Appear Supports Rede Legislativa’s Contribution Workflow for Brazil’s TV 3.0 Trials – Sports Video Group

Appear ASA has announced its role in Rede Legislativa de Rádio e TV’s contribution workflow for Brazil’s TV 3.0 trials, known locally as DTV+. The deployment uses Appear’s X5 to transport the broadcaster’s signal from Brasília to TV 3.0 core infrastructure in São Paulo, delivering content simultaneously to two CDNs operated by EBC and ALESP (Legislative Assembly of the State of São Paulo).

The X5 uses HEVC compression and Secure Reliable Transport (SRT) to carry the signal over the public internet. Brazil’s TV 3.0 programme was formally regulated in August 2025, with the Chamber of Deputies hosting experimental DTV+ demonstrations in 2026 and EBC and the Chamber authorized to use test stations in Brasília and São Paulo for continuous TV 3.0 transmissions.

“Brazil’s move towards TV 3.0 is creating new requirements not only in transmission, but also in the contribution workflows that feed it,” says Luis Perez, Sales Director LATAM, 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.”

“The trial has given us an efficient and reliable way to connect Brasília to the TV 3.0 core infrastructure in São Paulo,” says 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.”
