Abstract

The invention relates first to a method for controlling a transmission system consisting of at least one transmitter (S1,... Sn) and at least one receiving unit (1), a signal (SIN) that is transmitted through a service channel (120) being amplitude-, frequency-, and/or phase-modulated. According to the invention, configuration parameters are transmitted to the receiving unit (1) through a control channel (110,, 113). This transmission through the control channel (110,, 113) takes place independently of any transmission that may have taken place through the service channel (120). Based on the configuration parameters that are transmitted, adjustments relating especially to the demodulation of the signal (SIN) that is transmitted through the service channel are made in the receiving unit (1). The invention also relates to an application for the method, to a transmission system, to a receiving unit and to a hearing aid.

Claims (17)

1. Method to control a transmission system consisting of at least one transmitter (S1, ..., Sn) and at least one receiving unit (1), wherein a signal (S IN) transmitted through an information channel (120) is modulated in amplitude, frequency and/or phase, characterized in that - the configuration parameters are transmitted through a control channel (110, ..., 113) to the receiving unit (1), said transmission through the control channel (110, ..., 113) being carried out regardless of any transmission implemented through the information channel (120), and - adjustments based on the transmitted configuration parameters are implemented in the receiving unit (1) and in particular enabling demodulating the signal (S IN) transmitted through the information channel.
2. Method according to claim 1, characterized in that an identification code is transmitted through the control channel (110, ..., 113) and in that the identification code is checked in the receiving unit (1) and on account of such a check the adjustments are carried out in the receiving unit (1), in particular according to the corresponding configuration parameters.
3. Method according to one of the preceding claims, characterized in that the receiving unit (1) is programmed by a programming unit (105), the transmission of the programming data taking place through the control channel (111).
4. Method according to claim 3, characterized in that information is transmitted from the receiving unit (1) through the control channel (111) to the configuration unit (105).
5. Method according to one of claims 2 through 4, characterized in that one or more identification codes are addressed to several receiving units (1).
6. Method according to one of the preceding claims, characterized in that - the demodulation of the signal (S IN) based on the configuration parameters is carried out, in particular using the generated frequency, to produce at least one demodulated signal (S, S out1, S out2, S DIGITAL), and - the demodulated signal or signals (S, S out1, S out2, S DIGITAL) are fed to another processing unit, in particular a hearing device (100) or an electro-acoustic transducer.
7. Method according to one of the preceding claims, characterized in that a total transfer function resulting from the transmitter (S1, ..., Sn) and the receiving unit (1) is modified in the receiving unit (1) by transmitting transfer-function parameters of the transmitter (S1, ..., Sn), in particular amplification and frequency of transmission, through the control channel (110, ..., 113) to the receiving unit (1) and in that the transfer function of the receiving unit (1) is modified in relation to a desired total transfer function.
8. Method according to one of the preceding claims, characterized in that an antenna (A) receiving the modulated signal (S IN) is tuned to the particular transmission frequency.

13. Transmission system according to claim 1l or 12, characterized in that the receiving unit (1) is connected to a hearing device (100) or to an electro-acoustic transducer.
14. Receiving unit (1) receiving frequency and/or phase modulated signals (S IN) which are received at an antenna (A) connected through a filter/amplifier unit (2) and a consecutive mixer (3) to a demodulator (4) to generate the demodulated signals (S; S out1, S out2, S DIGITAL), the mixer (3) furthermore being loaded with the output signal from a synthesizer (6) which in turn is controlled by a control unit (7), characterized in that transceiving means (8, 16, 17) for configuration parameters are connected to the control unit (6).
15. Receiving unit (1) according to claim 14, characterized in that the transceiving means for configuration parameters consist of a transceiver (8), a transceiving coil (15) and a capacitor (16) to adjust the transceiving coil (15).
16. Receiving unit (1) according to claim 14 or 15, characterized in that the filter/amplifier unit (2), the mixer (3), the demodulator (4), the synthesizer (6) and the control unit (7) can be made into an integrated circuit on a CMOS chip.
17. A hearing device fitted with a receiving unit (1) according to one of the claims 14 to 16.
