It is explanatory drawing which shows.

As shown in FIG. 1, the data in the disc is roughly divided into two types of data group forces. One is the Video 'Manager (VMG) 1 and the other is the Video' Title 'Set (VTS) 11A-1 ID. VMG1 consists of a video 'manager information (VMGI) 2, a VMG menu video' object 'set (VMGM-VOBS) 9 and a VMGI backup 10. The VMGM-VOBS9 in this example is composed of NTSC video as shown by menu 40B in FIG. Menu 40B contains a number of buttons corresponding to each of a plurality of titles recorded in the NTSC format (in this example, “USA: United States travel guide video” and “Japan: Japan travel guide video”). In this example, there are 2 buttons) 42A and 42B. The user can select and decide buttons 42A and 42B with the input device of the player. The operation when the button is determined (when the title to be played back is specified) is described in post command 6 in BTN-CMD39 and VMGM-PGCI3 in FIG. 2 described later.

[0016] In VMGI2, there is a VMGM program · chain · information (VMGM-PGCI) 3, which includes a program · chain · command · table (PGC-CMDT) 4. In PGC CMDT4, navigation command pre-command 5 and post-command 6 And a total of 128 cell commands 7 can be described. In this embodiment, the navigation commands shown in FIG. 4 and FIG. In addition, the navigation command shown in FIG. 6 is described in the post command executed after the button is selected and determined and the button command BTN-CMD39 is executed. Note that in the DVD-Video disc format, there are as many VMGM-PGCI3s as the number of program chains (PGC) that make up the menu.

[0017] In VMGI2, a first 'play PGCI (FP-PGCI) 8 can be described in order to specify an operation when a disc is inserted into the player. In this embodiment, a navigation command for jumping to the VMG menu first is described as a pre-command.

[0018] On the DVD—Video disc format, VTS11 can have 1 to 99.

In this embodiment, there are four VTS 11A to: L 1D, and each VTS 11 (11A to 11D) is video · title · set information (VTSI) 12 and VTS menu video · object · set HVTSM— VOBS) 23, VTS title video object 'set (VTSTT—VOBS) 24 and VTSI backup 25.

[0019] Furthermore, VTS program 'chain' information (VTS—PGCI) 13 exists in VTSI12 by the number of PGCs that make up the title, and VTSM 12 contains VTSM program 'chain' information (VTSM—PGCI). 18) There are as many PGCs that make up the VTS menu. The VTS-PGCI 13 includes a program “chain” command “table (PGC-CMDT) 14. PGC—In CMDT14, a total of 128 navigation commands including pre-command 15, post-command 16 and cell command 17 can be described.

[0021] On the DVD—Video disc format, VTS 11 can have multiple titles, and discs with various configurations are possible as the format allows. In this embodiment, as shown in Table 1, it is composed of two PAL VTSs (11A, 11 B) each having one title and two NTSC VTSs (11C, 1 ID). [0022] [Table 1]

Table 1 Video content

[0023] The title is recorded in the VTSTT-VOBS24 of each VTS11 (11A to 11D), and the VTSM-VOBS23 which is the VOBS for the menu exists in one of the VALs for the PAL system. In this embodiment, it is composed of PAL video such as menu 40A in FIG. In addition, although not shown in FIG. 1, other VTS 11B except VTS11A: The menu screen does not exist in L 1D! Therefore, VTSM-VOBS23 does not exist!

The navigation command of FIG. 4 is described as the pre-command 20 in the PGC-CMDT 19 of the VTSM-PGCI 18 in the VTSM-VOBS 23. Further, the navigation command shown in FIG. 8 is described in the post command 21 that is executed after the button is selected and determined and the button command BTN-CMD39 is executed. As shown in FIG. 3, the menu 40A has two buttons 41A and 41B, and the user can select and decide the buttons with the input device of the player. The operation when the button is determined is described in BTN-CMD39 described later.

[0025] It should be noted that the content of the PGC-CMDT14 in the VTS-PGCI 13 may be anything, and it does not matter if the PGC-CMDT14 does not exist. In this embodiment, the configuration is as described above. However, any configuration can be used as long as the DVD-Video disc format permits. For example, a PAL menu may be a single VTS, and it may be composed of a total of 5 VTSs, 4 VTSs for titles and 1 VTS for menus.

