In particular, the purpose of the present invention is to make it easier to manage the number of recordings, reservations, etc. on videotape.

B. Summary of the Invention The present invention further simplifies the management of various programs by allowing a video tape recorder to record and reproduce management data corresponding to a program on a video recording track.

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 of each program. For example, when a user wants to play a desired program from a recorded tape, the user must first set the video tape recorder to search mode and use the video tape to cue. After fast-forwarding the signal to a position where it can be played back, the user first switches to playback mode and checks whether it is the program he or she wants to watch.

Problems to be solved by the invention D 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 video tapes or unrecorded video tapes, or when managing so-called series programs recorded over multiple video channels, in reality, each video tape is recorded individually. 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 makes it possible to significantly simplify the management of programs when recording, reserving, etc. (this is referred to as recording or reserving) a program. This is an attempt to propose a video tape recorder.

E! II! Means for Solving the Problem In order to solve this problem, the present invention provides video recording tracks TA and TB formed on the video tape 36.
and a video tape recorder capable of recording one or more programs on audio recording tracks CH1, CH2;
A management database recording area FAVA is formed in a predetermined position of 2, management data DAV corresponding to each program is recorded in this management data recording area FAVA, and data can be recorded on the videotape 36 based on the management data DAv. Allows you to manage each program.

1) In the management database recording area F AVA formed on the audio recording tracks CHI and CH2, management data I) av regarding programs recorded and reserved on the video tape 36 is recorded, so that the user can By simply reproducing the management data DAV in accordance with the management data DAV, it is possible to easily grasp information about the programs recorded and reserved on the videotape 36 as information unique to each videotape 36, and the management data DAV By being able to rewrite the program as necessary, program management can be made even easier.

(G4) Video tape recorder setting processing CPU 8 uses control management data processing unit 5,
The video signal processing section 2 and the video tape recorder main body 3 are processed by the processing program RTO shown in FIGS. 7, 8, and 9.
By processing according to RTI and RT31, it is controlled to the operating state 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-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.

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. 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 Figure 7
In I, CPU8 is! Waits for # to be turned on, and when a positive result is obtained, t is turned on in step SP2.
It is determined whether or not the power-on operation is the first time, and if it is the first time, the message "Set the time" is displayed on the display screen 4A of the monitor 4 by sequentially executing steps SP3, SF3, and SF3. After displaying on the display screen 6A of the remote controller 6, the current time is set according to the system setting operation mode, and a message "Time has been set" is displayed on the 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, when the CPU 8 is 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 display screens 6A and 4A display "Management database", 'System settings', 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 data storage" mode is the management database video track recording area F of the video tape 36 (Fig. 3).
An operation mode in which management data DAv (FIG. 4) is recorded in the AVV or management database audio track recording area FAvA, or the recorded management data DAV is used to drive and control the video tape recorder main body 3,
In step SP6, when the "Management database j item" is clicked among the menu display items, the CPtJ8 checks in step SP7 whether a video cassette 35 containing a tape on which management data DAV is recorded (this is called a management data tape) is set. Decide whether or not
When set, after executing various processes of the management database in subroutine RT1, step SP
In step SP8, it is determined whether or not the content of the management database has been changed, and if it has been changed, in step SP9, the management database video track recording area FAVV or the management database audio track recording area FAV is determined.
Processing such as rewriting VA recorded data with 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 t source is turned off or not. When a negative result is obtained, the process returns to the above-mentioned command standby state, and when a positive result is obtained, the process returns to the command standby state. In step 5 PII, the input information processing program is ended.

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, the "Label" item is the volume information block DVM or program information block D□ (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 Figure 4).In step 5P22, when the ``Label j'' item is clicked, ``Password'' and ``Recording'' will be 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, if the user clicks on the 14 Password items,
cpus receives the volume information D in step 5P23.
The user is allowed to rewrite the password data recorded in the item All of vMX (FIG. 5).

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.

Further, the CPU 8 is configured to be able to rewrite the tape type data among the data representing the type of video cassette recorded in the item AIO of the volume information DvNl+ (FIG. 5) in step 5P25.

Further, the CPU 8 in step 5P26 sets the program information D□
The category code data recorded in item B6 of Figure 6) can be rewritten.

