Embodiments of the present invention will be described below in detail with reference to the drawings. Here, the video data recording medium and the video data reproducing device according to the present embodiment will be described with reference to an example where the present invention is applied to a DVD and a DVD player. Therefore, the DVD corresponds to the video data recording medium according to the present embodiment, and the DVD player and its peripheral devices correspond to the video data reproducing device according to the present embodiment.

First, the data structure of the DVD format will be briefly described with reference to FIG. In a DVD, a recorded multiplexed audio (audio) / video (video) data stream is divided into several logical spaces (domains) and managed. The type of logical space is
There are four types as follows, and the DVD format is composed of these combinations.

First play domain (First play domain)
Play Domain; hereinafter, referred to as FP DOM. 1) This is the first space to be accessed when a disc (DVD) is loaded, and only one space is allowed.

[0015] Video Manager Menu Domain (hereinafter referred to as VMGM D)
Recorded as OM. 2) This is mainly a space in which a title menu is described, and a plurality of spaces can exist. I'll explain in detail later,
In the present embodiment, a trailer, which is an accompanying image reproduced along with the main video, is arranged in this space.

[0016] Video title set menu
Domain (Video Title Set Menu Domain; hereafter, VT)
Notated as SM DOM. 3) This is where the root menu, audio menu, subtitle (sub-picture) menu, chapter menu, and angle menu of the DVD menu specified in the DVD format except for the title menu are placed. It is a space that can be inserted, and there can be multiple spaces.

Title Domain (hereinafter referred to as TT DOM) 4 This is a space in which the main part of the DVD is placed, and video data, audio data, subtitle (sub-picture) data, etc. are multiplexed. A movie or video clip itself. There can be more than one of these.

In the DVD format, these domains are divided into groups, and the following spaces are used.
Is defined. However, this space is a concept defined on the format, and does not relate to the playback function on the DVD player.

VMG space 5 This is composed of one or more VMGM DOM2 and one FP DOM1.

VTS space 6 This is composed of one or more VTSM DOM3 and one or more TT DOM4. When there are a plurality of titles, there are a plurality of TT DOM4. It should be noted that a plurality of VTS spaces 6 themselves can exist, but they are not relevant to the present invention, and thus description thereof is omitted.

Menu space 7 This is a collection of one or more VMGM DOM2 and one or more VTSMDOM3. Menu space 7 contains language units (Langua
ge Unit; hereinafter, referred to as LU. ) 8 group, which is a VMGM expressed in the same language.
DOM2 and VTSM DOM3 are linked. FIG.
Then, four types of LUs, that is, LU # 1, LU # 2,
This shows a case where LU # 3 and LU # 4 are present,
It means that there is a menu expressed in four languages.

As described above, the LN 8 exists in the menu space 7. Note that a system space 9 is a space that includes the menu space 7, but the system space 9 is not related to the present invention, and thus the description thereof is omitted.

As described above, the domain has a characteristic of "one concept and a unit of reproduction". DV
In the D format, the unit of reproduction is represented by reproduction control data called a Program Chain (hereinafter referred to as PGC). In such a sense, as shown in FIG.
It can be considered as a collection of C11. Note that, specifically, although a certain area of the disk is divided into a certain domain, the PGC relating to the domain is not physically located there.

In a DVD, actually multiplexed video or audio data is called a video object (hereinafter referred to as VOB). A VOB is composed of a series of meaningful multiplexed video and audio data, such as a movie title, an audio menu, a chapter menu, and the like. It is defined as multiplexed data that has a significant meaning in reproducing the data.

