DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention records various types of data such as video (moving images), still images, and audio, and control data for selecting and reproducing any one of these data. and of the digital recording medium such as a CD-ROM is
The present invention relates to an information arranging method and a reproducing apparatus, and more specifically, to an improvement in a data recording and reproducing method.

[0002]

2. Description of the Related Art A signal (or a compressed signal) of information such as a video, a still image, and an audio, and a signal or a computer program for controlling the information are recorded on a digital recording medium such as a CD-ROM. Has developed a digital recording medium that allows a program to proceed in an interactive manner and a reproducing apparatus therefor, and some of them have been put to practical use (for example, see Japanese Patent Application Laid-Open No. 3-290867).

[0003] However, such interactive media is
Because it takes time to produce software such as video, the price of the medium is high, the number of titles is small, and the playback device is also expensive due to complicated operations.
It is not always satisfactory and there is a demand for improvement.

By the way, when examining the contents of such interactive media, most of them pause playback (pause) when the menu screen is displayed. The user is displayed on the menu screen. It can be seen that the procedure of selecting one of the several contents, jumping to the position of the information of the selected menu and reproducing, and displaying the menu screen again after the end is repeated. Therefore, by recording the position information of the pause and the jump destination in the form of a list together with the compressed signals of various menus, it is easy to produce software, and the reproducing apparatus can simply repeat the pause / jump according to the contents of the list. , Interactive selection reproduction can be easily realized.

[0005] There are the following two conventional techniques for realizing such an interactive selective reproduction operation. The first method is mainly used for video discs represented by LDs and VHDs, and records a special signal in which various kinds of information such as video, still image, and sound (hereinafter, referred to as “menu information”) are recorded. The press-in recording is made in advance in the area in which it is set. And
During playback, these special signals are detected and paused at that position. Naturally, when paused, a menu screen showing the next destination is displayed. When the user operates a remote control key or a key attached to the player to select one of the menus, the user jumps to a recording position of the menu information and reproduces the menu information.

The second method is a method of realizing interactive selection and reproduction by a CPU program, and is employed in computer-related equipment and CD-I systems. According to this, the control program is recorded in an area of the medium different from the recording area of the menu information. In particular, in a computer-related device, the control program may be recorded on another medium. In the playback device, the control program is first read, and thereafter all operations proceed under the control of the CPU. In any case, according to this method, it is possible to realize a complicated and advanced interactive selection and reproduction operation.

[0007]

However, such a conventional technique has the following disadvantages. First, the first
In the method of (1), since a special signal for pause is recorded in an area where menu information is recorded, it may not be possible to easily change the pause position. In particular,
Changing the jump destination involves changing the menu screen, which requires careful attention when creating software, and is time-consuming.

[0008] In the second method, high-level interactive selection reproduction can be realized, but on the other hand, development of a control program requires a great deal of time and software production costs increase. Also,
There are inconveniences such as restrictions on the CPU and OS of the playback apparatus, difficulty in maintaining compatibility, and an increase in cost.

The present invention focuses on these points.
In addition to simplifying the production of software that realizes interactive menu information selection and playback operations, we aim to improve productivity and
A digital signal recording medium with a high degree of design freedom that can easily change the program progress (scenario)
It is an object of the present invention to provide an information arrangement method and a reproducing apparatus therefor.

EXAMPLES The following digital signal recording medium according to the present invention
An embodiment of an information arranging method and its reproducing apparatus will be described with reference to the accompanying drawings. <Outline of Embodiment> First, an outline of the following embodiment will be described to facilitate understanding. FIG. 1 shows an example of an information recording mode on an optical disc. According to this embodiment, a group of control information tables such as pause or pause / jump, which is data for dialog control, is recorded on a predetermined track of the optical disc 10, for example, the outermost track 12. Then, a menu information group including specific video and audio contents of each menu and a menu screen are recorded on the inner track 14 in a predetermined order.

