Inside ATSC 3.0 features: what’s behind the broadcast standard

While most viewers focus on the sleek interfaces and user-friendly experiences in OTT, there’s also a sophisticated engine under the hood making it all possible on TV, the ATSC 3.0 standard.

In one of our earlier blog posts, we unpacked the technical leap ATSC 3.0 represents over its predecessor, ATSC 1.0. We won’t rehash those details here — feel free to explore that post for a deeper dive — but today, we’re zooming in on some standout UI features that may showcase ATSC 3.0’s full potential.

If ATSC 1.0 were the seasoned elder son — reliable, familiar, and built for a different era — then ATSC 3.0 would be the ambitious next-generation son: faster, smarter, and brimming with potential. Where the former laid the foundation, the latter is poised to take broadcast technology to a whole new level.

Here’s a quick look at what may make ATSC 3.0 a true over-the-air broadcasting shaker:

  • IP-based architecture — Built on the same internet protocol backbone that powers today’s top streaming services, bringing broadcast TV into the digital-first age.
  • Hybrid OTA + OTT delivery — Seamlessly fuses over-the-air and over-the-top content, bridging the old and new worlds of media consumption.
  • Enhanced audio & video — Delivers ultra-clear video resolutions and immersive, theater-like sound that brings content to life.
  • Future-proof design — Built with adaptability in mind, allowing broadcasters to evolve with emerging tech without needing a total overhaul.

Although the standard is still not mandatory for television broadcasters, it continues to spark extensive debate regarding its potential capabilities and the complexities of its implementation. This raises the question of what discussions and developments are currently unfolding around it.

The UI dilemma — standardization vs. flexibility for networks and affiliates

One of the key NextGen TV debates emerging from NAB 2025 this year revolves around a critical and far-reaching dilemma: should network-affiliated broadcaster apps adopt standardized user interfaces, or should they allow for flexible, station-specific user experiences?

This tension was highlighted in discussions involving major industry players, which are actively advocating for a unified, standardized UI. Their pitch is straightforward: a unified user experience across all affiliated stations reduces friction for the viewer.

But not everyone agrees. The others, for example, argue for maximum flexibility. Local and network broadcasters, they claim, need the freedom to tailor apps to their specific markets, audiences, and brand strategies. A one-size-fits-all approach may work for UI design but could stifle innovation and local relevance — both of which are crucial to retaining and growing audiences in a fragmented media landscape.

There’s also a third perspective — one that questions the very premise of standardization. If every station looks and behaves the same, what happens to differentiation? How can networks compete on innovation, interactivity, and engagement if they are locked into a rigid UI framework? Standardization may ensure consistency, but it could come at the cost of creativity and viewer loyalty. However, the fourth consideration also raises critical questions regarding the UI/UX flexibility — specifically, whether it’s acceptable or user-friendly for viewers to experience interface changes when switching between channels.

These debates represent not just a technical challenge, but strategic crossroads. The broadcast industry has to decide: is it better to prioritize consistency and familiarity, or to embrace diversity and experimentation? The outcome of this choice will shape how audiences experience TV in the next era — and whether broadcasters can truly thrive in an app-first world.

While the conversation is underway, the initial priority is to mandate the transition to ATSC 3.0. Sinclair Broadcast Group has taken a leading role in driving the legal adoption of the standard, also actively demonstrating to the industry what the future of broadcasting could look like with ATSC 3.0.

Bringing streaming-level UX to over-the-air with ATSC 3.0

While many in the industry still view ATSC 3.0’s interactive capabilities as limited or underdeveloped, we set out to challenge this perception. In collaboration with our R&D team — led by Delivery Partnerships and Sales Engineering Manager Oleg Stepanyuk — we’ve worked to push the boundaries of what NextGen TV can deliver. Our goal: to adapt the rich, on-demand, and personalized experiences of OTT streaming into the ATSC 3.0 environment.

Bridging the gap: traditional linear TV vs. ATSC 3.0-based one

For decades, linear television has offered viewers a passive, one-way experience. Content is broadcast on a fixed schedule, and engagement is limited to what is presented on screen. Viewer interaction is essentially non-existent, and personalization is out of reach.

ATSC 3.0 changes this model.

Built on an IP-based infrastructure, ATSC 3.0 merges the reliability of broadcast with the flexibility of broadband. This hybrid approach opens the door to interactive content delivery and viewer personalization that mirrors the functionality of popular OTT platforms.

As we explored the capabilities of ATSC 3.0, we identified several foundational features that broadcasters can implement right away to enhance viewer engagement:

Video on-demand (VOD) content

Benefits for viewers:
  • Watch content on their own schedule — no need to follow a rigid broadcast timetable
  • Access a broader range of content (past episodes, special reports, behind-the-scenes)
  • Improved convenience and control over the viewing experience
Benefits for broadcasters:
  • Increased viewer engagement and time spent on platform
  • Ability to repurpose and monetize existing content libraries
  • More opportunities for ad placements and sponsorships in VOD content

Live “On-Air” interactivity

Benefits for viewers:
  • Engage actively with content through voting, polls, or additional content layers
  • Greater immersion during live events (sports, reality TV, news coverage)
  • Sense of participation and community during real-time broadcasts
Benefits for broadcasters:
  • Boosts viewer retention during live broadcasts
  • Creates new revenue streams through sponsored interactivity
  • Enables valuable real-time data collection on audience preferences and behavior

Targeted advertising

Benefits for viewers:
  • Ads are more relevant and less intrusive, improving overall viewing experience
  • Reduced ad fatigue by seeing fewer, more personalized messages
  • Potential for viewer-controlled ad experiences (choose-your-own-adventure formats, etc.)
Benefits for broadcasters:
  • Higher CPMs (cost per mille) due to improved ad targeting
  • Stronger ROI for advertisers, making the platform more attractive
  • Insight-rich data to refine audience segmentation and campaign performance

Informational widgets (weather, traffic, news)

Benefits for viewers:
  • Instant access to localized, real-time updates without switching channels
  • Context-aware enhancements (e.g., weather during travel segments, traffic during news)
  • Streamlined experience that combines entertainment and utility
Benefits for broadcasters:
  • Increase viewer stickiness by offering added value
  • Opportunities for local sponsorships (e.g., local businesses sponsoring traffic updates)
  • Differentiates the broadcaster’s offering in a competitive market

Informational widgets

How can we resolve the dilemma faced by networks and affiliates — balancing brand differentiation with a seamless user experience?

Nothing communicates this balance more effectively than strong visual design. We build a consistent, intuitive UX across both networks and affiliates within a streamlined broadcaster app, while enabling customized branded experiences. This approach ensures brand uniqueness without compromising usability, effectively satisfying both sides of the equation.

Seamless user experience

Final remarks

While much of the industry is still watching and waiting, forward-thinking leaders are already embracing NextGen TV. Whether to be first or to wait until the ATSC 3.0 protocol becomes a mandated standard — that’s the strategic decision you need to make today. It’s a given.

But making the leap means understanding the ROI of ATSC 3.0 implementation and proactively aligning it with your broadcasting strategy. You don’t have to navigate this alone — partner with experts to move forward with confidence.