Therefore, a single disk usually has a plurality of VOB clusters. As shown in FIG. 3, each VOB 12 has a VOB identification number (hereinafter referred to as a VOB ID number). Alternatively, it is simply referred to as a VOB number.) (ID # 1 in FIG. 3). The VOB is further divided into units called cells (hereinafter, referred to as CELLs) 13, and each CELL 13 is assigned a CELL identification number (hereinafter, a CELL ID number, or simply a CELL ID number) in ascending order from 1.
Described as L number. ) (ID # 1 to ID # 6 in FIG. 3). CELLs 13 are not mechanically separated, but are defined as meaningful chunks, similar to the VOB idea. For example, in the case of a movie title, it corresponds to the break of each chapter, and when a certain menu is composed of a plurality of pages, it corresponds to each display page.

Here, the description returns to the PGC 11. PGC
Reference numeral 11 denotes a pre-command (hereinafter referred to as P
Recorded as RE CMD. ) 14, VOB identification unit (hereinafter, V
Recorded as OBID. ) 15 and post command (hereinafter, referred to as
It is written as POST CMD. ) 16.
Among them, the VOB ID 15 is composed of a set of the above-mentioned VOB ID number and the start address on the disk where the corresponding VOB is recorded. A plurality of VOB IDs 15 can be connected.

The VOB ID 15 further includes a series of CELL identification units (hereinafter, referred to as CELL ID) 17. CELL ID 17 is VOB ID
As in the case of No. 15, it is composed of a combination of the ID number of each cell in the VOB (in FIG. 4, it is denoted by #n) and the head address on the disk where the cell is recorded.

The DVD player has the VOB ID 15
By sequentially tracing the information of CELL ID 17 from the beginning, the address where the entity of the multiplexed data to be reproduced is recorded is known, and the data is actually reproduced. For convenience, this operation will be referred to as PGC reproduction. The PRE CMD 14 is a navigation command (Navigation Command) executed before the reproduction of the PGC.
mand), and POST CMD16 is PGC
Is a navigation command executed after the playback of the. The navigation commands will be described later.

Looking at the above, the domain 10 is composed of a certain PGC 11, the actual multiplexed data (VOB 12) corresponding to the PGC 11, and the VOB attached to the PGC 11.
It can be considered that it is composed of a set with an ID number. Actually, the domain 10 contains more data, but it is not related to the present invention, so that the description is omitted.

Next, the navigation command will be described. In the DVD format, a unique programming language called a navigation command is prepared to control a reproduction method on a DVD player. The program described by the navigation command is recorded on a disc together with video and audio data, and the DVD player reproduces the video and audio data according to the program.

In a DVD, a plurality of audio channels can be multiplexed. For example, a program using a navigation command specifies which of a plurality of audios to select, and a specific program called a chapter. Jump directly to the cue point (in the case of a movie, the beginning of a highlight scene or a break in the story; a point that represents a break in a song like a track on a CD (compact disc)). Used to start playback. This example is the simplest of a navigation command program, but more complex operations are possible.

For example, at the end of playback of a chapter,
A still image asking a question to the viewer appears, and depending on the viewer's answer to the question, an interactive (interactive) work (software) that determines the next chapter to jump to and play back , This navigation
This is enabled by a program using commands. This example is used in works called multi-story / multi-ending (works with high game-like elements in which there is an option such as A or B for each scene break, and the result of the selection determines the next scene). It is a technique that is performed.

Next, the LU will be further described. First, a basic case in the LU menu will be described. FIG. 5 shows LU and P in VTSM DOM3.
It shows the relationship between the structure of GC and VOB. In this example, it is assumed that the types of languages are Japanese, English, French, and German in all four languages. FIG. 5 shows VTSM DOM3
There are four menus, root menu, audio menu, subtitle menu, and chapter menu, and each menu is
The case where the language is expressed in four languages of Japanese, English, French and German is shown.

First, as a matter of course, there are only 16 VOBs, which are the actual menus to be displayed, ie, the type of the menu × the number of languages, that is, 16. On the other hand, since there are PGCs corresponding to the number of menus, a total of four types are required, but since these must be prepared for four languages, one PGC is also required.
There will be six types. Each PGC describes which VOB corresponds to each PGC.

