C. Prior Art Conventional video tape recorders as consumer information recording and reproducing devices record a cue signal at the beginning of each program when recording a plurality of programs on a longitudinally extending videotape. For example, if a user wants to play back a desired program from a recorded tape, the user first sets the video tape recorder to search mode, fast-forwards the video tape to a position where the cue signal can be played, and then - The user switches to the playback mode and checks whether the program is the one he or she wants to watch.

D Problems to be solved by the invention However, in this conventional video tape recorder,
Information about multiple programs is recorded for each program only at the videotape location where each program is recorded. Therefore, the user can check the program he or she wants to play, or decide which program he or she wants to play. When searching for a program to play, the user must repeatedly search the video tape recorder to find the program he or she wants to play, which actually involves fast-forwarding the video tape for quite a long time. There is an unavoidable complexity.

In addition, when managing a large number of recorded or unrecorded video tapes, or when managing so-called series programs recorded across multiple video tapes, it is practical to record each video tape separately. The contents of the program,
There is a complication in that the user has to perform management work such as writing management information such as the recording time and whether or not it is necessary to save on the video tape cassette or cassette case in advance.

However, in practice, the time and effort required to write this management information and to read and judge the written management information are complicated, and the degree of complexity depends on the number of programs and video tapes to be recorded or reserved. The more the value increases, the more it is cumulatively weighted, so it is desirable to simplify it as much as possible.

The present invention has been made in consideration of the above points, and is designed to further simplify the processing of recording and reservation information when recording and reserving programs (this is called recording and reservation). The purpose of this paper is to propose an information recording and reproducing device that uses the following methods.

Means for Solving Ellll In order to solve this problem, in the present invention, the recording tracks TA, TB and CHI formed on the recording medium 36 are
, CH2, the information recording/reproducing device 1 is configured to record one or more programs on the recording track TA,
Management database recording areas F AVA and F avv are formed at predetermined positions of TB, CHI, and CH2, and management data DAI+ for the program is recorded in the management database recording areas F AVA and F avv, and is recorded as management data D□. Finished flag F■. By writing this, recording reservation information corresponding to the program is diverted to recorded information.

1 Effect management database recording area F' ay and F MII
By recording the recorded flag Fzzc as management data D in the IF, program information written as reservation information can be used as recorded program information, and processing of recording and reservation information can be further simplified.

(G4) Video tape recorder setting processing
The video signal processing section 2 and the video tape recorder main body 3 are processed by a processing program RTO1 shown in FIGS. 7, 8, and 9.
By processing according to RT1 and RT31, the operating state is controlled to be the one specified by the user.

In the case of this embodiment, the remote controller 6 has a display screen 6A having a touch panel on a liquid crystal panel on the operation panel on the surface of the case, as shown in FIG.
When designated items are displayed as a list on the display screen 6A, a designated signal regarding the displayed item can be input by directly pressing and clicking each displayed item. In addition, after specifying a predetermined display item by moving the cursor displayed on the display screen 6A using the four-way cursor keys 6B, a specification signal regarding the display item is input by operating the execution key 60. It is made to be obtained.

Furthermore, the remote controller 6 has a normal operation command key 6D, a menu display command key 6E, a management data mode command key 6F, and reservation 1 and reservation 2 operation mode designation keys 6G and 6H. In contrast, the operation mode of the video tape recorder l can be specified.

Step SP of the input information processing program RTO in FIG.
In I, the CPU 8 waits for the power to be turned on, and when a positive result is obtained, it is determined in step SP2 whether or not the power is turned on for the first time, and if it is the first time, steps SP3, SF3 and By sequentially executing the processing of SF3, the message "Setting the time" is displayed on the display screen 4A of the monitor 4 and the display screen 6A of the remote controller 6, and then the current time is set using the system setting operation mode. A message "Time has been set" is displayed on display screens 4A and 6A.

In this way, the video tape recorder I enters the standby state for commands that set the current time.

