Field of the Invention The present invention relates to a still image file system, and more particularly, to a still image file system in which a still image is filed together with other data in a large-capacity storage device for playback and use, and a playback device and a storage medium therefor. .

2. Description of the Related Art Several devices for storing and reproducing still images and sounds in a large-capacity storage device have been developed. In a conventional apparatus, still images and sounds are stored in a mass storage device in a pre-programmed order, and are reproduced in that order.

In a site where such a playback device is used, for example, in a program production site, the order and effects of playback are modified according to the situation when a still image is played back with sound or text and according to the user's request. It is often required to change the mutual relationship between pieces of information such as images, sounds, and characters. For example, it may be desirable to change the order of scenes, increase the speed of fade-out, or change the time at which the beginning of a series of sounds precedes image scene switching. The possibility of making these changes freely in the field is important not only for projecting photographic images, but also for the purpose of organically combining video, audio and text information to enhance the production effect. is there. Further, there is a case where it is desired to additionally record a new image or sound while watching the reproduced video or listening to the sound.

However, in the conventional apparatus, since the storage of information in the large-capacity storage device is fixed, it is not easy to change the reproduction condition in accordance with an instruction input by the operator.

DESCRIPTION OF THE EMBODIMENTS Next, an embodiment of a still image file system according to the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, a still image file system according to an embodiment of the present invention basically includes a floppy disk for randomly storing information or data of images, sounds, and / or characters.
10, which is transmitted to a reproducing apparatus 12 to store the information on an optical disk 14, while a procedure for reproducing the information is stored on a floppy 16, and the reproducing apparatus 12 reads the information from the optical disk 14 according to the procedure. Is read out and reproduced from the high-definition (high-definition) TV receiver 18 and the speaker 20. The data file floppy 10 may be different for each data type.

The image recorded on the floppy 10 as a data file includes, for example, a natural image obtained from a camera or a scanner 22, characters or codes generated by a processing system, or a binary image, and is in the form of a still image. . This recording is generally performed at a location separate from the playback device 12, for example, at a recording studio. Data file floppy 10 contains 1
A video signal representing a scene is recorded together with the scene name and the video signal mode. The name of the scene is the file name. One of the features of this embodiment is that the scene name is described in a natural language. In this embodiment, the video signal is recorded in one of the multi-screen mode, the fine mode, and the differential PCM (DPCM) type c (FIG. 3), and has a high-definition TV standard signal format.

Similarly, the voice is recorded from the voice input device 24 to the data file floppy 10. This sound is a series of sounds related to a still image recorded on the data file floppy 10, such as narration, background music, and the like. This recording is also performed, for example, in a sound studio by a recording studio or a processing system, and is generally performed on a different floppy disk at a place different from, for example, the recording of a video image. An audio signal representing a sequence of audio is recorded on the data file floppy 10 together with its file name and audio signal mode. This file name is also described in a natural language, and the audio signal is recorded in this embodiment in one of stereo, bilingual, and monaural type c (FIG. 3).

In this embodiment, characters related to a still image recorded on the data file floppy 10 such as a title,
Telops and / or descriptors are also stored in the data file floppy 10. The character information is created by a processing system such as a word processor 26 or a personal computer, and stored in the data file floppy 10. This character creation is also advantageously performed, for example, in a place different from the recording of video and audio, for example, and a different floppy is used. The descriptor is the copyright of the data in the data file 10,
It includes the date of production, producer, content memo, etc., and is advantageously used for searching the content of the data file 10. Each of these information is advantageously digitized and stored on the floppy 10.

The procedure file 16 is also created from the word processor 26. A procedure for reproducing data stored on the optical disk 14 from the data file floppy 10, that is, a procedure, is recorded in the procedure file floppy 16. This procedure is editing information that defines the reproduction conditions of the data file 10, such as information on the file name n (FIG. 4), related file information, switching time or timing t, and effect e. This defines the order, timing, and special effects in the reproduction of the file data.

The associated file information includes, for example, the mode of the video or audio signal, and the version v when the image or audio with the same file name n is revised. The switching time t defines the time during which one scene or a series of sounds continues. The information on the effect e defines various special effects such as video effects such as cut, scroll, wipe, and dissolve, and an effect delay that delays the start of video with respect to the start of audio.

These procedures are input in a natural language using, for example, alphanumeric characters and / or kanji. This is converted into a control signal by hardware of the system control unit 32, data is read from the optical disk 14, and a specified effect operation is performed at a specified timing.