In the example shown in FIG. 5, the PGC of each menu
Are grouped into PGCs # 1 to # 4 for each language and given LU numbers LU # 1 to # 4.
1 to # 4 are collectively referred to as VTSM PGC information and entry search data (Entry
Search Data) is recorded on the disc as part of an area called “Search Data”. Here, each LU corresponds to the VTSM DOM of the menu for each language.

In the example of FIG. 5, LUs # 1 to # 4
Japanese VTSM DOM and English VTSM D respectively
OM, French VTSM DOM, German VTSM DOM are supported. PGCs # 1 to # 4 of the Japanese VTSM DOM (LU # 1) correspond to VOBs # 1 to # 4, respectively, and VOBs # 1 to # 4 correspond to Japanese roots and
It is a menu, audio menu, subtitle menu, and chapter menu. English VTSM DOM
PGCs # 1 to # 4 of (LU # 2) are VOBs respectively.
Corresponding to # 5 to # 8, VOBs # 5 to # 8 are entities of an English root menu, audio menu, subtitle menu, and chapter menu, respectively. French VTS
PGCs # 1 to # 4 of M DOM (LU # 3) correspond to VOBs # 9 to # 12, respectively, and VOBs # 9 to # 12, respectively.
Are the entities of the French root menu, audio menu, subtitle menu, and chapter menu, respectively. PGC # 1 of German VTSM DOM (LU # 4)
# 4 corresponds to VOBs # 13 to # 16, respectively.
OB # 13 to # 16 are respectively a German root menu, an audio menu, a subtitle menu, a chapter
The substance of the menu.

First, the DVD player knows the number of languages in all by looking at the above-described entry search data. The user can set one of the languages as a preset state using a remote control device, a switch of a DVD player, or the like. At this stage, in the example shown in FIG. 5, only four of the 16 PGCs corresponding to a certain language are specified. After that, each menu call command is issued by the remote control device of the DVD player (for example, the root menu is selected as No. 1, the audio menu is selected as No. 2, the subtitle menu is selected as No. 3, and so on). By reading the PGC number from the entry search data, the reproduction address of the menu in the specified language can be automatically obtained from the description of the PGC. Note that the command for calling the menu is fixed by the type of menu regardless of the number of languages, so the same number is assigned even if the LU is different.

By the way, as shown in FIG. 1, LU is
Not only the VTSM DOM but also the VMGM DOM exists corresponding to a common language. However, in a standard application described in the DVD format, only the title menu is usually placed in the VMGM DOM. For example, as shown in FIG.
In the case of a disk having an LU in OM, VMGM DO
The state of the LU in M is as shown in FIG. That is, only one PGC (PGC # 1) exists for each of the LUs # 1 to # 4. Each LU # 1
To # 4 (PGC # 1) are VOB
Corresponding to # 17 to # 20, VOBs # 17 to # 20 are the entities of title menus in Japanese, English, French, and German, respectively.

As shown in FIG. 6, VMG is normally
Although only one type of PGC is defined in MDOM, there is no restriction that it must be one type. In the present embodiment, paying attention to this point, VMGM
The trailer PGC and VOB are arranged in the DOM.

FIG. 7 shows the PGM of the trailer in the VMGM DOM.
Structure of LU and PGC when GC and VOB are arranged and V
It shows the relationship of OB. In this example, there are three types of trailers and four languages. The fact that there are three types of trailers means that there are three types of contents, for example, there are three advertisements.
They exist in four languages. The contents of the trailer are distinguished by PGCs # 2 to # 4 for each LU, and a set of these is written in each of the four LUs # 1 to # 4. As shown in FIG. 7, in the VMGM DOM,
The data structure in which the PGC and VOB of the trailer are arranged is the basis of the data structure of the DVD according to the present embodiment.