This command standby state is maintained even when a negative result is obtained in step SP2, and thus the "management database", "system settings", "favorite settings" and "timer reservation" items are maintained in the command standby state. You can now perform selective operations.

In fact, in this command standby state, when the menu display mode designation key 6E is operated on the remote control controller 6 (or keyboard 12), the CPU 8 displays "management database", "system settings", etc. on the display screens 6A and 4A. By displaying the operation mode designations of "favorite settings" and "timer reservation," the user can designate one of the operation modes by a click operation.

The "management database" mode is the management database video track recording area F' of the video tape 36 (FIG. 3).
In the operation mode, the management data DavC (Fig. 4) is recorded in the management database audio track recording area F, □, or the recorded management data D1 is used to drive and control the video tape recorder main body 3.
When the "Management Database" item among the menu display items is clicked in step SP6, the PU8 sets a video cassette 35 having a tape on which management data D and v are recorded (this is called a management data tape) in step SP7. If the contents of the management database have been changed, it is determined whether the contents of the management database have been changed or not, and after executing various processes of the management database in subroutine RT1, if it has been set, it is determined whether the contents of the management database have been changed in step SP8. At SP9, processing is executed to rewrite the recorded data in the management database video track recording area Favv or the management database audio track recording area F□ with the changed management data.

In this way, the processing for the management database is completed, and in step 5 PIO it is determined whether the power has been turned off or not. When a negative result is obtained, the state returns to the above-mentioned command standby state, and when a positive result is obtained, step At 5PII, the input information processing program ends.

Upon entering the various processing routines RT1 for the management database described above, the CPU 8 executes step SP2 as shown in FIG.
1, after displaying the management data list on the display screen 6A of the remote controller 6 and the display screen 4A of the monitor 4, the system enters a command standby state.

At this time, "Label", "Reservation Cancellation", "
"Auto play", "Manual reservation", "Program information confirmation"
and "Management Data Reservation" items are displayed, and this makes it possible to specify that one item.

Here, "Label j item is volume information block Dv11 or program information block D□(
This represents an operation mode that can be set by selecting one of the volume information or program information included in the program information (Figure 4), and when the "Label" item is clicked in step 5P22, "Password" and "Recording" are displayed on the display screen. By displaying the items ``mode'', ``tape type j'', ``category'', and ``title j'', it becomes possible to select that one item.

Here, when the user clicks on the "Password" item,
The CPU 8 receives the volume information D in step 5P23.
To enable a user to rewrite password data recorded in item All of the VNX (Fig. 5).

Similarly, in step 5P24, the CPU 8 can designate the recording/operation mode recorded in item B8 of the program information Dr□ (FIG. 6) and write the recording mode data therein.

Also, cpus receives the volume information DwN! in step 5P25. Among the data indicating the type of video cassette recorded in the item AIO of FIG. 5, the tape type data can be rewritten.

In addition, the CPU 8 retrieves the program information in step 5P26.
□ The category code data recorded in item B6 (Figure 6) can be rewritten.

Further, in step 5P27, the CPU 8 reads the program information D.
The title data recorded in item B12 of □t (FIG. 6) can be rewritten.

In this way, the CPU 8 rewrites the data in the "password" to "title" items in steps 5P23 to 5P27, and then ends the processing of the management database when the "end" item is specified in step 5P28. Then, the process returns to the management database processing loop shown in FIG. 7 and enters the process of step SP8.

On the other hand, when the user clicks on the "cancel reservation" item in the command standby state where the management data list is displayed in step SP21 of FIG. Cancel all program reservations.

Also, if the user clicks on the first song that plays automatically,
PU8 receives the volume information in step SP31,
□ The playback order data of item A13 (FIG. 5) is played back 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, SF31 and 5P32 is completed, the CPU 8 executes the steps 5P28 and 5P29 described above.
and returns to the management database processing loop (FIG. 7).

