During its CES demo, Bluetooth SIG, the organization that defines Bluetooth standards, allowed show-goers to experience the aforementioned airport TV scenario. It was easy to switch between two sports broadcasts in a faux bar, simply by tapping one or the other in the Auracast menu. Another tap let us hear a private stream from a laptop, which was password protected so only the proper invitees can access it. There's also a use case where live audio from a lecture or performance can be broadcast via Auracast directly to earbuds, hearing aids or other Bluetooth listening devices. Impressively, there's no lag across any of the options as the visuals matched up perfectly each time.
