  • Broadcast receiver capable of autonomous format-scanning, program identification and searching
    Patent number: 5732338
    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.A broadcasting/receiving system, including a factory or user installed database containing a skeleton of scheduling information, provides a generic format-scanning ability to the user without forcing him or her to subscribe to an updating service, and provides an automatic identification means to that user.

  • Broadcast receiver capable of selecting stations based upon geographical location and program format
    Patent number: 4969209
    Abstract: A broadcast receiver is capable of selecting a broadcast station based upon a user selected program format and the geographical location of the receiver. The receiver includes a memory storing a database of information relating to frequencies of broadcast stations broadcasting into particular geographical locations and the program format of each such broadcast frequency. After a user inputs the geographical location of the receiver and a desired program format, the database may be scanned to select a broadcast frequency corresponding to the input geographical location and program format for retrieval. This selected frequency is used to tune the receiver. The geographical location, identification information, and program format for the selected frequency are then visually displayed.
