Abstract

An embedded device configured to provide an audio status output is disclosed. The embedded device includes a processor, an input button in electronic communication with the processor and a speaker in electronic communication with the processor for outputting an audio output. Memory is used for storing data. An audio output generator is stored in the memory and operates to generate the audio status output. The audio generator receives a generate audio command initiated by a user through use of the input button. The generator then operates to convert the status data to audio output data through use of an audio generation table. The audio output data includes multiple distinct audio signals that are machine-decipherable and that correspond to individual data elements of the status data. The audio output data is provided to the speaker such that the audio output based on the audio output data is generated.

Claims

accessing status data stored in the memory;

converting the status data to audio output data through use of an audio generation table, the audio output data comprising a plurality of distinct audio signals that are machine-decipherable and that correspond to individual data elements of the status data; and

providing the audio output data to the speaker such that the audio output based on the audio output data is generated.

2. The embedded device as defined in claim 1, wherein the embedded device is a microcontroller-based device.

3. The embedded device as defined in claim 1, wherein the audio output comprises DTMF tones.

4. The embedded device as defined in claim 1, wherein the status data includes dynamic device-specific input/output data.

5. The embedded device as defined in claim 1, wherein the status data includes state data.

6. The embedded device as defined in claim 1, wherein the status data is comprised of individual data elements, and wherein the audio generation table includes an audio translation for each of the individual data elements.

7. The embedded device as defined in claim 1, wherein the embedded device is a television.

8. The embedded device as defined in claim 1, wherein the embedded device is a consumer electronics device.

9. A system for providing an audio status output describing an embedded device to an audio status collector over a communication network, the system comprising:

an embedded device configured to generate the audio status output comprising;

a processor;

an input button in electronic communication with the processor;

a speaker in electronic communication with the processor for outputting an audio output;