In general, the procedure file 16 is often created on a different floppy disk at a place different from the place where the data file 10 is created or played by the playback device 12. The procedure file 16 is created not only by the word processor 26 but also by a processing system such as a personal computer. Thus, in this embodiment,
Individual data file floppies 10 and procedure file floppies 16 are created independently of each other, and they are ultimately taken to the location of the playback device 12 where data and procedures are randomly stored on the optical disc 14 of the playback device 12. You. That is, the data file 10 and the procedure file 16 are recorded irrespective of the order of recording information having different objects, different properties, and different contents, and physical recording locations. This is the image,
The telop, font, descriptor, procedure, and audio files are kept independent and can be edited by any combination of them.

The playback device 12 has a floppy disk device 28, on which a data file floppy 10 and / or a procedure file floppy 16 are set and from which data and procedures are read. The read data and procedure are stored on the optical disc 14.

The optical disk 14 is a main file storage device of the playback device 12, and a write-once optical disk is advantageously used. One of the features of this embodiment is that the data file floppy 10
In addition, all of the video, audio, characters, and procedures are randomly input to the optical disk 14 from the procedure file floppy 16 and are randomly and additionally stored therein. However, the data stored in this manner is read out to the memory 30 in accordance with the reproduction conditions such as the order, time and effect specified in the procedure, and finally reproduced from the high-definition TV receiver 18 and the speaker 20. Is done.

Although the storage capacity of the optical disk 14 is constant, the ratio of images, sounds, characters, procedures, and the like stored in the optical disk 14 depends on mutual trade-offs and is not constant. The image data has a fixed data amount of one field or frame, and image data of one scene is read from the optical disk 14 into the memory 30 at one time. However, the length of the voice data differs depending on the situation of recording or voice synthesis. Therefore, when all the sounds stored in the memory 30 are reproduced, the next sound is read from the optical disk 14 into the memory 30. In this embodiment, a series of audio data is stored in a series of storage locations on the optical disc 14.

The playback device 12 has a system control unit 32 and the optical disc 14
The storage of data and procedures in, and the reproduction and editing of data are controlled by the system control unit 32. The system control unit 32 is a logic circuit network whose operation is managed by the operating system,
For example, a processing system such as a microprocessor is advantageously applied.

Normally, the image is reproduced together with the sound. To this, reproduction of characters is added as necessary, or characters and voice are reproduced. In a broad sense, the term "image" also includes characters. The playback mode of the apparatus 12 has four types of fully automatic playback, sequential playback, conversational playback, and designated playback. The full-automatic playback mode is a mode in which playback is performed in a pre-programmed order and projection length. The sequential playback mode includes a manual trigger mode and an audio trigger mode. In the former, the reproduction is performed in a pre-programmed order, but the screen is changed by a manual operation instruction.
In this case, the images can be projected in the reverse order. The latter is different from the fully automatic reproduction mode and the manual reproduction mode in that the image is changed when the audio file being reproduced ends.

The interactive reproduction mode is a mode in which a question / answer selection option or a multi-screen is displayed on the video display device 18, and by answering this, target information is reproduced. In the nominated playback mode, there are a file name key input playback mode for designating a file name, and a cursor selection playback mode for designating a playback image by a cursor operation on a multi-screen. The apparatus of this embodiment includes a remote control unit 34, which can be used to input an operator's instruction.

In the present embodiment, a system batch for automatically operating a plurality of programs by storing a plurality of procedure files 16 on the optical disc 14 and selectively running the procedure files according to a desired program can be performed. This system batch is also stored in the system controller 32.
Is controlled by

Another characteristic of the present embodiment is that the user can modify the reproduction conditions such as the order, time and effect while viewing the images and sounds reproduced by the reproduction device 12. Initially, the playback procedure is recorded in the procedure file floppy 16. This is a provisional one created by a word processor 26 or the like. However, when the sound or image recorded in the data file floppy 10 is actually monitored by the procedure recorded in the procedure file floppy 16, it is often desired to delicately correct the reproduction conditions. Therefore, the reproducing apparatus 12 of the present embodiment operates the keyboard 50 (FIG. 2) of the system control unit 32 to change the order of reproduction, time, effects, and other procedures, and thereafter performs reproduction under the changed reproduction conditions. Has an editing function. The finally determined procedure file 16 may be recorded on the optical disc 14.