In the example of FIG. 7, LUs # 1 to # 4
Japanese VMGM DOM and English VMGM D respectively
OM, French VMGM DOM, German VMGM DOM are supported. PGCs # 2 to # 4 of Japanese VMGM DOM (LU # 1) are VOBs # 21 to # 23, respectively.
, And VOBs # 21 to # 23 are the entities of three types of trailers in Japanese. English VMGM DOM
PGCs # 2 to # 4 of (LU # 2) are VOB
Corresponding to # 24 to # 26, VOBs # 24 to # 26 are the entities of three types of trailers in English, respectively. French VM
PGCs # 2 to # 4 of the GM DOM (LU # 3) correspond to VOBs # 27 to # 29, respectively, and VOBs # 27 to # 29, respectively.
# 29 is the entity of three French trailers. PGC # 2 of German VMGM DOM (LU # 4)
# 4 corresponds to VOBs # 30 to # 32, respectively.
OB # 30 to # 32 are the entities of three types of trailers in German respectively.

FIG. 8 shows an example of a simple reproduction control which can be realized in this embodiment. In this example, first, LU
The trailer # 1 (common) is reproduced irrespective of the setting of the LU, and subsequently, according to the LU setting, the guide trailer # 2 (J) indicating the “copy prohibition warning” in Japanese or the “Trailer # 2” in English Trailer # 2 showing "Copy prohibition warning"
It is assumed that the main program 20 of the main part is reproduced after reproducing (E). Using this example, the structure of data recorded on a DVD according to the present embodiment will be described.

In this example, since there are actually four types of contents to be reproduced, it is obvious that four types of VOBs are required. Here, VOB of trailer # 1 is VOB # 1, VOB of trailer # 2 (J) is VOB # 2, and trailer # 2 (E).
VOB of VOB # 3 and VOB of main program 20
Is VOB # 4.

Here, trailer # 1, trailer # 2
(J) and trailer # 2 (E) are VMGM DOM
, And the main program 20 belongs to TT DOM.

FIG. 9 shows the structure of the above-mentioned domain. As shown in FIG. 9A, VMGM DO
M contains the number of languages × the number of contents, that is, four PGCs
Further, as shown in FIG. 9B, the TT DOM for the main part requires one PGC, and a total of five PGCs are required. In this example, regardless of the language type, the trailer # 1 must be reproduced in common, so the PGC # 1 of LU # 1 and the PGC of LU # 2
The same VOB # 1 is applied to both # 1. next,
LU # 1 for "copy prohibition warning" displayed in Japanese
VOB # 2 is applied to PGC # 2 of LU # 2, and PGC # 2 of LU # 2 is
Is applied to VOB # 3. Also, VOB # 4 for the main program is applied to PGC # 1 of TT DOM.

FIG. 10 shows the PGC set as described above.
It shows the contents of. There are four types of PGCs as follows. As shown in FIG. 10A, the PGC of the trailer # 1 includes the PRE CMD and the VOB # 1.
And POST CMD, and as shown in (b), the PGC of the trailer # 2 (J) is PRE CMD.
, VOB # 2, and POST CMD, and (b)
As shown in FIG. 2, the PGC of trailer # 2 (E) is PR
E CMD, VOB # 3, and POST CMD, and the PGC of the main program is PRE CMD,
VOB # 4 and POST CMD. Trailer #
One PGC is used commonly by two LUs.

Next, a data structure for controlling the reproducing operation as shown in FIG. 8 will be described. As shown in FIG. 8, in order to control the reproduction operation, a navigation command (PRE CMD and PO CMD) as information for specifying the order of reproduction of the main program and the trailer is required to realize the control.
ST CMD) is required. The contents of PRE CMD and POST CMD in this example are described below.

PRE CMD of PGC of Trailer # 1
Has nothing to do. Therefore, VOB #
Play 1 Trailer # 1 PGC POST C
The MD has the content "Go to PGC # 2 of VMGM DOM." In this case, the PGM of the VMGM DOM
In # 2, the P of LU # 1 corresponding to trailer # 2 (J)
There is a GC # 2 and a PGC # 2 of the LU # 2 corresponding to the trailer # 2 (E), and one of them is selected according to the LU setting.

