Abstract
A broadcasting system capable of automatically or semi-automatically updating its database and using the database to identify received broadcasting stations, and search for stations according to user-chosen attributes and current data. The receiver is capable of receiving current location information within the received data stream, and also of determining the current location of the receiver by using a received station attribute. The receiver is capable of identifying and searching for, any station in any band the receiver is capable of receiving.
Claims11
A broadcast receiver system comprising:
- a receiver for receiving a plurality of frequencies broadcast from a plurality of geographic regions;
- tuning means for tuning said receiver to one of the plurality of broadcast frequencies for reception thereof;
- memory means for storing a database of information in one or more band files relating to frequencies broadcast into each of the plurality of geographic regions, said information including data identifying attributes of each frequency broadcast into each geographic region;
- input means for inputting a datum representing a desired attribute;
- searching means responsive to the inputted datum representing a desired attribute for searching said one or more band files for a frequency broadcast into the geographic region of said broadcast receiver system having the desired attribute;
- display means for displaying the frequency and the attribute data for the broadcast frequency identified by said searching means;
- and
- data receiving means for receiving geographic location data defining a particular geographical region out of the plurality of geographical regions and/or updating data to update said database in said memory means.
