Part 80.

  FIG. 3A is a plan view schematically showing the arrangement of the display in the vehicle, and FIG. 3B is a side view thereof. FIG. 4 is a diagram illustrating a specific configuration example of the media source in the display system. As shown in FIG. 3, five displays 100, 110, 112, 120, and 122 are installed in the passenger compartment, and the front display 100 and the left and right sides of the first rear seat are placed in front of the driver seat and the passenger seat. And displays 120 and 122, respectively, on the left and right sides of the second rear seat.

  Media sources also include a radio receiver 200, a CD player 202, a system unit 220 including a hard disk device 204 and a navigation device 206, a system unit 230 including a DVD player 208 and an external input 210, and a DVD changer 212. . As shown in FIG. 3B, the system unit 220 is installed on the front side, and the system unit 230 and the changer 212 are installed on the rear seat side. System units 220 and 230 and changer 212 are connected by an in-vehicle bus (not shown).

  Each of the displays 100, 110, 112, 120, and 122 is a flat type display, and can select a desired media source via the touch panel on the display or the input unit 30 and view the media.

  Next, the operation of the display system of this embodiment will be described with reference to the flowchart of FIG. In a state where the system power is turned off, each user selects a media source from the input unit 30. In response, the source selection unit 50 controls the selection of the media source, and the data of the selected media source is displayed. Displayed above.

  The system control unit 40 monitors the input of the input unit 30 (step S101), and checks whether there is an input requesting display of the usage status of the media source (step S102). For example, as shown in FIG. 6, video data 300 provided by the media source is displayed on the display screen, and as a touch panel type input button, a button 310 for requesting display of usage status and a display switching button 320 are displayed. A power ON / OFF button 330 is displayed.

  When a usage status display is input (step S102), the usage status determination unit 60 (see FIG. 2) determines from which display the input was made (step S103). Next, the usage status determination unit 60 checks the selection status of the media source in the source selection unit 50, and determines which display is using which media source (step S104). The determined result is stored in the memory 70 and output to the display control unit 80.

  The display control unit 80 displays the usage status of the media source of each display on the requested display based on the determination result of the usage status determination unit 60 (step S105).

  FIG. 7 shows an example of a matrix display of the usage status of the media source according to the present embodiment. In this example, a case is shown in which a usage status display is requested from the display 122 installed on the left side of the second rear seat. Matrix display, that is, in the vertical direction, all media sources of navigation device, radio receiver, CD player, hard disk device, DVD player, DVD changer, external input (AUX) are arranged, and in the horizontal direction the front And all displays 100, 110, 112, 120, 122 installed in the rear are arranged. The contents of the media used are shown in the column where each media source and each display intersect.

  For example, the front display 100 uses a navigation device 206. A “-” is displayed in a column where the navigation device and another display intersect, which means that it cannot be used or selected outside the display 100. The display 110 on the right side of the first rear seat indicates that the radio receiver is being used and “FM Tokyo” is being viewed as the media content. The display 112 on the left side of the first rear seat is using the DVD player and displays the jacket or title being viewed. Further, the display 120 on the right side of the second rear seat is using a CD player, and displays a jacket or a song title being viewed.

  The display 122 is displayed with a different contrast or the like in order to distinguish its own display from other displays (indicated by hatching in the drawing). The column of the display 122 includes an identification display 340 indicating that sharing with a media source being used in another display is possible, and a media source that is not used in any display and can be selected by the display 122. An identification display 350 is shown. For example, the hard disk device 204, the DVD changer 208, and the external input 210 are unused on any display, and can be used or selected on the display 122. The FM Tokyo being viewed on the display 110, the content of the DVD being viewed on the display 112, and the content of the CD being viewed on the display 120 can be shared on the display 122.

  By selecting and inputting the identification displays 340 and 350, it is possible to select a media source. This selection may be input by operating a cursor with a remote controller, or may be input from a matrix display by a touch panel method. If the input is a touch panel, touching the identification display 340 in the intersection column between the display 122 and the radio tuner will select the radio receiver on the display 122 and allow FM Tokyo to be viewed. If the intersection with the hard disk device is touched, the hard disk device is newly selected.

  Returning to the flowchart of FIG. 5 again, when the media source is selected from the matrix display as shown in FIG. 7 (step S106), the usage status determination unit 60 refers to the usage status of the memory 70 and selects the selected media. It is determined whether or not the source is used in another display (step S107).

  When the selected media source is in use on another display, the usage status determination unit 60 controls the source selection unit 50 so that the data of the selected media source is shared among a plurality of displays. Thereby, the display control unit 80 displays the data of one media source on a plurality of displays and shares the media source (step S108).

  On the other hand, when the selected media source is unused in any display, the usage status determination unit 60 controls the source selection unit 50 to connect the selected media source to the requested display (step S109). ). As a result, the display control unit 80 displays the menu screen of the selected media source on the requested display and puts it into a standby state.

  Thus, according to the present embodiment, each user can recognize at a glance the usage status of the media source by displaying in a matrix which media source each display is using. As a result, selectable media sources can be easily recognized and shared when interested in the media content that other users are viewing.

  In the above embodiment, the use status of the media source is displayed in a matrix, but other than this, for example, as shown in FIG. In this case, the seat position on the display may be displayed together. The example of FIG. 8A is an example in which a display of usage status is requested from the display 122 (left side of the second rear seat). The usage status is omitted, but of course, it may be added here. . Such a display allows the user to easily know the media sources that can be selected.

  Further, as shown in FIG. 8B, the usage status of the media source may be displayed together with the image diagram 400 schematically showing the installation status of the display in the vehicle interior. The user can intuitively grasp the display using the media source with reference to the image diagram 400.