PREC of PGC of trailer # 2 (J)
The MD has no content to execute. Therefore, the VO
Play B # 2. PGC of Trailer # 2 (J)
The OST CMD has a content "go to PGC # 1 of TT DOM."

PREC of PGC of trailer # 2 (E)
The MD has no content to execute. Therefore, the VO
Play B # 3. Trailer # 2 (E) PGC P
The OST CMD has a content "go to PGC # 1 of TT DOM."

PRE CM of PGC of main program
The contents of D will be described later with reference to the flowchart of FIG. POST CMD of PGC of main program is
The content is that the reproduction is stopped.

Here, the PR of the PGC of the main program
Before describing the contents of ECMD, the characteristics of the DVD format used in the present embodiment will be described. The first property is for registers. The DVD player has several registers called general parameters (GENERAL PARAMETER) that are always cleared to zero when the power is turned on or when the DVD player enters a stop state. When programming navigation commands, this register can be used freely and applied to control. In the present embodiment, control programming is performed using the property that the general parameter is always cleared to zero when the stop state is attained.

The second property is that in the DVD format,
When the playback is started by pressing the play key of the DVD player in the stop state, the PG of the TT DOM must be used.
The rule is that C # 1 is referenced.

PRE CM of PGC of main program
D utilizes the above two properties. As shown in FIG. 11, PRE CMD of PGC of the main program
First, it is determined whether or not the general parameter Reg is 0 (step S101). When the general parameter Reg is 0 (Y), that is, when the power is turned on or the reproduction starts from the stop state,
Set the general parameter Reg to 1 (step S1
02), and reproduces VMGM PGC # 1 (step S
103), and the control ends. PGC of main program
When the general parameter Reg is not 0 (step S101; N), the PRE CMD sets the general parameter Reg to 0 (step S104), reproduces the main program (step S105), and ends the control.

The PGC of the main program shown in FIG.
The PRE CMD of the VMGM DOM sets the general parameter Reg to 1 when the reproduction starts after the power is turned on or from the stop state, that is, when the general parameter Reg is 0,
Play GC # 1. Thereby, P of trailer # 1
The VOB # 1, that is, the trailer # 1 is reproduced by the PRE CMD of the GC, and the POST CM of the trailer # 1 is reproduced.
By D, next, PGC # 2 of VMGM DOM is reproduced. As a result, the trailer # 2 (J) or the trailer # 2 (E) is reproduced, and then the PGC # of the TT DOM is reproduced.
1, that is, PGC of the main program is reproduced.
At this time, since the general parameter Reg is 1, the PRE CMD of the PGC of the main program shown in FIG.
Proceeding to 04, S105, reproduces its own VOB, that is, the main program. Thus, the reproduction operation shown in FIG. 8 can be controlled.

The reason why the LU is not specified by the navigation command is that it is not allowed to specify the LU by the navigation command in the DVD format. Only the destination domain and PGC number are allowed in the navigation command. The setting of the LU can be switched only by the DVD player.

Next, the structure of a DVD player for reproducing data from a DVD on which data having the above-described structure is recorded will be described. FIG. 12 shows a DVD player and its peripheral devices. This figure shows the DVD

Next, the operation of the DVD player shown in FIG. 13 will be described. First, the operation of reading information data by a DVD player will be described. In this case, the CPU 46 switches the switch 44 to the fixed contact 44b side, moves the pickup 42 and the motor 41 by servo control, and
Thus, the general control data and the entry search data are read and stored in the general control data storage area 71a and the entry search data storage area 71b, respectively. In the general control data, static information necessary for reproduction, such as the aspect ratio of video and the type and number of audio codings, is written. The entry search data includes multiplexed data for each page of the menu and multiplexed data for each title.
It is a table in which address information of the addresses written on D40 is written. Using this entry search data, the DVD player can move the pickup 42 to the specified address of an arbitrary menu or title and start reproduction.

