It is also possible to record information of a track head entry point indicating break information of an audio track, and to have information unique to various audio tracks in the track head entry point.

4. When the user specifies a still image to be displayed simultaneously during audio track reproduction, the display timing of each still image during audio information reproduction is automatically calculated from the reproduction time of the audio track and the set number of still images. The display timing information can be automatically recorded in the management information.

[0015] 5. The original list and the playlist can be simultaneously displayed on the screen (Audio Recording
Not only for Video Recording but also for Video Recording).

6. According to the present invention, a new track can be created on the playlist by collecting a part of the original tracks in the original list. Alternatively, the inside of the original track can be partially erased. In such a case, the following (A) and (B) can be selected according to the information content of the display mode of the original track. At the time of reproduction, (A) use all still images displayed at the time of original track reproduction as still images displayed at the time of reproducing a new track on the playlist, or partially delete all still images displayed before partial deletion. All will be displayed later.

(B) Of the still images displayed during the reproduction of the original track, only the still images within a specific range are used for the still images displayed during the reproduction of a new track on the playlist, or are displayed within the partial erasure range. The erased still image is not displayed after partial erasure.

Which can be determined,
Set as a still image for a new track on the playlist.

7. An arbitrary screen of a movie object can be extracted as a still image and registered in the still picture AV file information table as a still image that can be displayed simultaneously with the audio object.

8. Further, in the present invention, the designation information of the representative image indicating the track content is designated in the management information in the management information, and the designation information of the representative image is the same as the designation information of the still image displayed at the time of reproducing the audio track.

A list screen for the original track 1 is created in the PU unit 404 (S32), a list screen for each track for the playlist # 12 is created individually (S33), and both screens are combined and displayed (S34). (S35).

The row of picture 5 in FIG. 6 indicates a "representative image" which is a still image indicating the contents of each track. In the embodiment of the present invention, a still image displayed first when audio information is reproduced is often used as a representative image. However, the present invention is not limited to this, and a structure is employed in which a representative image can be designated separately from a still image displayed first. . The display mode 7 indicates a method and timing of switching the still image to be displayed at the time of reproducing the audio information. The display order mode (Display Order Mode) includes:-Sequential: Still images to be displayed in a predetermined order. How to switch images.

Random: The display order of the still images is set completely at random.

(In the worst case, the same still image may be displayed successively.) Shuffle: The display order of the still images is changed with respect to the order specified in advance.

(The same still image is displayed only once in one cycle.) Display timing mode (Di
As for the splay Timing Mode: ・ Slideshow (Slideshow)… Switches to the next still image at a predetermined timing.

[0104] Browserable (Browsable): The next still image is switched only when the user turns on the switch.

(The same still image is displayed until the user turns on the switch.) The display mode 7 is set for each track, and the display mode does not change within the same track.

A time chart (Time Chart) 11 is a visualization of a designated range when a user designates a part of an original track when a play list is created.

The display screen of the original track 1 in FIG. 6 and the data structure of the management information for it will be described with reference to FIG. All the information on the original track 1 in FIG. 6 is managed in the original program chain information 144. The concept is schematically illustrated by an original PGC 320 shown in FIG. For the original track, the program corresponds to each track,
Original track = 1 program. Information about each original track as shown in FIG. 9 is described in program information # 1 311 to # 5 305 which is a management information recording area for this program.

One program is composed of one or more original cells, and a management information recording area of original cell information # 1 301 to # 5 305 exists for each original cell. In the original track 1 (original PGC320), all original cells #
AOB # 1 one-to-one with respect to 1 301 to # 5 305
To # 5, and 1 cell = 1 AOB.