As described above, according to the present embodiment, not only a picture of a photograph is projected, but also other information such as a sound and a character can be organically combined with the image to enhance a staging effect. These connections can be freely changed by the user on site. In addition, since a write-once optical disk is used for the main storage medium, information can be additionally recorded even at the site, and it is also suitable for applications where contents are frequently added or updated.

In the specific configuration of the reproducing apparatus 12 shown in FIG. 2, when the data floppy disk 10 is set in the floppy disk device 28, the data such as images, sounds or characters stored therein is read out to the optical disk 14, and Is stored. With these data, images, sounds or characters are randomly written on the optical disk 14 in accordance with the floppy disk 10 set in the floppy disk device 28, thereby forming a data file 52. At this time, the system control unit 32 determines which address a of the optical disc 14, that is, a directory indicating which data is stored in the track and sector.
54 is created and written on the optical disk 14. Therefore, the directory 54 forms a table for designating the file name n, data type c and version v of the data of the data file 52 corresponding to the address of the data file storage area of the optical disk 14.

The procedure file recorded on the floppy 16 is also read by the floppy disk device 28. This is read out each time it is used in this embodiment. Alternatively, for example, in the case of a procedure that has been finally determined, the procedure may be such that the optical disk 14 is first read from the floppy disk 16 and accessed when used. The record format of the procedure file used inside the playback device 12 includes a header record 100 illustrated in FIG. 3 and scene data records 120 and 140 illustrated in FIGS. 4 and 5.

The header record 100 includes six valid fields of a file type 102, a repetition count (RECUR) 104, a program name 106, the number of scenes 108, a time 110, and a CS audio 112. The scene number 114 is set to a predetermined value indicating a header, for example, “0”. The file type 102 defines a playback mode, and specifies one of fully automatic playback, sequential playback, and interactive playback. The number of repetitions 104 defines the number of repetitions of full-automatic reproduction. The program name 106 uses alphanumeric characters and kanji in this embodiment, and defines the name of a program that performs a series of images, sounds, and characters. The number of scenes 108 defines the number of subsequent scenes included in the program, and the length of the program is defined by time 110. In the case of the fully automatic playback mode, the type c and the version v of the audio signal are further defined by the CS audio 112.

The scene data record 120 shown in FIG. 4 is used in the case of the fully automatic reproduction mode, and the scene data record 140 shown in FIG. 5 is used in the case of the sequential reproduction mode. For example, at the beginning of a fully automatic playback scene data record 120 is a scene number field 122, which defines the sequence of a series of scenes in a particular program. In the scene data record 120 for fully automatic reproduction, a scene number 122 is followed by fields of a video file full path name 124, related file information 126, switching time 128, delay effect 130, and special effect 132.

The video file full path name 124 defines the file name n, data type c, and version v. For the file name n, alphanumeric characters and kanji are used in the present embodiment.
Natural language notation such as "JISAN" is used. The associated file information 126 defines the type c of the video signal and the version v of the telop, font, audio, and descriptor. For example, "FUJISAN.N00" is the title "FUJISAN.
AN "is defined as the image data of the first version of the normal mode. These file name n, type c, and version v function as an index for specifying the data of the data file 10.

The switching time 128 defines the duration of the fully automatic playback mode in minutes (M), seconds (S), and TV frames (F).
For the effect e, the effect delay field 130 and the special effect field 132 can be used. The type of effect, for example, a video effect such as cut, scroll, wipe, dissolve, etc., is specified by an effect number, and a character layer, scroll control, character color control, etc. can be specified. Also,
For example, when a delay time is set separately from screen switching at the time of scrolling, the delay time is specified by the effect delay 130.

In the scene data code 140 in the sequential playback mode, an audio trigger delay time field 142 is defined instead of the switching time 128. This specifies the time to delay the start of reproduction of the next image from the end of the audio file.

Returning to FIG. 2, a floppy disk 16 or an optical disk
In the procedure file 72 stored in 14, the details of the file name n, data type c, version v, time t, and effect e for a certain program are specified in the above-described manner. On the other hand, the optical disk 14 randomly stores image data, audio data, and character data. For example, when reproducing a certain program, the procedure file floppy 16 of the program is loaded into the floppy disk device 28, and the program name 106 is specified from the keyboard 50 to input a reproduction instruction. In response to this, the system control unit 32 supplies a stepping pulse 56 from the internal clock to the address counter 58.

