Description

TECHNICAL FIELD The present invention relates to a still image file system, and more particularly to a still image file editing device for editing the state in which a still image is played back from a large capacity storage device in which the still image is filed together with other data. .

BACKGROUND ART Several devices have been developed for storing still images and audio in a mass storage device and reproducing them. In conventional devices, still images and audio are stored in a mass storage device in a preprogrammed order and are played back in that order.

In the field where such playback devices are used, for example in the field of program production, the playback order and effects may be modified depending on the situation when playing still images together with audio and text, and the user's requests. It is often necessary to change the relationship between information such as images, sounds, and text. For example, you may want to change the order of the scenes, speed up the fade-out, or change the amount of time the beginning of a sequence of audio precedes a video scene change. The possibility to freely make these changes on-site is important for the purpose of not only projecting photographic images but also organically combining video, audio, and text information to increase production effects. be. In addition, you may want to additionally record new images and audio while watching the video or listening to the audio that has been played back.

However, in conventional devices, since information is stored in a large capacity storage device in a fixed manner, it is not easy to change playback conditions in response to input instructions from an operator.

Purpose: In view of these demands, the present invention is a stationary system that eliminates the functional limitations of conventional devices, instantly responds to the requirements of single-program productions, and makes it possible to effectively utilize a large amount of information resources. The purpose of this invention is to provide an image file editing device.

DISCLOSURE OF THE INVENTION A still image file editing device according to the present invention includes a file storage means for storing a still image together with an index in a first storage medium and storing audio together with an index in the first storage medium, and a rewritable second storage. a reproduction means for associating still images and sounds stored in a first storage medium with an index and reproducing them as visible images and audible sounds, respectively, according to a procedure stored in the medium; and a manual operation means for inputting instructions; and editing means for modifying the procedure stored in the second storage medium in relation to the index based on the input instruction, and storing the modified procedure in the second storage medium.

According to the present invention, in the above-mentioned editing device, the manual operating means inputs instructions in a human language, and the editing means defines a procedure for the input instructions. DESCRIPTION Next, embodiments of the still image file system according to the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, the still image file system according to the embodiment of the present invention basically stores image, audio, and/or character information or data randomly on a floppy disk.
0, and the playback device 12 stores the information on the optical disk 14. On the other hand, the procedure for playing back the information is stored in the floppy 1B, and the playback device 12 reads the information from the optical disk 14 according to this procedure. is read out and reproduced by the TV receiver 18 and speaker 20 in high quality (high definition). Separate data file floppies 10 may be used for each type of data.

The image recorded on the floppy disk as a data file may be, for example, a natural image obtained from a camera or scanner 22, a character or code generated by a processing system, or a 22
Contains value images and is in the form of still images. This recording is generally performed at a location separate from the playback device 12, for example in a recording studio. In the data file floppy 10, a video signal representing one scene is recorded together with the name of the scene and the video signal mode. The scene name becomes the file name. One of the characteristics of this example is that
This scene name may be written in natural language. Further, in this embodiment, the video signal is recorded in Type C (FIG. 3), which is one of multi-screen mode, fine mode, and differential PCM (DPCM), and has a high-definition TV standard signal format.

Similarly, audio is recorded from the audio input device 24 to the data file floppy 10. This audio is a series of sounds, such as narration, background music, etc., associated with the still images recorded on the data file floppy IO.

This recording is likewise done, for example, in a recording studio or by way of audio synthesis by a processing system, and typically represents a sequence of audio, often on a separate floppy in a separate location from, for example, the video recording. The audio signal is recorded in the data file floppy 10 along with its file name and audio signal mode. This file name is also written in natural language, and in this example, the audio signal is one of stereo, bilingual, and monaural type C (tertiary type C).
(Figure).

In this embodiment, characters related to still images recorded on the data file floppy 10, such as titles,
A telop and/or disc libter etc. are also stored in the data file floppy IO. These character information are created by a processing system such as a word processor 26 or a personal computer, and stored in the data file floppy 10. This writing is also advantageously often carried out in a separate location from, for example, video and audio recording, and a separate floppy disk is used. Note that the disc libter includes information such as the copyright, production date, producer, content memo, etc. of the data in the data file 10, and is also advantageously used for searching the content of the data file 10.