Next, the operation of reproducing a menu by the DVD player will be described. In this case, the CPU 46
The switch 44 is switched to the fixed contact 44a side, and the start address of the menu is known from the entry search data, and the pickup 4 is read so that the information of the menu can be read.
By moving the motor 2 and the motor 41, a reproduction signal is obtained from the pickup 42. The reproduction signal is returned to a normal digital signal by the demodulator 43 and becomes a reproduction stream 60. When the reproduction stream 60 is schematically enlarged, it appears that the navigation pack (NAVI), the video signal (V), the audio signal (A), and the sub-picture signal (SP) are multiplexed and arranged in order.

Next, the reproduction stream 60 output from the demodulator 43 is converted by the demultiplexer (1) 45
The navigation pack 61 and the presentation data 62 are separated. The navigation pack 61, which is one of the separated data, is stored in the navigation control data storage area 72 of the CPU 46.

Presentation data 6 which is the other data separated by the demultiplexer (1) 45
2 are further separated into a sub-picture signal 63, a video signal 64 and an audio signal 65 by a demultiplexer (2) 47, and the decoders 48 to
By 50, the decoded sub-picture signal, video signal and audio signal are returned. The sub-picture signal output from the sub-picture decoder 48 and the video signal output from the video decoder 49 are temporarily stored in the display memories 51 and 52, respectively, and then added by the adder 53 to obtain the video output signal 67. Is output as The display memory 51 includes a CPU 4
Highlight display control signal 68 from 6
Is given. For example, when moving the highlight in response to the operation of the cursor key of the remote control device on the menu screen, the CPU 46 uses the highlight display control signal 68 to directly move the highlight to the highlight in the display memory 51. By rewriting the data at the corresponding location, the visual effect of moving the highlight color is obtained.

As described above, the PGC of each menu is grouped for each language, an LU number is given, and the VT
It is recorded on the disc as a part of an area called entry search data under the name of SM PGC information. The entry search data on the disk is taken into the CPU 46 and stored in the entry search data storage area 71b. In more detail, the general control data storage area 71a
A PGC table group indicating the correspondence between PGCs, VOB numbers, and CELL numbers is stored in the entry search data storage area 71b.
A VOB table group indicating physical addresses on the disk corresponding to C, VOB number, and CELL number is stored. Therefore, the CPU 46 determines whether the VMGM DOM or the VT
When reproducing the SM DOM, the PGC table group corresponding to the LU of the LU number held by the LU register 73 is read from the general control data storage area 71a, and as a result, the VOB number and CE of the PGC are read.
Knowing the LL number, entry search data storage area 71b
VOB number and CEL from the VOB table group
The physical address on the disk corresponding to the L number will be known.

Next, the operation at the time of PGC reproduction by the DVD player when performing the reproduction operation shown in FIG. 8 will be described with reference to the flowcharts shown in FIGS. The following operation is mainly the operation of the CPU 46 in the example shown in FIG. In this operation, when the power of the DVD player is turned on, the general parameter Reg is cleared to zero (step S111), and it is determined whether or not the play key is pressed (step S112).
If the play key has not been pressed (N), this determination is repeated. When the play key is pressed (Y), the TT DOM P
The RE CMD is executed (step S113). Here, since the general parameter Reg = 0, 1 is substituted for the general parameter Reg, and VMGM
Go to PGC # 1 of DOM (step S114). At this time, the LU number held by the LU register 73 is confirmed (step S115), and the LU corresponding to Japanese is checked.
The subsequent operation is different depending on the number or the LU number corresponding to English.

