and S P 534:: 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 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 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 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, "Recording mode j item, "Noise cancellation" item, rBS online" item, "Auto set" 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.
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.

In response, in step 5P71, the CPU 8 says, ``When you click on the desired setting j item, the display screen displays ``Screen display j item,'' ``Management database'' item, ``User set'' item, ``Character'' item, and ``Timer reservation.'''' item, ``User Level'' item, ``Message'' item, and ``Audio'' item are displayed on the display screen, and these items are each displayed in step SP? 2.5P73.5P74.5P75
, SF76.5P77.5P7B, or 5P79, the cpus executes the processing of each item, and when the processing is completed, it 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 selects the "Register" item and the "Change" item in the display screen improvement.
Display the item and "Inquiry" item, and the user can proceed to step 5P.
82.5 When each item is clicked on P83 or SF34, the items ``Calendar Reservation Table'', ``1 Week Reservation Table'', and ``1 Day Child Schedule'' are displayed on the display screen. Then, when the user specifies one of them, C
The PU8 displays a calendar reservation table, a one-week reservation table, or a one-day child reservation table in steps 5P85, 5P86, or sp87, respectively, and allows the program to be reserved 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 5 PIO.

In this way, by executing the input information processing program RTO shown in FIG. 7, the CP and U8 can reliably control the video tape recorder main body 3 based on the manual data input by the user.

(G5) External device control processing In step 5P32 shown in FIG. 8, the control management data processing CPU 8 inputs "scheduled recording control information" manually by the user into item B of the management data [)av.
