HbbTV-TA
8. HbbTV in action: Best practice case studies from across Europe
This article is the eighth in the ‘Understanding HbbTV‘ series, a collection of insights developed by the HbbTV Association to help broadcasters, developers, and technology partners make the most of the HbbTV standard. Each article explores a different aspect of hybrid television: from the core architecture and specification to business models, interoperability, case studies, and the wider regulatory landscape.
The goal of the series is to bridge technical knowledge and real-world practice, showing how HbbTV enables open, scalable, and innovative services that combine the best of broadcast and broadband. Whether you’re building your first HbbTV app or shaping the strategy behind a national service, these articles offer a practical foundation for understanding the standard and its ecosystem.
The HbbTV standard has become the foundation of many of Europe’s most innovative television experiences. From interactive services and audience measurement to addressable advertising and accessibility, broadcasters and platform operators are using HbbTV to enhance viewer engagement and create new business opportunities.
Here are some standout examples of HbbTV in action around the world.
Restart and On-Demand TV: Spain’s LovesTV
A joint initiative by Atresmedia, Mediaset España, and RTVE, LovesTV is one of Europe’s most successful HbbTV-based services. The free-to-air platform offers an enhanced interactive experience that combines live and on-demand viewing.
- Restart a live programme from the beginning
- Watch programmes from the past seven days
- Browse recommendations and upcoming shows
- Explore an improved interactive programme guide
LovesTV demonstrates how HbbTV can unify the broadcast and broadband experience while maintaining the simplicity of traditional TV.
Audience Measurement: Austria’s Teletest 2.0
Austria’s Teletest 2.0 shows how HbbTV data can power next-generation audience measurement. Launched in 2024 by Arbeitsgemeinschaft Teletest (AGTT) and Screenforce Österreich, the system integrates return-path data from over one million HbbTV-enabled devices.
By combining real-time viewing insights with traditional panel data, Teletest 2.0 provides:
- More accurate audience tracking
- Elimination of zero rated shows
- Faster reporting cycles
- Enhanced data for advertisers and agencies
This approach strengthens broadcasters’ understanding of their audiences and showcases the analytical potential of HbbTV.

Unified Streaming and Live TV: The UK’s Freely (OpApp)
In the UK, Freely – launched in 2024 by Everyone TV (a joint venture between BBC, ITV, Channel 4 and Channel 5) – uses the HbbTV Operator Application (OpApp) specification to deliver a seamless, IP-based viewing experience.
Freely allows viewers to switch effortlessly between live and on-demand channels via a unified electronic programme guide (EPG), all streamed over broadband. There’s no need for an aerial — the TV connects via Wi-Fi, showing how HbbTV can power the transition to IP-only television.
This implementation offers a glimpse into the future of free-to-air TV in a connected world.
Addressable and Interactive Advertising
HbbTV enables broadcasters to combine the reach of broadcast with the precision of digital. Across Europe, addressable advertising powered by HbbTV is delivering personalised ad experiences at scale.
- Dynamic ad substitution (DAS) replacing broadcast ads with broadband-targeted ads
- L-shaped banners and on-screen calls-to-action
- Interactive commerce and appointment booking features
In addition to the core HbbTV specification, the DVB Addressable Advertising (DVB-TA) specification defines a common framework for delivering and substituting broadcast and broadband advertisements in a synchronized and standards-based way. It ensures that ad replacement on connected TVs is frame-accurate, seamless, and interoperable across different devices and broadcasters.
In Italy, Mediaset implemented HbbTV-TA in partnership with a major TV manufacturer to guarantee frame-accurate ad replacement and smooth transitions between broadcast and broadband content.
Barker Channels and Enhanced Discovery: ARTE Channel 77
France’s ARTE pioneered the concept of a “barker channel”, an HbbTV service available on DTT channel 77. Viewers can tune directly to this channel or follow a prompt from the main ARTE broadcast to enter a rich HbbTV environment featuring thousands of hours of on-demand content.
The service was authorised by the French media regulator (CSA) and illustrates how HbbTV can extend editorial reach within the regulated broadcast framework.
Accessibility Services in the UK and Germany
HbbTV also plays a key role in making television more inclusive.
In the UK, Freeview Play’s Accessible TV Guide (available on channel 555) provides:
- Filters for subtitles, audio description, and sign language
- High-contrast, zoomed interfaces for legibility
- Optional text-to-speech navigation for blind or partially sighted viewers
Similarly, in Germany, ARD delivers accessibility enhancements via HbbTV, including subtitling, sign-language streams, and synchronised audio description through companion apps. These use cases highlight HbbTV’s flexibility to support diverse accessibility needs and regulatory requirements.
Conclusion
From Spain’s hybrid catch-up services to the UK’s IP-only platforms and Austria’s data-driven measurement, these examples underline the versatility and maturity of HbbTV across Europe. They show how open standards can power both creativity and efficiency, helping broadcasters, manufacturers, and developers deliver the next generation of connected TV experiences.
These international case studies show how broadcasters and platforms are using HbbTV to innovate across content delivery, advertising, and accessibility. But as hybrid TV grows, so does the importance of ensuring that these new services operate within a clear and trusted framework, balancing openness with accountability. In the next article, we explore how policy, regulation, and industry collaboration support a fair and transparent hybrid television ecosystem, helping innovation thrive while maintaining viewer trust and media integrity.
