Roadside apparatus, control method and program

A distribution system comprising:

• a vehicle-mounted device configured to provide user taste information indicating how a user chooses contents information from a distribution enterpriser previously registered as a member;
• a server configured to organize and distribute contents information on the basis of a taste data setting table for setting the user taste information for each of items of contents data;
• and
• a roadside apparatus configured to intervene between the vehicle-mounted device and the server, which operates to receive uplink information including the user taste information reflected on the taste data setting table from the vehicle-mounted device entering a wireless communication area and to transmit the uplink information to the server, while transmitting information for the taste data setting table and version information for the taste data setting table from the server to the vehicle-mounted device,
• wherein the vehicle-mounted device operates to transmit the uplink information through the roadside apparatus to the server, when the contents information is the contents information from the member-registered distribution enterpriser,
• wherein the server operates to decide whether the taste data setting table reflecting the user taste information from the vehicle-mounted device is of the latest version when having received the user taste information from the vehicle-mounted device, and when the taste data setting table reflecting the user taste information from the vehicle-mounted device is not of the latest version, the server operates to generate the latest version of the taste data setting table including all items of revised items and non-revised items to transmit the generated taste data setting table together with update information indicative of the table information to be updated to the vehicle-mounted device, and further the server operates to generate update information indicative of the information on an old version of the taste data setting table to be updated for items corresponding to the latest version in the received information on the old version of taste data setting table to transmit the generated update information to the vehicle-mounted device, and
• wherein the server operates to respond to the reception of the user taste information corresponding to the latest version of the taste data setting table from the vehicle-mounted device to edit contents information on the basis of the user taste information to transmit the edited contents information to the vehicle-mounted device.
