Abstract

An information providing method and apparatus for providing information to a moving body via an artificial satellite. Information for selecting a desired information and position information of the moving body is transmitted, from the moving body. Information is provided to the moving body from the artificial satellite depending upon the position information of the moving body and the desired information, on the basis of information from the moving body.

Claims

1. An information providing method for providing information to a moving body via an artificial satellite, comprising the steps of:

transmitting information from said moving body via said artificial satellite, said transmitted information including position information of said moving body and desired information for said moving body which is selectable from available information; and

providing the selected desired information to said moving body via said artificial satellite depending upon said position information of said moving body and said selected desired information, on the basis of the information transmitted from said moving body.

3. An information providing method according to claim 1, wherein the available information includes at least one of a plurality of audio programs and a plurality of video programs, and the desired information which is selectable from the available information includes at least one of a desired audio program and a desired video program.

4. An information providing method according to claim 3, wherein the desired video-program is a cinema.

2. A transmission and reception apparatus to be mounted on a moving body for transmitting and receiving information with respect to an artificial satellite, comprising:

a transmitter for transmitting information from said moving body via said artificial satellite, said transmitted information including position information of said moving body and desired information for said moving body which is selectable from available information; and

a receiver for receiving the selected desired information via said artificial satellite at said moving body depending upon said position information of said moving body and said desired information transmitted from said moving body.

5. A transmission and reception apparatus according to claim 2, wherein the available information includes at least one of a plurality of audio programs and a plurality of video programs, and the desired information which is selectable from the available information includes at least one of a desired audio program and a desired video program.

6. A transmission and reception apparatus according to claim 5, wherein the desired video program is a cinema.
