Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to a system for managing a library of video tapes.

<Prior Art> Generally, unlike audio tapes, the recorded content of video tapes is often changed. However,
Video tapes do not have a function to manage their recorded contents (recording start time, recording end time, recording date, recording channel, standard/3x recording mode, recording title, etc.). A person must write the recorded content on the label attached to the tape cassette.

To manage the recorded contents of multiple video tapes, it is necessary to create a list in a notebook.

However, it is extremely troublesome to rewrite the labels and lists each time the recorded content is changed.

Therefore, it is possible to record the recorded contents on the video tape itself. For example, an index is set at the beginning of the tape, and when the recording of one program is finished, the tape is rewound to the beginning and the index is added. Necessary items such as recording contents such as recording start time, recording end time, recording date, recording channel, or recording title are recorded. When playing back, the recorded content is read out from the index and displayed to inform the user of the recorded content. The user determines what content is recorded on which part of the tape, fast-forwards the tape to the part he wants to play, and starts playing. By displaying the recorded content in the same way when recording another program, you can judge which part can be deleted by looking at the displayed recording start time, recording end time, recording channel, etc. It provides support for operations such as setting up programs for recording.

As another countermeasure, for example, as disclosed in Japanese Utility Model Application Publication No. 60-26689, a method has been proposed in which a magnetic tape is pasted on the surface of a tape cassette and recorded contents are stored on this magnetic tape. has been done. In this case as well, during playback or recording, the recorded content is read out from the magnetic tape and displayed to assist the playback or recording operation.

<Problem to be solved by the invention> However, in the method of providing an index at the beginning of the tape,
Every time you want to read out and display recorded content as part of playback or recording preparation work, you must first rewind the tape to the beginning, and after checking the recorded content, you must fast-forward to the desired tape position. In addition, when one program ends, the tape is rewound to the beginning and the recorded content is stored in the index, so the time interval between the two programs is close to each other. If you continue to record a program, another program will have already started within the time required to rewind and fast-forward the tape to the end of the previously recorded program, and the beginning of that program will be overwritten. Parts cannot be recorded.

If the end of the tape is reached during recording and the tape is replaced with another tape to continue recording, the recorded contents cannot be recorded in the index of the previous tape.

As described above, the system in which an index is provided at the beginning of the tape has the problem that the usage pattern is significantly different from the current one, and the usability is rather deteriorated.

The method of installing magnetic tape in a tape cassette solves the above-mentioned problems associated with cueing, but the recorded content recorded on the magnetic tape is only for one videotape, and can be recorded on multiple videos. Since the recorded contents of the tapes are not comprehensively recorded, there is a problem that library management is not possible.

The present invention was devised in view of the above circumstances, and it is an object of the present invention to provide a system that is easy to use and that can manage a library of a plurality of video tapes.

Means for Solving the Problems> In order to achieve the above objects, the present invention has the following configuration.

That is, the tape management video system of the present invention includes a number sticker, a tape number reading device, an input device, a recorded content storage device, and a display controller, and the number sticker is attached to each tape cassette. It indicates the tape number of each tape cassette, and the tape number reading device reads the tape number from the number sticker and sends it to the CPU.The input device indicates the recording content to be registered in the recording content storage device at the time of recording. The recorded content storage device is used to register recorded data in which the tape number read from the number sticker at the time of recording is associated with the recorded content from the input device, and the display controller is used to input recorded content storage device. This controls the display of recorded data read from the device.

<Operation> Recorded data for a plurality of video tapes can be registered in the recorded content storage device in its entirety.

Of course, since the recorded content storage device is independent from each video tape, it is not necessary to rewind to the beginning of the tape each time when registering or reading recorded data, making it easy to use.

<Example> Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 is a block diagram of a tape management video system according to an embodiment of the present invention.

This tape management video system includes a tape number reading device 1, a recorded content storage device 2, a CPU 3, software 4, a working memory 5, a display controller 6, a video section 7, an input/output device 8, and an input/output device 8. device 9;
It consists of a number sticker 10. The video section 7 is
It includes a recording/reproducing head 7a, a tape point sensor 7b, and a control trunk read/write section 7C.

The number sticker 10 has 4 x 4 squares as shown in Figure 2, and the number is given by a different number depending on which square is filled in black. This number sticker 10 is attached to a predetermined position on the tape cassette 11.

The tape number reading device 1 reads the tape number from the number sticker 1°, and as shown in FIG. and phototransistor I
A light emitting/receiving system consisting of C is provided. Sixteen such light emitting/receiving systems are provided in a 4×4 matrix, corresponding to each square of the number sticker 10, to constitute the tape number reading device 1.

