Abstract
A cellular phone including a transceiver and a processing module. The transceiver receives, from a device separate from the cellular phone, a radio or intermediate frequency signal. The radio frequency signal has been tuned by the device to a selected frequency. The intermediate frequency signal is a downconverted version of the radio frequency signal. Each of the radio and intermediate frequency signals includes the content. The content has been frequency modulated and broadcast at the selected frequency prior to the transceiver receiving the radio or intermediate frequency signal. A processing module downconverts the radio or intermediate frequency signal to a baseband signal and converts the baseband signal to a digital signal. The processing module either forwards the digital signal for audio play out of the content at the cellular phone or forwards the digital signal to the transceiver for transmission of the digital signal back to the device.
