Claims
- 1. A system for transmitting and receiving program material and data corresponding to the program material, comprising:
- a transmitter subsystem, including
- (i) a transmitter unit;
- (ii) program sources providing to the transmitter unit the program material, for transmission thereof;
- (iii) a data stream generator providing to the transmitter unit the data corresponding to the program material, for transmission thereof;
- a receiver subsystem, including
- (i) a first tuner detecting the program material;
- (ii) a second tuner detecting the data stream; and
- (ii) a processor configured to change an operating frequency of one of said first tuner and said second tuner in response to the data stream.
- 2. A receiver for the reception of program material and associated data, comprising:
- a first tuner configured to detect the program material;
- a second tuner configured to detect the data stream;
- a user interface operatively coupled to one of the first tuner and second tuner providing user selection of an item from a menu of data options corresponding to one of the program material and associated data; and
- a processor configured to change an operating frequency of one of the first tuner and second tuner in response to the item.
- 3. A receiver for the reception of program material and associated data, comprising:
- a first tuner unit configured to detect the program material;
- a second tuner unit for detect the data stream;
- a user interface operatively coupled to the second tuner unit providing user selection of an item from a menu of data options corresponding to the received data; and
- a processor coupled to the user interface and the first tuner unit, the processor configured to change an operating frequency of the first tuner unit in response to user selection of the item.
- 4. A receiver for the reception of program material and associated data, comprising:
- a first tuner unit configured to detect the program material;
- a second tuner unit configured to detect a data stream corresponding to the associated data, the second tuner unit also configured to scan a predetermined band of frequencies for additional data streams;
- a user interface operatively coupled to the second tuner unit providing user selection of an item from a menu of data options corresponding to said data stream and said additional data streams; and
- a processor coupled to the user interface and the first tuner unit, the processor configured to change an operating frequency of the first tuner unit in response to user selection of the item.
- 5. A receiver for the reception of program material and associated data, comprising:
- a first tuner unit configured to detect the program material;
- a second tuner unit configured to detect a data stream corresponding to the associated data, the second tuner unit also configured to scan a predetermined band of frequencies for additional data streams; and
- a processor coupled to the first tuner unit and the second tuner unit, the processor configured to change an operating frequency of the first tuner unit in response to a characteristic of the associated data.
- 6. A receiver as in claim 5, wherein the characteristic includes correspondence of program-identifying data from a first station with program-identifying data from a second station.
- 7. A receiver as in claim 6, wherein the characteristic includes signal strength from the first station not exceeding a predetermined threshold and signal strength from the second station exceeding the predetermined threshold.
- 8. A receiver as in claim 5, further including a user interface operatively coupled to the processor, the user interface displaying available program type choices, an operating frequency of the first tuner being determined in response to user selection of one of the available program type choices.
- 9. A method of transmitting and receiving program material and data corresponding to the program material, comprising:
- transmitting said data, said data corresponding to program material being broadcast by a plurality of stations;
- receiving said data;
- processing said data; and
- selecting a frequency for reception of said program material in response to said processing.
- 10. A method as in claim 9, wherein said processing includes displaying information corresponding to program types on a user interface.
- 11. A method as in claim 9, wherein said processing includes determining which of a plurality of stations corresponding to a predetermined program type has a particular characteristic.
- 12. A method as in claim 11, wherein the particular characteristic is signal strength exceeding a threshold level.
