Abstract

We have disclosed an enhanced radio system that provides for the capture and playback of one or more radio stations. The user may tune to a station, or scan through stations, rewind to hear what was missed, and fast-forward through undesired content. The system allows a user to rate content, and to be notified when that content is being played on any station. The system may make radio station recommendations. The system allows the user to respond easily to radio content, download audio content, and send radio content to another user. The system may provide other radio related and radio content related information. The system may provide a karaoke mode. The system may also allow the user to integrate a telephone with the radio. The system may report usage information to a collection facility.

(d) an audio output device for outputting the analog audio signal;

(e) a controller for controlling the storing of the digital radio data and the converting of the digital radio data to the analog audio signal; and

(f) a user input device for allowing a user to control the controller, in which the system is additionally configured to allow the radio input received by each of the plurality of radio receivers to be stored into the corresponding buffer at the same time as previously stored digital radio data is converted from the corresponding buffer in which it was stored to an analog audio signal and output by the audio output device, and to automatically switch from a current user-selected radio station for listening by the user to another radio station broadcasting content of interest, which further permits the user to rewind to listen to an earlier buffered radio program in the corresponding buffer of the other radio station.

3. The system of claim 2 also comprising a two-way communications device.

4. The method of providing previously recorded radio output while recording new radio content comprising:

(a) receiving simultaneous radio input data from a plurality of unrelated radio stations from at least one radio source;

(b) storing a portion of each of the received radio data in a digital format into a buffer corresponding to each receiving in a memory device for later output by selection of a user, wherein the portion stored in the corresponding buffer is sufficient to later output a complete content of the digital radio data over a past period during which each of the plurality of radio receivers received the content and wherein the received and stored content, for at least two radio stations, each comprises a stream of content carrying continuous radio content from each of the radio stations over a period of time including in the radio content multiple radio programs and the corresponding buffer that is implemented locally on a player device for transient use by a user;

(c) converting the stored digital radio data to an analog audio signal;

(d) outputting the analog audio signal in an audio format;

(e) allowing a user to control the storing and the converting;

(f) allowing each of the radio input received to be stored in the corresponding buffer at the same time as previously stored digital radio data in the corresponding buffer is converted from the corresponding buffer in which it was stored to an analog audio signal and output in the audio format; and
