The invention relates to a microphone system () having a microphone module () and having a base station (), wherein the microphone system () is designed to wirelessly transfer audio information () and additional information () from the microphone module () to the base station (), wherein the microphone system (), in particular the microphone module () is designed to transfer the additional information () and the audio information () via a common channel and/or in a common data stream.

Microphone system

Microphone systems having wireless microphones are often used in events such as discussions, concerts, plays, etc. and normally have a plurality of wireless microphones which are worn by users, such as actors, musicians, singers, etc, and one or more receiving stations which receive the audio signals of the wireless microphones and forward said signals to mixing consoles, amplification systems, recording devices, etc. In addition to the basic functionality of transmitting audio signals, microphone systems have become known which implement additional functions. The invention relates to a microphone modulehaving a transmitting unitwherein the transmitting unitis designed for the wireless transmission of audio information to a base station, having a receiving unit, wherein the receiving unitis designed to receive wirelessly transmitted status information and/or messages from a transmitterand having an output devicefor the output of the status information and/or messages to a user of the microphone module

Microphone module and microphone system having the microphone module

Wireless microphones are used in a plurality of applications, such as concerts, discussions, theater performances, operas, etc. The wireless microphones are normally connected to a transmitter which transmits the audio signals captured by the microphone to a base station via a transmitting frequency. The invention relates to a microphone system () having a base station () and having a microphone module () wherein the base station () is designed to wirelessly receive audio information and/or test information transmitted from the microphone module () on an operating frequency, wherein the base station () has a receiving analysis module () and/or is coupled thereto, which is designed to analyze the reception quality of the audio information and/or the test information on a plurality of possible transmitting frequencies, wherein the receiving analysis module () is designed to select the operating frequency from the plurality of possible transmitting frequencies.

Microphone system and method for selecting an operating frequency for a or said microphone system and computer program

Wireless microphone systems are used, for example, in theater, stage performances, television, broadcast radio or in concerts to amplify voices or instruments for a large audience. Due to the plurality of actors or musicians, a corresponding number of audio channels is required to transmit the audio information. 20 to 50 audio channels can thus be required in a parallel mode even in common applications. The invention relates to a network system () for audio equipment () having a plurality of base stations () and having a plurality of microphone modules () wherein the microphone modules () are and/or can be allocated to the base stations () via configuration data and wherein each microphone module () of a microphone-module-base-station allocation is designed to transmit audio information on a transmitting frequency F, F, F, F, FX, FY to the allocated base station () of the same microphone-module-base-station allocation, wherein the base stations () are networked to one another such that the configuration data are interchangeable, having a control device (), wherein the control device () is designed in respect of programming technology and/or circuit technology to automatically adapt the configuration data of the base stations () and/or microphone modules () and/or microphone-module-base-station allocations. The control device () is designed to adapt the configuration data in consideration of measured and/or calculated interactions of the microphone-module-base-station allocations and/or in consideration of the intended use of the respective microphone module ().

Network system for audio equipment, method and computer program

In a method for error correction of packet data, in particular DAB (digital audio broadcasting) data packets, code words being used over multiple data packets, redundancy information for error correction is added while maintaining the original packet data structure, at the cost of a free data field or a useful data field. The cycle of the error protection is selected as a multiple of a minimum size for a packet length.
