Abstract
The present invention provides a system for a moving body which enables a user to know a receivable broadcast station at the current position in real time and to select smoothly a desired broadcast station in a receiver even in an unfamiliar area. This system includes a broadcast station data memory that stores the channel data of a receivable broadcast station for each area, and a main processing circuit which is responsive to the vehicle's current position sensed by a coordinate computing unit for referring to the channel data and for showing the channel data of a receivable broadcast station at the current position on a display.
Claims32
A broadcast station data detector for a moving body, comprising:
- position sensing means for sensing a geographic position of the moving body;
- a broadcast station data memory which stores channel map data of a receivable broadcast station for a broadcast area;
- broadcast station data searching means for searching the channel map data in said broadcast station data memory based on the sensed geographic position of the moving body and outputting a receivable broadcast station prior to receiving any broadcast signal;
- and
- transmitting means for transmitting received broadcast signals to a radio set mounted on the moving body.
