When the travel time traveled by public transportation is shorter than the second threshold, the data transmission determination processing means determines that news data is not transmitted to a terminal device corresponding to public transportation, and the data creation processing means Does not create news data for the mobile phone 13.

  In the present embodiment, a terminal device is set corresponding to each moving means, a mobile phone 13 is set corresponding to walking, public transportation, etc., and a navigation device 14 is set corresponding to the vehicle. In creating the news data, the reproduction time setting processing means of the data creation processing means performs a reproduction time setting process, and a time for reproducing the news data based on the travel time for each of the moving means, That is, the playback time is calculated and set, and the data size calculation processing means of the data creation processing means performs data size calculation processing, calculates the data size of news data that can be played back based on the playback time, and The data selection processing means of the data creation processing means performs data selection processing and selects news data to be created based on the data size. Then, the news data is selected so that the time required for reproducing the news data, that is, the reproduction required time is sufficiently within the travel time for each moving means.

  In this way, news data is created only when the travel time traveled by a predetermined moving means is equal to or greater than a threshold value. For example, even if the travel time is shortened due to a change in traffic congestion on the road, etc. , Sufficient time for reproducing the news data can be secured. In addition, since news data is not transmitted before and after the timing of switching the moving means, for example, even if the switching guidance is given on the map screen formed on the display unit 35 (FIG. 2), the news data Will not interfere with the information notification screen.

  Therefore, the operator can surely acquire news data.

  In the present embodiment, since the route search processing is performed in the information center 45, the data creation processing means obtains the search route from the personal data database 64. When a search process is performed, the data creation processing unit acquires a search route from the navigation device 14. In that case, the navigation device 14 sets the starting point and the destination, but not only can the home be set as the starting point, but also the current location detected by the GPS sensor 15 can be set.

  In the present embodiment, the first and second threshold values are different from each other. However, the first and second threshold values can be made equal.

Step S43: It is determined whether or not the travel time traveled by the vehicle is greater than or equal to the first threshold value. If the travel time traveled by the vehicle is greater than or equal to the first threshold, the process proceeds to step S44. If the travel time traveled by the vehicle is smaller than the first threshold, the process proceeds to step S45.
Step S44: Create news data for the vehicle.
Step S45: It is determined whether or not there is an area for moving by public transportation. If there is an area to be moved by public transportation, the process proceeds to step S46, and if not, the process ends.
Step S46: It is determined whether or not the travel time traveled by public transport is equal to or greater than a second threshold value. If the travel time traveled by public transport is greater than or equal to the second threshold, the process proceeds to step S47. If the travel time traveled by public transport is less than the second threshold, the process ends.
Step S47 Create news data for the mobile phone 13 and terminate the process.
