  The configuration and function of the mobile device 20 according to the present embodiment have been described above. Next, a display method by the mobile device 20 according to the present embodiment will be described with reference to FIG.

  FIG. 12 is a flowchart showing a flow of a display method by the mobile device 20 according to the present embodiment. First, the playback unit 250 of the mobile device 20 starts playback of content data in response to a content data playback instruction from the user (S504). Subsequently, the display screen generation unit 224 of the mobile device 20 generates an evaluation screen for the content data being played in response to an instruction to generate the evaluation screen by the user (S508).

  Subsequently, the setting unit 240 of the mobile device 20 determines whether or not the selection operation instructing the content data evaluation setting is detected by the selection operation detection unit 236 (S512). When the setting unit 240 determines that the selection operation is detected by the selection operation detection unit 236, the setting unit 240 sets the evaluation of content data based on the selection operation (S516). On the other hand, when the selection operation detection unit 236 determines that the selection operation has not been detected, the display screen generation unit 224 evaluates the content data after the change of reproduction when the content data reproduced by the reproduction unit 250 is changed. A screen is generated, and the process returns to S512 (S520, S524).

  When the content data reproduced by the reproducing unit 250 has not been changed, the display switching unit 248 determines whether or not the switching operation detecting unit 244 has detected a switching operation instructing switching of the evaluation screen (S528). If it is determined that the switching operation for instructing the switching of the evaluation screen has not been detected, the process returns to S512.

  On the other hand, if it is determined that a switching operation for instructing switching of the evaluation screen has been detected, the display screen generation unit 224 searches for content data in the display target range (S532). Here, the display target range may be a content data group corresponding to metadata having the same upper node as the metadata corresponding to the currently displayed evaluation screen in the data structure shown in FIG. For example, when the currently displayed evaluation screen corresponds to “World Period” 442, the display target range includes “Past” 444, “Past” 444, which has the upper node “Five Dimension” 424 of “World Period” 442 as an upper node. Cross line "446 is included.

  That is, the display target range is determined by how the content data corresponding to the evaluation screen is selected. For example, even if the same content data “Tobiuma Rider” is selected through “All songs” 410, “Akashi” 418 having “All songs” 410 as an upper node is included in the display target range. When selected through “Playlist” 416 and “Playlist 1”, “Cross Line” 458 having “Playlist 1” 436 as an upper node is included in the display target range. According to this configuration, it is possible to further improve the efficiency of content data evaluation work by the user.

  The upper node is not limited to a node one level higher than the metadata corresponding to the currently displayed evaluation screen, and may be a node higher than two levels of the metadata of the displayed content data. For example, when the currently displayed evaluation screen corresponds to “Past” 464, the display target range includes “Akashi” 462 whose upper node is “Misters” 430, which is two layers above “Past” 464, Content data corresponding to metadata arranged in a lower order such as five dimensions “450” and “above” 452 may be included.

  That is, the metadata group having the same node in the upper hierarchy is stored in the storage unit 220 as the same category, and the display target range is the metadata included in the category to which the metadata corresponding to the currently displayed evaluation screen belongs. Corresponds to the group.

  Subsequent to the processing of S532, the display screen generation unit 224 generates an evaluation screen for content data within the searched display target range (S536). Then, the reproduction control unit 260 causes the reproduction unit 250 to reproduce the content data corresponding to the newly generated evaluation screen, and returns to the process of S512 (S540).

  As described above, when the evaluation screen for one content data is displayed, the mobile device 20 according to the present embodiment simply switches the displayed evaluation screen, and the other content data evaluation screen is displayed. Can be switched to. Therefore, in the mobile device 20 according to the present embodiment, the user can easily perform the setting operation for evaluating a plurality of content data.

  In the mobile device 20 according to the present embodiment, the content data reproduced by the reproduction unit 250 and the content data to be evaluated by the evaluation screen generated by the display screen generation unit 224 are the same. The user can efficiently set the evaluation of the content data while viewing the content data to be reproduced and confirming the content data.
