  As illustrated, the information terminal 100 includes a storage unit 101, a detection unit 102, a determination unit 103, a transmission unit 104, and an ID determination unit 105. Hereinafter, the function of each means will be described.

  The storage unit 101 transmits an ID for the information terminal 100 (hereinafter referred to as “ID for own terminal”), an ID for identifying the memory card 210 inserted into the other terminal 200 as another, and the other terminal 200. Information associated with the data to be stored is stored. FIG. 2 is a diagram for explaining information stored in the storage unit 101.

  The storage unit 101 stores, for example, a table as shown in FIG. 2A as information associated with “ID for own terminal”. In this case, data to be transmitted to a terminal in which the memory card is inserted is associated with a certain memory card ID. In FIG. 2A, the data A and B to be transmitted may be the same.

  The data to be transmitted will be described. In the present embodiment, the data to be transmitted is, for example, control information including a content and a command on how to reproduce the content on a transmission destination terminal as shown in FIG. For example, the content includes, for example, a plurality of still images, and the control information is for performing a slide show of these. As shown in the figure, it may include moving images, audio data, and the like. In this case, the control information may be such that the image data is sequentially reproduced while reproducing the audio data during the slide show.

  The ID for the own terminal will be described. The ID for the own terminal is identification information for identifying the data transmission source in the data transmission according to the present embodiment. The identification information of the information terminal 100 itself may be used, but is not limited to this. In this embodiment, the ID of the memory card 110 inserted into the information terminal 100 itself is assumed. When the memory card 110 is inserted, the information terminal 100 reads the ID from the memory card 110 and manages it as an ID for the terminal itself. If the ID for the own terminal is configured as the ID of the memory card inserted into itself, the user on the transmission side can execute the data transmission of this embodiment with any information processing apparatus as long as the memory card is carried around, There is an effect that the portability of the data transmission service according to the present embodiment is increased.

  Returning to FIG. 1, the detection means 102 has a function of detecting that the memory card 210 has been inserted into the other terminal 200. In this embodiment, VPN and DLNA (Digital Living Network Alliance) are established between the information terminal 100 and the other terminal 200, and the detection means 102 uses the UPnP (Universal Plug and Play) to An event that a memory card 210 is inserted into 200 is detected. The detecting unit 102 determines whether or not an ID is assigned to the memory card 210. If the ID is assigned, the detection unit 102 entrusts the subsequent processing to the determining unit 103. Entrust to 105.

  The determination unit 103 refers to the information associated with the ID for the own terminal stored in the storage unit 101, and determines whether the ID of the inserted memory card 210 corresponds to the ID for the own terminal. . In the case of correspondence, information indicating which data is to be transmitted corresponding to the ID of the inserted memory card 210 is sent to the transmission means 104.

  The transmission unit 104 transmits data associated with the ID of the memory card to the other terminal 200 based on the determination of the determination unit 103. The transmission unit 104 also transmits the ID of the memory card determined by the ID determination unit 105 to the other terminal 200.

  When the detection unit 102 inserts a memory card with no ID assigned to the other terminal 200, the ID determination unit 105 determines the ID of the memory card. Further, the ID determination unit 105 associates the determined ID of the memory card with the ID for the own terminal, and stores the association information in the storage unit 101. At this time, information on data to be transmitted may also be associated. The ID determination unit 105 sends the determined memory card ID to the other terminal 200 via the transmission unit 104 and causes the memory card 210 to write the ID.

  The information terminal 100 can use, for example, an information processing apparatus such as a personal computer as hardware, and each of the components described in the figure can be obtained by the cooperation of a program that uses such hardware and the hardware. It can function as a means.

  The other terminal 200 only needs to have a communication function and a function capable of reading and writing the memory card 210. For example, a personal computer, a photo frame, a network-compatible television, or the like can be used. Further, when the other terminal 200 receives the ID determined by the ID determination means 105 from the transmission means 104 of the information terminal 100 when a memory card without an ID is inserted, the other terminal 200 stores the ID in the memory card. Write. On the other hand, when a memory card with an ID is inserted, an event that the memory card has been inserted is notified to another terminal connected by VPN using UPnP together with the ID of the memory card. 100 receives data transmission.

  The data transmitted to the other terminal 200 may be stored in the memory card 210, or may be stored in a storage medium (not shown) built in the other terminal 200. The other terminal 200 preferably has means for automatically reproducing the content received from the information terminal 100 based on the control information included in the data. By configuring the received data to be automatically played back, there is an effect that the content can be easily used even when the user of the other terminal 200 is unfamiliar with the operation of the information device, for example.

  The memory cards 110 and 210 may be any removable computer-readable recording medium, and are not limited to being in the form of a card. For example, a stick shape may be used. Hereinafter, the processing flow of the entire embodiment will be described.

First, the preprocessing will be described, and then data transmission (steps S109 to S114) according to the present embodiment will be described.

  First, the information terminal 100 determines an ID for its own terminal (step S101). In the present embodiment, as described above, the ID is read from the inserted memory card 110 and set as the ID for the own terminal. Instead of using the ID of the memory card, the ID may be generated by the own terminal and written to the memory card 110.

  Next, the information terminal 100 creates control information for data to be transmitted to the other terminal 200 (step S102). Note that step S102 may be performed before step S101 or simultaneously.

  Next, a process for establishing a VPN between the information terminal 100 and the other terminal 200 is performed (step S103). The subsequent processing (steps S104 to S114) is performed in a state where the VPN is established.

  When the memory card (ID undecided) 210 is inserted by an operation by the user of the other terminal 200 (step S104), the detection unit 102 detects the memory card 210 using UPnP (step S105). Since the memory card 210 has not yet been assigned an ID, the ID determining means 105 determines the ID (step S106), and the determined ID is sent to the other terminal 200.

  The other terminal 200 writes the transmitted ID in the memory card 210 (step S107). On the other hand, the information terminal 100 stores the association between the ID of the memory card determined by the storage unit 101 and the ID for the own terminal (step S108). Note that step S106 and step S108 may be performed simultaneously.

Data transmission according to the present embodiment is performed in the following procedure.
When the memory card (ID determined) 210 is inserted by an operation by the user of the other terminal 200 (step S109), the detection unit 102 detects the memory card 210 using UPnP (step S110). Next, it is determined whether or not the ID of the memory card 210 detected by the determination means 103 corresponds to (or is associated with) the ID for the own terminal (step S111). Is transmitted to the other terminal 200 (step S112).

  The other terminal 200 receives the transmitted data (step S113), writes this data to the memory card 210 or a storage means (not shown), and reproduces the content based on the control information included in the data (step S114). ).

  If the data to be transmitted has been updated, the receiving user may perform an operation such as inserting or removing the memory card 210 once again to cause the processing in steps S109 to S114 to be performed again.

  According to the present embodiment described above, data can be transmitted by a simple operation of simply inserting a memory card at a receiving terminal, so that content can be transmitted and received by performing a simple operation. . In addition, if control information is included in transmission data and the reception side reproduces the control information, even if the user of the other terminal 200 is unfamiliar with the operation of the information device, for example, the content can be easily used. it can.

  In addition, when the ID for the own terminal is configured as the ID of the memory card inserted into itself, the user on the transmission side can execute the data transmission of this embodiment regardless of the information processing apparatus as long as the memory card is carried around. Thus, the portability of the data transmission service according to the present embodiment is enhanced.
