The term “accumulate” is defined as storing file casting content in a portable terminal or in an external storage medium connected to the portable terminal.

  As for the file casting content, the user reproduces and views the content that has been stored on the mobile terminal. The streaming content can be viewed at the broadcast time, or the content recorded in advance can be played back and viewed. Some content is free and some content is paid. Also, for both file casting and streaming, the broadcast time is predetermined.

  Further, in mobile multimedia broadcasting, the mobile terminal can acquire a recommendation list from a recommendation server on the communication side by communication. The mobile terminal recommends content to the user by displaying a recommendation list. Here, the communication means that the mobile terminal receives a radio wave transmitted via the mobile communication network. In addition, the recommended list contains recommended content.

  FIG. 1 shows an overview of mobile multimedia broadcasting.

<Operation of recommendation server>
FIG. 16 is a flowchart illustrating an example of the operation of the recommendation server 300.

The recommendation server 300 determines whether a terminal log has been acquired from the mobile terminal 200 _n (step S1602). For example, the wireless communication processing unit 301 determines whether a terminal log from the mobile terminal 200 _n is input.

  If it is determined that the terminal log is not input (step S1602: NO), the process returns to step S1602. Until the terminal log is input, the process of determining whether the terminal log is input is continued.

When it is determined that the terminal log has been input (step S1602: YES), the recommendation server 300 determines whether the correspondence between the mobile terminal model and the user ID has been updated (step S1604). For example, the wireless communication processing unit 301 determines whether the correspondence between the user ID to be acquired together with the terminal log and IMEI is different from the model / user ID correspondence table to be managed by the wireless communication processing unit 301. judge. Further, when the user ID and IMEI are transmitted by the mobile terminal 200 _n , the wireless communication processing unit 301 manages the correspondence between the transmitted user ID and IMEI by the wireless communication processing unit 301. It may be determined whether it is different from the model / user ID correspondence table.

  If it is determined that they are different (step S1604: YES), the recommendation server 300 updates the model / user ID correspondence table (step S1606). For example, the wireless communication processing unit 301 updates the model / user ID correspondence table based on the correspondence between the user ID and the IMEI that should be obtained together with the terminal log obtained in step S1602.

  After the model / user ID correspondence table is updated in step S1606, and when it is not determined that the model / user ID correspondence table is different in step S1604 (step S1604: NO), the recommendation server 300 determines the model / content / codec based on the viewing log. A correspondence table is created (step S1608). For example, the wireless communication processing unit 301 creates a viewing log based on the terminal log and inputs it to each terminal information management unit 303. Each terminal information management unit 303 obtains the correspondence between the model of the mobile terminal and the content ID of the content viewed by the mobile terminal based on the viewing log to be input by the wireless communication processing unit 301, Input to the table management unit 308. The model corresponding codec table management unit 308 is based on the correspondence between the model of the portable terminal, the content ID of the content viewed by the portable terminal, and the metadata to be input by the wired communication processing unit 306. Create model / content / codec correspondence table.

  The recommendation server 300 performs recommendation calculation (step S1610). For example, the recommendation calculation unit 305 is used when selecting the content to be recommended based on the terminal log to be input from the wireless communication processing unit 301 and the metadata to be input by the wired communication processing unit 306. Find the indicator.

  The recommendation server 300 creates a recommended primary list (step S1612). For example, the recommended primary list creation unit 304 creates a recommended primary list by selecting the content to be recommended based on the recommendation calculation result to be input by the recommendation calculation unit 305.

  The recommendation server 300 sets the identification number i of the content included in the content primary list to 1 (step S1604). For example, the recommendation list creating unit 302 sets the identification number of the content included in the recommended primary list to be input by the recommended primary list creating unit 304 to 1.

  The recommendation server 300 determines whether i <N + 1 is satisfied (step S1616). Here, N represents the recommended primary list length. In other words, it may be the number of contents included in the recommended primary list.

  If it is determined that i <N + 1 is not satisfied (step S1616: NO), a recommendation list is transmitted (step S1618). For example, the recommendation list creation unit 302 inputs a recommendation list to the wireless communication processing unit 301. The wireless communication processing unit 301 transmits the recommendation list from the recommendation list creation unit 302 to the mobile terminal. For example, you may make it transmit in response to the recommendation request | requirement for acquiring the recommendation list | wrist from a portable terminal.

