  However, in the conventional DVD playback apparatus described above, the menu screen is temporarily displayed before automatically starting playback of the content set in advance as an initial value, which gives the user a sense of incongruity. ing.

  The present invention provides a DVD playback method for reading information from a DVD on which a plurality of content information and menu information are recorded, and displaying the read content information and menu information as images. Content information is played while manually selecting one of the menus from the manual playback mode and automatically selecting a menu set as an initial value from among a plurality of menu information menus. When the menu information is read out when the automatic playback mode is selected by the operation member, the menu information is not displayed and is set as an initial value in advance in the menu information. The content information is reproduced.

  According to the present invention, the menu screen is not displayed when the content is switched in the automatic playback mode, so that the menu screen is temporarily displayed and the user can be prevented from feeling uncomfortable.

-First embodiment-
FIG. 1 is a block diagram showing a configuration of an embodiment of a DVD playback apparatus according to the first embodiment. A DVD playback apparatus 100 includes a monitor 101 that displays content video stored on a DVD, a speaker 102 that outputs sound stored on the DVD, an operation switch 103 that is operated by a user, and data from the loaded DVD. A disk drive 104 for reading data and a control device 105.

  The control device 105 includes peripheral components such as a CPU 105a and a memory 105b, and controls the transition of the top menu screen displayed when a DVD is reproduced as shown in FIG. FIG. 2A shows a conventional DVD playback device disclosed in Japanese Patent Laid-Open No. 2002-247499, which automatically executes a button command corresponding to the currently highlighted menu button on the menu for playback. The transition of the menu screen when continuing is shown. In a conventional DVD playback apparatus, when a new DVD is loaded into the disk drive 104 or when a playback instruction is given by the user, the data stored in the DVD is read. In many DVDs, the commercial video 41 is automatically displayed. Regenerated.

  Thereafter, the top menu screen 42 is displayed, and then a highlight screen 43 is displayed in which a part of the menu button blinks or becomes bright and highlighted. Here, as shown in the highlight screen 43, if the “main part playback” menu is highlighted, “main part playback” is automatically selected, and the button command corresponding to this “main part playback” is automatically executed. Is done. Note that the menu button highlighted as the initial value is generally the menu button at the top of the menu. As a result, even if the user does not perform an operation, the content main part corresponding to the menu button highlighted as the initial value is automatically reproduced, and the content main part screen 44 is displayed.

  As described above, in the screen transition in the conventional DVD playback apparatus described above, the top menu screen 42 and the highlight screen 43 are temporarily displayed after the commercial video 41 is displayed until the main content screen 44 is displayed. Is displayed. As the screen is switched in such a short time, it appears to the user that screen flickering has occurred, resulting in a screen transition in which the user feels uncomfortable. In addition, there is a possibility that the user will be mistaken for a failure.

  On the other hand, the DVD playback apparatus 100 according to the embodiment has an automatic playback mode and a manual playback mode as playback modes as described below. Note that the playback mode is set in advance by the user using the operation switch 103.

(1) Automatic playback mode When the automatic playback mode is set, the screen transitions as shown in FIG. That is, when a new DVD is loaded into the disk drive 104 or a reproduction instruction is given by the user, information recorded on the disk is read and a commercial video 41 is displayed. Thereafter, the menu button highlighted as the initial value among the menu buttons corresponding to the menu screen is automatically selected and executed.

  Until the execution of the button command corresponding to the selected menu button is completed, the top menu screen 42 and the highlight screen 43 are displayed on the monitor 101 even if the menu information is read from the DVD by the disk drive 104. Instead, the skip screen 45 is displayed. The skip screen 45 is a screen for presenting to the user that the display of the menu screen is omitted. For example, a message such as “skip menu is displayed” is displayed. While the skip screen 45 is displayed on the monitor 101, the sound output from the speaker 102 is turned off. Thereafter, when the main content corresponding to the menu button highlighted as the initial value is automatically reproduced, the main content screen 44 is displayed and the volume of the sound is restored.

(2) Manual regeneration mode When the manual regeneration mode is set, the top menu screen 42 and the highlight screen 43 are displayed on the monitor 101. While the highlight screen 43 is displayed, it waits until any menu button is selected by the user. When one of the menu buttons is selected by the user, the content main part corresponding to the selected menu button is reproduced, and the content main part screen 44 is displayed.

  In this way, when the automatic playback mode is set, instead of displaying the conventional top menu screen 42 and highlight screen 43, the skip screen 45 is displayed instead and the menu screen is displayed to the user. Since a message to the effect of omitting is displayed, it is possible to make a natural screen transition without giving the user a sense of incongruity when content reproduction is automatically continued. Furthermore, it is possible to give a sense of security by notifying the user of omission of the menu display. Since the audio output from the speaker 102 is turned off while the skip screen 45 is displayed on the monitor 101, the DVD on which music and audio are reproduced while the top menu screen 42 and the highlight screen 43 are displayed. However, it is possible to prevent unnatural music and voice switching caused by skipping the menu screen.