When such an optical disc is set in the reproducing apparatus, the control information table group of the outermost track 12 is read out to the memory of the control means such as the CPU, and a menu is displayed on the display device. That is, as the initial operation, the image information of the main menu screen in the inner track 14 is reproduced and displayed. The user selects a desired one while viewing the menu screen.

Then, on the playback device side,
The corresponding menu information in the inner track 14 is reproduced. On the other hand, the control information table group read from the outermost track 12 to the memory is referred to, and the pause position of the menu information being reproduced is obtained. Then, when the reproduction is performed up to the pause position, the reproduction operation is stopped, a menu screen is displayed, and a pause state is set.

The user refers to this menu screen and selects a desired menu again. Thereafter, the above-described operation is repeated. After selecting any menu,
The following detailed menu may be displayed.

As described above, the control information is stored in the outermost track 12 and the menu information including the menu screen and the menu contents are stored in the inner track 14 separately from each other. Therefore, it is not necessary to add a separate signal such as a pause signal when recording the menu information group. As a result, it is possible to improve the degree of freedom in producing and changing interactive software and media.

<Outline of CD-ROM Disk and Search Method> Next, in order to facilitate understanding of the embodiment, an outline of a CD-ROM disk as a typical optical disk and a search method thereof will be described. FIG. 2A shows a CD-RO
An overview of the M disk is shown. In the figure, a main information channel records a group of menu information such as, for example, compressed video, still images, and audio. As is well known, digitized video, still images, and the like require an extremely large code amount, and thus cannot be directly recorded on a CD-ROM.

Therefore, when recording information such as a video and a still image on a CD-ROM, generally, the information is compressed and then recorded using a high-efficiency encoding technique.
Further, by performing the information compression in this manner, it becomes possible to store a large number of menu information groups on the CD-ROM.
The main information channel employs a sector structure, and also records a sector address that accurately indicates the recording position of the main information.

On the other hand, the sub information channel has a track number, an index number obtained by further subdividing the track according to the contents recorded in the main information channel, and a resolution having the same cycle as the sector of the main information channel described above. Information such as time code information (commonly called A-Time) is recorded.

Next, a method of searching (accessing) each piece of information recorded on such a CD-ROM will be described. The first method is a method adopted in a music CD that is widely used, and uses only a sub information channel. According to this method, using the track number, index number, A-Time, and the like recorded on the sub information channel, the start of each information recorded on the main information channel is performed. This first method generally involves P
This is called a Q search method.

In the second method, after locating the approximate main information by the first method, the accurate locating of the main information is performed by reading the sector address recorded in the main information channel. Is the way. This second method is generally called a ROM search method.

The first method can be realized by simple hardware, that is, a low-cost device, but has a disadvantage that the accuracy of finding the main information is not very good. However, it is enough to find the start of information such as music and images (when compression processing is not performed). The second method is a method mainly when a CD-ROM is used as a computer peripheral device, and can accurately locate the main information as instructed, but at a slightly higher cost.

In the following embodiment, in consideration of the above, in the control information table group, not only the sector address accurately indicating the recording position of the main information, but also the track recorded on the sub information channel. Information for PQ search such as a number and an index number is also recorded at the same time. Therefore, the present invention can be applied to a playback apparatus of any search method, and is convenient in terms of compatibility.

<First Embodiment> First, FIGS. 1 and 2A
The first embodiment of the present invention will be described with reference to FIGS. FIG. 3A shows the optical disk 1 of FIG.
An example of a menu (displayed by M) information group recorded on the inner track 0 is shown in FIG. 2B. In FIG. 2B, a control information table (denoted by T) recorded on the outermost track 12 is shown. An example) group is shown.

This example is an example of a travel guide, and information such as images and sounds of the travel guide for each region such as Hokkaido and Tohoku is
It is stored as a menu information group together with those menu screens. Menu screen information is added to the end of information on menu contents such as Hokkaido and Tohoku, respectively. Then, the optical disk 1 of each of these menu information is stored.
Pause position information corresponding to the recording end position on the inner track 0 is separately organized as a table group as shown in FIG.