Each of these pieces of information is advantageously digitized and stored on floppy disk 10.

A procedure file 18 is also created from the word processor 26. The procedure file floppy 16 contains
A procedure for reproducing data stored on the optical disk 14 from the data file floppy 10 is recorded. This procedure defines the playback conditions for the data file 10, such as the file name n (FIG. 4), related file information, switching time or timing t, and information regarding the effect e. This defines the order, timing, and special effects in the playback of file data.

The related file information includes, for example, the mode of the video or audio signal, the version V when the image or audio with the same file name n is revised, and the switching time t defines the time that one scene or a series of audio continues. . Information regarding effect e is
For example, various special effects are defined, such as video effects such as cuts, scrolls, wipes, and dissolves, and delay effects that delay the start of the video relative to the start of the audio.

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

The procedure file 16 is also generally created on a separate floppy disk at a different location from the data file 10 creation and playback by the playback device 12. Also created by the processing system. As described above, in this embodiment, each data file floppy 10 and procedure file floppy 16 are created independently of each other, and they are finally brought to the playback device 12 and written on the optical disc 14 of the playback device 12. Data and procedures are stored randomly. In other words, the data file 10 and the procedure file 16 record information of different objects, different properties, and different contents without regard to the order or physical recording location. This maintains the independence of image, subtitle, font, descriptor, procedure, and audio files, and allows editing by freely combining them.

The playback device 12 has a floppy disk drive 2, which is used to read data and procedures from the data file floppy 10 and/or procedure file floppy 1G, and the read data and procedures are It is stored on the disk 14.

The optical disk 14 is the main file storage device of the playback device 12, and a write-once optical disk is advantageously used.One of the characteristics of this embodiment is that the data file floppy 10 and the procedure file floppy 16 can be used to store videos, videos, etc. Both the single voice character and the pronunciation are randomly input to the optical disc 14 and are randomly stored on the optical disc 14 in an additional manner. However, data stored randomly in this way is stored in the memory 3 according to playback conditions such as order, time and effects specified in the procedure.
0 and is finally reproduced from the high-definition TV receiver 18 and speaker 20.

Although the storage capacity of the optical disk 14 is constant, the ratio of images, sounds, characters, procedures, etc. stored on it depends on mutual trade-offs. The image data of one scene is read from the optical disk 14 into the memory 30 at a time. However, the audio data
The length varies depending on the recording or speech synthesis situation.

Therefore, when all the sounds stored in the memory 30 are played back, the next sound is read from the optical disc 14 into the memory 30. Note that 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 storage of data and procedures on the optical disc 14, and the playback 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 an operating system, and a processing system such as a microprocessor is advantageously applied.

Normally, images are played along with sound.

In addition to this, text playback may be added as needed, or text and audio may be played back. Note that in a broad sense, the term "image" also includes text. There are four types of playback modes of the device 12: fully automatic playback, sequential playback, conversational playback, and designated playback. The fully automatic playback mode is a mode in which the images are played back in a preprogrammed order and length of time. The sequential playback mode includes a manual trigger mode and an audio trigger mode. In the former, playback is performed in a preprogrammed order, but the screen changes are based on manual instructions. In that case, projection can be performed in the forward or reverse order. The latter differs from the fully automatic playback mode and the manual playback mode in that the image is switched when the audio file being played ends.

The interactive playback mode is a mode in which a question/answer option or a multi-screen is displayed on the video display device, and target information is played back by answering the screen. The designated playback mode includes a file name key manual playback mode in which a file name is specified, and a cursor selection playback mode in which a playback image is specified by cursor operation on a multi-screen.

The device of this embodiment includes a remote control unit 34, which can be used to input instructions from the operator.

This embodiment can also perform a system batch that automatically runs a plurality of programs by storing a plurality of procedure files +8 on the optical disk 14 and selectively running those procedure files according to a desired program. This system patch is also controlled by the system control unit 32.

A further feature of this embodiment is that while viewing and listening to images and audio reproduced by the reproduction device 12, reproduction conditions such as the order, time, and effects can be modified. Initially, the playback procedure is recorded on the procedure file floppy 16. This is a provisional version created using a word processor 26 or the like. However, when the audio and images recorded on the data file floppy 10 are actually monitored using the procedure recorded on the procedure file floppy 16, it is often necessary to slightly modify the playback conditions. Therefore, the playback device 12 of this embodiment operates the keyboard 50 (FIG. 2) of the system control unit 32 to change the playback order, time, effects, and other procedures, and thereafter performs playback under the changed playback conditions. Has an editing function. The finally determined procedure file 16 may be recorded on the optical disc 14.

