Abstract

A method for operating an audio system for transmitting wireless audio streams to a hearing system comprising a hearing device, the audio system comprising a communication unit and a radio system comprising a transmitter unit, the method includes: receiving request data comprising hearing device identification data and a request indicative of an audio track; determining radio system configuration data based on at least a part of the request data; and transmitting an audio stream by the transmitter unit according to the determined radio system configuration data, wherein the audio stream comprises audio stream data and audio identification data for allowing the hearing system to receive the audio stream representative of the requested audio track.

Claims

1. A method for operating an audio system for transmitting wireless audio streams to a hearing system comprising a hearing device, the audio system comprising a communication unit and a radio system comprising a transmitter unit, the method comprising:

receiving request data comprising hearing device identification data and a request indicative of an audio track;

determining radio system configuration data based on at least a part of the request data; and

transmitting an audio stream by the transmitter unit according to the determined radio system configuration data, wherein the audio stream comprises audio stream data and audio identification data for allowing the hearing system to receive the audio stream representative of the requested audio track.

2. The method according to claim 1, wherein the request data comprises an encryption key, the method further comprising encrypting the audio stream data with the encryption key before transmitting the audio stream.

3. The method according to claim 1, wherein the act of receiving the request data comprises receiving the request data from a hearing device of the hearing system.

4. The method according to claim 1, wherein the act of receiving the request data comprises receiving the request data from an accessory device of the hearing system, wherein the accessory device comprises a mobile phone, a tablet computer, a smart phone, a hearing device remote control unit, or a key card.

5. The method according to claim 1, wherein the act of receiving the request data comprises receiving the request data at a frequency anywhere from 2.4 GHz to 2.5 GHz, a frequency anywhere from 800 MHz to 1 GHz, and/or a frequency anywhere from 13 MHz to 14 MHz.

6. The method according to claim 1, wherein the act of receiving the request data comprises receiving the request data from a user interface unit of the audio system.

7. The method according to claim 1, wherein the audio identification data comprises one or more of a hearing device ID, a transmitter ID, a transmitter group ID, an audio group ID, an audio type ID, and an audio protocol ID.

8. The method according to claim 1, further comprising:

determining hearing system configuration data based on the request data; and

transmitting the hearing system configuration data to the hearing system for allowing the hearing system to receive the audio stream representative of the requested audio track.

9. An audio system for transmitting wireless audio streams to a hearing system comprising a hearing device, the audio system comprising:

a radio system comprising a stationary transmitter unit including a first transmitter unit for transmitting at least a first audio stream with first audio identification data indicative of the first audio stream;

a communication unit configured to communicate with the hearing system;

wherein the audio system is configured to

receive request data comprising hearing device identification data and a request indicative of an audio track,

determine radio system configuration data based on at least a part of the request data, and

transmit an audio stream according to the determined radio system configuration data, wherein the audio stream comprises audio stream data and audio identification data for allowing the hearing system to receive the audio stream representative of the requested audio track.

10. The audio system according to claim 9, wherein the communication unit comprises a wireless receiver for receiving the request data.

11. The audio system according to claim 9, wherein the communication unit comprises a near field communication device configured to receive hearing device identification data from a near field communication tag of the hearing system.

12. The audio system according to claim 9, wherein the communication unit is configured to receive the request data from an accessory device.

13. The audio system according to claim 9, wherein the radio system comprises a second transmitter unit for transmitting a second audio stream with second audio identification data indicative of the second audio stream, and a radio system control unit connected to the first and second transmitter units, wherein the radio system control unit is configured to control the first and second transmitter units.

14. The audio system according to claim 9, wherein the audio system comprises a user interface unit connected to the communication unit, wherein the user interface is configured to receive the request data indicative of the audio track, and to transmit the request data to the communication unit.

15. The audio system according to claim 9, wherein the request data comprises an encryption key, and the radio system is configured to encrypt the audio stream data with the encryption key before transmitting the audio stream.
