Instructs shuffle playback or the like. Further, the content operation unit 162 may display a jacket of the content being played back, an image related to the content being played back, or the like.

  The side bar 164 switches content display on the PC content display unit 166, and executes content exchange between the information processing apparatus 100 and the mobile terminal 200. For example, when “Music Library” in “Library” is selected with a mouse click or the like in the side bar 164, a list of music-related contents that can be played back by the information processing apparatus 100 is displayed on the PC content display unit 166. When “Music” under “Music Library” is selected, the content related to music is encoded by a compression method such as MP3 (MPEG Audio Layer-3), AAC (Advanced Audio Coding), ATRAC (Adaptive Transform Acoustic Coding), or the like. The music file thus extracted is extracted and displayed on the PC content display unit 166. Of course, it is also possible to select from the side bar 164 to display a list of all contents regardless of the type.

  The PC content display unit 166 displays a list of contents that can be played back by the information processing apparatus 100. The list of contents displayed on the PC content display unit 166 is changed by operating the side bar 164. The PC content display unit 166 displays content attribute information in a list format. Examples of content attribute information include content title, content playback time, content artist name, album name including the content, It may include the evaluation set by the user for the content, the size of the content, the registration date and time of the content in the information processing apparatus 100, the genre of the content, and the like. The attribute information of these contents is stored in the information processing apparatus 100, for example, the HDD 116 in the form of metadata.

  Then, when the mobile terminal 200 is connected to the information processing apparatus 100, the terminal capacity display unit 167 and the terminal content display unit 168 are displayed in order to view the content information stored in the mobile terminal 200. The The terminal capacity display unit 167 graphically displays the capacity of content stored in the mobile terminal 200 and the free capacity of the mobile terminal 200. At normal times, the terminal capacity display unit 167 displays a current capacity display unit 167a indicating the current capacity of the mobile terminal 200 in accordance with the ratio of the current capacity to the storable capacity of the mobile terminal 200. The display color of the current capacity display unit 167a may be, for example, light green. When no content is stored in the mobile terminal 200, the current capacity display unit 167 a is not displayed on the terminal capacity display unit 167.

  The terminal content display unit 168 displays a list of contents stored in a predetermined location of the mobile terminal 200, for example, the flash memory 217 of the mobile terminal 200. By displaying the content stored in the mobile terminal 200 on the terminal content display unit 168, the content stored in the mobile terminal 200 is managed, for example, the content is deleted or transferred to the information processing apparatus 100 be able to.

  Note that the jukebox program 160 may display the search character string input unit 163. When a search target character string is input to the search character string input unit 163 and a search is performed, content in which the character string and the title, artist name, album name, etc. partially match are searched for and displayed on the PC content display unit 166 in a narrowed manner. May be. In the case of searching, a list of contents that have been searched word by word and narrowed down in the PC content display unit 166 may be displayed, and after searching for all the words to be searched, the content that has been narrowed down to the PC content display unit 166 is searched. May be displayed.

  The screen of the jukebox program 160 displayed on the information processing apparatus 100 for use in the content transfer system 10 according to the embodiment of the present invention has been described above. Next, a capacity display method of the mobile terminal 200 according to an embodiment of the present invention will be described.

  FIG. 8 is a flowchart for explaining an overview of the capacity display method of the mobile terminal 200 according to the embodiment of the present invention. Hereinafter, the outline of the capacity display method of the mobile terminal 200 according to the embodiment of the present invention will be described with reference to FIG. When displaying the capacity of the mobile terminal 200, the mobile terminal 200 is connected to the information processing apparatus 100 in advance, and the information processing apparatus 100 acquires the total capacity and the free capacity that can be stored in the mobile terminal 200, It is assumed that content information stored in the portable terminal 200 is stored inside the information processing apparatus 100 (for example, the mobile device database 136).

  First, the PC content display unit 166 of the jukebox program 160 is operated by the user of the information processing device 100 to change the selection state of the PC content, or content is transferred from the information processing device 100 to the portable terminal 200 by the jukebox program 160. The setting for transferring changes (step S102). When the selection state or transfer setting of the PC content changes, the content management unit 128 via the user interface unit 120 and the application control unit 122 information on the content currently selected in the PC content display unit 166 of the jukebox program 160. Are collected (step S104). The user can grasp whether or not the content is in a selected state based on the background color of each row in which information of each content displayed on the PC content display unit 166 is displayed. For example, if the content is in the selected state, the background color of the row can be yellow, and if the content is not in the selected state, the background color of the row can be white.

  Here, the information collected by the content management unit 128 includes information necessary for calculating the expected post-transfer size of the content thereafter. Information necessary for calculating the expected size after transfer of content includes, for example, information such as the current data size of each selected content and the bit rate of the content. The content information collection method in step S104 will be described in detail later.