For example, menu 0 is a main menu screen, and this image information is recorded on the inner track 1 of the optical disc 10.
4 is stored. The end position when the main menu screen is reproduced is stored in the table 0 as the pause position of the menu 0. Similarly, the menu 1 is a travel guide of Hokkaido, and information such as an image of this guide is stored in the inner track 14 of the optical disc 10. The end position when the Hokkaido travel guide and the added menu screen are reproduced is stored in the table 1 as the pause position of the menu 1. The same applies to menu 2 and the following.

FIG. 4 shows an example of a table constituting such a pause position information table group. In the figure, one table has a configuration of 7 bytes of byte numbers 1 to 7.

Of these, serial numbers of a plurality of pause position information tables are written in the first two bytes of byte numbers 1 and 2. This serial number is not absolutely necessary data, but it is useful if it is recorded. For example, position information data of a PQ search or a ROM search is a BCD (Binary Coded Decima).
l), the hexadecimal "F" (10
In hexadecimal display, “15” does not exist in the position information data. Therefore, by recording this "F" in byte numbers 1 and 2, it can be used as a table delimiter. Further, if "FFFF" is recorded in these byte numbers 1 and 2, it can be used as the end of the table group. An example of an effective use method of this serial number will be described in a third embodiment described later.

Next, a track number indicating a pause position is recorded in byte number 3, and an index number indicating a pause position is recorded in byte number 4. That is, the information of these byte numbers 3 and 4 is the pause position information of the PQ search method described above, and when the reproduction of the menu information of the corresponding main information channel is completed, the track and index designated here are set. Is set to a pause state at a position corresponding to.

Next, in byte number 5, data of “minute” in the sector address information is recorded.
Indicates data of "second", and byte number 7 indicates data of "frame". That is,
The information of these byte numbers 5, 6, and 7 is stored in the R
The information is sector address information of the OM search method. When the reproduction of the menu information of the corresponding main information channel is completed, the reproducing apparatus is set in a pause state at a position corresponding to the sector address specified here. . It is mainly used in a ROM search type playback device.

In the ROM search method, since the sector address recorded in the main information channel is directly referred to, the pause can be accurately made at the position of the information written in the table. In the figure, "x1" is the first digit of information, "x10" is the second digit of information, "x100".
Indicates the third digit of the information. Next, the operation of the first embodiment will be described with reference to FIGS. FIG.
Shows a flowchart showing the order of operations, and FIG. 6 shows an example of a menu screen.

The user sets the optical disk 10 on which information is recorded as described above in a reproducing apparatus (described later) (FIG. 5, step S1), and starts a reproducing operation by pressing, for example, a "PLAY" button (step S2). ). Then
On the playback device side, the outermost track 12 of the optical disk 10 is read from the outermost track 12 of FIG.
The pause position information table group (B) is loaded into the memory of the CPU, and the information of the menu 0, that is, the image information of the main menu screen, is read from the inner track 14.

At the same time, the pause position information of the menu 0 is obtained by referring to Table 0 of the pause position information table group read into the memory. When the head during the reproducing operation reaches the pause position, the main menu screen is displayed, and the head stops at the position and enters a pause state (step S3).

FIG. 6 shows an example of the main menu screen, which shows the titles of the menus and the jump information which is the writing position of the information contents. For example, information on Hokkaido is recorded from the position where the track number is “03”, the index number is “01”, and the address is “02:34:56”. The information of the Tohoku region is recorded from the position where the track number is “03”, the index number is “02”, and the address is “04:56:70”. The same applies to other menus.

The user selects and instructs the playback apparatus to select jump position information of a desired menu, that is, track number and index number, or address information by an appropriate input means such as a remote controller or a keyboard (step S).
4). Then, the reproducing device moves the head to the designated jump position and reproduces the selected menu information. At the same time, the pause position information of the corresponding menu information is obtained from the pause position information table group (step S).
5).