That is, if the LU number corresponds to Japanese, PGC # 1 of LU # 1 is executed, and VOB # 1, that is, trailer # 1 is reproduced (step S116).
The POST CMD of the PGC # 1 of # 1 is executed (step S117), the PGC # 2 of the LU # 1 is executed, and the VOB is executed.
# 2, that is, the trailer # 2 (J) is reproduced (step S
118), execute POST CMD of PGC # 2 of LU # 1 (step S119), and proceed to step S124.

On the other hand, in the case of the LU number corresponding to English,
The PGC # 1 of the LU # 2 is executed, the VOB # 1, that is, the trailer # 1 is reproduced (Step S120), and the POST CMD of the PGC # 1 of the LU # 2 is executed (Step S1).
21), the PGC # 2 of the LU # 2 is executed, and the VOB # 3, that is, the trailer # 2 (E) is reproduced (step S12).
3), execute POST CMD of PGC # 2 of LU # 2 (step S123), and proceed to step S124.

In step S124, P of TT DOM
RE CMD is executed (step S124). At this time, since the general parameter Reg = 1, 0 is substituted for the general parameter Reg, and VOB #
4 is reproduced (step S125). Thereby, the main program is reproduced (step S125). When the reproduction of the main program is completed, the process shifts to the stop state (step S127), and returns to step S111.

The PGC POS of the main program
If the content of the TCMD goes to the PGC number of another VMGM DOM instead of the content of "stop state", a multilingual display trailer can be placed behind the main program. PRE CMD in such a case
And examples of the contents of POST CMD are shown below.

PRE CMD of PGC of Trailer # 1
Has nothing to do. Therefore, VOB #
Play 1 Trailer # 1 PGC POST C
The MD has the content "go to PGC # 1 of TT DOM."

PREC of PGC of trailer # 2 (J)
The MD has no content to execute. Therefore, the VO
Play B # 2. PGC of Trailer # 2 (J)
The OST CMD has a content of “stop state”.

PREC of PGC of trailer # 2 (E)
The MD has no content to execute. Therefore, the VO
Play B # 3. Trailer # 2 (E) PGC P
The OST CMD has a content of “stop state”.

Main Program PGC PRE CM
D is the content shown in FIG. The POST CMD of the main program PGC is “PGM of VMGM DOM”.
Go to GC # 2. It is the content.

With the above settings, as shown in FIG. 16, after the trailer # 1 (common) is reproduced, the main program 20 which is the main part is reproduced, and finally, the trailer # 2 (J ) Or English Trailer # 2 (E).

Further, PGC # 1 and PGC # 1 of VMGM DOM
If GC # 2 is completely replaced and the above navigation command is used, first, as shown in FIG. 17, Japanese trailer # 2 (J) or English trailer # 2
In (E), for example, after the "warning" is reproduced, the main program 20, which is the main part, is reproduced.
(Common) can also be played.

As described above, according to the video data recording medium (DVD) and the video data reproducing apparatus (DVD player and its peripheral devices) according to the present embodiment, the auxiliary data reproduced along with the main video data is provided. The image data (trailer) can be reproduced for each of a plurality of languages, and the accompanying image data (the same language as the language selected by selecting the language on the menu screen) automatically suitable for the main video data Trailer) can be regenerated. Therefore, there is a great effect particularly in the case of reproducing a trailer that is meaningless unless it is displayed in each language, such as a “copy prohibition warning”.

Further, according to the present embodiment, the V of each LU
By placing a common trailer that does not depend on the language in the MGM DOM, a trailer whose contents do not want to be divided by language can be realized.

According to the present embodiment, the title number 1 can be given to the main program regardless of the reproduction order by placing the trailer in VMGMDOM instead of TT DOM (title in the trailer). Since the number 1 is not given), the quality of the disc (DVD) is improved.

The present invention is not limited to the above-described embodiment. For example, the video data recording medium according to the present invention is not limited to the DVD described in the above-described embodiment, but may be any other type of recording medium. Good. Similarly, the video data reproducing device according to the present invention is not limited to a DVD player, and may be a device that reproduces video data recorded on another type of recording medium.
