Rio Rocks Over Lawo IP

The biggest stars in music played Rock in Rio, but the broadcast mix for pay TV was handled nine miles away using IP infrastructure based on technology from Lawo.

Rio de Janeiro, Brazil (December 12, 2019) — Rock in Rio 2019, a ten-day event at Barra Olympic Park in Rio de Janeiro, Brazil, featured Drake, Foo Fighters, Bon Jovi, Red Hot Chili Peppers, Iron Maiden, P!nk, Muse and many others, and was broadcast live by Globosat using IP infrastructure based on technology from Lawo.

With an audience of over 45 million viewers across Brazil, Globosat is the largest pay TV operator in Latin America and the market leader in Brazil. To produce the 2019 edition of Rock in Rio, GloboSat furnished a remote production set-up connecting Cidade do Rock (Rock City) — the TV compound — at the Barra Olympic Park with GloboSat’s production center about nine miles away via two 2x 80Gbit/s optical fiber paths.


The TV compound was designed as the central point to collect all signals coming from the various stages. The smaller stages, including the Sunset Stage, were equipped with Lawo V__remote4 units for video and audio to IP conversion and signal processing, relaying the feeds to the TV compound located closely to the Palco Mundo main stage.

The immersive Dolby Atmos audio mix was produced at Globosat’s HQ using a Lawo mc²96 production console. The console and its Nova73 HD audio router also handled all audio routing for the 4K and HD productions. The sound engineers worked with 256 audio channels (128 per stage), which were recorded and distributed to various locations.

“We recorded up to 256 audio channels. We received streams, we generated streams, routed them to various locations and converted RAVENNA streams to MADI and DANTE or vice versa. This is only possible with a router like the one in the mc²96,” said Gabriel Thomazini, operational audio coordinator at Globosat.

“We used Lawo to encapsulate the signals and transport them to the Globosat HQ, which allowed us to work from home, in our familiar infrastructure and to record everything,” commented Alexandre Torres, Globosat’s development manager.

He continued: “IP has become a necessity for us. We operate dozens of channels originating from different contribution locations. IP furthermore allows us to engage in remote production, to easily automate certain routines and to share our signals with external parties. Setup times shrink and a significantly larger number of channels can be transported over a single cable at a much higher quality than in the past.”
