Information providing system

Abstract

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.

Description

[0001] The entire contents of the claimed disclosure of Japanese Patent Application No. 2009-296429 filed on December 25, 2009, including specification, drawings and claims of the disclosure, are hereby incorporated by reference. Background technique [0002] The present invention relates to an information providing system, and more particularly, relates to a system capable of reducing the number of times a vehicle-mounted device receiving broadcasts receives information related to a broadcast channel that can be received from an information-providing device within a driving area of ​​a vehicle, and through the vehicle-mounted device from An information providing system of the amount of information received at the information providing device. [0003] An information providing system is proposed in which a predetermined server provides information on broadcast channels, which can be received at a location where a broadcast receiving device is placed. For example, JP-A-2005-252...

AI Technical Summary

Problems solved by technology

[0010] However, when the center transmits information about the whole of Japan to the vehicle-mounted device as information on broadcast channels receivable at each receiving location, a new problem arises that the amount of information received by the vehicle-mounted device from the center increases