The correspondence between FIG. 6, FIG. 7, and FIG. 8 will be described below. The audio information of the track name (song name) called "Automatic" shown in FIG. 6 is recorded in AOB # 1 in the AR_AUDIO.ARO221 file, and the management information on the original track is recorded in the program information # 1311 and reproduced. Related to the original cell information # 1 30
It is recorded in 1. Similarly, audio information of a track name (song name) called “First Love” is recorded in AOB # 2 in the AR_AUDIO.ARO221 file, management information on the original track is recorded in program information # 2 312, and information on reproduction is recorded. Is the original cell information # 2
302. “Another Ch immediately after recording
The audio information of the track name (song name) called "ance" is one A
Although it was managed as an OB, since a part of the track was partially erased, it was divided into two AOBs, AOB # 4 and AOB # 5, and divided into original cell information # 4304 and # 5305 accordingly. (Figure 7
(E)). However, since the track itself does not change, one program information # 4 314 is maintained.

The user creates a new track in the playlist desired by the user through the editing process using the screen shown in FIG. For example, as shown in FIG.
2 is created. That is, “Automatic”
A new track No. 1 is created by connecting the range from A to B and all of “Another Chance”, and a still image to be displayed during music playback is a still picture shown in FIG. Set 4 sheets up to No.4. Then "I
n Change the still image displayed in “My Room” to New Track No. 2, connect A to B of “First Love” and C to D of “Automatic”, and select still pictures No. 7 to No. The three still images up to No. 9 are set as New Track No. 3.

FIG. 7 shows the relationship between the management information on the playlist created as a result and the original PGC, and the audio object file AR_AUDIO.ARO 221
Is shown in FIG. Cell information # 1 164 to # 6 are respectively added to a part of each original track.
169 corresponds to the cell information # 1 164 to # 616.
9 includes still picture entry points 21 to 26 in which management information for still images to be displayed on the second and subsequent frames in each track is recorded. Each cell information # 1 164 to # 6 169 includes "corresponding audio object information (AOB) # 1 196 to #i 1
97, and "information on respective start and end times" are recorded, and audio object entries # 1 to # 5 (audio object unit entry #) in corresponding audio object information # 1 196 to #i 197 are recorded. 1 241 to # h24
The access address on AR_AUDIO.ARO 221 can be determined with reference to 8).

The information contents recorded in the track head entry points # 1 171 to # 3173 and the still picture entry points 21 to 26 shown in FIGS. 7 and 8 will be described with reference to FIG. “Information for specifying the storage location of the still image to be displayed” is shown in FIG.
Still picture VOB group information # 12 shown in (h)
The corresponding still image is designated by the number designation information of 73 to # g279 and the number designation information of still picture VOB entries # 1 281 to # f289 therein. FIG. 10 schematically shows a method of specifying the still image information.
It is.

In FIG. 10, all the still images are grouped into A for each still picture VOB group # 1 to #g.
The management information of each still image recorded in the R_STILL.ARO 213 file is the still picture V in the still picture VOB group information # 1 273 to # g279.
It is recorded in the OB entries 281 to 299. FIG.
"Information for specifying the storage location of the still image to be displayed" is the track head entry point # 1 in FIG.
171 to # 3 173 and “solid arrows” from the still picture entry points 21 to 26 to the still picture VOB entries 281 to 299.

The “timing designation information for displaying a still image” designated in FIG. 9 indicates that the sequential mode (“Sequential Mode”) is designated as the display order mode (Display Order Mode), and the display timing mode (Display Timing Mode) is designated. ) Is timing specification information that is valid when a slide show (“Slideshow”) is specified, and switches the display to a still image specified by the corresponding still picture entry point 21 to 26 with respect to the already displayed still image. Means time information.

In the above display mode, the following still picture entry points 21 to 26
The still image specified here is continuously displayed until the time specified by or the time at which the corresponding track ends. In the present invention, the display time information of audio information (Presentati
on Time), but the present invention is not limited to this.
For example, difference time information from the reproduction start time of the corresponding track to the time when the display is switched to the specified still image can be used. The “display time range information of the corresponding still image” is valid when the display timing mode is set to the browsable mode (“Browsable Mode”).