As described above, according to this embodiment, it is possible not only to simply display a photographic image, but also to organically combine other information such as audio and text to increase the production effect. These connections can be changed freely by the user on site. Furthermore, since a write-once optical disc is used as the main storage medium, additional information can be recorded on-site, making it suitable for applications where content is frequently added or updated.

In the specific configuration of the playback device 12 shown in FIG. 2, when the data frame 10 is set in the floppy disk device 28, data such as images, sounds, or characters stored therein are read out to the optical disk 14. This will be stored. These data constitute a data file 52 by randomly writing images, sounds, or characters onto the optical disk 14 according to the floppy 10 set in the floppy disk device 28. System control unit 3
2 creates a directory 54 indicating in which address a of the optical disc 14, that is, track and sector, the data is stored, and writes this onto the optical disc 14. Therefore, the directory 54 forms a table that specifies the file name n, data type C, and version V of the data of the data file 52 in correspondence with the address of the data file storage area of the optical disc 14.

The procedure file recorded on the floppy disk 1B is also read out by the floppy disk device 28. In this embodiment, this is read each time it is used. Alternatively, for example, in the case of a finally determined procedure, the procedure may be configured such that it is first read from the floppy disk 16 onto the optical disk 14, and the optical disk 14 is accessed when used. The record format of the procedure file used inside the playback device 12 consists of a header record 100 illustrated in FIG. 3, and scene data records 120 and 140 illustrated in FIGS. 4 and 5.

Header record 100 has file type 102. Number of repetitions (RECUR) +04. Program name 106. Number of scenes: 1082:11Ji110. It consists of six i] effect fields: and CS voice +12. The scene number 114 is set to a predetermined value indicating that it is a header, for example "0".

The file type 102 defines the playback mode and specifies one of fully automatic playback, sequential playback, and interactive playback.

The repeat count 104 defines the number of repeat playbacks in fully automatic playback. The program name 108 uses alphanumeric characters and Chinese characters in this embodiment, and defines the name of a program in which a series of images, sounds, and characters are performed. The number of scenes 108 defines the number of subsequent scenes included in the program, and the length of the program is defined by the time 110. In the case of the fully automatic playback mode, the type C and version V of the audio signal are further defined in the C5 audio 112.

The scene data record 120 shown in FIG. 4 is used in the fully automatic playback mode, and the scene data record 140 shown in FIG. 5 is used in the sequential playback 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 scenes in a particular program. Scene data 1/co 1”120 for fully automatic playback is as follows after scene number 122.
Video file full path name 124. Related file information 12
B, switching time 128, delay effects 130, and special effects 132 fields follow.

The video file full path name 124 defines a file name n, data type C, and version V. In this embodiment, alphanumeric characters and kanji are used for the file name n, such as r
Natural M word notation such as FUJIsAN J is used.

The related file information 126 defines the type C1 of the video signal and the version V of the caption, font, audio, and descriptor. For example, r FUJ l5AN,N
OOJ is defined as image data of the first edition of the normal mode with the title rFUJIsAN J. These file name n1 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 (S) and TV frames (F). For effect e, effect delay field 130 and special effect field 132 are available. type of effect,
For example, video effects such as cut, scroll, wipe, and dissolve are specified by effect number, and character layer, scroll control, character color control, etc. can be specified.

Furthermore, for example, when setting a delay time in addition to screen switching during scrolling, it is defined in the effect delay 130.

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

Returning to FIG. 2, the procedure file 72 stored on the floppy 16 or on the optical disk 14 has a file name n, data type C1 version V, and time t for a certain program.
and details of effect e are specified in the form described above. On the other hand, image data, audio data, and character data are randomly stored on the optical disc 14. For example, when playing a certain program, the program's procedure file floppy 16 is transferred to the floppy disk device 28.
, and specify the program name 106 from the keyboard 50 and input pest instructions. In response to this, the system control unit 32 supplies a step pulse 56 to the address counter 58 from the internal clock.