Furthermore, cpus receives program information D in step 5P27.
The title data recorded in item B12 of rmx (FIG. 6) can be rewritten.

In this way, the CPU 8 rewrites the data of the "Password" item to "Title" item in steps SP23 to 5P27, and when the "end" item is specified in step 5P28, the CPU 8 ends the processing of the management database and steps 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, in the command standby state where the management data list is displayed in step SP21 of FIG. Cancel all program reservations.

Also, when the user clicks on the "Autoplay" item, C.
PU8 sets the volume information Dv in step 5P31.
, l, + (FIG. 5), the reproduction order data of item A13 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, CPL;8 is the step 5P28.5P2 described above.

Further, when the CPU 8 is in the standby state for commands to display the management data list in step 5P21 of FIG.
enters the process of step 5P33, switches the display screen display in step 5P34, and proceeds to step 5P35.
, or 5P36, 5P37, or 5P38, volume information Dv,x (Fig. 5) and program information Dp
*x (Figure 6) The display mode becomes such that the recorded contents of the ``recording permission item,'' ``viewed flag'' item, ``category'' item, and ``title'' item can be confirmed or rewritten.

In this example, "recording permission j item,""sawflag"
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 "1 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 device and a graphic designated item list consisting of graphic manual items that represent designated items using graphic elements such as Roman letters, numbers, and symbols as usual are prepared, and the CPU 8 uses them in step SP41. The user is made to select and specify either word input or graphic input as the reservation screen to be used.

If word input is selected as a result, the CPU 8 moves to step SP42, 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 schedule according to the user's selection in steps 5P54, SF35, 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.
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 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 on ``System Settings'', the display screen displays ``Current time'' item, ``Sleep timer J item, ``Recording mode'' item, ``Noise cancellation'' item, RBs online'' item, ``Auto set'' item, ``Tuner preset'' item, and ``Tuner preset'' item. 1J item and "Line manpower" item are displayed, and these items are respectively set in step SP62.5P63.5P64.5P6.
5. By clicking on SF36.5P67.5P68 or 5P69, you can set the operating conditions of each part of the system, and when the setting process is finished, C
PtJ8 ends the processing of the system setting processing loop and moves to the above-mentioned step 5 PIO.

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 j item,'' and ``audio'' item are displayed on the display screen, and these items are respectively processed in step SP72.5P73.5P74.5P75.
．． When clicked on 5P76.5P77.5P78 or 5P79, the process for each item is executed, 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 5P81, the CPU 8 displays "Register j item, Change J item" on the display screen.
Display the item and "Inquiry" item, and the user can proceed to step 5P.
82.5 When each item is clicked in P83 or SF34, the "calendar reservation table j item,""weekly reservation table" item, and "daily child table" 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 step 5P85, SF36, or 5P87, 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 CPU 8 can reliably control the video tape recorder main body 3 based on the input data input by the user.

rc5)? Recording of management data DAv into the management database audio track recording area F AVA The audio recording encoder 53 (FIG. 1) converts the management data DAV into a data audio signal and records the audio on the video tape 36 using the configuration shown in FIG. The audio recording decoder 54 manages data audio signals reproduced from the video tape recorder 36 in the same signal format as the audio signal by the configuration shown in FIG. Data D is converted into AV and taken into the control management data processing CPU 8.

That is, the audio recording encoder 53 writes the management data DAv stored as part of the basic data in the basic data memory 43 (FIG. 1) as the management data S27 based on the control information S5 of the control management data processing CPU 8. The data audio signal 3 is transferred to the encoder circuit 53A.
41, and this data audio signal S41 is sequentially passed through the recording switching circuit 53B and the recording circuit 53C as the recorded audio signal S42 as 1!1TIf! Audio recording tracks CHI and CH2 (
Figure 3) Record above.

As a result, the video tape 36 has a management database audio track recording area FAv at the top of the tape.
A (Figure 3) is formatted.