[0026] Here, referring to FIG. 2, VMGM VOBS9, VTSM VOBS23, VTSTT VO The structure of a video 'object' set (VOBS) 26 such as BS24 will be described. VO BS26 consists of one or more video objects (VOB) 27, and VOB27 consists of one or more cells (CELL) 28. Cell 28 consists of one or more VOB units (VOBU) 29, and VOBU 29 consists of one navigation 'pack (NV-PCK) 30 and zero or more audio' packs (A_PCK) 31 and zero or more. The video 'pack (V_PCK) 32 and zero or more sub-picture' pack (SP-PCK) 33 power.

The NV-PCK 30 includes playback control information (PCI) 34 and data search information (DSI) 35. The PCI 34 has a highlight information (HLI) 36, and the HLI 36 has a button information table (BTNIT) 37. If a valid button exists in VOBU29, valid data also exists in BTNIT37, and a button command (BTN-CMD) 39 that is a navigation command is described in button information (BTNI) 38 of the corresponding button. . In this embodiment, the navigation command of FIG. 7 is described in BTN-CMD39 of VMGM-VOBS9 and VTSM-VOBS23.

[0028] The DVD—Video disc contains other information such as the file system. VMGI2, VMGM—VOBS9, VMGI backup 10, VTSI12, VTSM—VOB S23, VTSTT—VOBS24, VTSI backup 25 Etc. can be accessed as files.

[0029] The operation of the above configuration will be described. When the DVD—Video disc is inserted into the player or the power is turned on with the disc inserted, the PGC—CMDT pre-command in the FP-PGCI8 existing in the disc is executed and the VMG menu is jumped to.

[0030] In the VMG menu, pre-command 5 is first executed to decide whether to play the NTSC menu (VMG menu) or the PAL menu (VTS menu), and play the determined menu. When the menu is played, the NTSC menu and PAL menu! As shown in Fig. 3 will be displayed as one of the video screens, and a button for selecting the title will be displayed.

[0031] Here, the navigation command that is the reproduction command information of the first embodiment shown in Figs. 4 to 8 will be described in detail. The navigation command in Figure 4 is the menu selection 'play command It is. This menu selection 'playback command is described in VMGM2 VMGM—PGCI3 PGC—CMDT4 precommand 5 and VTSM—VOBS23 VTSM—PGCI18 PGC—CMDT19 precommand 20.

[0032] In the menu selection 'replay command, first, it is determined whether or not the system parameter power of the player is the regional code power “l” of the player (S101). If it is “1” (S101 : Yes), since the playback device has North American specifications, it is determined that the TV system of the TV monitor connected to the playback device is the NTSC system, the process proceeds to step S108, the NTSC menu is played, and the process is terminated. On the other hand, if it is not “1” (S101: No), the process proceeds to step S102.

[0033] In step S102, it is determined whether or not the regional code power of the regenerator is “2”. If it is “2” (S102: Yes), the regenerator specification is either Japanese or European. Therefore, proceed to Steps S103 to S106, and Japan is set to one of “Sound initial language code”, “Subtitle initial language code”, “Menu description language code”, or “Parental management country code”. If Japan is set in any of them (S 103: Yes, S104: Yes, S10 5: Yes or S106: Yes), it can be assumed that the player is Japanese specification. It is determined that the TV system of the TV monitor connected to the player is the NTSC system, and the process proceeds to step S108, where the NTSC menu is played and the process is terminated.

[0034] On the other hand, when the area code of the playback device is “2” (S101: Yes), “Sound initial language code”, “Subtitle initial language code”, “Menu description language code”, “Parent management” If Japan is not set in any of the “National Codes” (S103 to S106 are all No), the TV system power AL of the TV monitor connected to the player can be estimated because the player can be assumed to be European. It is determined that this is the method, and the process proceeds to step S107, where the PAL menu is reproduced and the process is terminated.

In this embodiment, if the area code of the playback device is neither “1” nor “2” (S101: No), it is determined that the TV system of the TV monitor connected to the playback apparatus is the PAL system, and the process proceeds to step S107. The ability to play the PAL menu and finish processing If necessary, play the PAL system or the NTSC in the other area codes as in the case where the area code is “1” or “2”. A determination may be made as to whether or not to reproduce the method.

The navigation command in FIG. 5 is a force menu playback request that is a title jump request. This is a determination command for determining whether or not there is. This determination command is described in VMGM2 VMGM—PGCI3 PGC—CMDT4 precommand 5. As described above, the pre-command 5 also includes a menu selection / replay command, and in the pre-command 5 in which the two commands exist, the determination command is executed first.