  FIG. 3 is a flowchart showing the operation of the DVD playback apparatus according to the first embodiment. When a new DVD is loaded into the disk drive 104 or when the user gives an instruction to reproduce the DVD, the control device 105 starts the process shown in FIG. First, DVD playback preparation processing is executed in steps S10 to S30.

  In step S10, the reproduction mode set by the user is read by the operation switch 103. In step S20, the volume management information recorded in the volume management information area (not shown) of the DVD is read and stored in the memory 105b. In the subsequent step S30, the story information included in the read volume management information is acquired. In step S40, data is read from a DVD video area (not shown) of the DVD, and playback of the DVD is started based on the story information. In step S50 after the start of reproduction, it is determined whether or not the top menu screen 42 is reproduced based on the volume management information stored in the memory 105b.

  If it is determined that the top menu screen 42 is reproduced, the process proceeds to step S60, and highlight information on the menu button selected on the highlight screen 43, that is, the menu button highlighted as the initial value is displayed in the DVD video area of the DVD. Get from. In step S70, it is determined whether or not the automatic reproduction mode is selected. If the reproduction mode is the automatic reproduction mode, the process proceeds to step S80.

  In step S80, the skip screen 45 is displayed instead of the top menu screen 42 and the highlight screen 43 on the monitor 101, and the sound output from the speaker 102 is turned off. As a result, while the top menu screen 42 and the highlight screen 43 are being skipped, the top menu screen 42 and the highlight screen 43 are being skipped for the user while preventing a screen transition that would give the user a sense of incongruity. To give you a sense of security and erase unwanted voices. In step S90, a button command corresponding to the highlighted menu button is acquired from the highlight information and is automatically issued.

  In step S100, the button command is executed to start playback of the main content corresponding to the menu button. At the same time, the skip screen 45 is erased from the monitor 101 in step S110, and the sound is restored to the original volume. As a result, the main content screen 44 is displayed on the monitor 101, and the main content audio is output from the speaker 102.

  On the other hand, when the regeneration mode is the manual regeneration mode, the process proceeds to step S130. In the manual reproduction mode, the top menu screen 42 and the highlight screen 43 are not skipped and are displayed on the monitor 101. The user needs to select the menu button he / she wants to execute by looking at the highlight screen 43 displayed on the monitor 101. When the menu button is selected by the user in step S130, the process proceeds to step S140.

  In step S140, a button command is acquired and issued from highlight information corresponding to the menu button selected by the user. In the subsequent step S150, the button command is executed to reproduce the main content corresponding to the menu button. As a result, the main content screen 44 is displayed on the monitor 101, and the main content audio is output from the speaker 102.

  In step S120, it is determined whether the data currently read by the disk drive 104 is data stored in the lead-out area of the DVD. If the currently read data is not the data stored in the lead-out area, it means that the DVD is still being reproduced, and the process returns to step S50 and the above-described processing is repeated. On the other hand, if the currently read data is data stored in the lead-out area, it is determined that the reproduction has been completed up to the end of the data stored in the DVD, and the process ends.

As described above, according to the first embodiment, the following operational effects can be obtained.
(1) In the automatic playback mode, even if the data of the top menu screen 42 and the highlight screen 43 is read from the DVD, the data is skipped without being displayed, and during the skip, the skip screen 45 is displayed and the sound is turned off. . Accordingly, it is possible to prevent the unnecessary top menu screen 42 and highlight screen 43 from being displayed and flickering even though automatic reproduction is in progress, and to make a natural screen transition without a sense of incongruity. Furthermore, it is possible to prevent unnatural music and voice switching while skipping the menu screen 42 and the highlight screen 43.
(2) On the menu screen 42 and the skip screen 45 displayed while skipping the highlight screen 43, a message for guiding the user that the menu is currently skipped is displayed. As a result, the user can grasp that the menu is being skipped, and get a sense of security.

The predetermined value of the vehicle speed is set to a reference value for determining whether or not the host vehicle is traveling, for example, 5 km / h. Further, a message such as “DVD image is not displayed during travel” is displayed on the travel restriction screen.

  FIG. 5 is a flowchart showing the operation of the DVD playback apparatus 100 according to the second embodiment. When a new DVD is loaded into the disk drive 104 or when the user gives a DVD playback instruction, the control device 105 starts the process shown in FIG.

