B. Summary of the Invention The present invention provides an information recording and reproducing device that can reproduce recorded information according to a preset reproduction order as necessary by recording reproduction order data of recorded information, and The usability of the device can be improved.

C. Prior Art Conventional consumer video tape recorders record multiple programs on a video tape that extends in the horizontal direction.
A cue signal is recorded at the beginning value l of each program. For example, when a user wants to play a desired program from a recorded tape, the user first sets the video tape recorder to search mode and cues the video tape. After fast-forwarding to a position where the program signal can be reproduced, the user first switches to the reproduction 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 videotape recorder, information about a plurality of programs is recorded for each program only at the videotape position where each program is recorded. When users check the program they want to play, decide on the program they want to play, or search for the program they want to play, they actually spend a lot of time searching the video tape recorder repeatedly until they find the program they want to play. There is the complication of having to perform tasks such as fast-forwarding a videotape over a long period of time.

Especially in the case of series programs, when the first broadcast program and the rebroadcast program are mixed and recorded.
If you try to play the videos in the original broadcast order, you will have to repeat these complicated tasks, which makes it inconvenient to use.

The present invention has been made in consideration of the above points, and aims to propose an information recording/reproducing device that can solve these problems all at once and improve usability.

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-direction cursor keys 6B, a specification signal regarding the display item can be manually input by operating the execution key 6C. It is made to be obtained.

Further, the remote controller 6 has a normal operation command 10-6D, 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. The operation mode of the video tape recorder 1 can be specified for each user.

Step SP of the input information processing program RTO in FIG.
In step 1, 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 1 enters the standby state for commands with the current time set.

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).
avv or the management database audio track recording area FAW&, or in which the management data Dav (FIG. 4) is recorded, or the recorded management data D0 is used to drive and control the video tape recorder main body 3.

Here, in step SP6, the CPU 8 selects "When the management database j item among the menu display items is clicked, in step SP7 the video cassette 35 having the tape on which the management data Dav is recorded (this is called a management data tape) is set." If it is set, after executing various processes for the management database in subroutine RTI, in step SP8 it is determined whether the contents of the management database have been changed, and if they have been changed. In step SP9, the management database video track recording area F'av
v or management database audio track recording area F
Processing such as rewriting the recorded data of An with the changed management data is executed.

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.

Regarding the various processing routines RTl of the management database mentioned above, the CPU 8 executes step 5P2 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, the "label" item is the volume information block DVM or program information block DPI (of the management data DAv).
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'', ``Category'', and ``Title'', it becomes possible to select one of the items.

Here, when the user clicks on the "Password" item,
The CPU 8 receives the volume information D in step 5P23.
The password data recorded in the item All of v, x (FIG. 5) can be rewritten by the user.

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

Also, cpus receives volume information D□! 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, CPtJ8 receives the program information D in step 5P26.
The category code data recorded in item B6 of P□ (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 pmx (FIG. 6) can be rewritten.

In this way, the CPU 8 rewrites the data of the "Password j item" to "Title" item in steps 5P23 to 5P27, and when the "end" item is specified in step 5P28, ends the processing of the management database and returns to step 5P29. 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 5P21 of FIG. Cancel all program reservations.

Also, when the user clicks on the "Autoplay" item, c
pus switches to program playback mode, and step S
At P31, the programs are played back in the order determined by the playback order data of item A13 of the volume information Df□ (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 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).

Furthermore, when the CPU is in the standby state for commands to display the management data list in step 5P21 of FIG.
The processing in step 5P33 is started, the display on the display screen is switched in step 5P34, and the process is performed in step 5P35.
, or 5P36, 5P37, or 5P38, volume information Dvxx (Fig. 5) and program information D
The display mode becomes such that the recorded contents of the "recording permission" item, "viewed flag" item, "category" item, and "title" item of v*x (FIG. 6) 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 j item. This 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, in the command standby state where the management data list is displayed, if the user clicks on the first page of the management data reservation, the CPU 8 enters the management data subroutine RT3 and returns to the flowchart shown in FIG. 9 which authorizes a part of the processing procedure. Management data reservation processing procedure R for switching the reservation mode as shown
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, 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 5P41, 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 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 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, "change" item, and "inquiry" item on the display screen, and then 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.

