Abstract

A portable audio enhancement and media player device and method are disclosed for enabling an electronic consumer product such as a personal computer, personal digital assistant (PDA), cellular phone or the like, to process and format media having different data formats such “wav” “mp3”, “mov”, “midi” files, and the like. The portable device may be connected to an electronic consumer product via a connector such as universal serial bus (USB), firewire, audio out, audio in, and the like. By connecting the portable device via one of the connectors, the portable device provides the required processors for processing audio/video media data necessary to play such data formats and enable the electronic consumer product with sound card and media player functionality. The portable device with media player functionality enables an electronic product such as a personal computer to obtain an additional secondary functionality such as audio enhancement when connected to the host computer and also aid in processing data when connected to the host computer.

Claims

1. A portable media processing device for connecting with and enabling an external device with audio enhancement functionality, the portable device comprising:

a housing and a connector interface for connecting and exchanging data with the external device;

a media player module for processing data; and

a controller for identifying the data received from the external device and selectively controlling the media player module for processing the data from the external device and supplying the processed data.

2. The portable media processing device of claim 1, further comprising a user interface port for connecting user interface devices.

3. The portable media processing device of claim 2, wherein the user interface devices are selected from the group consisting of:

speakers, earphones, headphones, displays, and monitors.

4. The portable media processing device of claim 1, wherein the media player module includes an audio data processor, and a media data processor.

5. The portable media processing device of claim 1, further comprising data storage for storing the processed data.

6. The portable media processing device of claim 2, wherein the controller supplies the processed data to either the external device or the user interface port.

7. The portable media processing device of claim 6, wherein the connector interface is either a USB connector interface or a firewire connector interface.

8. The portable media processing device of claim 7, wherein the external device is a device selected from the group consisting of:

a notebook, a personal computer, a television, a mobile telephone, a games console, a camera, a CD player, and a DVD player.

9. The portable media processing device of claim 1, wherein a portion of memory allocated for the processing of audio signals in the external device is freed up for use by a processor in the external device and processing of non-audio related tasks in the external device is enhanced.

10. A method for enabling an external device with audio enhancement functionality with a portable media processing device, the method comprising:

connecting the portable device to the external device;

receiving data from the external device;

identifying the data received from the external device;

selectively controlling a media player module, the media player module configured for processing the data; and

supplying the processed data to either the external device or a user interface port.

11. A media player device for processing media content, comprising:

a controller configured to select between a first mode and a second mode, wherein the first mode is selected if audio data is absent in the media content and the second mode is selected if audio data is present in the media content, the first mode being operable to process the media content without audio enhancement processing and the second mode being operable to apply audio enhancement processing to the audio data; and

a media player module configured to process media content according to the first mode and the second mode,

wherein if the first mode is selected, the processed media content is suitable for playback on an output display, and

wherein if the second mode is selected, the processed media content is suitable for playback on an audio output device.

12. The media player device of claim 11, wherein if the second mode is selected, the processed media content is suitable for playback on the audio output device without further audio processing, which is selected from the group consisting of digital-analog conversion, amplification, and filtering.

13. The media player device of claim 11, wherein if the second mode is selected, the processed media content is suitable for playback on the audio output device without further audio processing except amplification.

14. The media player device of claim 11, wherein the media player module comprises:

a media data processor configured to process the media content for playback without audio enhancement processing.

15. The media player device of claim 11, wherein the media player module comprises:

an audio data processor configured to apply audio enhancement processing to the audio content.

16. The media player device of claim 15, further comprising:

a connection interface configured to connect to an external device, receive the media content from the external device, and transmit to the external device the processed media content if the second mode is selected, wherein the audio output device is selected from the group consisting of a speaker, an earphone, and a headphone.

17. The media player device of claim 16, wherein the connection interface is configured to allow digital and analog communication with the external device over a general purpose interconnect, the general purpose interconnect being selected from the group consisting of a USB and a firewire.

18. The media player device of claim 16, further comprising:

an user interface connection configured to receive the processed media content in either the first or second modes and connect to the audio output device and the output display for outputting the processed media content.

19. The media player device of claim 11, wherein the audio enhancement processing is selected from the group consisting of virtualization technologies and transient enhancements.

20. The media player device of claim 11, wherein the media content is selected from the group consisting of audio data and non-audio data.