  In step S210 to step S260, processing similar to that in step S10 to step S60 of FIG. 3 in the first embodiment is executed. In step S270, it is determined whether or not the host vehicle is traveling based on the vehicle speed detection value by the vehicle speed sensor 201. If it is determined that the host vehicle is not running, the process proceeds to step S280.

  In step S280, if the above-described travel restriction screen is currently displayed on the monitor 101, the travel restriction screen is deleted, and a DVD playback image is displayed on the monitor 101. Thereafter, in steps S290 to S360, processing similar to that in steps S70 to S150 in FIG. 3 in the first embodiment is executed.

  On the other hand, if it is determined that the host vehicle is traveling, the process proceeds to step S370. In step S370, a travel restriction screen is displayed on the monitor 101. This prevents the driver from being distracted by the DVD image and being unable to concentrate on driving.

  In step S380, it is determined whether or not the reproduction mode is the automatic reproduction mode. If the automatic reproduction mode is selected, the process proceeds to step S390. Here, in the first embodiment, the skip screen 45 is displayed on the monitor 101 and the sound output from the speaker 102 is turned off. However, in the second embodiment, since the travel restriction screen is already displayed on the monitor 101, only the sound output from the speaker 102 is deleted in step S390.

  In steps S400 to S410, processing similar to that in steps S90 to S100 of FIG. 3 in the first embodiment is executed, and in step S420, the sound is restored. As a result, similarly to the first embodiment, the top menu screen 42 and the highlight screen 43 are automatically skipped, and the content corresponding to the menu button highlighted on the menu screen is automatically reproduced. However, in this case, since the vehicle is traveling at a predetermined vehicle speed or higher and the travel restriction screen is displayed on the monitor 101, the DVD video is not provided to the user, and the playback sound of the DVD is output from the speaker 102. Will be output.

  On the other hand, when the automatic regeneration mode is not selected, that is, when the manual regeneration mode is selected, the process proceeds to step S430. In the first embodiment described above, when the playback mode is not the automatic playback mode, the top menu screen 42 and the highlight screen 43 are displayed on the monitor 101, and the user selects a button on the highlight screen 43.

Is not displayed on the monitor 101.

  In this case, since the user cannot select the menu button on the highlight screen 43, the reproduction is continued according to the reproduction information stored in the DVD. For example, if the playback information is defined so as to stop on the highlight screen 43 until the menu button on the highlight screen 43 is selected by the user, the playback screen stops on the highlight screen 43. Further, when the reproduction information is defined to reproduce the CM video when there is no operation by the user for a certain period of time after the highlight screen 43 is displayed, only the audio of the CM is reproduced.

  In step S440, it is determined whether the data currently read by the disk drive 104 is data stored in the lead-out area of the DVD. If it is determined that the currently read data is not the data stored in the lead-out area, since the DVD is still being reproduced, the process returns to step S250 and the above-described processing is repeated. On the other hand, if it is determined that the currently read data is the data stored in the lead-out area, it is determined that the reproduction has been completed up to the end of the data stored in the DVD, and the process is terminated.

  As described above, according to the second embodiment, the following effects can be obtained in addition to the operational effects of the first embodiment. When the host vehicle is traveling, the travel restriction screen is displayed without displaying the DVD image on the monitor 101. Further, when the automatic playback mode is set at this time, the top menu screen 42 and the highlight screen 43 are displayed. The sound was turned off during skipping. Thereby, even when the travel restriction screen is being displayed, it is possible to prevent unnatural music and voice switching while skipping the menu screen.

However, a voice guidance “currently skipping the menu screen” may be broadcast via the speaker 102 while the skip screen 45 is displayed.

  In the first and second embodiments described above, while the top menu screen 42 and the highlight screen 43 are skipped, the skip screen 45 is displayed on the monitor 101 and “menu is skipped”. As a result, the user is now informed that the menu screen is being skipped. However, instead of this, the user may be informed that the menu is being automatically selected, such as “The menu is automatically selected”. In addition, a message that gives the user a sense of security, for example, “please wait for a while” may be displayed to guide the user.

  In the first and second embodiments described above, the transition of the top menu screen displayed when a DVD is played back has been described. However, a story to be played back from a plurality of stories is displayed on a branch screen. The same effect can be obtained even if the present invention is applied to a so-called multi-story branch screen in which various stories can be selected by selection.

  In the first and second embodiments described above, the sound output from the speaker 102 is turned off while the top menu screen 42 and the highlight screen 43 are skipped. However, the sound may be reduced. Good.

  In the second embodiment described above, an example in which only the reproduction sound of the DVD is output from the speaker 102 when the own vehicle is running and the running restriction screen is displayed on the monitor 101 is shown. While driving, neither video nor audio may be output.
