Abstract

PURPOSE:To store a large amount of composite information on an inexpensive recording medium such as a cassette tape by registering and controlling characters and pictures, screen by screen, in the form of digital information and controlling sound information while adding it to each screen in the form of analog information. CONSTITUTION:Tape contents are classified roughly by a tape directory part 30 containing control information on each document, storage parts 40-1... for document contents, and blank parts 50-1... for preliminary tape running between documents. The overall length of a tape is divided into several and counter values are recorded and used as control information for starting and stopping the tape; and a blank area 60 is further provided. For example, screen information is stored in a random access storage area such as an IC memory and only in a sound information area, sound selection and reproduction are repeated synchronously with the screen. Consequently, a relatively large amount of composite information is stored on an inexpensive recording medium such as a cassette tape.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for easily storing and recording a large amount of composite information in which different types of information such as text, images, and audio are mixed in an information communication device.

Currently, complex information is generally handled by separate devices such as telephones (voice), facsimile machines (images), and data terminals (characters, symbols, etc.).

A prototype device was also created to electrically store images, audio, etc. as files along with character codes.

Will there be a lot of experimental presentations? However, both use expensive recording media such as hard disks and MT devices, or compress information.

The equipment has an expensive configuration and does not have the form of a communication device that can easily handle complex information without spending a huge amount of money on high-speed processing.

There are devices that store and manage character codes as well as images, audio, etc. as digital binary information on floppy disks, which are often used as relatively inexpensive recording media. The amount of information that has been digitized is enormous, and even an 8-inch double-sided double-density floppy disk (1 MB capacity) can store color image information on two or three television screens, or audio information on three to four minutes. It can only store information and cannot be used as an information communication device. Also, images and audio can be stored as analog signals on a floppy disk J: iv
There are also attempts to incorporate 8 (experimental &r) -1
At this time, in order to accommodate a large amount of analog signals as well as digital information such as character codes, the rotation speed of the f[hubbitisf] should be increased from 2000 to 3000 r, I]-m to 20 to 30 r, p, m. It is necessary to stably control the floppy disk drive control system within a range of

This invention uses an inexpensive magnetic recording medium that employs a sequential access method such as IT tape, which is commercially available as an audio equipment component, as a storage file for composite information, and converts character and image information into digital data. The present invention also relates to a method for easily storing and recording audio information as 7-analog data, and its purpose is to realize a complex information device that is inexpensive and easy to operate.The present invention will be explained below with reference to the drawings.

FIG. 1 shows an example of an object to which the present invention is applied, which includes a composite information control unit 11, a keyboard 121 for inputting characters and symbols, a VTR 13 as an image input device, and a microphone 14° screen as a voice input device. T as a display device

The same applies to other symbols.

Hereinafter, a cassette tape will be used as a recording medium with a sequential access structure, and a file organization method and management method for a composite information document configured as a VC will be described in detail.

Furthermore, the procedure for creating and reproducing a composite information document will be sequentially explained.

FIGS. 3(A) to 3(E) show examples of organization of composite information files constructed on the cassette tape 1B. The structure and recording method of the composite information file in FIG. 3 are as follows.

Figure 3 (A) File structure of the entire cassette tape 18
) shows the entire file structure of the cassette tape 1B, where the tape contents include a tape directory section 30 that stores management information for each document, and a document storage section 4°1+40-2 . ...... Blank area for tape run-up between each document 50-1.50-2
．．・・・・・・It is broadly classified into . Also, the total length of the tape is 10

is recorded and used as control information for starting/stopping the cassette tape 1B. 6o is an empty area.

In the example of FIG. 3(A), a fixed length tape directory section 30 (counter length 60) manages 30 documents.
) and the documents in the document storage section 40 are sequentially stored from the first side to the Nth side, and the tape force Kunta value is "89".
There is an empty area of 6° after “B”. In this case, the document storage area (B) and the tape directory area 3.
Figure 3 (B) shows the structure of the tape director m3.
This shows the details of a, and contains 1 to 30 document directories (fixed length) that contain document management information.
are arranged at equal intervals. The contents of the document directory are (1) the directory identification code at the beginning of the directory (
Fixed code) 31 (11) Document registration number (number from 1 to 30)
2 Ql+> Document start position (tape position counter) 33 (1■) Document end position (tape position counter) 34 (V> Number of document screens 35 (■1) Document title (registered arbitrarily by the user) 36, etc. In this example, the document storage section 40-2
Since is the second document directory (11)
is 2″, and (Il+) is 235″, and (1■
) is recorded as "392".