For example, when the user wants to see the travel information in the Tohoku region, the user must enter the track number “03” and the index number “02” or the address “04:56:70” as the jump information in the Tohoku region (FIG. Refer to). Then, on the playback device side, a PQ search is performed from the information of the track number “03” and the index number “02”,
Alternatively, from the information of the address “04:56:70”, the RO
The M search is performed, and the head jumps to the recording start position of the menu information in the Tohoku region. Then, the menu information is reproduced (steps S6, S7).

On the other hand, with reference to the pause position information table group shown in FIG. 3B, the pause position of menu 2 (see FIG. 3A), which is travel information of the Tohoku region, is obtained from table 2. When the head during the reproduction operation reaches the pause position (step S6), the head stops at that position to put it into a pause state, and the still image of the menu screen added to the end of the travel information of the Tohoku region Is displayed (step S8). By performing the above operations repeatedly, the user can obtain desired travel guidance in a desired order.
Alternatively, travel guidance for the same region can be repeatedly reproduced in an interactive manner.

<Second Embodiment> Next, a second embodiment of the present invention will be described with reference to FIGS. In the first embodiment, a relatively simple interactive program having only one menu screen is used. However, in the second embodiment, when a certain menu is selected, a complicated menu is displayed such that the next menu screen is displayed. This is an example of a simple interactive program. But,
According to the present embodiment, such a complicated interactive format can be easily realized.

FIG. 7A shows a menu information group in this embodiment, and FIG. 7B shows a pause position information table group in this embodiment. In this example, the travel information of Kanto Koshinetsu is further divided into three menus 31 to 33 of South Kanto, North Kanto, and Koshinetsu as shown in FIG. They are stored in the tables 31 to 33 as shown in FIG. Further, in the present embodiment, image information of the sub-menu screen as shown in FIG. 8 is stored in the recording portion of the menu 3 corresponding to “Travel information of Kanto Koshinetsu” in the first embodiment.

Next, the operation of the present embodiment will be described. First, the menu screen of FIG. 6 is displayed in the same manner as in the first embodiment. Here, it is assumed that the user selects the third “Kanto. Koshinetsu region” and instructs the jump information such as the track number 04. On the reproducing apparatus side, the head is moved to the jump position, and the information of the menu 3, that is, the sub-menu screen shown in FIG. 8 is reproduced. And
The head stops at the pause position in Table 3 of the pause position information table group in FIG. 7B and enters a pause state.

Next, the user selects a desired menu from the sub-menu screen of FIG. For example, if jump information on the northern Kanto area is input, the head moves to the jump position and travel information on the northern Kanto area is reproduced. On the other hand, the pause position information table group of FIG. 7B is referred to, and the pause position of the table 32 corresponding to the northern Kanto area is obtained.
Then, when the head reaches the pause position, the head stops and, for example, the main menu screen of FIG. 6 is displayed again to enter the pause state.

At this time, the sub-menu screen of FIG. 8 is displayed, and “4, main menu AB CD EF: GH: IJ” (where A to
J can return to the main menu from the sub-menu by including the jump information of the main menu screen). Either one can be easily set by a menu screen added after the contents of the menus 31 to 33.

In the second embodiment, the menu has two stages, but may have a plurality of stages. As described above, according to the present embodiment, a menu screen of a plurality of stages is prepared, and a table indicating the pause position of the menu information of each stage is prepared in the pause position information table group. An interactive selection operation using a menu extending over stages can be easily realized.

Third Embodiment Next, a third embodiment of the present invention will be described with reference to FIGS. In this example, as shown in FIG. 9A, the control information is a pause / jump position information table group, and the jump position information is also stored in the table. The key number designated by the user is stored together with the jump position. The menu information group is shown in FIG.
Is the same as that shown in FIG.