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 table in accordance with 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 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.
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.

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" item, "Noise cancellation" item, "BS online" item, "Autocella 1j item," and "Tuner preset" item. ” item and “Line manpower” item are displayed, and these items can be set in step 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, the CPU 8 in step 5P71 says, ``When you click on the desired setting j item, the display screen displays the ``Screen Display'' item, ``Management Database'' item, ``User Set'' item, ``Character'' item, and ``Timer Reservation'' item. '' item, ``user level j item, ``message'' item, and ``audio'' item are displayed on the display screen, and these items are respectively
When clicked on 5P76.5P77.5P7B or 5P79, the CPU 8 executes the process for each item, and when the process is completed, the process moves to step 5PIO described above.

Further, 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 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 "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 makes a calendar reservation table, a weekly 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 5pio.

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

(G5) When recording one or more programs P1, P2, P3, etc. on the videotape 36, the index data recording control management data processing CPU 8 determines the recording start point and recording end of each program. The data representing the points as the program start address value and the program end address value from the top of the tape is stored in the program information D□8 (Figure 6).
By this, when performing processing such as playing back or re-recording each program of the recorded video tape 36, it is recorded in the start address field B1 and end address field B2 of the program. The system is designed to confirm the recording position without running the tape.

Furthermore, management data Dav input by the user as necessary.
The contents of the volume information block I)vx can be updated, and the playback order data etc. can be updated.

First, the control management data processing CPU 8 manually inputs the data of each item of the management data Dav (FIG. 4) as input/output information S4 via the remote control transmitter/receiver 7 by the user operating the remote controller 6. When the video cassette 35 is ejected, the data is stored in the register 44, and the mode is switched to the management data recording mode, for example, when the video cassette 35 is ejected. Here, the control management data processing CPU 8 holds the management data Day in the register 44, and writes the management data I) av in the register 44 as the write management data S25. i is sent to the tracing line recording encoder 51, converted into a data video signal S42 by the image recording encoder 51, and supplied to the recording circuit 32 via the recording switching circuit 31.

At this time, the recording circuit 32 processes the data video signal S42 in the same way as the recorded video signal S1, and sends the data video signal S42 to the video tape 36 through a video electromagnetic conversion circuit that constitutes the electromagnetic conversion circuit 33 and a video head that constitutes the magnetic head 34. Management data D and V are recorded on recording tracks TA and TB (FIG. 3) as signals corresponding to one field's worth of video signals.

Thus, on the video tape 36, for example, the management database video track recording area Fa is located at the top of the tape.
vv (Fig. 3) is formed, and the management database video track recording area FMWV is created as shown in Fig. 12 (B).
As shown in FIG. 2, management data video signals VDh&V are recorded.

Furthermore, the control management data processing CPU 8 transfers the mark recording data as control signal recording data 344 to the CTL recording encoder/decoder 54, and
The recording encoder/decoder 54 converts this into a data control signal 346 and sends a control signal configuring the electromagnetic conversion circuit 33 to the control signal head configuring the electromagnetic conversion circuit and the magnetic head 34 in order to generate a control signal for the video tape 36. It is recorded on the recording track TCT as a recording start point mark signal MKos (FIG. 12(C)).

Thereafter, the control management data processing CPU 8 records the control signal CT in the control signal recording track TCT by transferring the control signal as the control signal recording data S44, and also records the control signal CT in the control signal recording track TCT, and also records the control signal CT in the control signal recording track TCT (see FIG. 12(B)). ), the control signal recording data 344 is given again at the timing of the recording end point, thereby recording the recording end point mark signals MK and E.

In the program recording mode before switching to the management data recording mode, the control management data processing CPU 8 sequentially records the program P1 in the video recording track TASTB of the video signal recording area Fve (FIG. 3) following the management database video track recording area F AWV. , P2, P3...

PU8 is the program video signal VDFI, VD, , VD, 1
When timing the recording start point and recording end point, the recording start point mark signal MK
, MKP□, MK, , s... and recording end point mark signals MKFI□, MKP8t, MK,.・・・
...(Figure 12(C)) is recorded.

