Appear has announced its role in supporting Rede Legislativa de Rádio e TV’s contribution workflow for Brazil’s TV 3.0 activities, as the country advances experimental transmissions of the new standard, locally branded as DTV+. The deployment uses Appear’s X5 to transport the broadcaster’s signal from Brasília to the TV 3.0 core infrastructure in São Paulo, as part of the Rede Legislativa trials designed to shape the next phase of Brazilian television.

Brazil’s TV 3.0 programme has gathered momentum since the technology was formally regulated in August 2025. In 2026, the Chamber of Deputies hosted experimental demonstrations of DTV+ and the Mais BR public-channel platform, while Empresa Brasil de Comunicação (EBC) confirmed its role in the first public presentation of the TV 3.0 platform. Earlier this year, EBC and the Chamber were authorised to use test stations in Brasília and São Paulo for continuous TV 3.0 transmissions.

In the Rede Legislativa workflow, Appear’s X5 uses HEVC compression and Secure Reliable Transport (SRT) to carry the signal over the public internet from Brasília to São Paulo. The architecture is designed to deliver the content simultaneously to two CDNs operated by the EBC and ALESP (Legislative Assembly of the State of São Paulo). The project highlights how proven IP contribution technologies can support the operational requirements of Brazil’s emerging TV 3.0 services.

For Rede Legislativa, the deployment provides a practical and cost-efficient way to connect existing broadcast operations into a new delivery environment without requiring a bespoke TV 3.0 transmission platform.

“The trial has given us an efficient and reliable way to connect Brasília to the TV 3.0 core infrastructure in São Paulo,” said Luiz Flávio Menezes, Engineer, Chamber of Deputies, Brazilian National Congress. “Appear’s X Platform has helped us validate a practical contribution architecture for DTV+, preserving quality while simplifying operations as we evaluate how next-generation television services can be best delivered in Brazil.”
