A method for receiving audio data streams with mobile devices in different rooms in which sound is emitted via loudspeakers. Each mobile device connects over a local wireless network to a server that controls the sound emitted in the rooms via loudspeakers. Each mobile device detects room information, emitted only in the corresponding room, that indicates the room the respective mobile device is in. The room information is transmitted from each mobile device to the server. The server associates each room information with an output audio data stream that corresponds to the sound emitted via loudspeaker in the respective room in which the mobile device has detected the room information. The server assigns to each of the mobile devices an output audio data stream corresponding to the respective room information, and transmits the output audio data stream over the local network to the mobile device, which receives and replays it.

Method for receiving audio data streams with mobile devices and correspondingly configured mobile device

An improved method for configuring an audio reproduction device for detecting sound and providing different output audio signals in a plurality of rooms where at least two wireless microphones connect via a local network to an audio streaming server. Each of the wireless microphones detects room information indicating the room in which it is located, and transmits it to the server, together with an input audio signal. The server compiles at least two different output audio signals according to the respective room information from the input audio signals, and assigns each to a room. The output audio signals are provided via the local network in the rooms such that each of the output audio signals may be received in all rooms, and may be replayed only in the room to which it has been assigned. Each wireless microphone may be used in each of the rooms.

Audio reproduction system, method for configuring an audio reproduction system and server for an audio reproduction system

A method of low latency group-addressed audio/video streaming in an IEEE 802.11 wireless network is provided. A data stream from at least one access point is transmitted to a plurality of wireless receiving stations as multicast traffic. The data stream comprises beacon frames at beacon intervals. Data packets of the data stream from the at least one access point are transmitted to a plurality of wireless receiving stations as multicast traffic as soon as available for transmission. The transmission of data packets that were transmitted during a previous beacon interval is repeated during a subsequent beacon interval as multicast traffic.