Further, when the CPU 8 is in the standby state for a command to display the management data list in step SP21 of FIG.
enters the process of step 5P33, switches the display screen display in step 5P34, and proceeds to step 5P35.
, or in 5P36, 5P37, or 5P3B, volume information DvMX (Figure 5) and program information, □ (Figure 6)'s "recording permission" item, "saw flag" item, "category j item," title ” 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 5P3B is thus completed, the CPU 8 returns to the management database processing loop (FIG. 7) via steps SP2B 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 SP41.

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 the word input is selected as a result, the CPtJ8 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 word input item specified by the user.

Conversely, if graphic input is selected, the CP
U8 moves to step 5P43, displays the graphic designation item list on the display screen, and stores the 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 input process and returns to the management database processing loop shown in FIG.

At this time, the CPU 8 subsequently displays the "registration" item, the "change" item, and the "inquiry j item" on the display screen, and proceeds to step SP.
51. In 5P52 and 5P53, when the user clicks on the "Registration" item, "Change" item, or "Inquiry" item, the process to execute this starts.

Here, cpus processes the clicked item, and in steps 5P54, 5P55, and 5P56, the calendar reservation table, one-week reservation table, and one-day child table can be displayed according to the user's selection, respectively. The start time and/or end time of a reserved program is written on a calendar reservation table, weekly reservation table, or daily child table.

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.
In P6, ``By clicking on the management database j item, you can record, change, and record 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 j item,""Recording mode j item,""Noisecancellation" item, "rBS online" item, "Auto set" item, and "Tuner preset" item. ” item and “3rd line man power” are displayed, and these items are respectively displayed 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 PU8 ends the processing of the system setting processing loop and moves to the above-mentioned step 5PlO.

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" item, "user set" item, "character" item, and "timer reservation" item. ” item, “User level” item, “Message” item, and “Voice j item” are displayed on the display screen, and these items are respectively
When clicked on ゜5P76.5P77.5P7B or SF39, the CPU 8 executes the processing of 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 first cycle of timer reservation in step SP81, the CPU 8 displays the "Register" item and the "Change" item on the display screen.
Display the item and "Inquiry" item, and the user can proceed to step 5P.
82. When each item is clicked on 5P83 or 5P84, the display screen displays the items ``calendar reservation table j item'', ``1 week reservation table'' item, and ``1 day child table'' item. Then, when the user specifies one of them, CP
U8 is the calendar reservation table, one week reservation table, or one in step 5P85.5P86 or SP87 respectively.
By displaying the schedule table, the user can make a reservation for a program 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 CPtJ8 can reliably control the video tape recorder main body 3 based on the input data input by the user.

(G5) Recorded flag writing processing The video cassette 35 is attached to the video tape recorder main body 3, and the remote control controller 6 (first
When the management data mode command key 6F (Fig. 0) is turned on, the control management data processing CPU 8 changes the management data I).
The ay read mode is entered from step 5P90 (FIG. 12), and in step 5P91, the management database video track recording area F formed on the video tape 36 is read.
A Mama or management database audio track area F
IIIFA management data D&V to electromagnetic conversion circuit 33,
The data is read out via the playback circuit 37, playback switching circuit 38, and image recording decoder 52, and loaded into the register 44.

Subsequently, in step 5P92, the CPU 8 selects the "Recording start time" of the item B9 and the "Recording end time" of the item BIO, which are the bottom of the program information DPlx (FIG. 6), of the management data I)av read into the register 44. It is determined whether or not the same reservation information as the reservation information written at time J is stored in the reservation memory provided in the video tape recorder body 3, and when a negative result is obtained, step 5
At P93, the reservation information in the register 44 is written as reservation recording data in the reservation memory of the mechanism control CPUI 1, and the process moves to step 5P94.

If a positive result is obtained for this (this means that the reservation information written in the register 44 has already been written in the reservation memory of the mechanism control CPU II), the control management data processing The CPU 8 immediately moves from step 5P92 to step 5P94.

The control management data processing CPU 8 performs this step 5P94.
For example, the reservation information of four registered programs stored in the reservation memory of the mechanism control CPUI 1 is
As shown in FIG. 13, each program is graphically displayed as a list HYO with one line of graphic display elements, and the reservation status is displayed to the user.