The address counter 58 stores the internal procedure file 72
Is a counter for generating an address for designating the storage position of, and increments in response to the stepping pulse 56. From the procedure file 72, the scene data record is stored from the sequential storage position according to the increment of the address counter 58.
120 or 140 is read. The data type c, effect e and time t are stored in the switching circuit 62, the memory 64 and the memory 66, respectively, and the file name n, data type c and version v are stored in the matching circuit 68.

The system control unit 32 also advances the address counter 70 of the directory 54, and sequentially reads the file name n, data type c, and version v stored in the directory 54. The matching circuit 68 compares the file name n, the data type c, and the version v sequentially read from the directory 54 with those extracted from the procedure file 72. Until they match, the address counter 70 of the directory 54 continues to advance. If they match, the address a currently being read from the procedure file 72 is held in the register 74, which is set in the address register 76 of the data file 52. So the data file
From 52, the data at the address designated by the address register 76, that is, image, sound or character data, is read to its output 78.

The memory 30 includes a character memory bank CM and a video memory bank.
Each storage area of VM and voice memory bank AM is 2
A system is prepared and writing is performed by alternately switching with switches 84, 86 and 88, respectively. Writing from the data file 52 to the memory 30 is selected by the switch 80 in accordance with the data type c. The switching circuit 62 in which the data type c has been set from the internal procedure file 72 earlier sets the connection position of the switch 80 according to the data type c. Therefore, when data is read from the data file 52, the data is stored in the bank of the memory 30 corresponding to the type c.

The image data is written to the video memory bank VM1 or VM2. Video memory bank VM1 or VM2 is 1
It has storage capacity for frames. The image data written in these video memories is read out to the video circuit 204 in real time, that is, at a TV signal rate. The video circuit 204 converts the image data to a corresponding analog signal, and outputs the analog signal to the receiver 18 with a necessary effect. The effect given by the video circuit 204 is indicated by expanding the effect information e read from the procedure file 72 to the memory 64 by the decoder 98. The video circuit 204 applies a video effect such as cut, scroll, wipe, or dissolve to the video signal, and outputs the video signal to the receiver 18.

Video circuit 204 also includes a DPCM decoder (not shown), which expands band-compressed image data. DPCM
Since the mode is recorded in the type c of the procedure file 72, when it is read out by the switching circuit 62,
62 activates the DPCM decoder of the video circuit 204. As a result, the video circuit 204 decompresses the DPCM-encoded video signal. In the fine mode, the DPCM decoder is not operated.

For example, while the image data of one scene is being reproduced from one area, for example, the bank VM1, the image data of the next scene is read from the data file 52 and written to the other bank VM2. Image memory banks VM1 and VM
A switch 86 is arranged on the write input side of the switch 2, and switches its connection position alternately in response to the switching circuit 206. Reading of the image data from the data file 52 and writing to the memory bank VM2 are performed in the same manner as described above. That is, the system control unit 32 increments the address counter 58 of the procedure file 72 and reads out the procedure data of the next scene. Thus, the image data of the scenes in the order specified by the procedure file 72 is transferred from the data file 52 to the image memory VM2.
Or, it is alternately written to VM1.

Similarly, writing and reading of character data to and from character memory banks CM1 and CM2 are performed. The video circuit 204 superimposes the character read from the character memory bank CM1 or CM2 on the image read from the image memory bank VM1 or VM2, and outputs the image to the receiver 18. As a result, reproduction of a telop, font, or descriptor is performed.

By the way, the image effect which needs to change with time is determined by the matching circuit 94.
It is executed according to the instruction from. The timing of the effect is monitored by the coincidence circuit 94. The present apparatus 12 includes a timer 96 for defining an internal time, and a coincidence circuit 94 monitors the time when the time generated by the timer 96 coincides with the time t set in the memory 66 from the procedure file 72. If they match, match circuit 94 activates decoder 98. The switching circuit 206 is connected to the decoder 98 as shown. The circuit 206 determines whether the reproduced image on the monitor 18 may be switched and whether the special effect has ended according to the effect specified by the decoder 98.
Control 86. As described above, the special effect is generated by the video circuit 204 and the switching of the switches 84 and 86 based on the effect information e and the time information t of the procedure file 72.

As described above, the image data has a fixed data amount, and the image data of one scene is read into the image memory bank VM1 or VM2 at a time. However, when the sound stored in one area, for example, the bank AM1 is completely reproduced, the next sound data is written into the sound data.
A switch 90 is arranged at the read output of the audio memory banks AM1 and AM2, and switches the connection alternately while taking the connection opposite to the switch 88 on the write side. Thus, while the audio data is being read into one audio memory bank AM1, the audio data stored therein is read from the other audio memory bank AM2. This is converted into an analog signal by the audio circuit 92 and output to the speaker 20, so that the continuity of the audio is maintained.