The address counter 58 is stored in the internal procedure file 7.
This is a counter that generates an address specifying the storage location of No. 2, and increments in response to the step pulse 56.

From the procedure file 72, address counter 5
Scene data record from the sequential storage position according to the step of 8! 20 or 140 are read. Data type C1 effect e and time t are held in switching circuit 62, memory 64 and memory 6B, respectively, and file name n, data type C and version V are held in matching circuit 68.

The system control unit 32 also increments the address counter 70 of the directory 54, and sequentially reads out the file name n, data type C, and version V stored in the directory 54. Matching circuit 68 thus directs directory 54
The file name n, data type C, and version V sequentially read from the procedure file 72 are compared with those read from the procedure file 72.
The address counter 70 continues to increment. If they match, the address a currently read from the procedure file 72 is held in the register 74, and is set in the address register 78 of the data file 52. Therefore, from the data file 52, the data at the address specified by address 1/distaff 8, that is, image, audio, or character data, is read out to the output port 78.

The memory 30 has two storage areas each for a character memory bank CM, a video memory bank VM, and an audio memory bank AM, each of which is alternately switched by switches 84, 86 and 88 to perform writing. Writing from the data file 52 to the memory 30 is selected by the switch 80 depending on the type C of data. First, data type C from the internal procedure file 72.
The switching circuit 62 to which is set sets the connection position of the switch 80 according to the data type C.
When data is read from the data file 52, the data is stored in the bank of the memory 30 according to type C.

The image data is written to the video memory bank V (or V) 12. The video memory bank VMI or VH2 is
Each has a storage capacity for one frame. The image data written in these video memories is read out to the video circuit 204 in real time, that is, at the TV signal rate. The video circuit 204 converts the image data into a corresponding analog signal, applies necessary effects, and outputs it to the image receiving file. The effect provided by the video circuit 204 is specified by decoding effect information e read out from the procedure file 72 into the memory 64 by the decoder 98. The video circuit 204 applies image effects such as cut, scroll, wipe, and detrube to the video signal, and outputs the video signal to the receiver 18 .

The video circuit 204 also includes a DPCM decoder (not shown).
, which decompresses the band-compressed image data.

DPCM mode is type C of procedure file 72.
Since it is recorded in , when it is read out to the switching circuit 62, the same circuit 62 energizes the DPCM decoder of the video circuit 204. As a result, the video circuit 204
Expands the encoded video signal.

In fine mode, the DPCM decoder is not operated.

For example, while image data for one scene is being played back from one area, eg, bank V old, image data for the next scene is read from data file 52 and written to the other bank VM2.

A switch 8B is arranged on the write input side of the image memory banks VMI and VH2, which alternately switches its connection position in response to the switching circuit 206. This image data is read from the data file 52 and written to the memory bank VM2 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 the procedure data of the next scene.
The image data of the scene in the order specified by the procedure file 72 is transferred from the data file 52 to the image memory VM2.
Or alternately written to V old.

Character data is similarly written to and read from character memory banks C old and 0M2. The video circuit 204 inputs the image read from the image memory bank VMI or VH2 to the character memory bank C old or CM2.
The characters read out are superimposed and output to the receiver 18.

As a result, the telop, font, or disc libter is reproduced.

By the way, image effects that require changes over time can be created using the matching circuit 94.
It is executed according to instructions from. The timing of applying the effect is monitored by a coincidence circuit 84. The device 12 includes a timer 86 that defines an internal time, and a matching circuit 94 monitors the point in time when the time generated by the timer 86 matches the time t set in the procedure file 72 in the memory 66. If there is a match, match circuit 94 energizes decoder 88. A switching circuit 206 is connected to the decoder 98 as shown. The same circuit 206 is connected to the monitor 1
It is determined whether the reproduced image of No. 8 can be switched and whether the special effect has ended, according to the effect specified by the decoder 98, and the switches 84 and 86 of the memory 30 are controlled. In this way, the special effects are generated by the video circuit 204 and the switches 84 and 96 based on the effect information e and time information t of the procedure file 72.

As mentioned above, the amount of image data is fixed,
The image data of one scene is read into the image memory bank VMI or VH2 at once. However, when all of the audio data stored in one area, for example bank Al, is played back, the next audio data is written there.