When the user presses the switch, the previously displayed still image is switched to the still image specified by the still picture entry points 21 to 26. If the user does not press the switch thereafter, the corresponding track ends. Until the same still image is displayed. When the maximum display time is set in the “display time range information of the corresponding still image”, the display of the corresponding still image is automatically stopped if the user does not press the switch for changing the still image until that time. Processing such as switching the screen to a “blue back” is possible. Conversely, if the user accidentally presses the still image changeover switch, the still images are immediately changed one after another, and the user cannot calm down and see the still image. When the minimum display time is set in the “display time range information of the corresponding still image”, even if the user keeps pressing the still image switching switch, the still image to be displayed is not switched during the minimum display time set here. Can be

Track head entry point 171
173 or the still image specified in the program information 311 to 314 is always displayed at the same time as the reproduction of the corresponding track is started, so that the “timing specifying information for displaying the still image” is unnecessary. According to the present invention, it is possible to independently set a representative image for each track by using "information for specifying a storage location of a representative image representing the content of the corresponding audio track" separately from being displayed simultaneously with the start of reproduction of the corresponding track. Has become.

[0097] "Information for designating a storage location of a representative image representing the contents of the corresponding audio track" shown in FIG.
The still image designated by corresponds to the still image displayed in the column of the pictures 5 and 6 in FIG. The “information specifying the storage location of the representative image representing the content of the corresponding audio track” shown in FIG. 9 is obtained from the track head entry points # 1 171 to # 3 173 and the still picture entry points 21 to 26 in FIG. This corresponds to a “dashed arrow” directed to each of the still picture VOB entries 281 to 299.

As described above, the display mode 7 for a still image is set for each track, and the display mode does not change within the same track. Therefore, track head entry points 171 to 173 or program information 311 as track-specific information. ~ 314
Is recorded within. The contents set in the “display mode (display mode) of a still image in the corresponding audio track” in FIG. 9 are displayed in the display modes 7 and 8 in FIG.

The contents of the “text information (Primary Text information) specific to the relevant audio track” in FIG. 9 correspond to the primary text information 51 to 53 in FIG. Song name
Is displayed in the column of "track title 3" in FIG. The “additional explanation text information” in FIG. 9 corresponds to the “arrow” directed from the track head entry points # 1 171 to # 3 173 to the item texts # 1 236 to #e 238 in FIG.
It has information content indicating “item text number”.

The information content of "Relationship of still image content to be displayed with original track" in FIG. 9 is displayed in "still 10" in FIG. That is, the still images displayed in the new tracks No. 1 to No. 3 in FIG. 6 use the still images used in the original track 1 as they are (in this case, they are displayed as “original”) or the original track 1 Is the user's own setting separately from the still image used in (in this case, “newly set”)
Is displayed).

In the present invention, the unit of setting whether the area is an erasable area or a non-erasable area is set for each track. Therefore, information for which the “erase prohibition flag” is “1” is set for an audio track whose erasure is prohibited.

As shown in FIG. 10 (h), any video screen in the VR_MOVIE.VRO212 file in which video information (movie object) is recorded can be used as a still image to be displayed simultaneously with the reproduction of audio information. There are features. FIGS. 10 and 22 and FIG.
3 will be described. First, as shown in FIG. 6, a list of audio tracks recorded on the information storage medium 100 is displayed to the user, and the user specifies a track for which a still image is to be set (S63). Next, VR_MOVIE.V
While displaying the video information recorded in the RO212 file, the user specifies a desired screen (scene) (S6).
4). Since the screen (scene) designated by the user has already been decoded in the decoder unit 402 in FIG. 14, the image information is recorded as it is as a still image (I picture) in the AR_STILL.ARO 213 file on the information storage medium 100. Is performed (S65), and management information related thereto is created (S66). The display relationship information between the created still image and audio information is recorded at the track head entry point # 2 172 or the still picture entry point 24. A general user sets a desired screen (scene), but often does not set until a display timing. Therefore, the value of the "information for specifying the timing of displaying a still image" (FIG. 9) is automatically set in the MAIN MPU unit 404 in the information recording / reproducing apparatus shown in FIG. 14 (S68 in FIGS. 22 and 23). However, there is a feature of the information recording / reproducing apparatus according to the present invention.

Specifically, it is automatically calculated as [display time per still image] = [reproduction time of the corresponding audio track] ÷ [number of still images to be displayed in the relevant audio track].