Switches 88 and 90 in voice memory banks AM1 and AM2
Is controlled by the counter 200. Since the amount of audio data stored in the audio memory banks AM1 and AM2 is constant, the time of audio reproduced from it is constant. The counter 200 monitors the time limit. When a predetermined time period is reached, the counter 200 switches the switch 90 and activates the interrupt circuit 202. The interrupt circuit 202 then increments the address register 76 by the adding circuit 76a of the address register 76. At the same time, the interrupt circuit 202 switches the write-side switch 88 of the audio memories AM1 and AM2 to interrupt the data file 52 for reading. This is because audio data reproduction requires real-time processing, so that audio data reading should be given priority over image data reading. In this way, a series of voices are successively read from the data file 52 and stored in the voice storage area AM.
The sound is continuously reproduced from the speaker 20 using 1 and AM2 alternately.

For example, in the case of the fully automatic reproduction mode, the coincidence circuit 94 also monitors the switching timing of the projection of the image of one scene. When the time of the timer 96 coincides with the time t set in the memory 66 from the procedure file 72, the coincidence circuit 94 activates the decoder 98 to give an effect instruction to the video circuit 204. And 86 are switched to reproduce the next scene. The switching of the playback image and audio is performed in the procedure file of the specific program.
It continues until all scenes set to 72 end. When the automatic reproduction is completed, the system returns to the initial state.

In the manual trigger mode of the sequential playback mode, the system control unit 32 increments or decrements the address counter 58 of the procedure file 72 in response to a manual operation instruction from the remote control unit 34 or the keyboard 50. As a result, the screen is changed in the normal or reverse order according to the manual operation instruction, and the reproduction is performed in the programmed order. In the audio trigger mode, the system control unit 32 executes image conversion in response to the occurrence of an interrupt by the interrupt circuit 202.

In another playback mode, for example, in the interactive playback mode, the system control unit 32 displays a question / answer selection or a multi-screen on the video monitor device 18 and answers it from the keyboard 50. Similarly, target information is read from the data file 52 and reproduced.

In the present embodiment, editing can be performed by operating the keyboard 50 of the system control unit 32. For this editing function, the reproducing apparatus 12 has an attribute (A) register 210. FIG. 6 shows the relevant parts. A register 210
Is the item or attribute of the procedure to be modified, ie, name n, data type c, version v, time t, and effect e.
Is a register for storing the data of the procedure file 72 and rewriting the corresponding item of the procedure file 72. Data and instructions for editing are input from the keyboard 50 in a natural language. The input editing data or instruction is transmitted to the code conversion unit 21.
It is converted into a machine code in 2 and input to the system control unit 32.

Editing is performed by changing the procedure data of the procedure file 72. After instructing editing by operating the keyboard 50, one of the attributes of the procedure to be modified is specified. This designation is converted into a corresponding code by the code conversion unit 212, and the system control unit 3
Entered in 2. Therefore, the system control unit 32 closes the switch 214 corresponding to the designated file attribute. Next, when the data of the attribute is input from the keyboard 50, the data is similarly converted into a machine code by the code conversion unit 212 and stored in the storage location of the attribute in the A register 210 through the corresponding switch 214. Thus, the A register 210
Is set with data of a desired attribute. Therefore, when an execution instruction is input from the keyboard 50, the system control unit 32
Sets the associated address in the address counter 58 of the procedure file 72 and writes the contents of the A register 210 to that location in the procedure file 72.

In the present apparatus 12, for example, a new procedure file 72 can be created using this editing function. In this case also, the procedure file 72
Is created, but the version v is set to “0”. The switching time t is set to a rough value according to the scenario.

Some examples of editing will be described. For example, when the scene switching time is changed, the intention of the scenario creator is not satisfied even if the program is actually played back according to the procedure file 72 already created, and it is desired to correct the scenario. This is effectively used when it is desired to adjust the timing with high accuracy. Referring to FIG. 2, images and sounds are reproduced by the above-described operation, and during that time, the timer 96 is counting the internal time as described above.
When the operator operates the switch time designation switch (not shown) of the keyboard 50 at the time of switching the image or the sound, the system control unit 32 closes the switch 216 in response thereto. As a result, the time counted by the timer 96 is set in the switching time field t of the A register 210. A
The contents of the register 210 were later written to the procedure file 72, thus modifying the playback scene transition time t of the procedure file 72.

