One transmitter, many listeners: Bluetooth gets broadcast mode
Berlin (dpa/tmn) – Being able to transmit music or information to many listeners at the same time has many advantages. Just think of classic broadcasting. The Bluetooth Special Group (SIG), responsible for the development of the radio standard of the same name, has now specified its plans for spatially limited audio transmissions to theoretically any number of Bluetooth headphones or speakers.
The new feature, called Auracast, is expected to be written into the Bluetooth LE Audio specifications and will be released in the coming months.
Auracast means: share and listen
It is still difficult to estimate when the first smartphones, notebooks, televisions or systems with Auracast will come onto the market. They could then wirelessly share their audio with nearby Auracast-enabled headphones, speakers, or hearing aids.
In any case, the Bluetooh SIG sees potential for Auracast not only in the private sphere, but also in public space. The technology can make what was previously silent audible on headphones, for example: the sound from television sets and displays at train stations, squares, airports, in sports halls, restaurants or waiting rooms.
In addition, audio transmissions or announcements, which previously only ran via loudspeaker systems, can also be received directly with Auracast-enabled Bluetooth headphones or hearing aids. For example at conferences or in the cinema.