In the original PGC 320 for managing the information on the original track, the information on the original track shown in FIG.
4314. Program information # 1 3
FIG. 12 shows the setting status of still images in 11 to # 4 314.

FIG. 12A shows a still picture corresponding to an original audio track (FIG. 12B), and FIG. 12C shows an original program chain. Here, program information corresponds to each original audio track. Then, information 41 to 4 for designating a representative image indicating the content of each audio track is included in the program information # 1 311 to # 4 314.
4 is recorded and the still picture V
OB entry # 1 281 to # p + 1296 (FIG. 12
(G)). FIG. 12 (g)
Is a separate file, which is still picture VOB group information.

Original cell information # 1 301 to # 5
The track head entry point information 305 has no track head entry point information (including a still image displayed at the start of audio track reproduction), and all information includes only the still picture entry points 31 to 39.

In the management information, the representative image designation information 4
1 to 44, which are designated for each track and function as designation information of a representative image indicating the contents of the track. The above-described representative image designation information is provided separately from the still image designation information displayed during audio track reproduction. For this purpose, a video object (VO) in which a still image held during audio track reproduction is recorded.
B) An arbitrary still image in a VOB group located in another place other than the group can be set as a representative image, and the degree of freedom can be increased.

FIG. 13 shows still another embodiment or an embodiment which coexists with the above embodiment. Here, the setting status of the text information in the program information # 1 311 to # 4 314 is shown in FIG. The “text information specific to the corresponding audio track” in FIG.
As shown in (d), program information # 1 311 to # 4
314 is recorded in primary text information 56 to 59. The “additional explanation text information” in FIG. 9 is the item text # 1 236 to # e2 in FIG.
Corresponding to the "arrow" heading to 38, information of "what item text is to be designated" is recorded.

In the above description, the recording / management location of the unique information related to the audio track as shown in FIG. 9 is as follows: In the case of the original track, it is recorded in the program information and managed. In the case of a playlist, it is recorded and managed within the track head entry point. The case has been described.

However, the present invention is not limited to the above method, and the recording / management place of the specific information on the audio track is reversed, or both are recorded in the same place.
Management is also included in the scope of the present invention.

That is, the program information exists in the user-defined PGC for the playlist, and the unique information on the audio track as shown in FIG. 9 is recorded and managed in the program information in the user-defined PGC. Are also included in the scope of the present invention.

Next, a method of recording voice-related information on the information storage medium 100 will be described with reference to FIGS.

In most processes according to the present invention, information in the management information recording area 130 recorded on the information storage medium 100 is read and temporarily recorded in the work RAM section in the MAIN MPU section 404 (S1). Then, after a series of processes, a process (S12) of recording the management information, which is recorded in the work RAM unit and partially changed in content, on the information storage medium 100 is performed.

In the embodiment of the present invention shown in FIGS. 15 and 16, first, audio information is additionally recorded after the AR_AUDIO.ARO 221 file (S2), and thereafter, processing for rewriting the management information in the work RAM unit is performed. To change the content of the management information, first, the management information on the audio information is additionally written in the audio object information.

That is, in step S3, the main MPU
In the unit 404, program information, original cell information, and audio object information are created in accordance with the audio track recorded in step S2, and the work RA
Record additionally in M section. Further, in step S4, the AR_AUDIO. The relative address in the ARO 221 is checked, and additionally recorded in the audio object information in the work RAM.

Next, an inquiry is made to the user as to whether a still image to be displayed simultaneously with the audio information is to be set (S5). further,
Even when setting a still image to be displayed simultaneously with sound (1) When recording a new still image at the same time as recording audio information (YES in step 6), the still image to be newly recorded is stored in the AR_STILL.ARO 213 file. Record.
Correspondingly, still picture management information still picture VO
Create B group information. That is, the still image information is represented by A
The still picture VOB group information is recorded in the R_still picture object recording area 132 (added to the trailing end of the AR_STILL.ARO 213 file), and is additionally recorded in the work RAM (S7).

