Abstract

A system for providing character-based information for a moving object include a GPS receiver receiving position information of the moving object, a character radio pager for receiving control information and character information, a living information database for storing the character-based information received from the character radio pager, a moving picture database for storing the control signals and operator information, a position information database for storing the position information from the movement of the moving object and providing announcement for the present moving position of the moving object, a CPU for extracting useful information from the GPS receiver and the character radio pager or extracting an announcement stored in the position information database under the control of a scheduler, a sound card and a video card for outputting the information of the database, and an advertisement control server for transmitting control signals to the character radio pager.

Claims

1. A system for providing character-based information for a moving object, the system comprising:

first and second scheduler;

a first receiving means for receiving and demodulating present position information indicating a present position of the moving object;

a second receiving means for receiving and demodulating control information and character-based information from a character radio paging network providing the character-based information;

a first store means for storing the character-based information received from the second receiving means;

a second store means for storing picture information to be used as a background picture when the character-based information is outputted;

a third store means for storing control signals received from the second receiving means and operator information directly inputted by an operator;

a fourth store means for storing previously generated position information related to a travel of the moving object;

a fifth store means for storing an announcement for the present moving position of the moving object;

a sixth store means for storing picture information to be used as a background picture when the announcement is outputted;

a control means for extracting useful information from the first, second and third store means or extracting the announcement stored in the fifth and sixth store means under control of the first scheduler in case where the present position information received from the first receiving means is consistent with the previously generated position information stored in the fourth store means;

an output means for outputting the information stored in the first, second, third, fifth and sixth store means;

a third receiving means for receiving character-based information from an external provider;

a seventh store means for storing the character-based information received from the third receiving means and control information from an external operator; and

a transmitting means for extracting the character-based and control information stored in the seventh store means and outputting the character-based and control information stored in the seventh store means to the second receiving means in response to a the second scheduler.

2. A system in accordance with claim 1, wherein the first receiving means comprises a GPS receiver for receiving and demodulating the present position information received from a GPS satellite.

3. A system in accordance with claim 1, wherein the first receiving means comprises a pulse receiver for measuring distance, wherein the pulse receiver receives distance majoring pulses from a pulse generator and demodulates the present position information.

4. A system in accordance with claim 1, wherein the output means comprises:

a voice and picture information processing means for processing the voice and picture information in the first second, third, fifth and sixth store means;

a voice output means for outputting the voice information received from the voice and picture information processing means;

a display processing means for determining a display type of the picture information received from the voice and picture information processing means; and

a picture output means for outputting the picture information received from the display processing means.

5. A system in accordance with claim 4, wherein, the operator information that is stored in the third store means, and directly inputted by the operator comprises moving and still picture information.

6. A system in accordance with claim 5, wherein the moving object is one of public transports.

7. A system for providing character-based information for a moving object, the system comprising:

first and second schedulers;

a first receiving means for receiving and demodulating control information and character-based information from a character radio paging network providing the character-based information;

a first store means for storing the character-based information received from the first receiving means;

a second store means for storing picture information to be used as a background picture when the character-based information is outputted;

a third store means for storing control signals received from the first receiving means and operator information directly inputted by an operator;

a control means for extracting and outputting useful information from the first, second and third store means in response to the first scheduler;

an output means for outputting the information stored in the first, second and third store means;

a second receiving means for receiving character-based information from an external provider;

a fourth store means for storing the character-based information received from the second receiving means, the control information from the first receiving means and control information from an external operator; and

a transmitting means for extracting the character-based and control information stored in the fourth store means and outputting the character-based and control information stored in the fourth store means to the first receiving means in response to the second scheduler.

8. A system in accordance with claim 7, wherein the output means comprises:

a picture information processing means for processing the picture information in the first, second and third store means;

a display processing means for determining a display type of the picture information received from the picture information processing means; and

a picture output means for outputting the picture information received from the display processing means.

9. A system in accordance with claim 8, wherein the output means further comprises:

a voice information processing means for processing the picture information in the third store means; and

a voice information processing means for processing the voice information received from the voice information processing means.

10. A system in accordance with claim 7, wherein, the operator information that is stored in the third store means, and directly inputted by the operator comprises moving and still picture information.