Therefore, all information necessary for management, such as document titles and storage locations, can be checked from the tape directory section 30, and speedy document selection operations are possible.

(C) Structure of document storage unit 40 Figure 3 (C)
1 shows the detailed structure of the document storage unit 40, which begins with a screen management table 41 that stores management information for each screen, and then screen information 42-1 consisting of text or image information. .......

42-M are stored sequentially. Furthermore, audio information 43, 44 added to each screen across blank spaces 45, 46 for the run-up of the tape is recorded as analog signals. In addition,■
indicates a digital information portion, and ■ indicates an analog information portion.

In the example of FIG. 3(C), M pieces of screen information 4 from 1 to M
2ゝ and audio information 43 added to the third and Mth screens
．． 44 storage status is shown.

By adopting such a structure, the digital information up to the screen information 42-M can be downloaded to a randomly accessible storage area such as an IC memory or a floppy disk, and only the audio information area can be read by accessing the cassette tape 1B. It is possible to select and play the selected audio repeatedly.

(D) Structure of the screen management table 41 FIG. 3(D) shows the detailed structure of the screen management table 41. The table has 20 fixed-length screen management programs from No. 1 to No. 20. 41. ~412o. In this case, the maximum number of screen pages for a document is 20 or less. Page information 41a1 screen (text/image) in the screen management block
In addition to information such as type information 41b and additional audio presence/absence information 41c, in the case of additional audio, warp start counter position information 41d and end counter position information 41e are entered.

In the case of the above example, the additional audio counter of the Mth screen information 42-M has a start position of "366" and an end position of "392". In this case, since the Mth screen information 42-M is the final screen of document 9, the end position is also the end position of the second document. Using this table information, you can switch text/image screen display control and select audio information that corresponds to the front screen.

Playback control is possible.

(E) Structure of screen information 42 FIG. 3 (E) shows screen 1) I/
This figure shows the structure of the information 42, in which 42-1 is a character double-sided information block and 42-M is an image screen information block. By setting both blocks to a fixed length, the access process to the cassette tape 18 can be simplified. In this example, the former is 2000 bytes and 2 per screen.
0 (10 characters (100 F1 characters in kanji)) (empty space has N u 11 code "00")
Just insert H++). The latter has 96 bytes and can accommodate color image information of about 4 (10 x 240 dot matrix).

Next, the procedure for creating and registering a composite information document on the cassette tape 1-8 will be specifically explained.

FIG. 4 shows the procedure for creating a composite information document. As will be described in detail below, screen information is first created, and then audio is added to each created screen to complete the creation work.

FIG. 4(A) shows the procedure for creating screen information, and the information is first sent to the Floppy desk 17 or +1. It is stored in a temporary storage medium that can be randomly accessed, such as an IC memory. The details are as follows. In addition, Fig. 3 (A) to (E
).

(1) First, read the document directory section from the cassette tape 1B, and then determine the document registration number 32 (Fig. 3 (B)), document start position information 33 (Fig. 3 (B)), etc. to be created. In addition, 1g of documentation is given to the operator! 36 (FIG. 3 (B)) from the keyboard 12, etc., and the document directory information is stored in the temporary storage medium (hereinafter referred to as floppy disk 17).
(Step 2 in FIG. 4(A)).

(2) Next, set the type of screen to be created to 5 (same step
).

(3) If it is a text screen, enter characters from the keyboard 12 etc. within a range that does not exceed the display size of the screen (Slap■)
.

(4) If it is an image screen, input a still image from the VTR 13 or the like (same step ■).

(5) - After creating the screen, set the screen management table 41 (FIG. 3 (D)) at the end of the document content (FIG. 3 (D)) and store it on the floppy disk 1 (
Figure 4 Step ■).

(6) The created screen information is also stored on the floppy disk IT (same step ■).

(7) Ask whether or not to continue creating the screen, and if so, (
Repeat steps 2) to (6) (same step ■).

(8) When the screen creation is complete, enter the document screen number information 35 (FIG. 3(B)) in the document directory (step 2 in FIG. 4(A)).

According to the above creation procedure, the screen information can be configured without having to be aware of the audio information, and since it is stored in a temporary storage medium that can be accessed randomly, it is possible to refer to previous page information during document creation. Modifications can also be easily made.

Figure 4 (B) shows the procedure for adding audio information.
The details are as follows.