This tape number reading device l differs from conventional devices in which a magnetic tape is installed in a tape cassette; it is read-only and does not have a writing function; The video deck had to be significantly modified by adding a drive mechanism to move it along the magnetic tape and securing a stroke space for the drive mechanism, but the tape number reading device 1 of this embodiment is capable of reciprocating It does not move (it is installed in a fixed position), so the modification of the video deck does not need to be very large-scale.

The recorded content storage device 2 includes an IC card 2a and a reader/writer 2b. The IC card 2a is used to register a large amount of data in units of recorded data in which a tape number is associated with the recorded content of each program in the tape cassette 11 corresponding to the tape number. The recording contents include a recording tape point, a recording title, a recording start time, a recording end time, a recording date, a recording channel, and a standard 1/3 recording mode.

The working memory 5 contains the tape number, recording start time, recording end time, recording date, recording channel, and mark 1! /3x recording mode, recording title, recording tape point, etc. are temporarily stored.

The input device 9 includes an input operation section installed on the video deck, an input operation section installed on a remote control device (not shown), and a keyboard connected to the video deck. The first two input operation units are for inputting each data of recording tape point, recording title, recording start time, recording end time, recording date, recording channel, and standard 73x recording mode as program data for scheduled recording. It is. The keyboard is used to input the recording title.

The display controller 6 controls the video output signal from the recording/reproducing head 7a, the on-air broadcast video signal, or the tape number and recording content data from the recorded content storage device 2, and outputs an image output signal to a CRT (not shown). This is what is output as.

The tape point sensor 7b in the video section 7 detects the current position of the tape, that is, the tape point, using a tape remaining amount calculating device (not shown). There are various methods for detecting tape points, but here they are expressed in parts per thousand, where the total length of the tape is 1000. The control trunk read/write unit 7c reads header signals from the control trunk of the video tape and writes header signals to the tracks.

The input/output device 8 inputs the tape point signal from the tape point sensor 7b and the header signal from the control track read/write unit 7c and outputs it to the CPU 3, and also outputs the header signal input from the CPU 3 to the control track read/write unit. This is an interface for outputting to the section 7c.

The CPU 3, in cooperation with the software 4, operates a tape number reading device 1, a recorded content storage device 2, and a working memory 5.
, and controlling the display controller 6, as well as outputting data to and inputting data to and from the tape number reading device l, recorded content storage device 2, working memory 5, input/output device 8, and input device 9, It is a microcomputer central processing unit that controls the entire system.

Next, the operation of the tape management video system of this embodiment will be explained.

[i1 Writing Recorded Data When the tape cassette 11 is loaded into the video deck, the software 4 is activated and the CPU 3 requests the tape number reading device 1 to read the tape number. In accordance with this request, the tape number reading device 1 reads the tape number of the tape cassette 11 from the number sticker 10 and sends it to the CPU 3. The CPU 3 receives the tape number and stores it in the working memory 5. The user is
The input device 9 is used to input recording contents, that is, recording start time, recording end time, recording date, recording channel, recording mode (standard 73 times), and recording title. CPU3 is
The input or set data is stored in the working memory 5. Note that it is not necessary to input the recording title.

The CPU 3 starts recording when the recording start time comes, but
At the initial stage, the tape point at which recording starts is read from the tape point sensor 7b via the input/output device 8 and stored in the working memory 5. When the recording end time arrives and the recording is stopped, the CPU 3 reads the tape number and the recorded content from the working memory 5, transfers it to the reader/writer 2b of the recorded content storage device 2, and transfers it to the IC card 2a. Register. The registered recording contents are a recording tape point, a recording title, a recording start time, a recording end time, a recording date, a recording channel, and a standard/3x recording mode. However, the recording title may not be included.

The above explanation is for scheduled recording, but the explanation is almost the same for normal recording by manual operation.

However, the only difference is that there is no need to input recording contents using the input device 9 prior to recording. In addition, if a recording title is required, it can be input prior to recording.0 In the case of a normal edge picture, the CPU 3 inputs the recording tape point, recording start time, recording date, recording channel, etc. and the standard/3x recording mode are stored in the working memory 5, and when recording ends, the data read out from the working memory 5 and the recording end time are transferred to the reader/writer 2b and registered in the IC card 2a.

As described above, when registering recorded data (tape number and recorded content) in the IC card 2a, it can be registered at the tape position where recording ends, and there is no need to rewind to the beginning of the tape each time.

By exchanging tape cassettes 11 and repeating recording, recorded data (tape numbers and recorded contents) for a plurality of tape cassettes 11 will be registered as a library in the IC card 2a. IC card 2a
An example of data registered in is shown in FIG.

