Abstract

An audio converter device and a method for using the same are provided. In one embodiment, the audio converter device receives the digital audio data from a first device via a local area network. The audio converter device decompresses the digital audio data and converts the digital audio data into analog electrical data. The audio converter device transfers the analog electrical data to an audio playback device.

Claims

1. A converter device to playback digital media, the converter device comprising:

a local area network port to receive portions of a digital media file stored on a local server;

a volatile memory buffer to store the portions of the digital media file;

a microprocessor to convert a portion of the digital media file stored in the volatile memory buffer into a format usable by a conventional media playback system;

a buffer management function to control flow of the portions of the digital media file from the local server for insuring that the volatile memory buffer is filled as the portions of the digital media file already received from the local server and stored in the volatile memory buffer are being converted by the microprocessor to thereby avoid interruption of media playback;

a user interface to allow a user to navigate through a hierarchical presentation of data associated with the digital media file; and

an infrared receiver to receive instructions from a remote controller for transfer of the converted portion of the digital media file to the conventional media playback device.

2. The converter device of claim 1, further comprising a user interface to allow users to manipulate the transfer of the converted portion of the digital media file.

3. The converter device of claim 1, further comprising a portable electronic device to allow users to manipulate the transfer of the converted portion of the digital media file.

4. The converter device of claim 3, wherein the portable electronic device is a personal digital assistant.

5. The converter device of claim 1, further comprising a display to present data associated with the digital media file received from the local server.

6. The converter device of claim 1, further comprising a local area network adaptor in communication with the local area network port.

7. A converter device to playback digital media, the converter device comprising:

a local area network port to receive portions of a digital media file stored on a local server;

a volatile memory buffer to store the portions of the digital media file;

a microprocessor to convert a portion of the digital media file stored in the volatile memory buffer into a format usable by a conventional media playback system; and

a buffer management function to control flow of the portions of the digital media file from the local server for insuring that the volatile memory buffer is filled as the portions of the digital media file already received from the local server and stored in the volatile memory buffer are being converted by the microprocessor to thereby avoid interruption of media playback.

8. The converter device of claim 7, further comprising a user interface to allow users to manipulate transfer of the converted portion of the digital media file to the conventional media playback system.

9. The converter device of claim 7, further comprising a portable electronic device to allow users to manipulate transfer of the converted portion of the digital media file to the conventional media playback system.

10. The converter device of claim 9, wherein the portable electronic device is a personal digital assistant.

11. The converter device of claim 7, further comprising a display to present data associated with the digital media file received from the local server.

12. The converter device of claim 7, further comprising a local area network adaptor in communication with the local area network port.
