Description

  The present invention relates to a display device suitable for a vehicle, and more particularly to a display device capable of selectively displaying video information from a disc playback device such as a DVD player in addition to map information from a navigation device.

  Conventionally, as a vehicle-mounted display device, a multifunction device of a navigation device and a disc playback device (DVD player) is mounted, and map information from the navigation device and video information from the DVD player can be selected and displayed on the display, respectively. There is. In such a display device, when the user wants to display map information, he selects map information from the navigation device, and when he wants to display video information from the DVD player, he selects video information from the DVD player and displays it on the display. I am trying to output.

  On the other hand, it is also possible to display map information from the navigation device on the display and output audio information from the DVD player from the speaker. This is a case where the user is driving and cannot watch the video, and only the audio information of the DVD is output to the speaker without displaying the video information from the DVD player, while listening to the audio of the DVD, This is a case where map information is displayed on the display.

  By the way, as described above, when the DVD player is playing but outputting only audio, when the DVD video transitions from the main screen to the menu screen, the map information from the navigation device is displayed on the display. Therefore, there is a problem that it is not known that the screen has been changed to the menu screen only by listening to the audio.

  In this case, in order to continue playback of the main part, it is necessary to operate the DVD player while viewing the menu screen. Therefore, the display on the display needs to be switched from the map information of the navigation device to the video of the DVD player. There is a drawback of noticing. There are several cases where the user operation is required during the playback of the DVD player other than when the menu screen is displayed as described above, and even if the DVD player requests the user operation, it cannot be dealt with.

  Patent Document 1 describes a car navigation device equipped with an optical disk device such as a DVD. When a vehicle is stopped, a moving image and sound are reproduced from a recording medium. An example of playing is described. When the reproduction of the recording medium is completed while the vehicle is traveling, the title menu screen is switched to determine the next reproduction mode, and the content of the operation is switched.

However, in Patent Document 1, the end of reproduction of a recording medium is detected and the menu screen is switched. For this reason, in the case of a recording medium in which playback processing continues (for example, music continues to flow as BGM even in the operation input mode) even if the operation input mode requires user operation during playback. Has a drawback that it is difficult to know only by voice / music that the user has switched to the operation input mode because the reproduction is not finished. In particular, in the case of a recording medium through which voice / music flows during the operation input mode, there is a problem that the user hardly notices only by changes in the voice and music before and after the operation input mode.

When the audio information from the DVD player 20 is reproduced, an audio guide signal is output from the navigation device 10. Can be mixed and output.

  The system controller 60 controls the operation of each unit, and is composed of a microprocessor including a CPU. The system controller 60 controls the navigation device 10, the DVD player 20, the display controller 30 and the like in response to an instruction input from the operation unit 70. . The operation unit 70 is a remote controller (remote controller) or an operation button disposed near the display 40 and is operated by a user.

  Next, the operation of the display device of the present invention will be described with reference to FIGS.

  In the present invention, as a display form on the display 40, for example, when the vehicle is stopped, video information from the DVD player 20 can be selected to watch a movie or the like. Of course, the map information from the navigation device 10 can be displayed to check the map and the current position.

  On the other hand, when the vehicle is running, the driver cannot view the video information from the DVD player 20, so that only the audio information is displayed without displaying the video information from the DVD player 20. Or the audio information from the DVD player 20 is supplied to the speaker 50 to display the map information from the navigation device 10.

  In the present invention, as described above, when the DVD player 20 is playing back but outputs audio information only to the speaker 50 and the display 40 displays map information, the DVD video is the main screen. It is characterized in that it is possible to instantly confirm that the screen has changed to the menu screen. That is, when transitioning to the menu screen, it is necessary to operate the DVD player 20 while viewing the menu screen in order to continue playback of the main part, and in order to inform the user (driver) of that fact, transition to the menu screen is made. Sometimes, the system controller 60 detects the transition, and the display 40 is switched from the map information to the video information of the DVD 21 and displayed. Or it switches so that the video information and map information of DVD21 may be displayed on a multi-screen simultaneously.

  Further, not only the transition to the menu screen, but also when the DVD player 20 transitions to another playback mode that requires the user's operation, the display on the display 40 is switched from the map information to the video information on the DVD 21 and displayed. To do.

  This is shown in FIG. 3A shows a first mode in which the map information from the navigation device 10 is displayed on the display 40, and the DVD player 20 is reproducing but outputting only audio information. On the other hand, when the DVD player 20 transitions to a playback mode that requires user operation, for example, a menu screen, the video information from the DVD player 20 is displayed on the display 40 as shown in (b1), or (b2). In this way, the video information from the DVD player 20 and the map information from the navigation device 10 are combined and switched to the second mode for multi-screen display. In addition, in (b2), the example of two screen juxtaposition is shown as a form of multi-screen display, but either one of the screens may be displayed as a sub screen display.

  Thus, the user can know that the DVD player 20 needs the user's operation by changing the display content of the screen. Thereby, the user can shift to display of the next reproduction screen by operating the operation unit 70 after stopping the vehicle or waiting for an opportunity such as a stop by a red signal. Then, after the operation, the map information is displayed on the display 40 as shown in (c), and the DVD player 20 is switched to return to the first mode in which only the audio information is output during reproduction.