[0036] The determination command uses a predetermined storage area: GPRM [0], and if the value of GPRM [0] is "0", it is determined that the request is a menu playback request by a user operation or the like during title playback. If the value of GPRM [0] is “l”, it is determined that the request is a title jump request (S111). In the case of a menu playback request (SI 11: No), the next pre-command “menu selection” playback command is executed for menu playback (S113). In the case of a title jump request (Sil l: Yes), execution of the next pre-command is stopped and execution of the post-command is started to jump to the title (S112).

The navigation command in FIG. 6 is a title reproduction command for reproducing a title selected with a button on the menu. This title playback command is described in VMGM—PGCI 3 PGC—CMDT4 Post Command 6! In the title playback command, “0” is substituted for GPRM [0] to start menu playback (when a menu playback request is made) by user operation during title playback (S121), and storage area: GPRM [1] Jumps to the title number set in (S122). In GPRM [1], the title number is set by the title number setting command in Fig. 7.

[0038] The title number setting command in Fig. 7 is a navigation command set in BTN-CMD39. When a button is selected on the menu, the title number setting command of BTN-CMD39 for the corresponding button is executed, and the title number assigned to this button (corresponding BTN-CMD39) in S131 is GPRM. Substituting into [1], in the case of VMG menu, jumps to VMGM—post command 6 (title playback command) in PGCI3, and in the case of VTS menu, VTSM—post command 21 in PGCI18 (title jump specification command) ) Will jump to the VMG menu, where the title jump is determined by the pre-command 5 judgment command in VMGM—PGCI3, so post command 6 (title playback command) in VMGM—PGCI3 is executed in S112. .

[0039] The title jump designation command in FIG. 8 is a postscript described in VTSM PGCI18. This command is executed after the VTS menu button command (title number setting command) is executed. In the title jump specification command, select menu 'play command'

In order to determine that it is a title jump request in (VMGM—PGCI3 pre-command), “1” is substituted into GP RM [0] (S141), and jumps to the VMG menu (S142).

[0040] Next, during menu playback, determine the TV system of the TV monitor connected to the playback unit from the system parameters of the playback unit, and connect to the playback unit from the NTSC menu and PAL menu in Fig. 3 The method of selecting and playing a menu that matches the TV format of the TV monitor is described in detail in the order of (Example 1), (Example 2), and (Example 3).

[0041] (Example 1): When a user plays a disc according to this embodiment on a DVD—Video player released in the United States.

When the region code of the player sold in the United States is determined, the region code of the player is 1 (S101: Yes), so the NTSC menu (VMG menu in this embodiment) is played (S108). . As a result, the menu screen 40B in FIG. 3 is reproduced.

[0042] On the menu screen 40B, if the user wants to see a Japanese travel guide, the user selects and determines the appropriate button 42B using the input device of the player. Since Japan's travel guide video corresponds to title 4 in Table 1, BTN—C MD39 corresponding to button 42B assigns 4 to GPRM [1] as the title number according to the command shown in FIG. 7, and the post in V MGM—PGCI Move on to execution of command 6 (S131).

[0043] Post command 6 is set to GPRM [1] by substituting 0 for GPRM [0] to start menu playback due to user operation, etc. during title playback according to the flowchart in Fig. 6 (S121). Jump to the current title number (S122). In this embodiment, the VTS has only one title, and the VTS number and title number match, so the title jumps to the title of the VTS with the value of GPRM [1].

On the other hand, when playback of the VMG menu is started by a user operation during title playback, the pre-command 5 in VM GM—PGCI3 is executed. At this time, since the value of GPRM [0] is 0 in S121, it is determined as a menu request in FIG. 5 (Sll, S113), and pre-command 5 in FIG. 4 is executed. As described above, the result is the NTSC menu (VMG in this example). Menu) is played back.

[0045] (Example 2): When a user plays a disc according to this embodiment on a DVD—Video player released in the UK.

In FIG. 4, when the region code of the player sold in the United Kingdom is determined, the region code of the player is 2 (S101: No, S102: Yes), so the process proceeds to step S103.

