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.
