Brazil's national television network, Rede Legislativa de Rádio e TV, has partnered with Appear to utilize its X5 platform for transmitting legislative channel contributions from Brasília to São Paulo over the public internet. This move is part of Brazil's broader push towards TV 3.0 trials, branded locally as DTV+. The initiative aims to connect parliamentary programming into a next-generation television core without the need for bespoke satellite bookings for each trial window. ### HEVC Plus SRT Over Internet Appear's X5 platform leverages High Efficiency Video Coding (HEVC) compression and Secure Reliable Transport (SRT) protocol, allowing content to be compressed and delivered over ordinary internet paths from Brasília to São Paulo. From there, the content is distributed through CDNs operated by Empresa Brasil de Comunicação (EBC) and the Legislative Assembly of the State of São Paulo. Engineer Luiz Flávio Menezes from the Chamber of Deputies highlighted that the trial validated a practical DTV+ contribution path, ensuring high-quality programming while simplifying operations. Luis Perez, Appear's LATAM sales director, framed this project as proof that broadcasters can adopt efficient IP contribution without waiting for perfect nationwide fiber coverage. ### Why Legislative TV Matters for 3.0 Public channels play a critical role in showcasing the viability of new standards. Any disruptions during plenary sessions could undermine consumer confidence in DTV+ rollouts. By choosing proven SRT over experimental codecs, Rede Legislativa reduces risk while still testing the distribution chains required for TV 3.0. This approach is particularly relevant for vendors selling ATSC 3.0 gear in North America. Many NextGen business cases assume hybrid broadcast-OTT endpoints similar to EBC and ALESP architectures, making Brazil's trials a valuable reference point. ### Integration Guidance Teams benchmarking Appear against rivals should focus on testing jitter buffers for transcontinental internet paths, failover mechanisms when sessions extend past scheduled CDN tokens, and ensuring compatibility with existing monitoring tools like SNMP and Grafana. While Appear did not disclose specific unit counts or contract value, the success of this trial underscores the importance of packet loss recovery and manageable operator training burdens. ### Bottom Line For Brazil's TV 3.0 trials, reliable contribution over IP is crucial before flashy interactive apps become a priority. Appear's Rede Legislativa win signals that SRT remains the preferred protocol for remote production (REMI) even as standards continue to evolve.
