A new Bluetooth audio scan-to-listen experience

Summary

A SIG paper on using QR codes to join Auracast broadcasts in bars, museums, transport, theatres and for private listening.

Key findings

• States that in most cases one transmitter will cover a whole venue, citing a Lincoln Center demonstration in which one small transmitter covered all 1,085 seats of Alice Tully Hall.
• Venues that limit listening, such as cinemas, theatres and meetings, can encrypt the broadcast and put the code in a QR code shown on a screen or electronic shelf label that changes with each showing or meeting.
• A theatre ticket can carry both the ticket code and the broadcast data, and the same broadcast code can be displayed at each auditorium entrance.
• Says the ability to use a QR code with Auracast will make it easier for listeners to choose what they want to hear, and calls the applications it describes simple to deploy.

Limits

An overview written to promote the feature. The Lincoln Center demonstration is reported without method, measurements, receivers used or whether the hall was occupied.