(2) When using a still image already recorded on the information storage medium 100 (NO in step 6), the user is asked to select a still image to be displayed simultaneously with the audio information (S8). . That is, the user selects a still image that the user wants to simultaneously display on the corresponding audio track from the still picture VOB group already recorded in the information storage medium 100.

One of the methods is selected.

The information content of “designation information of timing for displaying a still image” set at the still picture entry point is described in MAIN MPU section 4 of the information recording / reproducing apparatus of FIG.
In 04, the calculation of [display time per still image] = [reproduction time of the corresponding audio track] ÷ [number of still images to be displayed in the relevant audio track] is performed (temporarily recorded in the work RAM unit). The value of the calculation result is recorded for “designation information of the timing for displaying a still image” in the still picture entry points 31 to 39 that are present) (S9).

Next, "information for designating a storage location of a representative image representing the contents of the corresponding audio track", which is recorded in the program information 311 to 314 and set for each audio track, "text specific to the corresponding audio track" The user inputs information such as "information", "text information for additional explanation", "display mode of still image in the corresponding audio track", and "erase prohibition flag" (S10, S11).

That is, in step S10, the user sets the "representative image for the corresponding audio track" as the "still image display mode", and the information is temporarily stored in the work RAM unit.
Record within 1-314.

Next, at step S11, the key input unit 407
, The user sets "primary text information" and "item text information", and stores the information in the primary text information 56-59 and the item text 236-23 temporarily recorded in the work RAM unit.
8 as well as pointer information to the item text.

Although not shown, when the unique information for each audio track is recorded in the program information 311 to 314 (step S10), the "display range of the representative audio indicating the contents of the corresponding audio track" shown in FIG. Is automatically recorded from the reproduction start time of the corresponding audio track to a specific time (for example, 5 seconds). If the user wants to change this time range, the user can reset the display range of the representative voice during the editing process.

Through the above series of processing, management information relating to audio-related information is completed, and the management information is recorded on the information storage medium 100 via the disk drive unit 409 (S12).

A method for partially erasing an original track according to the present invention will be described. 7 (e) and 7
As shown in (f), when the central part of the original track of the track name (song name) called "Another Chance" is partially erased, the audio object is divided into two such as AOB # 4 and # 5. Also, correspondingly, audio object information, original cell information # 4 304,
# 5 305 is divided into two. A processing method in the information recording / reproducing apparatus at that time will be described with reference to FIGS.

In FIGS. 17 and 18, when the user designates the partial erasure range with time information (S22), the content of the management information is changed correspondingly (S23), and the AR_AUDIO.ARO 221 is changed.
The corresponding part in is deleted. Handling of a still image displayed within the partial deletion target range becomes a serious problem.

As a method of handling the still image after the partial erasure, (A) regardless of where the partial erasure is performed, all the still images before the partial erasure are displayed at the time of reproducing the audio information after the partial erasure (S2).
7)... In this case, the “designation information of the timing for displaying a still image” in FIG. 9 is recalculated and automatically rewritten.

(B) The still image displayed only in the partial erasure location is not displayed during reproduction after the partial erasure (S2).
8).

The two methods are selected in the present invention. At this time, information for determining whether a still image displayed only in the partial erasure location (a specified part of the still image) can be displayed is recorded in advance in the management information. Where one of the appending (A) and (B) is selected (S26 in FIGS. 17 and 18), the first in the editing method of the present invention is performed.
There is a feature.

A second feature of the present invention resides in that the determination information is information that can be recognized by the user.
If the user can recognize the situation, the user can understand which of (A) and (B) has been selected, and confusion of the user can be avoided. In the present invention, the display mode 7 shown in FIG. 6 is used as the determination information that can be recognized by the user.

That is, the display mode 7 of the original track 1 indicates “Slideshow + Sequential” (the same information is recorded in the “display mode of a still image in the corresponding audio track” in the program information at that time). (B) is selected only when the information is present, and (A) is selected when other information is recorded.

