PODCAST

Powering Next-Generation Broadcast Workflows with AWS, ATSC 3.0, and Zixi

Gustavo Dutra, Business Development Manager for Media & Entertainment, Games & Sports, AWS

Andrew Reich, VP of Business Development, Zixi

Overview
Cloud-based broadcast workflows promise flexibility and scale, but for many broadcasters the real challenge begins at the edge, where cloud infrastructure must reliably feed terrestrial transmission.

In this episode, Andrew Reich, Vice President of Business Development at Zixi, speaks with Gustavo Dutra, Business Development Manager for Media & Entertainment, Games & Sports at AWS, about how broadcasters across Latin America are navigating the transition to IP- and cloud-based architectures. Drawing from a live demonstration at SET Expo in São Paulo, Gustavo explains how AWS and Zixi connected cloud ingest and playout to RF transmitters, and why broadcast-grade IP transport is essential for making cloud broadcast production-ready.

The conversation also explores how Brazil’s new TV 2.0 initiative, based on ATSC 3.0, is accelerating real-world adoption, and how AWS and Zixi are helping traditional broadcasters bridge familiar broadcast models with cloud-native infrastructure, without compromising reliability.

Key Takeaways

  • Cloud workflows succeed or fail at the last mile
    Moving ingest, playout, and processing to the cloud is increasingly common across Latin America, but delivering those workflows into terrestrial transmission remains the defining challenge. Broadcast-grade IP transport between cloud infrastructure and RF transmitters is critical.

  • TV 2.0 is pushing broadcasters from experimentation to deployment
    Brazil’s TV 2.0 framework, built on ATSC 3.0, is accelerating the shift from trials to production planning. Broadcasters are now evaluating how cloud and IP architectures can meet regulatory, operational, and quality requirements at scale.

  • Open-source transport has limits in broadcast delivery
    Contribution-grade and broadcast-grade transport are not the same. SRT-based tools are widely used for contribution, but the SET Expo workflow highlighted where broadcast delivery raises the bar. Feeding terrestrial transmitters requires predictable performance and sustained packet integrity, particularly in cloud-to-RF architectures.

  • Zixi enabled a production-ready cloud-to-transmitter workflow
    During the live SET Expo demonstration, Zixi provided the reliable IP transport needed to stabilize delivery into terrestrial transmission. Once introduced, the workflow operated successfully under real show conditions.

  • Fast integration matters when everything is live
    Zixi was integrated quickly during show preparation, resolving architectural issues in real time. The ability to deploy and trust transport under pressure proved essential to the success of the demonstration.

  • Cloud adoption works best when broadcast models are respected
    AWS’s approach reflects a broader industry reality: broadcasters adopt cloud more confidently when familiar broadcast architectures are preserved, while still benefiting from cloud scalability and resiliency.

  • Partnerships make cloud broadcast production-ready
    The SET Expo workflow demonstrated the importance of ISV partnerships. As a key AWS partner in Latin America, Zixi enables reliable transport within cloud-based broadcast architectures broadcasters are preparing to deploy at scale.