When the operator inputs the instruction from the keyboard 50 when the procedure file 72 with the changed switching time t is tried, the system control unit 32 decrements the address counter 58. Then, when the operator instructs the reproduction from the keyboard 50, the reproduction operation is performed from the scene immediately before the switching, and it is possible to confirm whether the switching of the image or the sound is set at the timing according to the scenario. Of course,
The system may be initialized and an instruction may be issued to start playback from the beginning of the program. The procedure file 72 in which the playback conditions are finally determined is stored in an instruction key (not shown) of the keyboard 50.
Is written on the optical disc 14 for later use.

When revising specific data of the data file 52 recorded on the optical disc 14, for example, an image of a certain scene, first, the scanner 22 records new image data on the data file floppy 10. At this time, the file name n uses the same name as the old image data file to be revised. Thus, the data file floppy 10 on which the new image data is recorded is set in the floppy disk device 28.

When a read instruction for the data file floppy 10 is input from the keyboard 50, the system control unit 32 reads the data file from the floppy 10 in response to the instruction, writes the data file to a free area of the optical disk 14, and writes the address a of the free area. Set in the A register 210.

At the same time, the system control unit 32 reads the header record of the data file floppy 10. As shown in FIG. 7, the header record includes the file name n, data type c, version v, and address a on the floppy 10 of the data. Therefore, the system control unit 32 sequentially reads the directory data from the directory 54 of the optical disc 14. The file name n and the data type c of the directory data are taken into the matching circuit 68 and compared with the corresponding one of the header records read from the floppy 10. System control until the former matches the latter
32 increments the address register 76 and reads the directory data n and c from the sequential storage locations of the directory 54.

If the two match, the matching circuit 68 loads the header record of the data falfloppy 10 into the A register 210. The contents n, c, v, a of the A register 210 are then written to that location in the directory 54. At this time, the old directory data read from the directory 54 is written into the directory 54 after the value of the version field v is incremented. Therefore, from now on, the new data will be used as version "0" and the procedure file
Copy this new data file to the optical disk without updating 72
Available from 14.

In the present embodiment, when audio data is input from the floppy disk device 28 while a certain scene is being reproduced, the audio data is added to the file name n of the image data being reproduced and is stored in the data file 52 of the optical disk 14. Written. For example, first, voice data is recorded on the floppy 10 by the voice input device 24. This audio data need not have the file name n.

Next, as shown in FIG. 8, the audio data file floppy disk 10 is set in the floppy disk device 28. Then, the user operates the keyboard 50 to instruct reproduction of a desired scene to which new audio data is to be added. Therefore, the system control unit 32 searches for the file name n of the directory 54 by the address counter 70 as described above, reads out image data from the optical disc 14, and performs a reproducing operation. At this time, the directory of the image data being reproduced is read from the directory 54, and its file name n
Are held in the A register 210.

When an audio recording instruction is input from the keyboard 50, the system control unit 32 reads the audio data file recorded on the floppy 10 in response to the instruction, and writes the audio data file in the free storage area of the optical disk 14. The address a of the empty area is set in the A register 210. Next, the system control unit 32 sets the type c of the A register 210 to “voice”.
And the version v is set to "0", and the contents n, c, v, and a of the A register 210 are written to the directory 54. Thus, the audio data written on the optical disc 14 is
Thereafter, the data can be used as audio data of the file name n and the version v specified by the directory data of the directory 54.

Such automatic assignment of the file name n is also applied to data of other types other than voice. For example, when character data is input from the floppy disk device 28 during reproduction of image data, the character data is written to the optical disk 14 with the same file name as the image data being reproduced in the same manner as described above.

Effect The present invention thus independently creates different types of data files, which are randomly stored on a mass storage medium. The playback conditions for these data files are created separately as a procedure independent of the data files. The data file is created at a production site suitable for the characteristics of each data such as images and sounds. Therefore, a large amount of information resources are effectively used. These data files are indexed by a common file name, and their reproduction is performed by the procedure file using this file name. Therefore, the degree of freedom in the configuration of the file is large, and the functional restrictions in the conventional device are reduced.

As described above, according to the present invention, it is possible to increase the extension effect by not only displaying a photographic image but also organically combining other information such as voice and text. These connections can be freely changed by the user at the site, and if a write-once optical disc is used as the main storage medium, information can be additionally recorded even at the site, which is also suitable for an application example in which contents are frequently added or updated. .