On the other hand, when the control management data processing CPU 8 enters the management data reproduction mode, the audio recording decoder 54 controls the audio recording tracks CHI and C on the video tape 36.
The data audio signal picked up by the audio head constituting the magnetic head 34 from H2 is received by the reproduction circuit 54A as a reproduced audio signal S43 via the audio electromagnetic conversion circuit 33A of the electromagnetic conversion circuit 33, and is sent to the reproduction circuit 54A via the reproduction switching circuit 54B to the decoder. Supplied to circuit 54C.

The decoder circuit 54C converts the manually input data audio signal 344 into successive management data 32B and sends it to the bus 9. At this time, the control management data processing CPU 8 writes the read management data S28 sent from the decoder circuit 54C into the basic data memory 43.

In the configuration shown in FIG. 12, the control management data processing CPt
When J8 receives the management data write command, it sends a cue command to start writing of the videotape 36 to the mechanism control CPU II (Fig. 1), and
In response to this, the video tape 36 is fast-forwarded to a predetermined cue position.

Subsequently, the control management data processing CPU 8 is connected to the recording switching circuit 5.
By applying a recording switching signal 345 to the encoder circuit 3B, switching control is performed so that the data audio signal 341 of the encoder circuit 53A can be supplied to the recording circuit 53C.

Incidentally, the recording switching circuit 53B normally transfers the recording audio signal 346 obtained from the audio circuit 55 to the recording circuit 53C.
Thus, audio signals can be recorded on the audio recording tracks CH1 and CH2 of the video tape 36.

In this state, the control management data processing CPU 8 supplies the management data DAv read from the basic data memory 43 to the encoder circuit 53A as write management data S27 consisting of an FSK modulated signal as shown in FIG. The data audio signal S41 obtained in the recording switching circuit 53B, the recording circuit 53C, and the audio recording track CHI, C of the video tape 36 are transferred via the recording switching circuit 53B, the recording circuit 53C, the audio [magnetic conversion circuit 33A, and the magnetic head 34]
Record it in H2 (Figure 3).

Thus, when the recording of the management database audio track recording area FAVA on the video tape 36 is completed,
The control management data processing CPU 8 is a mechanism control CPU.
The management data recording mode is reset by outputting a management data recording end command to the UI 1, and the recording switching circuit 53B is switched to the audio circuit 55 side by the recording switching signal S45, thereby ending a series of management database recording processing. .

On the other hand, when receiving a management database reproduction command, the control management data processing CPU 8 is transferred to the mechanism control CPU 8.
A management data cue command is supplied to II.

At this time, the CPU II for mechanism control is videotape 3.
By driving 6 to locate the beginning, the recording head position of the management database audio track recording area FttvA (FIG. i3) is located.

Subsequently, the control management data processing CPU 8 sends a reproduction switching signal S47 via the bus 9 to switch the reproduction switching circuit 34B to the decoder circuit 54C side.

At the same time, the control management data processing CPU 8 controls the video tape recorder main body 3 to an audio reproduction state by supplying an audio reproduction start command to the mechanism control CPU II.

In this way, the management data DAV recorded in the management database audio track recording area FAVA of the video tape 36 is transferred to the decoder circuit 54C via the magnetic head 34, the audio TM conversion circuit 33A, the playback circuit 54A, and the playback switching circuit 54B. Audio signal S44
Supplied as. At this time, the control management data processing CP
U8 writes the read management data 328 output from the decoder circuit 54C into the basic data memory 43 via the bus 9.

When the reproduction of the management data DAv is finished in this way,
The control management data processing CPU 8 switches the reproduction switching circuit 54B to the audio circuit 55 side using the reproduction switching signal 347, and outputs an audio reproduction end signal to the mechanism control CPU II, thereby completing a series of management database reproduction operations.

According to the above configuration, management data regarding programs recorded and reserved on the video tape 36 is written to the management database audio track recording area FAVA formed on the audio recording tracks CHI and CH2 of the video tape 36, By making it possible to perform confirmation and change processing, it is no longer necessary to perform complicated tasks such as checking the contents of each program by running the videotape in search mode or playback mode each time, unlike in the conventional case. can be eliminated.

In this way, by allowing each videotape to hold a variety of management data as unique management data DAv, the internal functions of the videotape recorder itself can be made even more multifunctional, and it is also possible to construct a system with external equipment. This allows the video tape recorder to function as the center of the system.
