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.

Abstract
A broadcast transmitting and receiving system includes a receiver having multiple tuners. A data tuner receives a data stream indicating the type of programming being broadcast by one or more stations. Based on information in the data stream, the frequency of operation of a sound tuner is adjusted to provide the user with a desired type of programming. Various modes of operation are provided, some employing a user interface and others being operable without user intervention.
