HEVC and SRT Carry Brazil's TV 3.0 Trials Over Public Internet
Rede Legislativa deployed Appear's X5 hardware to transport live signals over the public internet using HEVC compression and SRT for Brazil's TV 3.0 trials. The contribution architecture connects Brasília to two CDNs in São Paulo, demonstrating a cost-efficient model for linking broadcast operations to next-generation television infrastructure.
Key Takeaways
- X5 uses HEVC compression and SRT to carry live signals over the public internet between Brasília and São Paulo
- Architecture delivers content simultaneously to two CDNs operated by EBC and ALESP (Legislative Assembly of São Paulo)
- Brazil's TV 3.0 standard was formally regulated in August 2025; Chamber of Deputies hosted experimental DTV+ demonstrations in 2026
- Deployment lets Rede Legislativa connect existing broadcast operations to the new TV 3.0 delivery environment without building dedicated transmission infrastructure
Why It Matters
The deployment shows broadcasters entering Brazil's TV 3.0 ecosystem can bridge existing IP contribution infrastructure to the new delivery standard without building dedicated transmission from scratch. As DTV+ moves from trial to commercial deployment — Globo launched consumer services in three cities on June 11, 2026 — the contribution layer becomes a critical integration point for hardware vendors like Appear. Watch whether other Brazilian broadcasters adopt similar SRT-over-public-internet contribution models as TV 3.0 expands beyond its initial launch cities.
Additional Context
Brazil's TV 3.0 program reached a commercial milestone on June 11, 2026, when Globo launched the first consumer DTV+ services in Rio de Janeiro, São Paulo, and Brasília, timed with the opening of the World Cup. Per Brazil's Ministry of Communications, more than 21 million Brazilians now have access to the experimental TV 3.0 signal, with viewers required to purchase a converter to experience full interactivity features. The launch marked the transition from specification and field trials to consumer deployment, with the first DTV+ compatible set-top boxes and television sets entering the market. The DTV+ platform is built on the ATSC 3.0 physical layer with Brazilian innovations and is the world's first large-scale television deployment to mandate UHD 4K/HDR video and immersive audio as a base service. Per V-Nova, June 2026, DTV+ uses VVC and MPEG-5 LCEVC codecs to deliver 4Kp60 HDR channels at under 10 Mbps over existing terrestrial broadcast infrastructure. The standard was formally regulated by Brazilian Decree No. 12.595 on August 27, 2025, which established the transition framework and allocated spectrum in the 216–372 MHz range. Appear's X5 platform, used in the Rede Legislativa deployment, became generally available at NAB Show 2026 in April, per Appear's announcement. The compact 1RU half-rack device supports HEVC encoding and decoding, accelerated SRT, and ST 2022-7 protection, positioning it for edge contribution scenarios where space and cost constraints rule out larger chassis like the X10 or X20. The Rede Legislativa trial is among the early real-world deployments of the X5 since its general availability.
