Abstract

An audio converter device and a method for using the same. 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 system comprising:

a storage gateway device having an associated content management system configured to communicate a play list for accessing one or more of a plurality of digital media files to a client converter device in communication via a local area network with the storage gateway device, the client converter device adapted to display a representation of the play list received from the storage gateway device, wherein the client converter device is connected to the storage gateway device only by the local area network;

wherein commands for initiating playback via the client converter device of one or more digital media files represented on the displayed representation of the play list come from a remote control device;

wherein the client converter device further comprises;

a volatile memory buffer to store portions of a digital media file requested to be played when transmitted to the client converter device from the storage gateway device via the local area network; and

a non-volatile memory partitioned into at least two sectors, wherein the client converter device includes a control bit that indicates which sector of the at least two sectors from which an operating system and control firmware is loaded;

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

a buffer management function to control flow of the portions of the digital media file requested to be played from the storage gateway device to the client converter device to permit filling of the volatile memory buffer as portions of the digital media file already received from the storage gateway device and stored in the volatile memory buffer are being converted by the microprocessor.

2. The system as recited in claim 1, wherein a request to initiate playing of one or more digital media files represented on the displayed representation of the play list comprises a mark-up language formatted message.

3. The system as recited in claim 2, wherein the request comprises an HTTP request message.

4. The system as recited in claim 1, wherein the remote control device is configured to transmit commands to the client converter device using an IR protocol.

5. The system as recited in claim 1, wherein the remote control device is configured to transmit commands to the client converter device using a RF protocol.

6. The system as recited in claim 1, wherein the remote control device comprises a personal digital assistant.

7. The system as recited in claim 1, wherein the play list comprises digital media files stored in a memory associated with the storage gateway device.

8. The system as recited in claim 1, wherein the play list comprises digital media files stored on a web-based server accessible to the storage gateway device via a wide area network.

9. The system as recited in claim 1, wherein the remote control device is configured to transmit commands to the client converter device to cause the client converter device to transmit via the local area network to the storage gateway device a request to initiate playback via the client converter device of one or more digital media files represented on the displayed representation of the play list.

10. The system as recited in claim 1, further comprising a static buffer having one or more stored digital media files previously received from the associated content management system.

11. The system as recited in claim 10, wherein before the plurality of digital media files are accessed from the associated content management system, the static buffer is searched to locate one or more files from the playlist.

12. The system as recited in claim 1, further comprising a database having stored digital media files, wherein before the plurality of digital media files are accessed from the associated content management system, the database is searched to locate one or more files from the playlist.

13. The system of claim 1, wherein the client converter device is further configured to:

receive new versions of the operating system and the control firmware via a wireless local area network communication link;

load the new versions of the operating system and the control firmware to a sector of the non-volatile memory not indicated by the control bit; and

after verification of the new versions of the operating system and the control firmware, change the control bit to indicate that the client converter device is to load the operating system and control firmware from the sector of the non-volatile memory associated with the new versions of the operating system and the control firmware.

14. A storage gateway device comprising:

a content management system containing information regarding a plurality of digital media files from which a play list can be created;

an interface configured to communicate only via a local area network with a client converter device, wherein the client converter device is adapted to display a representation of the play list;

wherein the client converter device includes a non-volatile memory partitioned into at least two sectors, wherein the client converter device includes a control bit that indicates which sector of the at least two sectors from which an operating system and control firmware is loaded;

and

wherein the interface is further configured to communicate portions of selected digital media files from the storage gateway device to the client converter device, wherein flow of the portions of the selected digital media files communicated to the client converter device is controlled by a buffer management controller, wherein the buffer management controller is configured to control flow of the portions of the selected digital media files to permit filling of a volatile memory buffer at the client converter device as the portions of the selected digital media files already received from the storage gateway device and stored in the volatile memory buffer are being converted by a microprocessor.

15. The device as recited in claim 14, wherein the portions of selected digital media files are communicated in response to a request comprising a mark-up language formatted message.

16. The device as recited in claim 15, wherein the request comprises an HTTP request message.

17. The device as recited in claim 15, wherein the portions of the selected digital media files communicated to the client converter device are converted to a usable format at the client converter device.

18. A non-transitory computer-readable medium having instructions stored thereon that, upon execution by a computing device, cause the computing device to perform operations comprising:

creating a play list for accessing one or more of a plurality of digital media files;

communicating a representation of the play list;

receiving commands for initiating playback of one or more digital media files represented on a display of the representation of the play list, wherein the commands comprise a mark-up language formatted message; and

communicating portions of a digital media file requested to be played, wherein the portions of the digital media file are converted upon receipt into a usable format at a client converter device and flow of the portions of the digital media file requested to be played are controlled to permit filling of a store receiving the portions of the digital media file, wherein the computing device is connected to the client converter device only via a local area network, wherein the client converter device includes a non-volatile memory partitioned into at least two sectors, and wherein the client converter device includes a control bit that indicates which sector of the at least two sectors from which an operating system and control firmware is loaded.

19. The non-transitory computer-readable medium as recited in claim 18, wherein commands for initiating playback come from a remote control device, and wherein the remote control device transmits commands to the client converter device to cause the client converter device to transmit via a network a request to initiate playback via the client converter device of one or more digital media files represented on the display of the representation of the play list.

20. The non-transitory computer-readable medium as recited in claim 18, wherein the play list comprises digital media files stored on a server accessible via the local area network.