  FIG. 4 shows an example of a playback mode in which the DVD player 20 requires a user operation. In FIG. 4, there are three possible playback modes that require user operation: menu, still, and bonus code. The menu mode includes VMGM and VTSM menus defined by the DVD-Video standard and AMGM menus defined by the DVD-Audio standard. VMGM is a top menu, and VTSM is a root menu of its lower layer, such as a chapter selection menu. AMGM is a voice-related menu.

  Still mode is defined by the DVD-Video standard. For example, a still image having selection items is displayed in a moving image, and a bonus code mode is defined by the DVD-Audio standard. This is a case where a bonus track or a bonus song is reproduced by inputting a password.

  FIG. 5 is a diagram for explaining an example of the transition of the playback state in the DVD player 20. When the playback screen of the main part is composed of a plurality of chapters PTT_1 to PTT_N, the playback is performed sequentially from the first chapter PTT_1, and finally. When the chapter PTT_N is reproduced, the display transitions to the menu (VMGM / VTSM) display screen to return to the main part. When the user gives a selection instruction while the menu screen is displayed, the video of the main part is again reproduced sequentially from the first chapter. Therefore, the screen is played back cyclically. In some cases, when the last chapter PTT_N has been played back, it may be in a stopped state (STOP), but this is a rare example.

  FIG. 6 shows an operation flowchart by the system controller 60. In FIG. 6, when the reproduction of the main part on the DVD 11 is completed and the return operation to the main part is started again (START), it is determined whether or not the menu mode is set in step S1. If it is not the menu mode (NO), the process proceeds to step S2 to determine whether or not it is the still mode. If it is not the still mode, the process proceeds to step S3 and it is determined whether or not it is the bonus code mode.

  If it is determined in step S1 that the menu mode is selected (YES), it is determined in step S4 whether or not the user operation is performed within a predetermined time. If there is a user operation, the user designates in step S5. A location search is performed.

  If there is no user operation within the predetermined time in step S4 (NO), it is determined whether or not there is an automatic transition command recorded on the DVD 21 in step S6. If there is a command (YES), the process proceeds to step S5, and a transition is made to automatically reproduce a predetermined screen according to the command. If there is no automatic transition command in step S6 (NO), the current button position (for example, “play main part” button on the menu screen) is selected in step S7, and the process proceeds to step S5 to search for a designated portion. .

  In step S8, the display controller 30 is controlled to switch to display the map information from the navigation device 10, and the audio information from the DVD player 20 is reproduced. Thereby, the return to the main part is completed (END).

  If it is determined in step S2 that the still mode is selected, it is determined in step S9 whether or not a user operation is performed within a predetermined time. If there is a user operation (YES), a user designation is performed in step S10. A search is made for the location. If no user operation is performed within the predetermined time in step S9 (NO), the process proceeds to step S11 to determine whether or not there is a selection button.

  In the still mode, a still image is displayed in order to select a screen to be advanced next in the moving image. Normally, there is a selection button (YES), and the process proceeds to the next step S12, where the current button position (for example, A and B) is selected. Is selected), the process proceeds to step S10, and the designated portion is searched. In rare cases, there is no selection button. In this case, the process proceeds from step S11 to step S13, waits for an operation of the reproduction continuation process (for example, a PLAY operation), and then proceeds to step S10 to search for a designated portion.

  In step S8, the display controller 30 is controlled to switch to display the map information from the navigation device 10, and the audio information from the DVD player 20 is output. This completes the return to the main part.

  Furthermore, if it is determined in step S3 that the mode is a bonus code mode (YES), it is determined in step S14 whether or not a user operation has been performed within a predetermined time, and if there is a user operation (in this case, the password is changed). If there is an input), the process proceeds to step S15, where a search is made for a location designated by the user.

  If there is no user operation within a predetermined time in step S14 (when no password is input), the process skips forward to the next track or the next song in step S16, and moves to step S15 to specify Search for a location.

  In step S8, the display controller 30 is controlled to switch to display the map information from the navigation device 10, and the audio information from the DVD player 20 is output. This completes the return to the main part.

  If it is determined in step S3 that the mode is not the bonus code mode, the process proceeds to an end step (END) and the reproduction of the main part is continued.

  As described above, in the display device of the present invention, only the audio information is output from the speaker 50 while the DVD player 20 is playing back, and the map information from the navigation device 10 is displayed on the display 40. When a transition is made to a playback mode that requires user operation during playback of the main part on the DVD player 20, the transition is detected and the display mode of map information by the navigation device 10 is automatically changed to the display of video information by the DVD player 20. Switch to inform the user. After the user operation, the original display mode is restored. Further, when there is no user operation within a predetermined time, a preprogrammed process is performed to automatically switch to the original mode, so that the user switching operation can be omitted.

  The present invention is not limited to the above description, and various modifications can be made without departing from the scope of the claims.
