Abstract

A receiver device has a receiver having one or more tuners for demodulating one or more AM (Amplitude Modulation) and/or FM (Frequency Modulation) radio frequency broadcast audio signals. One or more signal processing devices convert demodulated signals into respective data streams each having a respective streamed media audio format. Each data stream is transmitted to a respective destination address. A graphical user interface provides remote users with information on radio broadcasters that are available for listening. This allows a remote user to select a particular radio broadcaster for listening. The device can be connected to a network, and users, which may be in locations where AM/FM reception is weak, can nonetheless have access to radio broadcasts. In some implementations, the receiver device is implemented in a router, a PC (Personal Computer), a server, or in any suitable audio and/or video equipment.
