Provided is an on-vehicle device which can build a charge system which can charge in accordance with use of advertisement information. The on-vehicle device stores uplink information including some or all of information indicating whether the advertisement information is received, information indicating whether the received advertisement information is displayed, and information indicating whether a vehicle (C) has stopped before reaching an advertisement object point indicated by the advertisement information. Each of the information is made to be a charging object for advertisement.

On-vehicle device and advertisement information distribution system

A vehicle () starts from the front of a home () and moves to a destination (). An area (area) with the home () at the center is an area where the position of the home () is estimated to be easily specified, and a road () to be searched is a road required for searching a moving route of the vehicle (). An in-vehicle device () does not transmit position information or the like acquired in the area (area) in response to a request of position information from a road side device (). The in-vehicle device () transmits the position information or the like on the vehicle () acquired after the vehicle () moves out of the area (area) to the road side device (). The position information on the vehicle is transmitted to the road side device by protecting personal information.

Mobile body position information transmitting device for navigation system, and mobile body position information transmission method and program for navigation system

Provided is a navigation device which can automatically display on a map screen, an icon of a facility, information of which is not held in the navigation device. According to the navigation device (), when it is judged that content information received from a roadside radio device () contains 'object facility coordinate information' and 'icon image information', these information are written into a facility information table (). When displaying a map screen and an existing facility icon on a display unit (), it is judged whether the facility information table () contains facility icon information having coordinate information contained within a range indicated by the map screen. If YES, the corresponding facility icon is overlay-displayed on the map screen and the existing facility icon.

Navigation device and display method

A road-vehicle communication system warns or gives caution to a vehicle traveling in a reverse way direction and may also give warning to vehicles traveling in a correct direction. The road-vehicle communication system includes a first roadside apparatus at an entrance gate that gives entry gate pass information indicating that a vehicle passing a communicative area has entered a toll road. A second roadside apparatus at an exit ramp acquires any given entry gate pass information from a passing vehicle. An administration device judges whether or not the entry gate pass information is acquired from the passing vehicle. If the entry gate pass information is not acquired, the second roadside apparatus provides the vehicle with reverse-way driving warning information for warning the vehicle that the vehicle is traveling in the reverse direction.

Road-vehicle communication system

An on-vehicle device () includes a self-position detection unit (), a position match judgment unit (), an advance direction detection unit (), and a direction match judgment unit (). At the moment when a mobile body such as a vehicle having the on-vehicle device passes through an intended point of a data distribution side in an intended direction, a data reproduction unit () starts reproduction of content data associated with creation of the data distribution side acquired by a data acquisition unit (). When there a plurality of content data intended to be simultaneously reproduced by the data distribution side, it is judged by a parallel reproduction judgment unit (), and the data reproduction unit () reproduces the content data in parallel. The data is reproduced according to the intention of the data distribution side.

Information providing system, information providing method, and computer program

A changer type disc player capable of reproducing discs in a proper order depending upon the type of disc. The changer type disc player can load a plurality of discs and automatically interchange and reproduces discs, and includes a controller for reading disc management information of all discs after the discs are loaded and controlling to reproduce the plurality of discs in a predetermined order depending upon the types of discs.
