Method of identifying a wireless communication channel in a sound system

Abstract

A method of identifies an appropriate wireless communication channel in an audio receiving device, that comprises 1) a wireless receiver receiving an audio signal on a particular transmission channel selected among a predefined number of possible transmission channels, and 2) a microphone for picking up a sound in the environment of the audio receiving device. The method comprises a) selecting a channel as the receiving channel among a predefined number of possible transmission channels; b) analyzing the received signal received and the signal picked up by the microphone; c) determining whether a predefined criterion concerning the degree of similarity of the received signal and the signal picked up by the microphone is fulfilled; d) KEEPING the channel as the receiving channel, if the predefined criterion is fulfilled; and e) CHANGING the receiving channel to another channel if the predefined criterion is NOT fulfilled.

Description

[0001]This application is a Divisional of copending application Ser. No. 13 / 477,770, filed on May 22, 2012, which claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application No. 61 / 488,809, filed on May 23, 2011, and under 35 U.S.C. §119(a) to Application No. EP 11167073.3, filed in Europe on May 23, 2011, all of which are hereby expressly incorporated by reference into the present application.TECHNICAL FIELD[0002]The present application relates to a sound system, e.g. a sound amplification system comprising wireless communication between various parts of the system.

The application furthermore relates to a listening device and to a sound system comprising an audio receiving device.[0003]The application further relates to a data processing system compri...

AI Technical Summary

Benefits of technology

The patent text describes a method for selecting an appropriate communication channel for a listening system, which is a simple and fast process. This method can be used for both uni-directional (broadcasting) and bi-directional (control) communication links. The method can use existing components of a listening system, such as wireless receivers and microphones. The text also describes a sound system that includes a multitude of binaural listening devices, which can exchange signals and control signals with each other. The channel selection procedure can be performed in either one or both of the two listening devices, and can be based on a predefined list of possible transmission channels. This method has the advantage of speeding up the search for an appropriate channel. Overall, the patent text presents a technical solution for efficiently selecting an appropriate communication channel for a listening system.

Problems solved by technology

One disadvantage of the above approach is that, it may be time consuming to find the appropriate channel.