(4) First, record the screen information from one temporary storage medium (in the case of FIG. 4(B), the floppy disk 17) and the information of the screen management table 41 (FIG. 3(D)) and the screen information 42.
is transferred to the cassette tape 1B (Fig. 4 (step ①, [phase] of B)).

(2) Next, the screen information completion position after transfer, that is, the start counter position information 41d for adding audio information (Fig. 3 (D))
(same step ■), write the corresponding position information in the 1-screen management table 41Vc, and record on the floppy disk 17VC (same step @).

(3) Display the double-sided information previously stored on the floppy disk 1T on the monitor. Of course, in the initial stage, voice input is performed using the first Crophone 14. Audio information can be recorded directly onto the cassette tape 18 as an analog signal. This state continues until the audio addition completion switch SWI+ is pressed (step 0).

(5) After the voice input is completed, the counter position of the cassette tape 1B is read and written to the screen management tag 41 in the floppy disk 17 as the end position information of the additional voice (step O).

(6) Until the sound/voice addition work is completed for all screens,
Repeat (2) to (5) above (same step [phase], @
).

For screens that do not require audio addition, the audio addition completion switch 5W11 may be pressed immediately without turning on the recording switch SW8.

(7) When the audio addition for the entire screen is completed, the document length in the document directory (the difference between the document start position information 33 and the document end position information 34 in Figure 3 (B) and the additional sound polish in the screen management block) cloth/no information 41c (FIG. 3(D)) and additional audio start/end counter position information 41d.

41e, the tape directory section 3° in the floppy disk 17 (Fig.
B), ) re-transfer the cassette tape 1BK for the screen management table 41 (Fig. 3 (C)) (Fig. 4 (B))
Step ■).

FIG. 5 shows the reproduction procedure of the composite information document recorded on the cassette tape 1B, and the details are as follows.

(Step 1) The tape directory section 30 (negative T3 diagram (B)) on the cassette tape 1B is displayed on the screen, such as the title 36 on the main memory MEM, and the document to be reproduced is selected (same steps ①, ①).

(3) The cassette tape 18 is fast-forwarded to the top position of the selected document, and all screen information is transferred to a randomly accessible storage medium such as the floppy disk 1T or IC memory (also in step 2).

The counter position of the cassette tape 1B after the screen information is transferred becomes the leading position of the audio information.

(4) Screen information 42 (
Figure 3 IC> ) is displayed on the monitor. In the initial stage, the screen starts from the first screen information 42-1 (also Step 2).

(5) After displaying on the screen monitor, play the additional audio from the cassette tape 18 (same step).

In this case, the analog signal from the cassette tape 18 is
The signal is directly amplified and reproduced by the speaker 16. After the audio ends, the end counter position ffi information recorded in the screen management block is used.

(6) The above (4L (5)) is repeated until the entire screen information, that is, the document is completed, but the screen update/return can be controlled by the operator's instructions (steps ① and ②).

The file organization method and file recording method when storing composite information on the cassette tape 18, as well as the composition procedure and reproduction procedure of the composite information have been described above.

In addition, in FIG. 3(C), it is also possible to store screen information and additional audio information for the screen as a pair K.

FIG. 6 shows an example of its storage. Here, 46 indicates a blank space for tape run-up. Other details are the same as in FIG. 3(C). In this case, it is necessary to add audio every time a screen is created. In addition, in Figure 4 (A), the screen information is
There is also a procedure to store directly onto the cassette tape 18 without storing it in a temporary storage medium such as a disk, but in this case, when writing information such as the number of screens to be registered and tape running force tank information after adding audio, etc. It is necessary to repeat rewinding 1, fast forwarding, etc. of the tape 18.

As explained in detail above, this invention allows a relatively large amount of composite information to be stored on a simple recording medium such as a cassette tape by treating an image of a character as digital information and audio as Bunalog information. There is an advantage.

(2) By registering and managing character information and image information for each screen, and by adding and managing audio information to each screen, screen type, presence or absence of additional audio, storage area Wt for additional audio , # screen management information can be configured with a fixed length, and there is an advantage that selection and playback control of screen information and selection and creation of 7-stage additional audio information on a cassette tape can be speedily performed.

(3) Registering a composite information document as a collection of one or more screens of screen information, and placing a fixed-length management information area at the beginning of the cassette tape in which counter positions indicating the start and end positions of the composite information document are written. This has the advantage that composite information can be selected document by document and reproduced quickly.
