Information providing system, information providing method, and computer program

An information providing system, comprising:

• at least one roadside device placed on the roadside for transmitting information signal via wireless communication;
• and
• at least one vehicle-mounted device for receiving the information signal transmitted from the at least one roadside device via the wireless communication, and reproducing the received information signal for output;
• wherein the at least one roadside device is placed at the roadside along the road through which a vehicle passes, in parking spaces, or in the proximity of the road and the parking spaces, each of the at least one roadside device comprising;
• a storage unit adapted to store content data to be transmitted and reproduction control data indicating a condition required for reproducing the content data;
• and
• a wireless communication unit adapted to transmit the content data and the reproduction control data stored in the storage unit;
• each of the at least one vehicle-mounted device comprising:
• a position identifying unit adapted to identify a position of a vehicle-mounted device;
• a receiving unit adapted to receive the content data and the reproduction control data transmitted from the roadside device;
• a match detecting unit adapted to determine whether the position of the vehicle-mounted device identified by the position identifying unit matches with the condition required for reproducing the content data which the reproduction control data indicates;
• and
• a data reproducing unit adapted to reproduce the content data if the match detecting unit determines that there is a match.

An information providing method, comprising the steps of:

• identifying a position of a vehicle-mounted device;
• receiving content data and reproduction control data indicating a position at which the content data is to be reproduced, the content data and the reproduction control data being transmitted from a roadside device to the vehicle-mounted device via wireless communication;
• detecting that the position of the vehicle-mounted device identified by the position identifying unit matches with the position at which the content data is to be reproduced which is indicated by the reproduction control data received at the receiving unit;
• and
• reproducing the content data if a match is detected.

An information providing method, comprising the steps of:

• wirelessly transmitting content data and reproduction control data indicating a condition required for reproducing the content data from a roadside device placed at the roadside along the road through which a vehicle passes, in parking spaces, or in the proximity of the road and the parking spaces;
• identifying a position of a moving vehicle;
• receiving the content data and the reproduction control data transmitted from the roadside device via wireless communication;
• determining whether the identified position of the moving vehicle matches with the condition required for reproducing the content data which the reproduction control data indicates;
• and
• reproducing the content data on the moving vehicle side if it is determined that there is a match.

An information providing system, comprising at least one roadside device placed at the roadside for wirelessly transmitting information signal, and at least one vehicle-mounted device for receiving and reproducing the information signal wirelessly transmitted from the roadside device:

• wherein the at least one roadside device is placed at the roadside along the road through which a vehicle passes, in parking spaces, or in the proximity of the road and the parking spaces, each of the at least one roadside device comprising:
• a storage unit adapted to store content data to be transmitted and reproduction control data indicating a condition required for reproduction;
• and
• a wireless communication unit adapted to transmit the content data and the reproduction control data stored in the storage unit;
• each of the at least one vehicle-mounted device comprising:
• a position acquiring unit adapted to acquire a position of a vehicle-mounted device;
• a receiving unit adapted to receive the content data and the reproduction control data from the roadside device;
• a determination unit adapted to determine whether the condition required for reproduction indicated by the reproduction control data received at the receiving unit is satisfied on the basis of the position of the vehicle-mounted device acquired by the position acquiring unit;
• and
• a data reproducing unit for reproducing the content data if the determination unit determines that the condition required for reproduction is satisfied.

An information providing apparatus, comprising:

• a position acquiring unit adapted to acquire a position of a vehicle-mounted device;
• a receiving unit adapted to receive content data and reproduction control data indicating a condition required for reproduction, the content data and the reproduction control data being received from a roadside device placed at the roadside for wirelessly transmitting the content data and the reproduction control data;
• a determination unit adapted to determine whether the condition required for reproduction indicated by the reproduction control data received at the receiving unit is satisfied on the basis of the position of the vehicle-mounted device acquired by the position acquiring unit;
• and
• a data reproducing unit adapted to reproduce the content data if the determination unit determines that the condition required for reproduction is satisfied.

An information providing method, comprising the steps of:

• acquiring a position of a vehicle-mounted device;
• receiving content data and reproduction control data indicating a condition required for reproduction, the content data and the reproduction control data being received from a roadside device placed at the roadside for wirelessly transmitting the content data and the reproduction control data;
• determining whether the condition required for reproduction indicated by the reproduction control data received at the receiving step is satisfied on the basis of the position of the vehicle-mounted device acquired by the acquiring step;
• and
• reproducing the content data if it is determined in the determining step that the condition required for reproduction is satisfied.

A computer readable program stored in the memory, the program being executed on a computer so as to allow the computer to operate as:

• a position acquiring unit adapted to acquire a position of a vehicle-mounted device;
• a receiving unit adapted to receive content data and reproduction control data indicating a condition required for reproduction, the content data and the reproduction control data being received from a roadside device placed at the roadside for wirelessly transmitting the content data and the reproduction control data;
• a determination unit adapted to determine whether the condition required for reproduction indicated by the reproduction control data received at the receiving unit is satisfied on the basis of the position of the vehicle-mounted device acquired by the position acquiring unit;
• and
• a data reproducing unit adapted to reproduce the content data if the determination unit determines that the condition required for reproducing the content data is satisfied.
