ATSC 3.0 Physical Layer Advances for Final
Brazilian Government Approval
ATSC, the Broadcast Standards Association, today announced that
Brazil’s Fórum do Sistema Brasileiro de TV Digital Terrestre (SBTVD
Forum) has recommended to the Brazilian government the selection of
the ATSC 3.0 “physical layer” as the over-the-air transmission
system for the country’s upgrade to next-generation broadcast
terrestrial “TV 3.0” services. The long-awaited recommendation
follows extensive testing in Brazil to meet the market demands for
the country of more than 200 million people, and reaffirms the
previous selection of several other ATSC technologies for the TV
3.0 system.
ATSC 3.0 suite of standards – the world’s first IP-based system
that marries broadband and broadcast – is already on air in South
Korea, Jamaica, and the U.S., and is coming soon to Trinidad and
Tobago. Other countries are also studying the ATSC 3.0 system
because of its Internet Protocol backbone, spectrum efficiency, and
other advanced features.
On July 22, Brazil’s SBTVD Forum published its final Phase 3
recommendations, and forwarded them to Brazil’s Ministry of
Communications, which will consider the recommendations for
adoption as the country’s TV 3.0 system, including the ATSC 3.0
transmission technology.
“We are deeply gratified by the SBTVD Forum’s recommendation of
the ATSC 3.0 Physical Layer for over-the-air broadcasting,” said
ATSC President Madeleine Noland. “ATSC is also excited about the
opportunity to work with the Forum and Brazilian stakeholders in
fully documenting, developing and deploying TV 3.0 in Brazil. We
have valued the opportunity to share experiences and exchange ideas
with our colleagues in Brazil throughout this four-year selection
process. We have learned a great deal and are looking forward to
continued collaboration. And we are gearing up to showcase ATSC 3.0
at the annual SET Expo broadcast trade show in São Paulo beginning
August 20,” Noland said.
“The recommendations of technologies for TV 3.0 are the result
of four years of exemplary work by the SBTVD Forum in soliciting,
evaluating, and carefully selecting components for TV 3.0,” added
Skip Pizzi, Chair of ATSC’s Brazil Implementation Team. “We’re
proud to see so many elements of ATSC 3.0—in the physical,
transport, and content layers—chosen to become part of Brazil’s
next-gen broadcast TV standard, and we anticipate that the TV 3.0
decisions might ultimately have regional impact beyond Brazil.”
The SBTVD Forum is a non-profit organization of private and
public companies, including broadcasters, manufacturers, software
developers and academia, that advises and makes recommendations to
the Brazilian Ministry of Communications on digital TV technology
and policy matters. Brazil’s “TV 3.0 Project,” which is the Forum’s
title for the country’s next generation of digital TV, includes
both over-the-air broadcast and over-the-top broadband components,
including some optional technologies among the latter. The
recommendations made or reaffirmed on July 22 are the result of a
Call for Proposals and subsequent testing and evaluations conducted
by the Forum since the start of the TV 3.0 Project in July
2020.
The last phase of this process took place from December 2023
until May 2024, as the SBTVD Forum conducted field tests with two
candidate technologies for the physical layer. After a thorough
evaluation, which considered all data collected since the beginning
of the project in 2020, the Technical, Market and Intellectual
Property Modules of the SBTVD Forum unanimously decided to
recommend the ATSC 3.0 Physical Layer to the Ministry of
Communications as the final technology component selection for the
TV 3.0 system.
The recommendation on the ATSC 3.0 Physical Layer transmission
method is in addition to five other key technologies proposed by
ATSC and previously selected by the SBTVD Forum as recommendations
for mandatory inclusion in both the broadcast and broadband
components of the “TV 3.0” system:
- ROUTE/DASH Transport
- MPEG-H Audio
- IMSC1 Captions
- HDR10 High Dynamic Range Video (with optional dynamic HDR
metadata based on SMPTE ST 2094-10 and SMPTE ST 2094-40)
- ATSC 3.0 Advanced Emergency Information
Additional technologies proposed by ATSC were previously
selected for only the TV 3.0 broadband component:
- H.265/HEVC Video Base Layer Encoding
- HLG High Dynamic Range Video (optional)
- SL-HDR1 High Dynamic Range Video (optional)
- AC-4 Audio (optional)
A pronouncement from the Brazilian government on the SBTVD
Forum’s TV 3.0 recommendations is expected soon. Meanwhile, ATSC
has pledged its support to the SBTVD Forum for its ongoing
development of TV 3.0 specifications, recommended practices and
conformance documentation. Brazil’s deployment of TV 3.0 is
expected to begin in 2025.