A switch 90 is arranged on the read output side of the audio memory banks AMI and AM2, which alternately switches its connection position while taking a connection position opposite to that of the switch 88 on the write side. In this way, while audio data is being read into one audio memory bank AMI, the audio data stored therein is read out 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, thereby maintaining audio continuity.

Switching of switches 88 and 80 for audio memory banks 8 and AM2 is controlled by counter 200.

Since the amount of audio data stored in audio memory banks 8 and AM2 is constant, the duration of audio played from it is constant. Counter 200 monitors the time limit. When the predetermined time limit is reached, the counter 200 toggles the switch 90 and energizes the interrupt circuit 202. The zero interrupt circuit 202 then registers the address register 7.
The address register 76 is incremented by the G adder circuit 78a. At the same time, the interrupt circuit 202 interrupts the write side switches 8 of the audio memories AMI and AM2.
8 to interrupt the data file 52 for reading. This is because audio reproduction requires real-time performance, so reading out audio data should be prioritized over reading out image data. In this way, a series of sounds are read out one after another from the data file 52 and continuously reproduced from the speaker 20 using the sound storage areas AMI and AM2 alternately.

For example, in the case of fully automatic playback mode, the matching circuit 94 also monitors the switching timing of displaying one scene of images. When the time of the timer 96 matches the time t set from the procedure file 72 in the memory B6, the coincidence circuit 84 activates the decoder 88 to give an effect instruction to the video circuit 204 while switching the switch 84 by the switching circuit 206.
and 88 to play the next scene. This switching of reproduced images and sounds continues until all scenes set in the procedure file 72 of a particular program are completed. When the fully automatic regeneration ends, the system returns to its initial state.

In the manual trigger mode of the sequential reproduction 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. This allows the screens to switch in forward or reverse order according to manual instructions, and playback occurs in the programmed order.

In the audio-triggered mode, the system controller 32 performs image conversion in response to the generation of an interrupt by the interrupt circuit 202.

In other playback modes, such as conversational playback mode,
The system control unit 32 displays a question/answer selection option or a multi-screen on the video monitor device 18, and when an answer is answered from the keyboard 50, the desired information is read out from the data file 52 in the same manner as described above by referring to the directory. and played.

By the way, in this embodiment, editing can be performed by operating the keyboard 50 of the system control unit 32. For this editing function, the playback device 112 uses the attribute (A) register 210.
It is equipped with The A register 210, the related part of which is shown in FIG.
Data and instructions for editing 0, which is a register for rewriting the corresponding item, are input from the keyboard 50 in natural language. The input editing data or instructions are converted into a machine code by the code conversion section 212 and inputted to the system control section 32.

Editing is performed by changing procedure data in 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 input to the system control unit 32. Therefore, the system control unit 32 closes the suite 214 corresponding to the specified file attribute.Next, when the data of that attribute is inputted from the keyboard 50, this data is converted into machine code by the code conversion unit 212 in the same way. It is converted and stored in the storage location of that attribute in the A register 210 through the corresponding switch 214. In this way, desired attribute data is set in the A register 210. Therefore, when an execution instruction is input from the keyboard 5o, the system control unit 32 sets the relevant address in the address counter 58 of the procedure file 72, and writes the contents of the A register 210 to that storage location in the procedure file 72.

The present device 12 can also use this editing function to create a new procedure file 72, for example.

In that case as well, the procedure file 72 is created using the above-described operating procedure, but the version V is set to rQJ. Further, the switching time t is set to a rough value according to the scenario.

Let me explain some examples of editing. For example, changing the scene switching time may be done when actually playing the program according to the already created procedure file 72 does not satisfy the scenario author's intention and wants to correct it, or when changing the audio for image switching. It is effectively used when you want to adjust the timing with high precision. Referring to FIG. 2, images and sounds are played by the operations described above, while
As mentioned above, the timer 86 measures the internal time.

When the operator operates a switching time designation switch (not shown) on the keyboard 50 at the time when he wants to switch the image or audio, the system control unit 32 responds to this by switching switch 2.
Close 1B. As a result, the time measured by the timer 96 is set in the switching time field t of the A register 210. The contents of the A register 210 are later written to the procedure file 72, thus modifying the transition time t of the playback scene of the procedure file 72.

