How Auracast™ Broadcast Audio Works
With Auracast™ broadcast audio, an unlimited number of in-range Auracast™ receivers will be able to join an Auracast™ broadcast from a nearby Auracast™ transmitter.
Connecting to an Auracast™ broadcast audio stream is not the same as a standard pairing between two Bluetooth® devices. With an Auracast™ broadcast audio stream, a transmitter advertises the availability and information details of the stream. Any Auracast™ receiver or assistant can listen for that broadcast and join based on the user’s request. At the heart of a broadcast, the transmitter does not know what types or how many devices are listening to the Auracast™ broadcast audio stream. This allows for one transmitter to broadcast to an unlimited number of receivers within range. Some broadcasts may be encrypted and require additional input by the user, depending on the implementation.
A smartphone is not required to listen to an Auracast™ broadcast audio stream. Once joined, the receiver listens to a direct audio stream from the transmitter. The smartphone is not involved in the listening process. That said, there are two common methods for finding and joining an Auracast™ broadcast audio stream – with and without an assistant.
