Abstract

A system, apparatus, method, and media directed to navigation in the field of digital radio systems are provided. For example, an apparatus, method, or medium can be implemented to provide a multi-tuner portable digital radio device that includes multiple modes and/or advances navigation tools.

Claims

1. A portable multi-tuner digital radio device that processes multiple radio signals simultaneously and receives associated data for audio items carried by the radio signals, comprising options implemented on the device that provide a user of the device with the opportunity to select to enter the device into different operation modes including:

off mode wherein one or more tuners each continues to receive radio programming and the device continues to compress and store the received audio in its memory when the device is turned off, wherein the memory comprises a buffer configured to include adequate memory to buffer a predetermined duration of digitized and compressed audio content received from each of a plurality of the multiple tuners for later playback;

radio paused mode wherein the device is in an on mode and radio output is paused,

saving mode wherein during radio play incoming audio data is stored at a more permanent memory location; and

overlay mode wherein during one or more of the modes, a user feature is initiated that requires a use of a display or buttons of the device or buttons without affecting a current mode, wherein storage of radio programming received by all tuners continues, and playback of radio or stored content continues as begun prior to initiating the overlay mode, wherein at least one of the user features permits the user to indicate a favorite status for a first audio item and, the device is configured to use the associated data comprising artist or title of the first audio item and find other previously received audio items in the buffer where the buffered audio item has matching content, whereby the device finds other similar audio items in the buffer for the user for playback on the device,

wherein the device includes a phone mode, wherein while the device is in the phone mode, playback of radio or stored content is paused while radio play incoming audio data continues to be stored and while the device is no longer in phone mode, the device resumes playback of radio or stored content.

2. The device of claim 1 wherein the overlay device is operable during all modes and permits the user to interact with the display or buttons of the device without interrupting or changing the current mode.

3. The device of claim 1 wherein the device is a car radio.

4. The device of claim 1 wherein the device is an aftermarket car radio.

5. The device of claim 1 wherein the device includes a normal play mode.

6. The device of claim 1 wherein the device includes a saved content playback mode wherein output audio is taken from a stored audio file rather than from the radio content buffer.

7. The device of claim 1 wherein the memory is configured to simultaneously store in the buffer at least an audio portion of every radio signal received for later output by selection of the user.

8. The device of claim 1 wherein the device is configured to create and playback a personalized radio station using audio items similar to marked favorites, wherein the audio items are obtained from one or more sources including the buffer.

9. A portable multi-tuner digital radio device that processes multiple radio signals simultaneously and receives associated data for audio items carried by the radio signals, comprising options implemented on the device that provide a user of the device with the opportunity to select to enter the device into different operation modes including:

an off mode wherein one or more tuners each continues to receive radio programming and the device continues to compress and store the received audio in its memory when the device is turned off, wherein the tuners include one or more tuners corresponding to pre-set radio stations as selected by a user and at least one tuner corresponding to a radio station other than the pre-set radio stations, wherein the device allows the radio station other than the pre-set stations to be received at the same time as all of the pre-set stations, wherein the memory comprises a buffer configured to include adequate memory to buffer a predetermined duration of digitized and compressed audio content received from each of a plurality of the multiple tuners for later playback;

a radio paused mode wherein the device is in an on mode and radio output is paused;

a saving mode wherein during radio play incoming audio data is stored at a more permanent memory location; and

an overlay mode wherein during one or more of the modes, a user feature is initiated that requires a use of a display or buttons of the device or buttons without affecting a current mode, wherein storage of radio programming received by all tuners continues and playback of radio or stored content continues as begun prior to the overlay, wherein at least one of the user features permits the user to indicate a favorite status for a first audio item and the device is configured to use the associated data comprises artist or title of the first audio item and find other previously received audio items in the buffer where the previously received audio item has matching content that is received by the device, whereby the device finds other similar audio items in the buffer for the user for playback on the device,

wherein the device includes a phone mode, wherein while the device is in the phone mode, playback of radio or stored content is paused while radio play incoming audio data continues to be stored and while the device is no longer in phone mode, the device resumes playback of radio or stored content.

10. The device of claim 9 further including at least one spare tuner corresponding to a recently tuned station wherein the device allows the one spare tuner to keep track of the most recently tuned station in order to allow continuous reception thereof.

11. The device of claim 10 wherein the memory is configured to buffer and simultaneously store in a buffer at least an audio portion of every radio signal received for later output by selection of the user.

12. The device of claim 9 wherein the device is configured to create and playback a personalized radio station using audio items similar to marked favorites, wherein the audio items are obtained from one or more sources including the buffer.