A more detailed description will be given with reference to FIGS. In step S21, the disk drive unit 409
Reads the information in the management information recording area 130 in the disk and temporarily records it in the work RAM section in the MAIN MPU section 404. In step S22, the user designates a range (partial time information) for partially erasing the original track.
In step S23, for the audio object information including the original track specified by the user,
The audio object is divided into two parts before and after the partial deletion range designated by the user. The existing audio object information is used for the audio object in the first half (before the part to be partially erased), and unnecessary audio object unit entries are deleted (main MPU unit 4).
04) is performed. Similarly, for the audio object in the latter half (after the part to be partially erased), one piece of audio object information is newly created, and the corresponding part is copied from the original audio object unit entry and recorded in the RAM unit and the like. .

[0133] In step S24, AR_AUDIO. ARO 22
Erase the partial erasure range in one file. Then, in the next step S25, it is determined whether or not to display the still image displayed within the partial erasure range specified by the user after the partial erasure based on the display mode information on the still image information recorded in the program information on the corresponding original track. The determination is made in the main MPU unit 404.

If the corresponding still image is to be displayed after partial erasure (YES in step S26), the display time of the audio track after partial erasure is divided by the number of sex images to be displayed, and the display time per still image And calculate the work R
The contents of the “information specifying the timing of displaying a still image” in the still picture entry points 31 to 39 temporarily recorded in the AM unit are changed. Conversely, when the corresponding still image is not displayed after partial erasure (step S26)
No), the information of the still picture entry points included in the partial erasure range designated by the user is deleted from the still picture entry points 31 to 39 before the partial erasure recorded in the original cell information 301 to 305. (S28).

In the next step S29, the management information temporarily recorded in the work RAM is transferred to the disk drive unit 409.
Over the management information recording area 130 in the information storage medium via

Next, with reference to FIG. 19, a description will be given of a processing method of creating a display screen for creating a playlist as shown in FIG.

The information in the management information storage area 130 in the disk is read by the disk drive
Temporarily store in the work RAM section in the U section 404 (S3
1). Next, the main MPU unit 404 interprets the information on the original track recorded on the disc 100 from the information content of the temporarily stored program information 311 to 314, and creates the display screen content on the original track 1 (S32). . Next, the main MPU unit 404
Uses the information of the track head entry points 171 to 173 in the cell information 164 to 169 constituting the temporarily stored user-defined PGC information table 145 to extract information on tracks for each playlist, and A display screen content for list 2 is created (S33).

Next, the display screens created in steps S32 and S33 are combined and transferred to the V mixing unit (S3).
4). The display screen created inside the main MPU unit 404 is passed through the D / A converter 436 to the display unit 408.
To display.

With reference to FIGS. 20 and 21, the method of creating a playlist according to the present invention will be further described. The information in the management information recording area 130 is read and the main MPU
Is temporarily recorded in the work RAM section of the section 404 (S4
1).

Next, the editing screen (original track 1, playlist screen) is displayed to the user by the method shown in FIG. 19 (S42), and the user creates a playlist (S43). Here, the user inputs the relationship between the newly created new track and the original track while looking at the screen.

The display mode is automatically set to match the display mode specified by the original track to be reproduced first, but it is possible for the user to change later while looking at the screen. At the same time, the user is requested to input unique information regarding the newly created track on the playlist (S44).

That is, in this step, the display mode 8 (FIG. 6) relating to a new track to be newly created by the user while viewing the display screen, the representative image, and the still image setting conditions (in the case of the original, the original track is set). (In the case of a new set, the user specifies a new still image.)

Next, the information recording / reproducing apparatus shown in FIG.
The MAIN MPU unit 404 creates new cell information and records information in the track head entry point therein based on the above input information (S45).

That is, in this step, the corresponding user-defined PGC information 156, 1
57, cell information 164 to 169 are additionally set.
Track head entry points 171 to 173 are additionally written in the cell information for the cell located at the head in the new track set by the user.

Next, the display mode designated by the user, the designation information of the representative image, and the display range of the representative voice are added to the track head entry points 171 to 173 (S46). In the display range of the representative voice in step S46, the time from the reproduction start time of the newly created new track to a specific time (for example, 5 seconds) is automatically recorded. If the user wants to change the time range, the user can reset the display range of the representative voice during the editing process.

