Abstract

A method for remote control of an audio device (1) is described, which receives an audio data stream (A) from a transmission system. A control command in the form of an audio data sample (AM) within the audio data stream (A) is sent to the audio device (1). The received audio data stream (A) is analyzed by means of an audio sample recognition system (2) in or on the audio device (1). A recognized audio data sample (AM) is converted into control data (SD, ST) and depending on the control data (SD, ST), certain components (7, 8) of the audio device (1) are activated in a certain manner.

Claims

1. A method for remote control of an audio device (1) which receives an audio data stream from a transmission system, in which

a control command within the audio data stream (A), is transmitted to the audio device (1) in the form of an audio data sample (AM)

and the received audio data stream (A) is analyzed in or on the audio device (1) by means of an audio sample recognition system (2)

and a recognized audio data sample (AM) is converted into control data (S_D, S_T)

and depending on the control data (S_D, S_T) certain components (7, 8) of the audio device (1) are controlled in a certain manner.

2. A method as claimed in claim 1, characterized in that the received audio data stream (A) is first pre-analyzed in respect of certain key audio data samples and on recognition of a certain key audio data sample, the subsequent audio data are analyzed for determining an audio data-sample (AM) assigned to the control data (S_D, S_T).

3. A method as claimed in claim 1, characterized in that the received audio data stream (A) is analyzed by means of a speech recognition system (2).

4. A method as claimed in claim 1, characterized in that in dependence on the control data (S_T) certain operating elements of a user interface (8) are assigned certain functions.

5. A method as claimed in claim 1, characterized in that an optical output device (7) of the audio device (1) is controlled in dependence on the control data (SO).

6. A method as claimed in claim 1, characterized in that in dependence on a received key audio data sample and/or received control data the audio data sample (AM) corresponding to the control data is filtered out before the audio data stream (A) is transmitted to a user.

7. A method as claimed in claim 1, characterized in that the control command (5) is first formed into a non-audio format representation and then converted to an audio data sample (AM) and integrated with an audio data stream (A) to be transmitted to an audio device (1).

8. A method as claimed in claim 1, characterized in that, the control command (S) present in the form of an audio data sample (AM) is checked by means of a simulator facility (14) comprising an audio sample recognition system corresponding to the audio device (1) before integration into the audio data stream (A) and/or before transmission to an audio device (1).

11. A simulator facility (14) for a control device (10) for control of an audio device (1) as claimed in claim 1, comprising an audio sample recognition system (2) corresponding to the audio device (1), to check the control command (S) present in the form of an audio data sample (AM).

9. An audio device (1) comprising

a receiving unit (6), to receive an audio data stream (A), and

an audio sample recognition system (2) for analysis of the received audio data stream (A), to recognize a control command in the form of audio data samples (AM) within the audio data stream (A), comprising an interpretation unit (4) for conversion of the recognized audio data sample (AM) into control data (S_p, S_r), to activate certain components (7, 8) of the audio device (1) in a certain manner depending on the control data (S_p, S_r).

10. A control device (17) for controlling an audio device (1) as claimed in claim 9, comprising an audio synthesizer (12) to convert a control command (5) from a non-audio format representation into an audio data sample (AM), and an integration device (15), to integrate the audio data sample (AM) into an audio data stream (A) to be transmitted to an audio device (1).