When the current time reaches the recording start time written in the register 44, the control management data processing CPU 8 sends control information S6 to the video tape recorder main body 3 via the bus 10 in step 5P95, and controls the mechanism control CPU II. When the recording of the program is completed, the CPU 8
writes in the first and second bits of "various flags" (FIG. 14) in item 100B3 of the management data DAY recorded in the register 44 whether the recording ended normally or whether there was an abnormality.

Next, the control management data processing CPU 8 performs step 5P9.
In step 6, it is determined whether recording has ended normally from the recording end status recorded in item B3 of management data D and V, and if an abnormality has occurred during recording, the display on the monitor 4 is determined in step 5P97. An error message is displayed on the screen 4A and the display screen 6A of the remote controller 6, and the process moves to step 5P9B.

On the other hand, when recording ends normally, the CPU8
The process moves from step 5P96 to step 5P98 to erase the reservation information stored in the reservation memory of the mechanism control CPUI 1, and in step SP99, the "record" in item B9 of the management data [)at stored in the register 44 is deleted. "Start time" and "Recording end time" of item BIO are kept and the recorded flag of item B3 (14th
The data of the θth bit representing the logic “0” data (
(indicates that the program is currently reserved) to logic “
1" data (indicating that the program is currently being recorded), thereby changing the "Recording start time" and "Recording end time" as reservation information to "Recording information of the recorded program". Rewrite them as "Recording start time" and "Recording end time."

Here, when the user operates the eject key of the video tape recorder main body 3 and instructs to eject the video tape 36, the control management data processing CPU 8 performs step 5P1.
After rewinding the videotape 36 to the tape top position at 00, the management data Dat stored in the register 44 is transferred to the video recording encoder 51, the electromagnetic conversion circuit 33, and the magnetic head 34 to record the video on the videotape 36. The information is recorded in the management database video track recording area F avv formed on the tracks TA and TB.

Thus, the control management data processing CPU 8 performs step 5P.
At IOI, the videotape 36 is ejected and the process ends.

According to the above configuration, the recorded flag F□. After the recording of the program is finished, by rewriting the logical "o" data indicating the reservation status to the logical "1" data indicating the recorded status, for example, the "recording start time" written as reservation information in item B9 and BIO can be changed. ” and “recording end time” can be directly used as “recording start time” and “recording end time” as recorded information. In this way, there is no need to have data areas corresponding to each of the reservation information and the recorded information, and data rewriting can be minimized, thereby further simplifying data processing.

(G6) Other embodiments (1) In the above embodiment, the recorded flag F
Although the case has been described in which "recording start time" and "recording end time" as recording reservation information are managed as recorded information based on mIC, the present invention is not limited to this. This can be applied to recording reservation information such as "Title".

(2) In the above-described embodiment, the case where there is reservation information in step 5P94 is described, but the present invention is not limited to this, and when recording is performed manually because there is no reservation information, the control management data processing CPU 8 register 4 via
The present invention may be applied to the case where the data written in the management data memory No. 4 is used as reservation information.

(3) In the above embodiment, as the structure of the management data DAY, the volume information block I)vM and the program information block D□ were written in that order from the beginning position of the recording track. Various changes may be made, such as changing the arrangement order or, depending on the case, dividing them into smaller pieces and mixing them.

(4) In the above embodiment, the management database audio track recording area P'ava is stored on the video tape 36.
However, the insertion position is not limited to this and may be changed to other positions.

(5) In the above-mentioned embodiments, the case where the present invention is applied to a video tape recorder has been described, but instead of this, if the present invention is widely applied to consumer electronic equipment such as a so-called radio cassette player, the above-mentioned The same effect can be obtained as in the case of .

Effects of the Invention As described above, according to the present invention, recorded information is written as management data recorded in the management database recording area, so that a reserved program for a program can be changed simply by rewriting the recorded flag. Information can be used as recorded program information, and processing of recording and reservation information can be further simplified.
