Brazil. Rock in Rio has ranked among the largest music festivals in the world and moved beyond its native Rio de Janeiro with events in Lisbon, Madrid and Las Vegas. It is also broadcast live by Globosat using IP infrastructure based on technology from the German pioneer of IP transmission, Lawo.
Rock in Rio 2019 was a ten-day event. To produce this edition, GloboSat provided a remote production setup connecting the TV compound, also known as a. "Cidade do Rock" (Rock City), in barra's Olympic Park with globoSat's production center approx. 15 km away via two 2x 80Gbit/s fiber optic paths.
The TV compound was designed as the central point to collect all the signals coming from the different stages. Smaller stages, including the Sunset Stage, were equipped with Lawo V__remote4 units for video and audio to IP conversion and signal processing, transmitting the feeds to the TV compound located near the main stage "Palco Mundo".
Given the relatively small distance, the 16 cameras and audio transmissions from the main stage were transmitted to the infrastructure of the TV complex via SDI. The TV complex's redundant IP infrastructure was built on top of Arista 7280 and Lawo V__matrix switches to convert baseband SDI signals to IP, process and compress video signals, and provide multiviewers.
One of the sheets V__matrix C100 was used to generate a mosaic of multiple viewers with 24 embedded images whose design was prepared with Lawo's theWall software. The other software-defined C100 blades were dedicated to processing and conversion tasks. In total, 28 HD 1080i feeds and VC2-compressed 4K feeds were used for video production. At GloboSat's headquarters, the facility's V__matrix infrastructure received HD and 4K transmissions plus discrete audios from the TV composite for remote production.
To monitor and ensure the signal integrity of all production ST2110 feeds, GloboSat used Lawo's SmartSCOPE deep packet media inspection and network analysis solution. By installing on a server at the main facility, it also allowed for easy on-site access and monitoring in the remote TV complex via the smartSCOPE web interface.
The immersive Dolby Atmos audio mix was produced at Globosat's headquarters using a Lawo mc²96 production console. The console and its Nova73 HD audio router also handled all audio routing for full 4K and HD productions. The sound engineers worked with 256 audio channels (128 per stage), which were recorded and distributed to various locations. The router within a Lawo mc²96 console allows you to handle up to 256 IP streams, making it ideal for routing in complex audio configurations across multiple sites.
The remote production of Rock in Rio was not the first of its kind for Globo. Being recognized for pioneering broadcasting in Brazil with the first live broadcast in 4k and Dolby Atmos in 2015, the broadcaster has been using remote streaming on several occasions, including the 4K broadcast of Carnival in Rio and coverage of the Brazilian Football League.
