Abstract

The present invention includes a receiving antenna receiving information while changing plural different wireless base stations; a seat information acquiring unit acquiring position information of a destination seat paired; a wireless base station selecting unit selecting a wireless base station to be connected on the basis of position information; and a directivity switching unit changing directivity of the receiving antenna on the basis of position information, which transmits at least one of video information and audio information from a wireless base station to a user seated on the seat.

Claims

1. An image display device including a receiving antenna receiving information while changing a plurality of different wireless base stations, and movable between seats, comprising:

a seat information acquiring unit acquiring position information of a destination seat paired;

a wireless base station selecting unit selecting the wireless base station to be connected based on the position information; and

a directivity switching unit changing directivity of the receiving antenna based on the position information.

2. A wireless communication system comprising:

an image display device having a receiving antenna receiving information while changing a plurality of different wireless base stations, and movable between seats, including;

a seat information acquiring unit acquiring position information of a destination seat paired;

a wireless base station selecting unit selecting the wireless base station to be connected based on the position information; and

a directivity switching unit changing directivity of the receiving antenna based on the position information; and

the seat including a path changing unit changing a reception path of audio information received from the wireless base station,

wherein the wireless communication system transmits at least one of video information and audio information from wireless base station to the image display device and the seat.

4. The wireless communication system of claim 2,

wherein the seat further includes an audio output unit,

wherein the wireless communication system includes a wired transmission line connecting between the image display device and the audio output unit of the seat paired, and

wherein the path changing unit changes a path so as to output the audio information to the audio output unit via the wired transmission line.

5. The wireless communication system of claim 2,

wherein the seat further includes an audio output unit and a receiving antenna receiving audio information, and

wherein the path changing unit changes a path so as to output the audio information to the audio output unit via the receiving antenna placed on the seat paired.

6. The wireless communication system of claim 2,

wherein the image display device further includes an audio information output unit, and

wherein the path changing unit changes a path so as to output the audio information to the audio information output unit placed on the image display device.