In this embodiment, the mark signals M K o s and M K
@t, MK□, and MK□g, MKpzs and MK
, □, MKIII and M K P. . . . are respectively tape position address values from the tape top reference point of the video tape 36, and these tape position address values are used, for example, to mechanically control the value of a tape counter circuit provided in the video tape recorder body 3. The information is obtained by transferring the data to the control management data processing CPU 8 via the CPU II.

Therefore, mark signals MK□, , MK□0, MK□8, M
In K□, it is used as index data representing the first position l of each program P1, P2, . . . corresponding to the system program number B4 recorded in the management database video track recording area F'av. It is possible,
The mark signals M K F l s, M Kp+i,
By sequentially counting M Kegs, MK□, from the tape top reference point, it is possible to detect the system program number of each program P1, P2, . . . sequentially recorded from the tape top reference point. ing.

On the other hand, in the playback order data, the system program number (Figure 6) to be played back sequentially is recorded from the 1st byte to the 32nd byte, and when the user specifies and inputs the playback order, in the management data recording mode. , the system program numbers of the programs recorded on the video cassette are recorded in the order of the specified input, starting from the first byte.

On the other hand, if the user does not manually specify the playback order,
In the management data recording mode, the system program numbers of the programs recorded on the video cassette are recorded in the recording order starting from the first byte.

Furthermore, when the user specifies and inputs the playback order in the case of splicing and recording programs, in the management data recording mode, the system program number of the program recorded on the video cassette is sequentially input from the first byte in the order of the specified input. On the other hand, if the user does not input a designation, the system program number of the value following the final value of the playback order data before update is recorded as the playback order data of the newly recorded program.

At the same time, the control management data processing CPU 8 updates the repeat recording count item A2, update date and time item A6, etc. in the management data recording mode when the program is to be shot and recorded continuously.

In this way, the playback order can be determined based on the playback order data specified and inputted in advance when recording the program. You can manage recorded programs by specifying them in advance.

Therefore, in addition to the playback order data, each program information start address data item Bl, mark signals MK□s, MK□
By sequentially reproducing the recorded programs based on t, M Kegs, and M Kpts, the programs can be easily reproduced in a preset reproduction order, and the usability of the video tape recorder 1 can be improved.

(G6) Program playback mode As described above with reference to FIG. 8, the control management data processing CPU 8 is configured to operate when the user selects the "auto playback" item in the command standby state in which the management data list is displayed on the display screen in step SP21. Click to switch to program playback mode and proceed to auto playback processing step SP3.
Execute 1.

That is, when the recorded video cassette 35 is loaded into the video tape recorder main body 3, the control management data processing C
The PU 8 enters the management database playback mode while communicating with the mechanism control CPU 11, and transfers the data video signal picked up from the management database video track recording area F, MA of the video tape 36 to the magnetic head 34,
The data is read out via the video electromagnetic conversion circuit 33, the playback circuit 37, the playback switching circuit 38, and the image recording decoder 52, and written into the register 44.

Thus, the register 44 contains the management data Day (Fig. 4).
are held as unique management data in the videotape 36, and playback order data and each recorded program P1,
Program information about P2, P3..., □ (
(Fig. 6) is maintained.

Thus, each program information D FIK start address item B1
and programs P1, P2, P3-・ in the end address field B2.
Recording start point and recording end point MKPl, and M
Kpwt , M Kv*s and MK□, , MK, ,
, MK□1, . . . can be centrally managed in the register 44 as addresses representing positions on the video tape from the tape top reference position of the video tape 36, respectively.

Here, as shown in FIG. 13, in the program playback mode, the CPU 8 performs steps 5P90 to 5P90.
Proceeding to P91, the system program number is detected based on the playback order data stored in the register 44, and then the start address of the system program number is detected.

At the start of program reproduction, the CPU 8 detects the system program number recorded in the first byte of the reproduction order data.

Subsequently, CPtJ8 moves to step 5P92 and determines whether a system program number is specified in the playback order data.

At the start of program playback, a positive result is obtained by detecting the program with the system program number recorded in the first byte of the playback order data, and the CPU 8
The process moves to step 5P93, where the control information S6 is output to the mechanism control CPU 11 via the bus 10, and the operation mode of the video tape recorder 1 is switched to the playback mode.