FIG. 9B shows the configuration of such a pause / jump position information table, and FIG. 10 shows an example thereof. In these figures, 1
One table is composed of pause position information of a corresponding menu and a plurality of jump position information indicating a jump position of each menu displayed in a pause state at this position. In the case of this example, eight jump position information blocks corresponding to the number of menus shown in FIG. 11 are included. The example of FIG. 10 shows the pause position of the main menu screen which is the table 0, that is, the menu 0, and the menu 1, 2, 3, 8 portion of the jump position information block of each menu.

In order, the event numbers of byte numbers 1 and 2 are assigned in the order of tables 0 to 8. By referring to these event numbers, the pause position after jumping and performing the reproducing operation is obtained. The table in which the information is stored can be easily found.
Next, regarding the pause position information of byte numbers 3 to 7,
This is exactly the same as in FIG.

Next, in this example, the position information of eight jump destinations is written, and that fact is recorded in the byte number 8. That is, by referring to the byte number 8, it is possible to determine how many blocks of jump information are written below. In this example, since there are eight jump position information items corresponding to “Hokkaido” in menu 1 to “others” in menu 8, the data of byte number 8 is “8” (decimal display). With this data, the playback device can know in advance the number of jump positions and the total number of bytes included in the current table without searching for the event number at the head of the next table.

Next, the jump position information block will be described. In the first byte, the key number is written. This byte is, for example, “A1” in hexadecimal notation,
“A2”, “A3”,... The first digit “A” indicates the start or break of the jump position information block. The next digit is the key number itself, which directly corresponds to, for example, a menu number designated by the user using a remote controller or a keyboard.

Next, the PQ search jump position information is written in the next two bytes of the key number byte, and the ROM search jump position information is written in the next three bytes. The track number and index number are included in the jump position information for PQ search,
The point that the minute, second, and frame sector addresses are included in the ROM search jump position information is the same as the pause position information. Then, in the next two bytes of the jump position information, the event number of the table in which the pause position of the menu reproduced by jumping is written,
That is, the event number of the table referred to after the jump is written.

More specifically, the menu display of this embodiment is as shown in FIG. 11, for example, and the menu number of the Hokkaido travel guide is "1". Therefore, the key number "A
1 "jump position information block (byte number 9-1
In the byte numbers 10 to 14 in 6), jump position information indicating the head position of the recording area of the menu contents of Hokkaido is written. Then, the event numbers of the table in which the pause position information when the contents of the Hokkaido menu are reproduced are written in byte numbers 15 and 16.

Similarly, in byte numbers 17 to 24,
The jump position information of the Tohoku region corresponding to the key number “A2” and the event number of the table in which the pause position information is written are written. In the byte numbers 25 to 32, jump position information of the Kanto / Koshinetsu region corresponding to the key number A3 and an event number of a table in which the pause position information is written are written. Hereinafter, the same applies to the jump position information blocks of the fourth to eighth menus.

Next, the operation of the third embodiment will be described. In this example, since the jump position information is written in the control table group, the menu screen is as shown in FIG. 11, and the jump position information is not displayed.
Selection of a menu is performed only by inputting the number.

As in the first embodiment, the pause / jump position information table group shown in FIGS. 9 and 10 is loaded into the memory on the playback device side, and the menu screen shown in FIG. 11 is displayed. At the pause position indicated by 0, a pause state is set.

In this state, the user specifies a desired menu number with a remote controller, a keyboard, or the like. Then, the reproducing device refers to the jump position information corresponding to the designated key number in table 0, moves the head to that position, and performs the reproducing operation of the selected menu. At the same time, the event number of the jump position information block of the key number is referred to, and the processing moves to the corresponding table. Then, the pause information in the table is referred to, and when the head reaches the corresponding pause position, the head is stopped, a menu screen is displayed, and a pause state is set. Thereafter, the same interactive operation is repeated.

