Demonstration on Next-Generation Immersive Audio in a Live Broadcast Workflow

Rock in Rio is a music festival with appoximately 100,000 spectators at the festival site and millions either watching on TV, live streaming, or using other media to view it. To provide a sense of “being there,” we employed remote mixing using audio over IP to send audio from all of the microphones to our facility at Globosat, which was seven miles away from the festival site. The production workflow was designed to highlight next-generation concepts such as mixing in immersive audio and multidelivering the festival content to different media formats, for instance, Over-the-Air ISDB-Tb and 5G FeMBMS in Dolby Atmos & MPEG-H. And at the festival site, virtual reality (VR) experiences in MPEG-H and a VIP area with Dolby Atmos mixing.
