An interactive radio system is provided for use with broadcast radio stations wherein feedback is provided to subscribers of the system via the Internet. Interactive radio mobile units are mounted within vehicles or at other locations. Each mobile unit includes a receiver for receiving radio broadcasts, a GPS system for determining the location of the vehicle, and a wireless transmitter for transmitting interactive radio control signals to a network operation center. While listening to a radio broadcast, the subscriber selects program segments of interest by pressing an interactive radio control button on the mobile unit. The program segments are, for example, individual musical selections, advertisements or the like. In response, the mobile unit transmits the carrier frequency of the radio broadcast, the date and time, the geographical location of the vehicle, and a subscriber identification signal to the network operation center using the wireless transmitter. The network operations center determines the identity of the selected program segment based upon the information transmitted from the mobile unit. Then, the network operation center accesses databases providing information pertaining to the selected program segment and provides the information to the subscriber via the Internet, such that the information can later be retrieved by the subscriber using a home or office computer or the like. By providing feedback via the Internet, the subscriber need not make decisions immediately regarding purchase of goods or services while listening to a radio broadcast. Moreover, a vast amount of information may be provided to the subscriber facilitating the purchase of goods or services or the like.

The system also includes a receive interface that is connected to either a tone signal detector or a frequency shift keying modulator. The system achieves speech cancellation by forming a Wheatstone bridge with a mirror circuit possessing a scaled image of the loop and office equipment impedance. In one embodiment of the invention the Wheatstone bridge is formed using the combined impedance of the loop and office equipment as the impedance that is to be matched by a set of balanced networks included within the system. In accordance with this aspect of the invention the Wheatstone bridge uses a parallel circuit with common end nodes containing two known resistances of equal value that are singularly connected to the unknown impedance and the matched impedance, respectively. Voltage division occurs across each circuit. When the unknown impedance is perfectly matched the voltage and signal phase in each circuit is the same. In another embodiment of the invention the resistances are replaced by using an active component. Specifically, a transistor pair is configured as mirrored current sources. e in 48B/50B format. A 48-bit word is created from the block of six characters by encoding the characters contained in the block. The 48-bit word is scrambled and a 2-bit synchronization sequence is appended to the scrambled 48-bit word. The result is the 50-bit byte frame in 48B/50B format. An alternate embodiment of the present invention includes a method for decoding data from the 48B/50B format. ristic, in a selected time clock. 9.
