The application acquisition destination information 107 indicates a program acquisition destination URL and the like. The metadata acquisition destination information 108 indicates an acquisition destination URL of the application metadata 100 and the like.

  The application can have at least four states of a widget mode, a long widget mode, a moving image coexistence mode, and a full screen mode. The widget mode is a mode that can be displayed in a fixed size on the widget list 84, displays only the service provided by the application, and cannot operate the service provided by the application. The long widget mode, video coexistence mode, and full screen mode are modes that allow you to operate the service provided by the application through the GUI screen as well as displaying the service provided by the application. The full screen mode displays the video. In the video coexistence mode, the application is displayed while continuing to display the video while splitting the screen, while in the long widget mode, the application is displayed in the display area of the widget list. Is a mode for displaying.

  The application metadata 100 includes information on whether or not each metadata has a function corresponding to each mode, whether or not the widget mode is present 109, the long widget mode is present 110, the moving image coexistence mode is present 111, and the full screen mode. It has as presence 112. It also has information on a default display mode 113 for designating a screen mode mainly used by default among the four modes.

  The application operation period 114 is designated when a plurality of activated applications are to be operated periodically, for example, to update the screen, and operation resources are allocated to the applications according to this period. The external storage permission 115 is information for designating whether or not an application can be stored in an external storage medium such as a removable medium. The storage capacity of the memory 12 and the storage 14 of the display device 50 can be saved.

  The CPU 13 performs processing such as application download, update, search, and position Iran display in accordance with these pieces of information.

  FIG. 13 is a configuration example of application license information. The license information 200 indicates information on a license form 201 such as whether it is sold out or rented, information on license conditions 202 such as application copying and usage count, information on a usage period 203 in the case of rental, and a license information acquisition server. The license acquisition destination information 204 includes information such as key information 205 for decrypting the application if the application is encrypted.

  For the licensed application, the content display device 50 monitors the conditions such as copying, the number of times of use, and the usage period in accordance with the license information 200, enables the application to operate within the conditions, and does not satisfy the usage conditions. In such a case, an error message indicating that the license has expired is displayed to the user, and the application is not operated. Also, a UI (User Interface) that prompts re-acquisition of the license may be presented.

  FIG. 14 is a display example of an application in the long widget mode activated from the widget state of FIG. 10, and the application operation screen 85 is displayed using the entire display area of the widget list.

  FIG. 15 is a display example of the application in the full screen mode, in which the moving image is deleted and the operation screen of the application is displayed on the full screen.

  FIG. 16 is a display example of the application 86 in the moving image coexistence mode, and the operation screen 87 of the application is displayed on the right half while the moving image is displayed on the left half.

  FIG. 17 is an operation flowchart of the application. The CPU 13 first determines the display mode of the activated application (1401), and if it is the full screen mode, erases the moving image (1402) and displays the application screen on the full screen (1403). In the moving image coexistence mode, the scaling of the moving image is changed to the size and position of the screen division state (1413), and the application screen is displayed in the remaining portion. In the long widget mode, the scaling state of the video is not changed, and the application screen is displayed in the widget list area.

  When the display is finished, the remote control operation is accepted (1404), the focus on the operation object displayed in the application screen is moved by the up / down / left / right cursor buttons (33, 34, 35, 36), and the Enter button 37 is selected. To operate the application. When the Menu button 41 is pressed, a menu for the application is displayed (1411), and operations such as termination or redisplay of the application, return of the screen, and advance can be performed (1412).

  When the application is terminated by the UI operation of the application, the screen returns to the widget list operation screen of FIG. 10, and another application can be selected and activated.

  Note that the application can also display and play back the moving image designated by the application on the application screen, separately from the moving image such as broadcasting. For example, even in the widget mode of FIG. 10, the application cannot be operated, but the application can automatically display the promotional video as the “MHK information” widget.

  Also, as shown in FIG. 14, a list of videos related to the main playback video such as broadcast is displayed, and the selected video is demo-played in a thumbnail state, and when the Enter button 37 is pressed, full-screen video playback is performed. There may be examples. In this case, the metadata server uses program information such as EPG attached to the main playback moving image such as broadcast or information such as title, broadcast station information, program ID, and genre code from the program metadata as a key. By executing the search for 62, it is possible to acquire the metadata of the moving image related to the main reproduction moving image, and display a list of moving images related to the application based on the metadata.

  In the full screen mode of FIG. 15, the moving image selected from the menu on the application screen 86 may be reproduced in the moving image display area 81 in the application screen. In the case of FIG. 16, the moving image selected from the menu on the application screen 87 may be reproduced as the main moving image 81. In addition, an application in which a plurality of screen modes are mounted may be able to change the screen state by operating the application. When an application is started from the application menu operation screen 83, an effective mode is selected from the full screen mode, the long widget mode, and the moving image coexistence mode for an application that does not have a widget mode according to the application metadata 100. It may be displayed and activated in the selected mode.

  Similarly, when an application is started on the widget list operation screen 84, the application metadata 100 is referred to, and an effective mode is selected and selected from the full screen mode, the long widget mode, and the video coexistence mode. You may start in mode. Further, when the default display mode 111 is designated on the application menu operation screen 83 and the widget list operation screen 84, the application is immediately displayed in the default designated display mode without displaying the screen mode choices to the user. Also good.

  In the case of an application having a license, the application may be automatically deleted on the application menu operation screen 83 and the widget list operation screen 84 when the expiration date specified by the license has passed or the application has been used as many times as possible. Or, instead of automatic deletion, an implementation is possible in which the display is left in a mask state in which activation operations other than deletion and relicensing cannot be performed.

  In addition, another example of the display form of the widget system is conceivable. As shown in FIG. 18, a banner display 82 is added outside the scaled moving picture display 81 without changing the aspect ratio, and the menu list correspondingly. An implementation form that reduces the display size of is also conceivable. In this case, there is an advantage that the area of the banner 82 can be used not only as video information but also as a widget operation guidance, error, and warning display area.

  According to the embodiment described above, the content display device 50 can effectively use the screen while displaying a moving image, and can easily select, start, and display an application with an operation device such as a remote controller. Can be improved.
