Abstract

Radio systems for supplying hearing apparatus in events rooms are of a more convenient design. To this end a radio transmission apparatus is provided for transmission of speech signals in an events room. It possesses a receive device for receiving at least one control signal and a switching device for switching the radio transmission apparatus on and/or off depending on the received control signal. In addition a control apparatus is provided for controlling the radio transmission device, with which speech signals are transmitted in an events room. This control apparatus possesses a detection device to detect a presence or a movement of the radio transmission device in the events room and a transmit device for transmitting a control signal to the radio transmission device depending on the detection result of the detection device. This allows a transmit device of a teacher to be switched off when they leave the classroom.

Claims

1-18. -18. (canceled)

19. A radio transmission apparatus, comprising:

a transmitting device that transmits a speech signal;

a receiving device that receives a control signal; and

a switching device that switches the transmitting device on and off depending on whether the receiving device receives the control signal.

20. The radio transmission apparatus as claimed in claim 19, wherein the control signal is received via radio or inductively.

21. The radio transmission apparatus as claimed in claim 19, further comprising a configuration device that automatically configures the radio transmission apparatus depending on the control signal.

22. The radio transmission apparatus as claimed in claim 21, wherein the radio transmission apparatus is automatically switched into a radio channel based on the control signal.

23. The radio transmission apparatus as claimed in claim 19, further comprising a mixing device so that a plurality of speech signals from a plurality of sound sources are mixed and transmitted.

24. The radio transmission apparatus as claimed in claim 19, wherein the control signal comprises a sequence of signals.

25. The radio transmission apparatus as claimed in claim 19, wherein the transmitting device is switched on if the receiving device receives the control signal or off if the receiving device does not receive the control signal.

26. The radio transmission apparatus as claimed in claim 19,

wherein the transmitting device transmits the speech signal in an event room, and

wherein the receiving device receives the control signal in the event room or at an entrance of the event room.

27. A control apparatus for controlling a radio transmission device to transmit a speech signal in an event room, comprising:

a detecting device that detects a movement of the radio transmission device in the event room; and

a transmitting device that transmits a control signal to the radio transmission device depending on the detection.

28. The control apparatus as claimed in claim 27, wherein the detecting device comprises two detection units that are built into a door frame of the event room or in front of or behind the door frame in order to detect a direction of the movement of the radio transmission device.

29. The control apparatus as claimed in claim 28,

wherein the detection unit comprises a localization unit that locates the radio transmission device in the events room, and

wherein the localization unit comprises a plurality of separate directional antennas.

30. The control apparatus as claimed in claim 28, wherein the control signal switches the radio transmission device on if the radio transmission device moves into the event room or off if the radio transmission device leaves out of the event room.

31. The control apparatus as claimed in claim 27, wherein the detecting device detects movements of a plurality of radio transmission devices in the event room.

32. A method for controlling a radio transmission device to transmit a speech signal in an event room, comprising:

detecting a presence of the radio transmission device in the event room;

transmitting a control signal based on the detection; and

operating the radio transmission device depending on the control signal.

33. The method as claimed in claim 32, wherein the radio transmission device is configured automatically based on the control signal.

34. The method as claimed in claim 33, wherein the radio transmission device is switched automatically into a radio channel based on the control signal.

35. The method as claimed in claim 32, wherein a plurality of speech signals from a plurality of sound sources are mixed and transmitted by the radio transmission device.

36. The method as claimed in claim 32, wherein the control signal switches the radio transmission device on if the presence of the transmission device is detected in the event room or off if the radio transmission device leaves out of the even room.

37. The method as claimed in claim 32, wherein the radio transmission device is switched on if the radio transmission device receives the control signal or off if the radio transmission device does not receive the control signal.

38. The method as claimed in claim 37, wherein the radio transmission device receives the control signal in the event room or at an entrance of the event room.