[0046] There is almost no case where Japanese is set in the "Initial audio code", "Initial subtitle language code" and "Menu description language code" of the player used in European countries including the UK. Since there is almost no case where Japan is set in the “Parental Management Country Code”, all judgments in S103 to S106 are No and Step S107 is executed. As shown in Table 1, since the PAL menu is the first VTS menu, the jump command jumps to the first VTS menu and executes the precommand 20 in VTSM-PGCI18. Pre-command 20 consists of the navigation commands shown in Fig. 4. Therefore, the TV system is judged again, but S 107 comes again, so the VTS menu is played as it is !, menu 40A in Fig. 3 Will be played.

[0047] On the menu screen 40A, if the user wants to see a French travel guide, the user selects and determines button 41B using the input device of the player. Since the French travel guide video corresponds to title 2 in Table 1, it corresponds to button 41B. In BTN—CMD 39, 2 is substituted for GPRM [1] as the title number in accordance with FIG. 7, and the process proceeds to execution of post command 21 in VTSM—PGCI (S131).

[0048] In the DVD—Video disc format, it is not possible to jump to another VTS title from the VTS menu. Therefore, the post command 21 in VTSM—PGCI starts with VMGM—PGCI3 as shown in FIG. Substitute 1 in GPRM [0] to make it a title jump request with the pre-command of (S141), and jump to the VMG menu to execute a title jump with post command 6 of the VMG menu (S 142) ). In VMG menu, VMGM—pre-command 5 in PGCI3 is executed. In the pre-command 5, first, it is determined whether or not it has jumped for the title jump according to FIG. 5 (S111). Since 1 is assigned to GPRM [0] in the post command 21 of the VTS menu, it is determined as a title jump, execution of the precommand 5 is stopped, and execution of the post command 6 is started (S112). [0049] Post command 6 jumps to the title number set in GPRM [1] according to the flowchart of FIG. 6 (S121, S122). In this example, the VTS has only one title, and the VTS number and title number match, so it is necessary to jump to the VTS title with the value of GPRM [1].

[0050] On the other hand, when playback of the VMG menu is started by a user operation during title playback, a pre-command in VM GM—PGCI3 is executed. At this time, the value of GPRM [0] is 0, so in FIG. 5 it is determined that the request is a menu (Slll: No), and the pre-command in FIG. 4 is executed. As a result, the PAL menu (in this example, the VTS menu) is reproduced as described above.

[0051] (Example 3): Released in Japan! DVD-Video player playing the disc in this example.

In Fig. 4, when the region code of the player sold in Japan is determined, the region code is 2. Therefore, if the TV system is determined only by the region code, the PAL menu (in this example, the VTS menu) However, one or more of the “audio initial language code”, “subtitle initial language code”, and “menu description language code” of most players is set to Japanese, Since Japan is set in the “Rental Management Country Code”, at least one of the determinations in Steps S103 to S106 in FIG. 4 is Yes, and the process proceeds to Step S108 and the NTSC menu ( In this embodiment, the VMG menu) is played back. As a result, the menu screen 40B in FIG. 3 is reproduced. Subsequent operations are the same as those in the example of the United States regenerator described above.

[0052] Next, the optical disc recorder 100 of Example 1 will be described. The optical disc recorder 1100 includes a plurality of menus created in a television system corresponding to each television system of video, and playback command information for playing back a menu that matches the television system of the television monitor connected to the playback device. It is recorded on a DVD disc.

FIG. 9 is a block diagram illustrating a configuration of the optical disc recorder 100 according to the first embodiment.

The optical disc recorder 100 includes an encoding unit 110 that encodes an input video signal and audio signal, a navigation information creation unit 120 that creates navigation information that is playback control information when the disc is played, From navigation information creation part 120 Navigation information and the video and audio data output from the encoding unit 110 and a disk read Z write unit 140 that writes and reads the multiplexed data to and from the disk. And a menu creation unit 130 for creating a disc menu, a CPU 150 for controlling the menu, and a memory 160 for storing information. The menu creation unit 130 corresponds to the menu creation unit of the present invention, the navigation information creation unit 120 corresponds to the navigation information creation unit of the present invention, and the disc Z write unit 140 corresponds to the recording unit of the present invention. It corresponds to.

[0054] Also, the encoding unit 110 includes a TV system determination circuit 111 that determines the TV system of the input video, an AZD converter 112 that converts a video analog signal into a digital signal, and MPEG digital video data. It comprises an encoding circuit 113 for converting into a format, an AZD converter 114 for converting an audio analog signal into a digital signal, and an encoding circuit 115 for converting audio digital data into a format such as MPE G. The encoding circuit 113 supports two types of TV systems, NTSC and ZPAL.