[ii] When the tape cassette 11 for rewriting recorded data is loaded into the video deck, the software 4 is started, and the CPU 3 performs the following steps in the same manner as described above.
The tape cassette 1 read from the number sticker 10
The tape number 1 is read and stored in the working memory 5. Then, the IC card 2a is searched based on this tape number, and all recorded data corresponding to the tape number is read out from the IC card 2a and stored in the working memory 5. Next, the CPU 3 searches the recorded data (tape number and recorded content) stored in the working memory 5 in the order of the recorded tape points, and displays it on-screen on the CRT 12 via the display controller 6. An example of this on-screen display is shown in Figure 5 (a
) and (b).

(a) is the case where the tape number is rooolJ, (b)
) is the case where the tape number is ro OO3J.

In the above-described on-screen display operation, when the recording content data includes a recording title, the CPU 3 estimates the recording time from the recording start time and recording end time and displays this on-screen, while the recording channel is not displayed. Greet. Furthermore, when the recording title is not included, the recording start time, recording end time, and recording channel are displayed on-screen (see ■ in Figure (b)). Furthermore, the CPU 3 determines whether there is an unused portion on the tape, and if there is, the CPU 3 determines the tape point at the beginning of the unused portion and the time corresponding to the recording mode and displays it on-screen ([ff1( b) ■.

■Reference).

(a) In the case of scheduled recording The user inputs data necessary for scheduled recording using the input device 9 while referring to the on-screen display. That is, input the recording start time, recording end time, recording channel, recording date, recording mode, and recording title. However, it is not necessary to input the recording title. The CPU 3 stores input or set data in the working memory 5.

The user then specifies the tape point at which recording should begin. The method for specifying this recording tape point is as follows:
There are three methods below, choose one of them.

1) Similar to the current method, the user fast forwards or rewinds the tape and starts recording from any tape point. In this case, the user refers to the content displayed on-screen on the CRT 12. Of course, you can also specify while checking the playback content of the tape.

When the user specifies a recording tape point, the CPU 3 inputs the designated recording tape point from the tape point sensor 7b and stores it in the working memory 5.

Next, the CPU 3 calculates the recordable time from the recording tape point to the recording tape point in the next one or more recorded programs and the recordable time until the tape end, and calculates the recordable time from the recording tape point to the recording tape point in one or more recorded programs that will come next, and calculates the recordable time until the tape end. A warning will be issued if available time is insufficient. However, scheduled programs such as recording start time that have already been stored in the working memory 5 are not canceled. When a warning is issued, the user will select a new recording tape point, either on the same tape or by swapping tapes.

2) This is a method of specifying a recording tape point by mainly referring to the recording time of the contents displayed on-screen on the CRT 12. In this case, the cursor 13 is moved to the on-screen display of the CRT 12 by operating the input device 9.
, and then press the specified key on the input device 9. Figure 5 (a)
In the example, the cursor 13 is placed on the program display marked ■. This is because the recording time of the reserved recording is within 30 minutes, and the already recorded program (2) may be deleted by the new recording. In this case, when the specified key is pressed, the CPU 3 sets r50 as the recording tape point.
Determine 0j and store it in working memory 5. When the recording time of the reserved recording is 1 hour and 20 minutes, for example, the cursor 13 is sequentially placed on the program displays ``■'' and ``■'' and the designated key is pressed.

In this case, the CPU 3 stores IQ OOJ as a recording tape point and r500J as data for erasing recorded content in the working memory 5, respectively. Deletion of recorded content will be described later.

3) A method of directly inputting the recording tape point by operating the ten keys on the input device 9. For example, if the recording time for scheduled recording is 30 minutes, you may want to delete the last 30 minutes of a recorded program that has a recording time of 1 hour and use that part for scheduled recording. It is something that is done on a regular basis. Alternatively, when making scheduled recordings using a raw tape, this is done when it is desired to record the program to be recorded first at a position later than the program to be recorded later due to the arrangement of the tape. Of course, refer to the on-screen display. In the case of (a) in FIG. 5, the tape point "250" is input, and the CPU 3 inputs r250J as the recording tape point.
is stored in working memory 5. In this case as well, C.P.
U3 issues a warning as necessary, as described above.

When a recording tape point is designated by any of the above 1) to 3), the CPU 3 performs the following operations.

First, the tape position is adjusted to a designated recording tape point by controlling the tape drive system to fast forward or rewind the tape. However, in case l), this operation is omitted because the tape position has already been aligned with the recording tape point. In the case of 2), in addition to the method of searching for a recorded tape point corresponding to the beginning of a recorded program based on the tape point signal from the tape point sensor 7b, there is also a method of searching for a recorded tape point corresponding to the beginning of a recorded program based on the tape point signal from the tape point sensor 7b. In order to adjust the tape position to the recording tape point even if the tape has been recorded, a method is adopted in which the beginning of the recorded program is searched based on the header search signal from the control track read/write section 7c.

