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 identifying and searching for, any station in any band the receiver is capable of receiving.

Claims

1. 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 geographic region corresponding to a location of said broadcast receiver system and a datum representing a desired attribute;

searching means responsive to the inputted geographic region and the inputted datum representing the 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 desired attribute for the broadcast frequency identified by said searching means; and

data receiving means for receiving updating data to update said database in said memory means.

2. A broadcast receiver system as recited in claim 1, wherein the updating data is stored in a memory means separate from said memory means containing said database.

3. A broadcast receiver system as recited in claim 1, wherein the updating data replaces outdated data in said memory means.

4. A broadcast receiver system as recited in claim 1, wherein the data identifying attributes of each frequency broadcast into each geographic region stored in the database includes a call sign, a network affiliation, a program format, a language, and a geographical region.

7. A television broadcast receiver system as recited in claim 3, wherein the updating data replaces outdated data in said memory means.

5. A television 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 geographic region corresponding to a location of said television broadcast receiver system and a datum representing a desired attribute

searching means responsive to the inputted geographic region and the inputted datum representing the desired attribute for searching said one or more band files for a frequency broadcast into the geographic region of said television broadcast receiver system having the desired attribute;

display means for displaying the frequency and the desired attribute for the broadcast frequency identified by said searching means; and

data receiving means for receiving updating data to update said database in said memory means.

6. A television broadcast receiver system as recited in claim 5, wherein the updating data is stored in memory means separate from said memory means containing said database.

8. A television broadcast receiver system as recited in claim 5, wherein the data identifying attributes of each frequency broadcast into each geographical region stored in the database includes a call sign, a network affiliation, a program format, a language, and a geographical region.

9. A television 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 string a database of information relating to frequencies broadcast, said information including data identifying a network affiliation of each frequency broadcast;

input means for inputting a datum representing a desired network affiliation;

searching means responsive to the inputted datum representing the desired network affiliation for searching the database for a broadcast frequency received by said television broadcast receiver system having the desired network affiliation;

display means for displaying the frequency and the network affiliation for the broadcast frequency identified by said searching means; and

data receiving means for receiving updating data to update said database in said memory means.

10. A television 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 relating to frequencies broadcast, said information including data identifying a call sign of each frequency broadcast;

input means for inputting a datum representing a desired call sign;

searching means responsive to the inputted datum representing the desired call sign for searching the database for a broadcast frequency received by said television broadcast receiver system having the desired call sign;

display means for displaying the frequency and the call sign for the broadcast frequency identified by said searching means; and

data receiving means for receiving updating data to update said database in said memory means.
