Abstract

A system for the control of mobile transmitting and/or receiving devices connected to a central unit, wherein the transmitting and/or receiving devices are adapted to transmit and/or receive data and/or signals in a first frequency range. In order in such a system to easily permit central control of mobile transmitting and/or receiving devices which are in a limited environment from the central unit, it is provided in accordance with the invention that the transmitting and/or receiving devices and the central unit have means for bidirectional communication in a second frequency range for control of the transmitting and/or receiving devices. The invention which can preferably be used in a limited environment such as a stage, a film studio, a music studio or a theater for the control of mobile apparatuses such as microphones, loudspeakers or cameras, also concerns a corresponding transmitting and/or receiving device, a corresponding central and sub-unit and a corresponding control method.

Claims

1. A system for controlling mobile transmitting and/or receiving devices wirelessly connected to a central unit, comprising that:

said transmitting and/or receiving devices are adapted to transmit and/or receive data and/or signals in a first frequency range; and

said transmitting and/or receiving devices and said central unit have means for bidirectional communication in a second frequency range for control of the transmitting and/or receiving devices.

2. The system as set forth in claim 1 wherein said first and second frequency ranges do not overlap.

3. The system as set forth in claim 1 wherein said transmitting and/or receiving devices and the central unit are adapted to transmit and/or receive audio and/or video data in the first frequency range.

4. The system as set forth in claim 3 wherein said transmitting and/or receiving devices are adapted to transmit and/or receive data in the form of mobile apparatuses, in particular a microphone, loudspeaker, audio and/or video monitoring device and/or a camera.

5. The system as set forth in claim 1 wherein said central unit is adapted for complete control and operation of transmitting and/or receiving devices.

6. The system as set forth in claim 1 wherein said central unit is adapted for setting the operating parameters of individual ones of or all transmitting and/or receiving devices.

8. The system as set forth in claim 1 wherein there is provided at least one mobile sub-unit wirelessly connected to the central unit for the control of individual transmitting and/or receiving devices.

9. The system as set forth in claim 1 wherein there is provided at least one autarkical sub-unit for the control of individual transmitting and receiving devices, which entirely or partially simulates the functionalities of the central unit.

10. The system as set forth in claim 1 wherein for an individual or each transmitting and/or receiving device in the second frequency range there is provided a separate frequency for bidirectional communication with the central unit.

11. The system as set forth in claim 1 wherein said central unit is adapted for programming of the transmitting and/or receiving devices with the required operating parameters immediately prior to use thereof.

12. The system as set forth in claim 1 wherein said transmitting and/or receiving devices are adapted for communication with each other.

13. The system as set forth in claim 1 wherein said central unit or an optionally provided sub-unit and the transmitting and/or receiving devices have a programming interface for loading new software into the transmitting and/or receiving devices by way of the bidirectional communication path in the second frequency range.

14. The system as set forth in claim 1 wherein said system is used for control of transmitting and/or receiving devices in a limited environment, in particular in a studio, a theater or a stage area.

15. The system as set forth in claim 14 wherein said limited environment has an entry lock for the transmitting and/or receiving devices for checking and/or setting the operating parameters of the transmitting and/or receiving devices when being brought into or taken out of the limited environment.

16. The system as set forth in claim 14 wherein said further elements in the limited environment, in particular lighting arrangements or stage elements, have means for bidirectional communication in the second frequency range for control by the central unit.

18. The transmitting and/or receiving device as set forth in claim 17 wherein said transmitting and/or receiving device is adapted for transmitting and/or receiving audio and/or video data and is in the form of a mobile apparatus, in particular a microphone, loudspeaker, monitoring device or camera.

19. A unit, in particular a central unit or a sub-unit, for a system as set forth claim 1, comprising means for wireless connection to transmitting and/or receiving devices for transmitting and/or receiving data and/or signals in a first frequency range, and further comprising means for bidirectional communication in a second frequency range for control of the transmitting and/or receiving devices.

20. The unit as set forth in claim 19 wherein said bidirectional communication means are arranged in a mobile unit, in particular a laptop, a PDA or a palmtop computer.

7. The system as set forth in claim I wherein said central unit is adapted to display the current setting of operating parameters of individual ones of or all transmitting and/or receiving devices.

17. A transmitting and/or receiving device for transmitting and/or receiving data and/or signals to a central unit by way of a radio path in a first frequency range, comprising means for bidirectional communication in a second frequency range for control of the transmitting and/or receiving devices by the central unit.

21. A method of controlling mobile transmitting and/or receiving devices wirelessly connected to a central unit, comprising:

arranging that said transmitting and/or receiving devices are adapted to transmit and/or receive data and/or signals in a first frequency range; and

effecting control of the transmitting and/or receiving devices by way of a bidirectional communication path in a second frequency range between transmitting and/or receiving devices and the central unit.