When the user newly sets a still image to be displayed simultaneously with the reproduction of the newly created new track (S47), the still 10 shown in FIG. Original) "to" Newly Set "and the user selects a still image (S48).
That is, the user selects a still image to be displayed simultaneously with the display of a newly created new track from the existing still picture VOB group information 273 to 279.

As a method of setting a still image at the time of creating a playlist, (A) regardless of the place designated by the user in the original track, all the still images possessed by the related original track are reproduced by a new track in the playlist. It is displayed at the time (S51).

... For example, when a new track is created from three original tracks, all the still images displayed when the three original tracks are reproduced are displayed when the new track is reproduced.

(B) Only the still image displayed when reproducing the designated place in the original track cited for creating a new playlist is displayed when reproducing the new track (S50).

The two methods are selected in the present invention. At this time, information for determining which method is to be adopted is recorded in the management information in advance, and based on the information (A),
(B) (S49 in FIGS. 20 and 21)
There is a first feature of the editing method of the present invention in the step (S49).

A second feature of the present invention resides in that the determination information is information that can be recognized by the user. If the user can recognize the situation, (A),
The user can understand which of (B) is selected, and confusion of the user can be avoided.

In the present invention, the display mode 7 shown in FIG. 6 is used as the determination information that can be recognized by the user. That is, the original track 1 (for example, in the example of FIG. 6, the new track No. 1 means "Automatic" of the original track, and the new track No. 3 indicates the original track when the new track is reproduced.) Display mode 7 is "Slideshow + Sequentia"
(B) is selected only when “l” is displayed (the same information is also recorded in the “display mode of the still image in the corresponding audio track” in the program information at that time). If information other than is recorded, (A) is selected.

Although not shown in FIGS. 20 and 21,
Immediately after the setting of the “information for specifying the timing of displaying a still image” (S52), “text information specific to the relevant audio track” and “text for additional explanation” to be recorded in the track head entry point corresponding to the newly created track In the “information”, information in the original track 1 that quotes audio information to be reproduced first when a new track is reproduced is automatically transcribed, and text information is rewritten by a user key-in operation as necessary (S).

That is, when the audio track to be confirmed is specified and the user presses the play button of the representative voice,
In the main MPU unit 404, from “information designating the display range of the representative audio indicating the reproduction content of the corresponding audio track” (S77), the audio object unit entry # 1 241 to #h 248 is used to
R_AUDIO. The address to be accessed in the ARO 221 is calculated (S78), and the audio information is reproduced from the information storage medium and displayed (S79).

Specifically, in step S77, the representative sound of the representative audio is determined from the track head entry points 171 to 173 or the "information for specifying the display range of the representative audio indicating the contents of the corresponding audio track" in the program information 311 to 314. Read the playback start time and playback end time.

In step S78, AR_AUDIO.R.A in which the information of the representative voice is recorded using the information of the audio object unit entries 241-248 in the audio object information 196-197. AR
The reproduction start address and the reproduction end address in O221 are calculated. Then, in step S79, the predetermined address range is reproduced and voice output is performed. The user listens to the representative voice and determines whether or not the audio track is desired by the user. After confirmation, a reproduction range is designated and a reproduction button is pressed (S80). Also, the track range specified by the user from the management information temporarily stored in the work RAM unit is stored in the original PGC information 144 or in the user-defined PG.
It is determined which range in the C information 156, 157 falls (S81).

The arrangement order of the program information 311 to 314 in the original PGC information 144 or the user-defined PGC information 156 and 157 or the cell information 164
The object information is reproduced from the disc for each track unit according to the arrangement order of 169, and output and displayed for each track unit (S82).

As described above, according to the present invention, it is determined which part in each object file the range set by the user in the MAIN MPU unit 404 in the information recording / reproducing apparatus (S77), and based on the result, Play and display with At this time, the arrangement order of the program information 311 to 314 existing in the original program chain information 144 or the user-defined PGC information 156 and 157 or the cell information 1
The feature of the present invention resides in that object information is reproduced from the information storage medium 100 for each track unit in accordance with the arrangement order of 64-169.

The following is a summary of the points executed in the present invention.

