Lawo Rocks In Rio
GloboSat has successfully performed 4K Immersive Remote Production for
Rock in Rio with Lawo V__matrix and mc² consoles...

rawing 1.5 million people to its
first instalment in 1985, Rock
in Rio has since ranked among the
world's largest music festivals 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 German IP
broadcast pioneer, Lawo.
Rock in Rio 2019 was a ten-day
event at Barra Olympic Park in Rio
and featured Drake, Foo Fighters,
Bon Jovi, Red Hot Chili Peppers, Iron
Maiden, P!nk and Muse on the Palco
Mundo stage, with Seal & Bahian Xenia,
Whitesnake, Jessie J and Slayer among
the acts rocking the Sunset stage.
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. For producing the 2019 edition
of Rock in Rio, GloboSat furnished a
remote production set-up connecting
the TV compound - a.k.a. "Cidade do
Rock" (Rock City) - at the Barra Olympic
Park with GloboSat's production centre
approximately 15km away via two 2x
80Gbit/s optical fibre paths (Red and
Blue).
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.

Given the relatively small distance,
all 16 cameras and the audio feeds
from the main stage were transmitted
to the TV compound's infrastructure
via SDI. The TV compound's redundant
IP infrastructure was built on Arista
7280 switches and Lawo V__matrix
for converting baseband SDI signals
to IP, processing and compression
of video signals and furnishing the
multiviewers. One of the V__matrix
C100 blades was used to generate
a multiviewer mosaic with 24 PiPs
whose layout was prepared with Lawo's
theWall software. The other softwaredefined C100 blades were dedicated
to processing and conversion tasks.
In total, 28 1080i HD feeds and VC2compressed 4K feeds were used for
the video production. At GloboSat's HQ,
the facility's V__matrix infrastructure
received the HD and 4K feeds plus the

discrete audios from the TV compound
for remote production.
"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."
For monitoring and ensuring signal
integrity of all the ST2110 feeds of the
production, GloboSat utilised Lawo's
smartSCOPE Deep Packet Media
Inspection and Network Analysing
solution. Being installed on a server
at main facility, it also allowed easy
access and on-site monitoring at the
remote TV compound via smartSCOPE's
web interface.
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 complete 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 inside a Lawo mc²96 console
allows to manage up to 256 IP streams,
making it ideal for routing in complex
multi-site audio set-ups.
"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. "One of
the aspects I particularly love about the
Lawo consoles is their authentic, clear
sound that is a faithful reflection of an
instrument's timbre. I suspect this can
be attributed to the manufacturer's
German precision."
The Rock in Rio remote production
was not first of its kind for Globo. Being
renowned for pioneering broadcast
in Brazil with the first broadcast
live in 4K and Dolby Atmos in 2015,
the broadcaster has been utilising
remote broadcast at various occasions
including the 4K broadcast of Carnival
in Rio and the coverage of the Brazil
Football League.
