An information distribution device capable of distributing call attention information for calling attention to an event after confirming whether or not an event has occurred depending on circumstances is provided. A communication unit receives vehicle information, which relates to the behavior of a vehicle, and image information, which includes an image photographed by a vehicle has photographed, and distributes the call attention information for calling attention to an event, to a vehicle. A control unit determines whether or not to make a request to a vehicle for transmission of the image information, based on vehicle information or weather information, and makes a request to a vehicle for transmission of an image if it is determined to make a request for transmission of the image information.

Information distribution device

A database construction system constructs a database storing broadcast channels which are receivable in each area. A receiving unit receives probe information from a plurality of broadcast receiving apparatuses, the probe information including reception intensity of each of the broadcast channels and positions of the broadcast receiving apparatuses. An information storage unit stores the probe information received by the receiving unit. An extracting unit extracts the probe information with the same broadcast channel as that of new probe information, which is the probe information newly received by the receiving unit, among the probe information transmitted from a transmission area of the new probe information, from the information storage unit. A determining unit determines whether the new probe information is valid on the basis of the reception intensity included in the probe information extracted by the extracting unit and the reception intensity included in the new probe information. A database update unit updates the database using the new probe information that is determined to be valid by the determining unit.

Database construction system and broadcast receiving system

An information providing system is provided. An in-vehicle apparatus is provided in a vehicle. The in-vehicle apparatus receives a broadcasting. An information providing apparatus transmits area information related to a broadcast channel that is receivable in a traveling area of the vehicle to the in-vehicle apparatus. A storage unit stores the area information for each traveling area. A receiving unit receives probe information including a predetermined reference position or a position of the vehicle from the in-vehicle apparatus. A deciding unit decides a reference area set including a plurality of traveling areas which are within a predetermined distance from the reference position included in the received probe information for each vehicle. An accumulating unit accumulates the received probe information. A determining unit determines a traveling record of the vehicle in each traveling area on the basis of the accumulated probe information. An update unit updates the reference area set on the basis of the traveling record. A transmitting unit transmits the area information corresponding to the reference area set before the update to the in-vehicle apparatus corresponding to the reference area set when the update unit has not yet performed the update, and transmits the area information corresponding to the reference area set after the update to the in-vehicle apparatus corresponding to the reference area set when the update unit has performed the update.
