  The vehicle terminal device 3 is an information processing device installed in a vehicle such as a train or a bus, and has a positioning (position detection) function of the vehicle, a data communication function via the communication network 4, and the like.

  Next, the operation of the information distribution system will be described with reference to FIGS. FIG. 3 is a flowchart showing the operation of the information distribution system according to the embodiment of the present invention. FIG. 4 is a flowchart showing the location information management operation in the server device.

  When the user of the user terminal device 2 who gets on a train, a bus or the like desires content distribution and needs a signal to get off, the user terminal device 2 transmits vehicle information and an information distribution request to the server device 1 together with the user ID (step). S11). The vehicle information is information on the boarded vehicle and information on the place of getting off, and for example, information such as “boarding station: XX station xx hour ΔΔ departure, getting off station: □□ station” is transmitted. The information distribution request is a distribution request for content information selected by the user, such as information related to the getting-off area or information based on the user's preference.

  Receiving the vehicle information and the information distribution request from the user terminal device 2, the server device 1 authenticates the user ID and starts managing the position information of the vehicle (step S12). That is, it requests the corresponding vehicle terminal device 3 to sequentially transmit the position information based on the vehicle information from the user terminal device 2.

  That is, as shown in FIG. 4, the server device 1 requests the vehicle terminal device 3 to acquire vehicle position information (step S <b> 40), and the vehicle terminal device 3 that has received the request starts acquiring position information. (Step S41). And it repeats acquiring position information sequentially and transmitting the position information of the vehicles concerned to server device 1 (Steps S42-S45). Note that the server device 1 may access the corresponding vehicle terminal device 3 every predetermined time to obtain the position information of the vehicle. The server device 1 requests the vehicle terminal device 3 to stop the acquisition of the position information when the vehicle approaches the user's planned departure place (step S46), and the vehicle terminal device 3 stops the acquisition of the position information. And the notification to the server apparatus 1 is complete | finished (step S47).

  On the other hand, the server device 1 starts distributing the content information requested from the user terminal device 2 (step S13). That is, the control unit 16 of the server device 1 sequentially transmits the content information 14 (for example, content information encoded in units of 3 minutes) created by the streaming data creation unit 11 and stored in the storage unit 12 to the user terminal device 2. Stream it. In the user terminal device 2, the content distributed by streaming is reproduced by the display unit 23 and the speaker 28.

  The vehicle position information management is performed by determining whether or not the vehicle position information has been updated based on the position information from the vehicle terminal device 3 in step S14.

  If the vehicle position information is updated, the server device 1 determines the approach of the vehicle position information and the exit location (arrival location) requested by the user of the user terminal device 2 within a predetermined range (step S15). If not approaching yet, the process returns to step S14. The getting-off information may be time information, and the approach to the getting-off place (arrival place) may be determined based on the getting-off time.

  Next, the remaining time of the content information being distributed is calculated (step S16). Further, it is determined whether or not the distribution is completed before arrival at the disembarking place (step S17). When the distribution is completed, the content is continuously distributed (step S18). Thereafter, if the arrival location is closer, the server device 1 outputs a getting-off signal (for example, that it is an arrival location soon) to the user terminal device 2 (step S25). This getting-off signal may be displayed on the display unit 23 like audible display or telop, for example. Moreover, it is only necessary to end the content and not to display the getting-off signal.

  On the other hand, if the distribution does not end before arrival, it is determined whether or not the undistributed content information is a predetermined time or more, or the undistributed content information is a predetermined ratio or more (for example, the undistributed content is 10% or more of the whole). (Step S19). If it is a predetermined time or a predetermined ratio or more, bookmark information of content information being distributed (viewed information of the content) is generated (step S20). Thereafter, the distribution of the content information is terminated (step S21), the generated bookmark information is transmitted to the user terminal device 2 (step S22), and the process proceeds to step S25.

  In other words, the control unit 16 of the server device 1 indicates, as bookmark information, information indicating how much of the distributed content information has been viewed (information indicating how far the content information encoded in a predetermined time unit has been distributed). When the user of the user terminal device 2 wants to continue to view the content information by generating the data and transmitting it to the user terminal device 2, the bookmark information is transmitted to the server device 1 to transmit data after viewing To be able to receive.

  If the undelivered content information is less than a predetermined time or the undistributed content information is less than a predetermined ratio (for example, less than 10% of the undistributed content), the partial content information of the content information being distributed is It deletes and thins out (step S23), transmits to the user terminal device 2 (step S24), and proceeds to step S25.

  That is, the control unit 16 of the server device 1 does not distribute at least a part of the content information encoded in the remaining predetermined time unit for the content information being distributed (for example, every other content information). (Distribute information in units).

  Note that the setting in the case where the distribution does not end before arrival may be performed by the user's prior setting of the user terminal device 2. This setting may be arbitrarily set in advance based on the content type to be distributed (moving image, music, text, game, etc.). For example, settings for inserting or thinning bookmarks may be made effective for moving image content, and settings may be made for discontinuing distribution for other content (music, online games, etc.).

  In the present embodiment, the position information of the user terminal device 2 is obtained by positioning by the vehicle terminal device 3, but may be calculated by the positioning function (GPS function) of the positioning unit 22 of the user terminal device 2. . That is, the server apparatus 1 may receive position information from the user terminal apparatus 2 in order, update and manage the position information, and determine approach to the getting-off place (arrival place).

  In the above description, information distribution by streaming is premised. For example, when the user terminal device 2 outputs content information stored in advance, the getting-off information transmitted from the server device 1 via the wireless communication unit 21 is used. It may be controlled to change the output of the content information by comparing the scheduled departure time based on the received information and the remaining time information of the content information being processed. That is, as described above, control such as thinning out of content, notification of bookmark information, and end of content reproduction may be performed.

  Further, there may be a plurality of contents to be distributed, and control may be performed so as to change the output of the content information with respect to the contents reproduced when approaching the getting-off place.