When the tape position matches the recording tape point, the CPU
Step 3 moves to scheduled recording mode. That is, recording starts when the recording start time comes and stops recording when the recording end time comes.

When recording is finished, the CPU 3 inputs the tape number and recording contents (recording tape point, recording title, recording start time, recording end time, recording date, recording channel, and standard/3x recording mode) stored in the working memory 5. ) is read out and transferred to the reader/writer 2b, and the IC
Register on card 2a. Note that when there is a program that has been erased due to new recording, the data registered in the IC card 2a regarding the erased program is erased.

(bl) When using normal recording, the user should refer to the on-screen display and
As in the case of scheduled recording of time t, the tape point at which recording should be started is specified using any of the methods 1) to 3). When specifying using the method 2), unlike scheduled recording, the recording time is not fixed, so the cursor 13 only needs to be placed on one program displayed on-screen. Note that, of course, no reservation program is set. The designated recording tape point is stored in the working memory 5. When a recording title is input, this is also stored in the working memory 5.

By manual operation or by control of CPU3,
When the tape position matches the designated recording tape point, the user presses the record key.

This starts recording, and the CPU 3 reads the recording start time, recording date, recording channel, and standard/3x recording mode and stores them in the working memory 5.

During recording, the CPU 3 checks the recordable time up to the recording tape point and the recordable time up to the end of the tape in one or more next recorded programs, and displays a warning message on-screen if the time is insufficient. .

When the stop key is pressed and recording ends, the CPU 3 temporarily stores the recording end time and then stores the tape number and recording tape point stored in the working memory 5.
The recording title, recording start time, recording date, recording channel, and standard 73x recording mode are read out and transferred to the reader/writer 2b along with the recording end time, and the IC card 2
Register to a. Incidentally, when there is a deleted program, the data registered in the IC card 2a regarding the deleted program is deleted.

[iii] For playback, when the tape cassette 11 is loaded into the video deck, the CP
L13 inputs the tape number of the tape cassette 11 read from the number sticker 10 and stores it in the working memory 5, and also inputs the tape number of the tape cassette 11 read from the number sticker 10 and stores it in the working memory 5.
The card 2a is searched, and all recorded data corresponding to the tape number is read from the IC card 2a and stored in the working memory 5. Next, the CPU 3 searches the data stored in the working memory 5 according to the order of recording tape points, and displays the data stored in the working memory 5 in the C through the display controller 6.
Display on-screen on RT12.

The user specifies the playback tape point using the input device 9 while referring to the on-screen display. There are three methods for specifying this, similar to those for scheduled recording.

By manual operation or by control of CPU3,
The tape position is matched to the specified playback tape point. Note that when specifying the playback tape point by manual fast-forwarding or rewinding, header search and zero return techniques are also used to accommodate programs recorded using conventional methods. When the tape position matches the playback tape point, the user presses the playback key. This starts playback.

When the next header is detected, or the playback time matches the recording time, or the tape end is reached, the CPU3
stops playback.

[1v] Recorded data (tape numbers and recorded contents) for a plurality of tape cassettes 11 are registered in the other library management IC cards 2a. Therefore, by inputting a tape number from the input device 9, recorded data for the tape cassette 11 corresponding to the tape number is read out and displayed on screen.

Such reading and display of recorded data can be performed even when the tape cassette 11 is not loaded into the video deck.

Then, you can efficiently create labels and organize tapes by referring to the recorded data displayed on-screen. It is also possible to search the IC card 2a to find a tape with an unused portion for a predetermined period of time. this is,
This is useful when you suddenly want to record a certain program. Also, based on the recording title and other recording contents, the IC card 2a
You can also search for the tape on which the program you want to watch is recorded. Furthermore, if a recording title is not registered or a recording title is registered by mistake, the recording title can be input or corrected later.

When the IC card 2a becomes saturated, it is replaced with a new IC card 2a. #! ! For the IC card 2a that has been combined, the recorded data is organized by tape number and transferred to another IC.
It is also possible to re-register the card.

Note that the tape number reading device 1 may include an IC memory instead of the IC card 2a and the reader/writer 2b.

<Effect of the invention> According to the present invention, the following effects are achieved.

Since the recorded data (tape number and recorded content) of the videotape is registered in a recorded content storage device independent of the videotape, recorded data can be registered and read without rewinding the tape. You can do it and it will be easier to use.

Furthermore, since the recorded data of a plurality of video tapes can be registered in the recorded content storage device in its entirety and the recorded data can be read out and displayed, library management can be easily performed.
