How It Works
An unlimited number of in-range Auracast™ receivers will be able to join an Auracast™ broadcast from a nearby Auracast™ transmitter.
Step 1
An Auracast™ transmitter begins an Auracast™ broadcast that includes advertisements, which provide Auracast™ assistants with information about the broadcast (e.g. name, content, codec configuration, etc.), as well as one or more audio streams (e.g. left and right stereo audio streams).
Step 2
Auracast™ assistants scan for Auracast™ advertisements and provide a user interface (UI) to enable users to select an Auracast™ broadcast to join, similar to the UI commonly used to connect to Wi-Fi networks in public spaces.
Step 3
Once an Auracast™ broadcast is selected, the Auracast™ assistant provides the Auracast™ receiver (e.g. headphone, earbud, hearing aid, etc.) the information it needs to join the Auracast™ broadcast.