Next, a specific description will be given with reference to FIG. For example, it is assumed that the user has designated "2" as a key number in order to view travel information for Tohoku. Then, on the playback device side, the track number “03”, which is the PQ search jump information of the key number “A2”, and the index number “0”
2 ", ROM search jump information" 04: 56: 7
"0" is obtained from table 0, the head moves to this position, and the information on the Tohoku trip is reproduced. The event number of the jump information block with the key number “A2” is “0”.
2 ”, the table 2 of the event number“ 02 ”is referred to.

When the pause position information of the table 2 is obtained, a menu screen is displayed at that position, and a pause state is set. Hereinafter, the same applies when another menu is selected. As described above, according to the third embodiment, since the jump information is included in the control table, the user need only indicate the menu number, and the operation becomes very simple.

The third embodiment may be an interactive system having a plurality of menu screens as in the second embodiment. In this case, the image information of the sub-menu screen shown in FIG. 8 is recorded at the position of the menu information in the Kanto and Koshinetsu regions as shown in FIG. 7A, and each menu of FIG. To write the jump position information. Then, a table including pause position information and jump position information corresponding to each menu in FIG. 8 may be prepared as shown in FIG. 7B.

<Fourth Embodiment> Next, a fourth embodiment will be described with reference to FIG. As mentioned above,
The CD-ROM is composed of a main information channel and a sub information channel, and a track number and an index number of the sub information channel are recorded corresponding to the contents of the main information channel. However, since the channels are separated, a slight shift occurs in the data acquisition between the two channels. This shift between the two channels is generally called skew.

The presence of this skew causes the PQ
In a search-type player, a problem may occur in the position of a pause or a jump destination with respect to main information. That is, when the PQ search is performed, data at the beginning or end of the main information may be missing.

In particular, when compressed image or audio information is recorded as main information, even a slight loss of data is reproduced with a large obstacle. Therefore, FIG.
As shown in (B), some dummy areas (dummy sectors) are added before and after the compressed menu information. Then, the position of the pause or the jump destination is determined including the dummy area. In this way, the missing data due to the skew is dummy data, so that the data at the beginning or end of the main information is prevented from being lost.

<Fifth Embodiment> Next, a fifth embodiment will be described with reference to FIG. This embodiment is an embodiment of the optical disc reproducing apparatus 40. In the figure, the output side of a CD mechanical drive 20 for driving the optical disk 10 is connected to a CD decoder 22, and the output side is connected to a CD-ROM decoder 24. CD-R
The video signal output side of the OM decoder 24 is connected to a video playback device 28 such as a TV monitor via a compressed video decoder 26, and the audio signal output side is connected to a video playback device 30 via a compressed audio decoder 30 such as an amplifier or a speaker. 32.

The control data output side of the CD-ROM decoder 24 is connected to the RAM 34 and the CPU 36, respectively, and the CPU 36 is provided with an instruction device 38 such as a key and a remote controller. The control output side of the CPU 36 is connected to the CD mechanical drive 20.

Of the above components, the CD mechanical drive 20
Includes a mechanical system for driving the optical disk 10, an optical pickup, and the like. The CD decoder 22
This is a music CD decoder that performs processing such as error correction on a signal input from the pickup side of the D mechanical drive 20.

The CD-ROM decoder 24 generally has an R
It is called an OM decoder, and has a function of decoding a digital signal supplied from the CD decoder 22, determining the type of data, and distributing the data to various decoders connected to the subsequent stage. More specifically, video data such as video and still images are transferred and output to the compressed video decoder 26, and audio data is transferred and output to the compressed audio decoder 30. Further, the data of the control table group including the information indicating the pause position and the jump position described above is transferred to the RAM 34 and output.

Next, the video reproducing device 28 is for displaying the video signal supplied from the compressed video decoder 26. The audio reproducing device 32 is for reproducing the audio signal supplied from the compressed audio decoder 30. Further, the CPU 36 includes a pointing device 38.
With reference to the user's instruction contents and the table group in the RAM 34, operation commands such as reproduction, pause, and jump are issued.