In order to try the procedure file 72 in which the switching time t has been modified, the operator inputs the instruction from the keyboard 50, and the system control unit 32 decrements the address counter 58. Therefore, the operator uses keyboard 5
If playback is instructed from 0, the playback operation will be performed from the scene immediately before switching, and it can be confirmed whether the switching of images or audio has been set at the timing according to the scenario. Of course, it is also possible to initialize the system and instruct to playback from the beginning of the program.The procedure file 72 with the playback conditions finally determined can be created by operating the instruction keys (not shown) on the keyboard 50. is written on the optical disc 14 for later use.

When revising specific data in the data file 52 recorded on the optical disk 14, for example, an image of a certain scene, first, the data file floppy IO is loaded with the scanner 2.
2, new image data is recorded. At this time, the file name n uses the same name as the old image data file to be revised. The data file floppy disk 10 on which the new image data has been recorded is set in the floppy disk device 28.

When an instruction to read the data file floppy 10 is input from the keyboard 50, the system control unit 32 responds to this by reading the data file from the floppy 10, writing it to the free area of the optical disk 14, and setting the address a of the free area. Set in 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, this header record includes the file name n of the data, the data type C1 version V, and the address a on the floppy 10.

Therefore, the system control unit 32 sequentially reads directory data from the directory 54 of the optical disk 14. The file name n and data type C of this directory data are taken into the matching circuit 68, and the corresponding header record read from the floppy disk 10 is inputted into the matching circuit 68. be compared with something. The system control unit 32 increments the address register 7B until the former matches the latter, and reads directory data n and C from sequential storage locations in the directory 54.

If they match, the minus number circuit 68 loads the header record of the data floppy 10 into the A register 2nd 8th. The contents n, C, V, a of A register 210 are then written to that storage location in directory 54. At this time, the old directory data read from the directory 54 is written to the directory 54 with the value of the version field V incremented. Therefore, from now on,
The new data is used as version "0" and this new data file is available from optical disk 14 without updating procedure file 72.

In this embodiment, when audio data is input from the floppy disk device 2 while a certain scene is being played back, this audio data is added to the file name n of the image data being played back and stored in the data file 50 of the optical disk 14. will be written to. For example, first, audio data is recorded on the floppy 10 by the audio input device 24. This audio data does not need to be given a file name n.

Next, as shown in FIG. 8, this audio data file floppy 10 is set in the floppy disk device 28. Therefore, 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 uses the address counter 70 to search for the file name n, etc. in the directory 54 as described above, reads image data from the optical disc 14, and performs a playback operation. The data directory is read and its file name n is held in the A register 210.

When an audio recording instruction is input from the keyboard 50, the system control unit 32 responds to this by reading the recorded audio data file from the floppy disk 10 and writing it to the free storage area of the optical disk 14. a is set to 0 in the A register 210
Next, the system control unit 32 controls the type C of the A register 210.
to "audio" and version V to "0", and set the contents n, c, v, a of the A register 210 to the directory 54.
write to.

As a result, the audio data written on the optical disc 14 can be used as the audio data of the file name n and version V specified by this directory data in the directory 54 from now on.

Such automatic assignment of the file name n is also applied to other types of data other than audio. For example, if character data is input from the floppy disk device 28 while image data is being played back, this character data will be given the same file name as the image data being played back and written to the optical disk 14 in the same manner as described above. The invention thus provides that the procedure for reproducing independently created data files of different types from a mass storage medium in which these data files are randomly stored is defined by a procedure independent of the data files; The data reproduction can be edited as desired by modification.

Data files are created at the production site appropriate for the characteristics of each data such as images and audio. Therefore, a large amount of information resources are effectively utilized. These data files are indexed using a common file name, and the procedure file is played back using this file name, and editing is also performed using this file name as a key. Therefore, the degree of freedom in file configuration is great, it is possible to immediately respond to requirements from program production, and the functional limitations of conventional devices are alleviated.

As described above, according to the present invention, it is possible not only to simply display photographic images but also to organically combine other information such as audio and text to increase the presentation effect. These combinations can be freely changed by the user on site, and if a write-once optical disk is used as the main storage medium, additional information can be recorded on site, making it suitable for applications where content is frequently added or updated. .