[0055] The menu creation unit 130 includes a thumbnail image creation unit 131 that creates a thumbnail image of each title, menu image data 132 that serves as a menu background, character information 133 that is added to the menu, Button information 134, which is information on the color, shape, position, etc., for the buttons for selecting titles, etc., and a video composition unit 135 that synthesizes image data, etc. 136, and a multiplex state unit 137 that multiplexes the converted data and the navigation information created by the navigation information creation unit 120.

The operation of the above configuration will be described.

When video (title) recording is started under the control of the CPU 150 by the optical disc recorder 100, the video input is converted into digital data by the AZD converter 112 after the TV system is determined by the TV system determination circuit 111. Next, the digital data is converted into MPEG data by the encoding circuit 113.

On the other hand, the audio input is converted into digital data by the AZD converter 114 and converted into data such as MPEG by the encoding circuit 115. Next, the encoded audio data together with the video data is a navigation information creation unit 1 according to the instruction from the CPU 150. 20 is sent to the multiplex part 116 together with the navigation information created by the multiplex unit 116, multiplexed by the multiplex part 116, and recorded on the disk by the disk read / write unit 140.

When recording a title, the CPU 150 obtains the TV system discriminated by the TV system discriminating circuit 111 and stores it in the memory 160 together with recording information such as video title information. Thereafter, at the end of recording the title, the CPU 150 creates an information file including the navigation commands shown in FIGS. 4 to 7 in the navigation information creation unit 120 and records it on the disc in the disc read / write unit 140. .

[0059] When the recording of the title is finished and finalization operation is instructed, the menu creation unit 130 creates a plurality of TV system menus (VMG menu and VTS menu) corresponding to each TV system, Disc read The data is recorded on the disc by the Z write unit 140. In order to create a thumbnail image for each title, a part of the video for each title is read from the disk read Z write unit 140 and converted to a thumbnail image for the menu by the thumbnail image creation unit 131. To do. Next, the thumbnail image, the menu image data 132 serving as the menu background, the character information 133, and the button information 134 are combined by the image combining unit 135 to create a menu image. At this time, the CPU 150 creates a menu in the TV system corresponding to each TV system in accordance with the TV system of each title stored in the memory 160.

[0060] The menu video (menu screen) synthesized by the video synthesis unit 135 is converted into an MPEG video by the encoding unit 136, and the menu button created by the navigation information creation unit 120 is pressed. Along with navigation information such as a navigation command describing the operation, it is multiplexed by the multi-placet section 137. The multiplexed data is recorded on the disk by the disk read / write unit 140. The CPU 150 creates an information file for the entire disc including the menu at the navigation information creation unit 120 and records it on the disc at the disc read Z write unit 140. Finally, the CPU 150 instructs the disc read Z write unit 140 to finalize the disc and completes the disc.

[0061] According to the optical disc recorder 100 of the first embodiment, for each TV system of titles (videos), a menu is created in the corresponding TV system, and further, the system parameters of the playback device that plays the disc at the time of menu playback Determine the TV system of the TV monitor connected to the player. Thus, it is possible to create the DVD-Video disc of this embodiment in which the playback command information for playing back the menu that matches the TV system of the TV monitor connected to the playback device is recorded. In other words, it is possible to create the same TV system menu as the recorded video, and to create a disc with navigation information added to determine the TV system menu to be played back based on the region code of the playback device.

[0062] When the disc of Example 1 is played back, the TV system menu that matches the TV system of the player is automatically selected and played back, so there is no image disturbance due to the difference in the TV system. The menu screen is not disturbed and the user does not feel uncomfortable or the operation is difficult.

[0063] In the first embodiment, the "region code", "audio initial language code", "subtitle initial language code", "menu description language code", and "normtal management" set in the system parameters of the player An example of determining the TV system by referring to “Country Code” has been shown, but if the region where the disc to be played can be limited, the navigation command in FIG. 4 should be determined using only the region code (S101). May be. In other words, if the disc is only for North America and Europe, the NTSC menu may be played with a region code of 1, and the PAL menu may be played for others. However, the system parameter is a parameter that must be possessed by a DVD-Video player, and is set in a player in any region. Therefore, the method described in the first embodiment is more desirable. ,.