  When the information on the currently selected content is acquired in step S104, the post-transfer size calculation unit 124 predicts the content in the mobile terminal 200 after the currently selected content is transferred to the mobile terminal 200. The data sizes are added together (step S106). Details of the summation process of the predicted data size will be described later. When the summation of the predicted data size of the content is completed, the predicted data size after the transfer of the content is displayed on the jukebox program 160 via the user interface unit 120 (step S108). The display method of the predicted data size may be displayed graphically on the terminal capacity display unit 167 or may be displayed as text on a part of the jukebox program 160. Thus, when the content selected by the PC content display unit 166 is transferred to the mobile terminal 200 by displaying the predicted data size after transfer of the content to be transferred to the mobile terminal 200 on the screen, the mobile terminal 200 It is possible to grasp how much data size is 200.

  In step S108, when the predicted data size after content transfer is displayed on the jukebox program 160 via the user interface unit 120, the total capacity and the free capacity that can be stored in the portable terminal 200 are acquired. It is desirable. The total capacity and the free capacity of the mobile terminal 200 are acquired when the mobile terminal 200 is connected to the information processing apparatus 100. However, after that, a file may be added to or deleted from the portable terminal 200 by a program different from the jukebox program 160 or by directly operating the portable terminal 200. Therefore, when displaying the predicted data size after the content transfer, for example, the mobile communication management unit 132 sends an instruction to obtain the latest information to the mobile terminal 200, and the mobile terminal 200 provides the latest information on the capacity. It is desirable to obtain.

  The capacity display method for the mobile terminal 200 according to the embodiment of the present invention has been described above with reference to FIG. Next, a content information collecting method according to an embodiment of the present invention will be described.

  FIG. 9 is a flowchart for explaining the content information collecting method according to the embodiment of the present invention, and describes step S104 in FIG. 8 in detail. Hereinafter, a content information collecting method according to an embodiment of the present invention will be described with reference to FIG.

  First, the contents selected in the PC content display unit 166 of the jukebox program 160 are listed (step S112). When the content in the selected state is enumerated, a loop process that continues until the end of the enumerated content is started (step S114).

  Subsequently, for each of the listed contents, it is determined whether or not the same contents as the contents exist in the mobile terminal (step S116). Whether or not the same content exists in the mobile terminal 200 is determined by referring to the content information of the mobile terminal 200 stored in the mobile device database 136. In the present embodiment, the ID column in the mbjMirror table is searched with the ID column information in the mbjContent table corresponding to the listed content. As a result of the search, if there is content that matches the information in the ID string, it is determined that the content also exists in the mobile terminal 200.

  As a result of the determination in step S116, if it is determined that the same content does not exist in the portable terminal 200, the post-transfer size calculation unit 124 adds the content to the size calculation candidate (step S118). On the other hand, as a result of the determination in step S116, if it is determined that the same content exists in the mobile terminal 200, the post-transfer size calculation unit 124 does not add the content to the size calculation candidate.

  The determination process in step S116 is executed up to the end of the listed contents (step S120). When the determination process in step S116 is executed up to the end of the enumerated contents, the process ends.

  The content information collection method according to the embodiment of the present invention has been described above with reference to FIG. Next, a method for adding the predicted data size after content transfer according to an embodiment of the present invention will be described.

When the post-transfer size calculation unit 124 enumerates the content added to the size calculation candidates, a loop process that continues until the end of the enumerated content is started (step S124).

  Subsequently, for each of the listed contents, it is determined whether the contents are contents that require format conversion at the time of transfer (step S126). Whether or not the content requires format conversion is determined by determining whether or not the content is in a file format that can be played back on the mobile terminal 200. Also, even for the same content, depending on the model of the mobile terminal 200, there are models that require a change in bit rate and format, and models that can be transferred without changing the bit rate and format.

  As a result of the determination in step S126, if the content requires format conversion at the time of transfer, the post-transfer size calculation unit 124 predicts the data size after format conversion of the content based on the setting of the content conversion setting unit 126. (Step S128). As an example of a method for predicting the data size after format conversion, if the content is music data, the data size after format conversion is the playback time (seconds) of the music and the bit rate (bps after conversion). Bit per second) and adding the header size of the converted format. The header size of the format after conversion differs depending on the type of format to be converted. If the transfer destination device requires playback in a dedicated format, in addition to the converted format header size, the dedicated format header size is added to the converted data size. Also good.

  On the other hand, as a result of the determination in step S126, if the content does not require format conversion at the time of transfer, the current data size of the content is acquired (step S130).

  Then, the post-transfer size calculation unit 124 adds the data size predicted and calculated in step S128 or the data size acquired in step S130 to the predicted data size after transfer (step S132).

  The processes in steps S124 to S130 are executed up to the end of the listed contents (step S134). When the determination process in step S116 is executed up to the end of the enumerated contents, the process ends.