Next, the operation of this embodiment will be described by taking the case of the third embodiment as an example. When the optical disk 10 is set and there is a reproduction instruction from the user, first, the reproduction is driven by the CD mechanical drive 20 and the disk is checked by the CPU 36. That is, it is determined whether the pause / jump position information table group shown in FIGS. 9 and 10 is recorded, and if it is recorded, the data of the table group is read into the RAM 34.

Then, as an initial operation, the CPU 36 instructs the CD mechanical drive 20 to reproduce the menu screen information, and refers to the pause position information written in the table of the first event number in the table group. The image information of the menu screen read from the optical disk 10 is supplied to the video reproducing device 28 via the compressed video decoder 26. Then, the menu screen shown in FIG. 11 is displayed. Then, when the pause position is reached, the CPU 36 enters a pause state in response to an instruction from the CPU 36 and waits for an instruction input from the user.

Here, it is assumed that the user erroneously designates a menu number which is not displayed on the menu screen. For example, if "9" is input by the instruction device 38, the CPU 36 determines that the input is invalid and waits for the next instruction.

Next, for example, if the number “3” is designated, the CPU 36 sets the jump position written in the key number “A3” of the jump position information block of the table 0 in the table group stored in the RAM 34. A command is issued to the CD mechanical drive 20 so as to jump to and perform playback. As a result, the reproduction of the travel information on “Kanto Koshinetsu” is started. That is, of the travel information of Kanto Koshinetsu, video information is reproduced by the video reproduction device 28, and audio information is reproduced by the audio reproduction device 32.
Will be played back.

On the other hand, in the CPU 36, the key number "A3"
The table 3 of the event number corresponding to the jump position is referred to, and the pause position information written in the table is detected. When the pause position matches the disc reproduction position, a pause state is set. At this time, the menu is displayed again on the screen. In this manner, the operations of pause, user key input, jump, playback, menu display, pause,...
Interactive sequence control is realized.

<Other Embodiments> The present invention is not limited to the above-described embodiments, but includes, for example, the following. (1) In the above embodiment, the interactive control table group is stored in the outermost track of the optical disc, and the contents of each menu and the information of the menu screen are stored in the inner track.
The storage positions are arbitrary and may be set as appropriate. (2) The data format of the control table can be variously changed.

(3) In the above embodiment, the case of travel guidance has been described, but the present invention can be applied to various kinds of software. Also,
The number of menus may be increased or decreased as needed, and the type of menu may be set as appropriate, for example, only video signals. (4) When an optical disk such as a CD-ROM is used as a medium, a large capacity allows a large number of menus to be stored. However, in addition to an optical disk, a magnetic disk may be used.

(5) The design of the reproducing apparatus can be variously changed so as to achieve the same effect. For example, if a table group for dialog control is not recorded on the medium,
By detecting this, a normal reproduction operation, for example, a reproduction operation as a music CD is ensured.

Dialogue like a tree structure (tree structure) with branches
The format can be handled. (2) The change of the program progress (scenario) can be performed by a very simple correction operation of rewriting the position information data in the list recorded on the digital signal recording medium.

(3) Since data considering both the PQ search method and the ROM address search method are written in the list recorded on the digital signal recording medium, the degree of freedom in designing the reproduction apparatus is improved. . (4) Menu contents in the digital signal recording medium , or
Pause position information stored separately from the menu screen
If the If writing is written into a memory in the reproducing apparatus jumps position information during reproduction, it is possible to control the digital signal recording medium mounted on the reproduction apparatus interactively, simply only to simplify the key input operation In addition, runaway of program progress due to erroneous operation of key input can be prevented. Ma
The memory in the playback device stores pause position information and jumps.
Reduced memory capacity to store only location information
it can. (5) digital signal recording medium by the pause position information and di catcher down <br/> flop position are decision has been recorded,
Normal reproduction becomes possible when a digital signal recording medium in which position information of a pause and a jump destination is not recorded is mounted on the apparatus.
