Abstract

Die vorliegende Erfindung betrifft ein Verfahren zum Betreiben eines drahtlosen Audiosystems, welches mindestes ein zentrales Steuersystem (1) und ein Audioübertragungssystem bestehend aus Sendern und Empfangseinheiten umfaßt, und bei welchem eine Übertragung von Steuer- und/oder Audioinformationssignalen über eine Vielzahl von individuellen Übertragungskanälen erfolgen kann. Dabei findet ein Überprüfen der Übertragungsqualität einzelner Übertragungskanäle auf der einer jeden Empfangseinheit zugeordneten Funkstrecke zu Beginn der Übertragung durch sukzessive Durchführung von Messungen von frequenzspezifischen Empfangsfeldstärken bei im Verhältnis zur Bandbreite eines einzelnen Übertragungskanals relativ kleinen Frequenzschritten statt, wobei für einen jeden einzelnen Frequenzschritt die Empfangsfeldstärke über die Steuerfunkstrecke an die Zentraleinheit übermittelt wird. Sodann wird ein Kanalabbild in der Zentraleinheit festgelegt, welches die Bandbelegungssituation für jede einzelne Audioempfangsstation wiedergibt. Für jede Empfangseinheit findet sodann ein Ermitteln der Frequenzen statt, bei denen die Empfangsfeldstärke am wenigsten gestört ist, und die jeweils ausgewählt und zugewiesen werden.

Figure 00000001
The present invention relates to a method for operating a wireless audio system, which comprises at least one central control system (1) and an audio transmission system consisting of transmitters and receiving units, and in which transmission of control and / or audio information signals can take place via a plurality of individual transmission channels , In this case, the transmission quality of individual transmission channels is checked on the radio link assigned to each receiving unit at the beginning of the transmission by successively carrying out measurements of frequency-specific reception field strengths at relatively small frequency steps in relation to the bandwidth of a single transmission channel, the reception field strength being exceeded for each individual frequency step Control radio link is transmitted to the central unit. Then, a channel image is set in the central unit, which reproduces the band allocation situation for each individual audio receiving station. For each receiving unit then takes place a determination of the frequencies at which the reception field strength is the least disturbed, and which are respectively selected and assigned.