  When i <N + 1 is determined (step S1616: YES), it is determined whether the codec of the i-th content included in the recommended primary list is compatible (step S1620). For example, the recommendation list creation unit 302 is a codec in which the codec of the i-th content among the contents included in the recommended primary list can be supported by the mobile terminal that provides the recommendation list based on the model / codec correspondence table. Determine if it exists.

  If it is not determined in step S1620 that the content is supported (step S1620: NO), the i-th content is deleted from the recommended primary list (step S1622). For example, if the codec of the i-th content among the contents included in the recommended primary list is not included in the codec that can be supported based on the model / codec correspondence table, The i-th content is deleted from the primary list.

  If it is determined in step S1620 that it is compatible (step S1620: YES), and after the i-th content is deleted from the content primary list in step S1622, i is incremented by 1 (step S1624), and step S1616 is performed. Return to. For example, the recommendation list creation unit 302 increments i representing the content identification number by one.

<Operation of mobile terminal>
FIG. 17 is an example of a flowchart showing the operation of the mobile terminal 200.

  The mobile terminal 200 determines whether a recommendation acquisition request has been received from the user (step S1702). The determination may be performed regularly or irregularly. For example, information indicating a recommendation acquisition request is input to the UI control unit 207 when a user operates an operation unit (not shown). The UI control unit 207 determines whether or not the recommendation acquisition request is input.

  If it is determined that a recommendation acquisition request has been input (step S1702: YES), the mobile terminal 200 transmits a recommendation acquisition request to the recommendation server 300 (step S1704). For example, the UI control unit 207 inputs a recommendation acquisition request to the terminal log management unit 208. The terminal log management unit 208 inputs a recommendation acquisition request to the communication processing unit 205. The communication control unit 205 wirelessly transmits a recommendation acquisition request from the terminal log management unit 208 to the recommendation server 300.

  The mobile terminal 200 receives the recommendation list transmitted by the recommendation server 300 in response to the recommendation acquisition request (step S1706). For example, the communication processing unit 205 receives a recommendation list from the recommendation server 300.

  The mobile terminal 200 displays the recommendation list on the display screen (step S1708). For example, the communication processing unit 205 inputs a recommendation list from the recommendation server 300 to the recommendation information management unit 204. The recommendation information management unit 204 inputs recommended content information included in the recommendation list from the communication control unit 205 to the UI control unit 207. The UI control unit 207 controls to display the recommended content information from the recommendation information management unit 204 on the display screen.

  If it is determined in step S1702 that a recommendation acquisition request is not input (step S1702: NO), the mobile terminal 200 determines whether or not the next terminal log upload time has come (step S1710). For example, the next terminal log upload time may be transmitted from the recommendation server 300. The next terminal log upload time is received by the communication processing unit 205 and input to the terminal log management unit 208. The terminal log management unit 208 determines whether or not the next terminal log upload time has come based on the date and time information managed by the terminal device.

  When it is determined that the next terminal log upload time has come (step S1710: YES), the mobile terminal 200 transmits the content storage state and the terminal log to the recommendation server 300 (step S1712). For example, the terminal log management unit 208 inputs the content storage state to be input from the content management unit 202 and the terminal log to the communication processing unit 205. The communication processing unit 205 transmits the content storage state and the terminal log input by the terminal log management unit 208 to the recommendation server 300. Thereafter, the process returns to step S1702.

  If it is determined that the next terminal log upload time is not reached (step S1710: NO), the process returns to step S1702.

  According to this embodiment, it is possible to create a correspondence between a model and a codec that can be supported by the model from the viewing log for each model of the mobile terminal. Based on this correspondence, when a content list is provided to the mobile terminal, content using a viewable codec can be selected. Since a content using a viewable codec can be selected when providing the content list, the content acquired according to the content list can be played back and used on the mobile terminal.

  Since each mobile device can recommend content that can be played back and used, content that uses codecs that are not supported by mobile devices is not saved, so the memory of the mobile device is under pressure. Can be prevented. Further, since content using a codec that is not supported by the mobile terminal is not recommended, it is possible to prevent the user from being stressed.

  In this embodiment, a table in which a mobile terminal and a codec that can be supported by the mobile terminal are associated with each other is created, and based on the table, content that can be supported by the mobile terminal that is the provision destination of the recommendation list is selected. You may do it.