[0064] Also, in the first embodiment, in addition to the power menu for creating menus corresponding to the two TV systems, it can be realized as menu-like titles. That is, the menu is generally realized by a menu (VMGM—VOBS, VTSM—VOBS), but may be a title (VTSTT—VOBS), a still image, or a moving image. When you prepare a still image and a button with the title (V TSTT-VOBS) and jump after selecting the button, the power format that is a menu from the user's point of view may be a title.

[0065] Furthermore, in Example 1, the power realized by the VMG menu for the NTSC menu may be realized by another VTS menu.

That is, the PAL menu and title 1 in the first VTS Title 2 in the second VTS

The third VTS has NTSC menu and title 3

Title 4 in the fourth VTS

It is recorded as such.

[0066] Also, in the first embodiment, only one menu is output by the TV system on the playback device side (normally, only one TV system is supported). Therefore, in many cases, the same effect can be obtained by executing the navigation command shown in FIG. 4 only when a disc is inserted. In other words, the navigation command shown in Fig. 4 can be described only in FP-PGCI.

Example 2

[0067] The information recording medium of the second embodiment is an example applied when a video (title) is recorded on one disc in either the NTSC system or the PAL system in one TV system. In addition, the information recording medium of Example 2 is an information recording medium capable of recording video by using two types of TV systems, NTSC system and PAL system, and one of the NTSC system or PAL system is the TV system. The created menu is recorded, the warning screen created by the other TV system is recorded, and the system parameter of the player to be played is also connected to the player when playing the menu. The TV system of the TV monitor is determined, and the menu or warning screen that matches the TV system of the TV monitor connected to the player is played out of the menu or warning screen.

[0068] In Example 1 described above, titles are recorded in two TV systems, NTSC and PAL, and menus are created in NTSC and PAL corresponding to these titles. Even when video (title) is recorded on only one TV system on a single disc, there is a similar problem that operation is difficult due to image disturbance due to the difference in TV system.

[0069] In Example 2, a menu is created only in the TV system in which the video (title) is recorded, and the video is recorded. ヽ For the TV system, a warning screen (still image in the corresponding TV system). Or video). For example, if the video recorded on the disc is only PAL video, create menu 40A using PAL and NTSC video as shown in Fig. 10. Create warning screen 42. In the case of Fig. 10, if the TV format of the TV monitor connected to the player is SPAL, menu 40A is displayed. If the TV format of the TV monitor is NTSC, the warning screen 42 is displayed. Is displayed.

[0070] In this case, the system parameter of the playback device to be played back and the TV system connected to the playback device are determined, and the menu or warning screen of the TV monitor connected to the playback device is determined. A navigation command that reproduces a menu or warning screen that matches the TV system can be realized by replacing S108 in the navigation command in Fig. 4 with "Play NTSC warning screen" instead of "Play NTSC menu". In other words, basic TV system determination and warning screen reproduction can be performed in the same manner as in the first embodiment.

A reference numeral 43 in the warning screen 42 in FIG. 10 indicates a time counter. In this example, when the video corresponding to the TV system of the TV monitor connected to the playback device is not recorded on the disc, the warning screen 42 is played back, and the time counter 43 starts counting down at the same time. Stops automatically (disk EJECT etc.) after elapse of time (for example, after 30 seconds).

FIG. 11 shows an example of another warning screen 44. In the case of Fig. 11, the T connected to the player

Menu 40A is displayed when the TV system power PAL system of the V monitor is used, and a warning screen 44 is displayed when the TV system of the TV monitor is the NTSC system. In the warning screen 44, the STOP button 45,

PLAY button 46 is arranged. This warning screen 44 has the advantage that playback can be started even if the TV system is different. If you actually want to confirm that a TV screen is compatible with both TV systems, even if the warning screen 44 “TV system cannot be played because it is different” is played, for example, if your TV monitor supports both TV systems, In some cases, undistorted images are played back, which is useful in such cases. By selecting the operation (operation) after warning in this way, further convenience can be provided. The configuration of the warning screen is not limited to the configuration examples of the warning screen 42 in FIG. 10 and the warning screen 44 in FIG. For example, "

The number of videos recorded on the disc, the amount of data, etc. may be displayed along with a warning that the TV system is different and cannot be played.

[0073] Note that the warning screen is also displayed in the menu (VMGM VOBS, VTSM VOBS) TSTT—VOBS), still images or videos! /.