Here, when the mark signal MKF Ig is detected, the CPU 8 determines whether the program recorded following the mark signal MK□3 is the program with the system program number recorded in the first byte. , If a positive result is obtained here, the process moves to step 5P94.

Here, the CPU 8 maintains the reproduction mode until the following mark signal MK□3 is detected, and then proceeds to step 5P92.

In this way, when the program recorded first on the tape top side is designated as the first program in the playback order, the CPU 8 executes step 5.
By executing the processes P92-SP93-5P94, the video tape recorder 1 reproduces the program.

As a result, CPtJ8 detects the system program number recorded in the subsequent playback order data and then performs step 5P92.
After that, the process moves to step 5P93.

On the other hand, if the system program number of the first program recorded on the tape top side is not recorded in the first byte of the playback order data, or the system program number of the first program recorded on the tape top side is When playing the program with the system program number specified in the subsequent playback order data, the CPU 8 obtains a negative result in step 5P93, and the CPU 8 obtains a negative result in step 5P93.
Moving on to P95.

Here, the CPU 8 determines whether the system program number to be reproduced next is on the tape end side, and if a positive result is obtained here, the process moves to step 5P96, and then the mark signal MK
After fast forwarding the magnetic tape 36 until p*s is detected, the process moves to step 5P97.

Here, the CPU 8 determines whether or not it is the end of the tape. If a negative result is obtained, the CPU 8 moves to step 5P93 and determines whether or not it is the system program number specified by the playback order data.

In this way, when playing back the program first recorded on the tape top side and then skipping the subsequently recorded program, or when playing back the desired program while skipping the first recorded program on the tape top side. , sequential step 5P
By repeating steps 93-3P95-3P96-3P97-3P93 and obtaining an affirmative result in step 5P93 for the system program number specified by the playback order data, the programs can be sequentially played back in the prespecified order.

On the other hand, if a negative result is obtained in step 5P95, the CPU 8 moves to step 5P98, and in step 5PQ
After rewinding the magnetic tape 36 until the mark signal MK□3 is detected, contrary to step 6, it is determined whether the tape is at the top or not in step 5P99.

If a negative result is obtained here, the CPU 8 moves to step 5P.
93, it is determined whether or not the system program number is specified by the playback order data.

If the system program number that has been reproduced twice is repeatedly specified, an affirmative result is obtained, and the CPU 8 moves to step 5P94 to reproduce the program again.

On the other hand, if the system program number of the program recorded on the tape top side following the once played program is specified, a negative result is obtained again in step 5P93.
The CPU 8 moves to step 5P95.

In this way, if the system program number of the program recorded on the tape top side following the program played twice is specified, steps 5P93-SP95-3P are performed sequentially.
98-3P99-3P93 are repeated, and step 5P is executed at the system program number specified by the playback order data.
If a positive result is obtained in step 93, the magnetic tape can be rewound and the programs can be played back in sequence in a pre-specified order.

Therefore, by sequentially repeating the processing procedure, it is possible to repeatedly reproduce one program, for example, in the order specified by the reproduction order data, or to reproduce a series of programs recorded in different order in the original broadcast order.

On the other hand, if the system program number of a program that is not recorded on the video cassette 35 is incorrectly specified,
The CPU 8 obtains an affirmative result in step 5P97 or step 5P99, and moves to step 5P100.

Here, the CPU 8 displays an error message on the display screen 6A of the monitor device 4 and the remote controller 6, and then moves to step 5 PIOI to end the processing procedure.

Thereby, the CPU 8 returns to a state where it waits for subsequent input from the remote controller 6 or the keyboard 12.

On the other hand, the CPU 8 sequentially reproduces the programs with the system program numbers specified by the reproduction order data, and when the reproduction of all the specified programs is completed, a negative result is obtained in step 5P92, and the CPU 8 moves to step 5P102.

Here, the CPU 8 outputs control information S6 to the mechanism control CPU 1 via the bus 10, and
After rewinding or fast forwarding to the program playback start position,
The process moves to step 5P103 and ends the processing procedure.

According to the above configuration, by recording the playback order data of the program recorded on the video cassette on the tape top,
If necessary, recorded programs can be quickly played back in accordance with a playback order preset based on the playback order data, and the usability of the video tape recorder can be improved.
