Apr.25.2022

WASHINGTON, DC – The Advanced Television Systems Committee (ATSC) announced today that the Brazilian Digital Terrestrial Television Systems Forum has recommended to the Brazilian government the selection of several technologies proposed by ATSC for Brazil’s next-generation digital terrestrial television standard.

The ATSC 3.0 elements selected by the Forum, and others still under consideration, are proven technologies in the ATSC 3.0 suite of standards – the world’s first IP-based system combining broadband and broadcast.

“ATSC commends the Forum for the well-organized development of the Brazilian TV 3.0 system,” said ATSC President. “Over the past ten years, ATSC members have developed the ATSC 3.0 system, and I am very proud that, after rigorous testing and evaluation in Brazil, many elements of ATSC’s state-of-the-art terrestrial broadcast system have been selected. ATSC is ready Support the SBTVD Forum as it applies these technologies to Brazil’s unique needs.” Noland also congratulated the ATSC IT-4 Brazil Implementation Team. “IT-4 members have been working hard to support ATSC technology throughout the process and will continue to do so during the upcoming SBTVD assessment process.”

While development of the “TV 3.0″ specification and some additional testing will continue over the next two years, the decisions made so far select five key technologies proposed by the ATSC for the broadcast and broadband components of the “TV 3.0″ system:

Route/Sprint Transport

MPEG-H audio

IMSC1 subtitles

HDR10 Video High Dynamic Range EOTF (with optional dynamic HDR metadata based on SMPTE ST 2094-10 and SMPTE ST 2094-40)

ATSC 3.0 Advanced Emergency Alert

Other technologies proposed by ATSC are specific to TV 3.0 broadband components:

265/HEVC video base layer encoding

HLG Video High Dynamic Range EOTF (optional)

SL-HDR1 high dynamic range transmission (optional)

AC-4 audio (optional)

Brazil plans to start deploying its TV 3.0 system in 2024. It recommends that the wireless physical layer and some application coding (i.e. interactive) elements continue to be tested and evaluated in 2022-23. TV 3.0 system. The ATSC proposal for the ATSC 3.0 Physical Layer and ATSC 3.0 Interactive Content System is still subject to further evaluation.
