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.
Claims11
A system comprising:
- a media playback device;
- and
- a converter device communicably coupled to the media playback device, 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 the media playback system;
- and
- firmware to control the transfer 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 via the port 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 converter device for receiving and converting a digital media stream from a server, the converter device comprising:
- a port to communicate with the server via a local area network;
- a user interface control device;
- a volatile memory buffer;
- a microprocessor in communication with the volatile memory buffer to convert the digital media stream into a format usable for playback of the digital media stream;
- and
- one or more non-volatile flash memories to store converter control firmware operable to cause the port to start receiving the digital media stream from the server in response to activation of the user interface control device and to control the transfer of the digital media stream from the server to insure that the volatile memory buffer is filled as the portions of the digital media stream already received via the port from the server and stored in the volatile memory buffer are being converted by the microprocessor into the format usable for playback of the digital media stream.
