Appear Supports Brazil's TV 3.0 Trials

Appear ASA, a global provider of live production technology, has announced its involvement in supporting Rede Legislativa de Rádio e TV's contribution workflow for Brazil's TV 3.0 programme as the country continues experimental transmissions of its next-generation television standard, branded locally as DTV+.

The deployment uses Appear's X5 platform to transport broadcast signals from Brasília to the TV 3.0 core infrastructure in São Paulo as part of Rede Legislativa's trials, which aim to help define the future architecture of Brazilian television services.

Brazil's TV 3.0 initiative has accelerated since the standard was formally regulated in August 2025. In 2026, the Chamber of Deputies conducted public demonstrations of DTV+ and the Mais BR public-channel platform, while Empresa Brasil de Comunicação (EBC) participated in the first public presentation of the TV 3.0 system. Earlier this year, both EBC and the Chamber were authorised to operate test transmission stations in Brasília and São Paulo for ongoing TV 3.0 trials.

Within the Rede Legislativa workflow, Appear’s X5 uses HEVC compression alongside Secure Reliable Transport (SRT) to deliver signals over the public internet between Brasília and São Paulo. The content is then distributed simultaneously to two CDNs operated by EBC and ALESP (Legislative Assembly of the State of São Paulo).

The project is designed to demonstrate how IP-based contribution technologies can support the operational requirements of emerging TV 3.0 services, while providing a more efficient and cost-effective alternative to bespoke transmission infrastructure.

For Rede Legislativa, the system provides a practical method of integrating existing broadcast operations into the new TV 3.0 environment without the need for a dedicated end-to-end transmission platform.

"Brazil's move towards TV 3.0 is creating new requirements not only in transmission, but also in the contribution workflows that feed it," said Luis Perez, Sales Director LATAM at Appear. "In this project, our hardware-accelerated SRT technology enables Rede Legislativa to transport high-quality signals securely and reliably from Brasília to São Paulo over the public internet. It demonstrates how broadcasters can use new efficient technologies, such as SRT, to support the next wave of television services in Brazil with the low latency, high density and resilience needed for modern production workflows."