Decide which still image to display after partial erasure. An editing method in which an arbitrary screen of a movie object is extracted as a still image and displayed simultaneously with the audio object. You can fry.

[0171]

The effects of the present invention as described above are summarized as follows.

[0172] 1. By providing break information of audio tracks in a PGC (Program Chain) Information indicating a reproduction procedure in management information related to audio information, the management information has the same data structure and data structure hierarchy (PGC / (Program) / hierarchical structure of cells).

As a result, high compatibility with the existing Video Recording Standard can be ensured, and mutual entry during reproduction between video information (movie object) and audio information becomes possible. In addition, since the break information of the audio track is recorded in the management information, recording, reproduction, and editing processing per audio track specific to the audio information can be performed very easily.

2. The program in the original program chain information 144, which is management information on the original track, is made to correspond to the original track, and the program information 31 which is an information recording area for this program.
By recording “text information on audio track”, “representative image indicating audio track content”, “still image display mode”, “erase prohibition flag”, etc. unique to the audio track in Information can be managed in detail, and recording, reproduction, and editing processing for each audio track can be performed very easily.

3. Cell information 16 in the user-defined PGC information table 145, which is management information relating to the play list
Track head entry points 171 to 173 indicating break information of audio tracks for 4 to 169
"Text information on audio track", "representative image indicating audio track contents", "still image display mode", "erase prohibition flag"
By giving information specific to various audio tracks in the track head entry points 171 to 173, information of each audio track can be finely managed.
Recording, reproduction, and editing processing for each audio track can be performed very easily.

4. When the user designates still images to be displayed simultaneously during audio track playback, the display timing of each still image during audio information playback is automatically calculated from the playback time of the audio track and the set number of still images, and managed. By automatically recording the information, the display time of the still image can be set very easily without burdening the user.

5. The original list and the playlist are displayed on the screen at the same time (applicable to video recording as well as audio recording), so that the user can easily create the playlist.

6. When a part of the original track in the original list is collected to create a new track on the playlist, or when the inside of the original track is partially erased, A) All the still images to be displayed when the original track is reproduced It is used for a still image displayed when a new track is reproduced on the playlist, or all still images displayed before partial erasure are displayed after partial erasure.

B] Of the still images displayed during the reproduction of the original track, only the still images within a specific range are used as the still images displayed during the reproduction of a new track on the playlist, or are displayed within the partial deletion range. The displayed still image is not displayed after partial erasure.

If the processing to be selected is different depending on the editing machine (information recording / reproducing apparatus), the user is confused and the processing of (A) or (B) is performed at a place where the user does not recognize. Edit machine (information recording / reproducing device)
The user feels uncomfortable when it is performed automatically in the room.

By displaying in a display mode 7 information for determining which of (A) and (B) to perform on the screen where the user creates a playlist, a method of setting a still image for a new track can be determined. The user can understand and do not feel discomfort, and can set a fixed still image regardless of the model of the editing machine (information recording / reproducing device).

7. The arbitrary screen of the movie object is extracted as a still image and registered in the still picture AV file information table 142 as a still image that can be displayed simultaneously with the audio object, so that the arbitrary screen of the movie object can be extracted simultaneously with the audio information. It can be used as a still image to be displayed. At the same time, since the still image information can be collectively recorded in one place, the access to the still image can be speeded up, and the still image and the audio information can be reproduced continuously without interruption.

8. Further, in the present invention, the designation information of the representative image indicating the track content is designated in the management information in the management information, and the designation information of the representative image is the same as the designation information of the still image displayed at the time of reproducing the audio track. Is provided separately. For this reason, an arbitrary still image in a VOB group located in a different place other than the video object (VOB) group in which the still image held when reproducing the audio track is recorded can be set as the representative image, and the degree of freedom can be increased. be able to.

9. By providing the display range information of the representative audio indicating the content of the audio track in the area where the unique information for each audio track is recorded, the user does not listen to all the audio tracks, but wants to check the audio displayed on the display screen shown in FIG. Just specify the track,
You can see if it's the audio track you want to hear,
The searchability to the audio track of the user is greatly improved.
