HbbTV and DVB-I: Complementary standards driving the next generation of television

The relationship between HbbTV and DVB-I is moving from theory to reality. As the first regular DVB-I deployments gather pace, broadcasters, manufacturers and technology providers are demonstrating how they work together to create a more unified, discoverable and future-proof television experience.

This was the focus of the latest HbbTV webinar, held on 22 July 2026, which brought together experts from across the DVB-I ecosystem to examine real-world deployments in Europe and beyond. The session featured William Cooper (Service List Registry), Frank Heineberg (RTL Deutschland), Stefano Braghieri (RTI-Mediaset), Ersoy Özdemir (Vestel International), and moderator Jörn Krieger, offering perspectives from platform providers, broadcasters and device manufacturers. Watch the webinar recording here and access the presentations here.

Rather than discussing DVB-I as a future concept, the webinar highlighted deployments already underway or close to rollout in New Zealand, Australia, Germany and Italy, showing how HbbTV has become an essential component of many DVB-I implementations.

Simplifying television in a fragmented world

Opening the webinar, William Cooper, Founder & CEO of Service List Registry (SLR), described the challenge facing today’s television industry.

Viewers now have more content available than ever before but discovering that content has become increasingly difficult. Broadcast channels, streaming services, FAST channels and on-demand libraries are spread across multiple platforms and user interfaces, creating a fragmented viewing experience. At the same time, broadcasters face growing competition from global streaming platforms while device manufacturers seek ways to deliver richer user experiences.

Cooper argued that distribution alone is no longer enough.

“Discovery delivers distribution” has become the defining principle. Content must not only be available, but it must also be easy for viewers to find.

This is where DVB-I and HbbTV work together.

DVB-I provides the service discovery layer. It describes television services using metadata, allowing receivers to discover broadcast and IP-delivered services through unified service lists.

HbbTV provides the application and presentation layer. Using familiar web technologies such as HTML, JavaScript and CSS, it enables broadcasters to deliver branded user experiences, programme guides and interactive services.

Together they provide a platform that allows viewers to access television services regardless of whether they are delivered via terrestrial, satellite, cable or broadband networks.

Cooper stressed that these are complementary technologies rather than competing standards, each solving different parts of the television experience. 

New Zealand prepares one of the first national DVB-I launches

One of the most significant announcements during the webinar was the progress being made in New Zealand.

Building on its established HbbTV ecosystem, Freeview New Zealand is preparing to launch Freeview NextGen in Q3 2026, combining DVB-I service discovery with HbbTV to provide viewers with a unified television experience.

Rather than requiring viewers to understand how content is delivered, DVB-I allows services received via terrestrial broadcast, satellite, cable or broadband to appear together in a single service list.

A persistent HbbTV application provides the programme guide and user interface across all services, creating a consistent viewing experience while remaining integrated into the television’s native interface.

According to Cooper, the service is expected to launch with support from television manufacturers including Hisense and TCL, potentially making New Zealand one of the world’s first markets to deploy DVB-I as a national consumer service. 

Germany moves towards commercial rollout

Frank Heineberg, VP Standards & Innovations at RTL Deutschland, provided an update on Germany’s ambitious DVB-I rollout, currently targeted for autumn 2026.

Germany’s approach has been notable for its collaborative structure.

Following successful pilot activities beginning in 2023, the  Bavarian Regulatory Authority for New Media (BLM) convened a DVB-I roundtable in 2024.  The DVB-I Round Table is bringing together key stakeholders from across the media ecosystem to prepare the market launch of DVB-I in Germany. Participants include ARD, ZDF, RTL Deutschland, Seven.One Entertainment Group, VAUNET, ZVEI and the Bundesnetzagentur (Federal Network Agency), while BLM serves as moderator.

One major milestone has been the publication of the DVB-I Book Germany,  a key component of which is the Technical Implementation Profile, developed by the DVB-I Task Force of the Deutsche TV-Plattform (DTVP).

These documents define the technical, regulatory and organisational framework for deployment, including device requirements, service onboarding, certification processes and the national service list.

Rather than attempting to launch every possible feature on day one, Germany is adopting a Minimum Viable Product (MVP) strategy, establishing a robust baseline platform before introducing additional functionality over time.

Heineberg also explained how Germany’s service list will organise services into logical categories covering public service broadcasters, commercial broadcasters, regional services, international channels and radio services.

This structure aims to make navigation intuitive while accommodating the wide variety of television services available in the German market. 

HbbTV plays a central role

Although DVB-I receives much of the attention, Heineberg emphasised that HbbTV remains fundamental to the German deployment.

The German DVB-I profile requires receivers to support both DVB-I and HbbTV, with HbbTV enabling several important capabilities beyond basic service discovery.

These include:

  • linked applications for advanced media presentation
  • DRM-enabled commercial services
  • consistent interactive experiences across broadcasters
  • support for broadcaster applications launched from DVB-I services.

One notable observation was that disabling HbbTV on compatible receivers could prevent certain DVB-I services from operating correctly, underlining just how closely the two technologies are becoming integrated.

For Germany, HbbTV is not an optional enhancement, it is an essential component of the overall DVB-I experience. 

Italy builds on years of practical experience

Italy has been one of Europe’s earliest DVB-I adopters, with trials running since 2023.

Stefano Braghieri of RTI-Mediaset explained why HbbTV remains central to the Italian implementation.

While DVB-I provides service discovery, broadcasters still require capabilities that today are best delivered through HbbTV applications.

These include DRM-based content protection, premium content access, JavaScript-based DASH playback, quality-of-service monitoring and addressable advertising.

Braghieri highlighted that broadcasters also need to preserve existing commercial models developed around HbbTV applications already deployed on digital terrestrial television.

Rather than creating separate experiences, broadcasters are working towards a single HbbTV application capable of operating across both broadcast and broadband-delivered services.

This approach maintains consistent branding and user experience regardless of how content reaches the television.

Italy is also using HbbTV applications to satisfy regulatory requirements, including obtaining user consent before switching viewers to broadband-delivered content where necessary. 

Trials move towards commercial services

The Italian DVB-I trial has demonstrated that DVB-I can coexist successfully with existing broadcast infrastructure without disrupting terrestrial television services.

Several important building blocks are already in place.

An Italian implementation profile has been published through the UHD Book, defining receiver requirements while remaining closely aligned with work undertaken in Germany to minimise market fragmentation.

An independent Service List Registry is already operating, while a third-party certification process ensures compatible receivers can access Italian DVB-I services.

Meanwhile, Italy’s communications regulator AGCOM has begun work on the regulatory framework required to support commercial deployment, recognising that DVB-I must integrate into an already well-established digital television ecosystem rather than replacing it.

The focus now shifts from proving the technology to creating the commercial and regulatory environment needed for national rollout. 

A manufacturer’s perspective

Ersoy Özdemir, TV Business Development Manager at Vestel International, offered valuable insight into DVB-I from the perspective of a television manufacturer.

Vestel began developing DVB-I support as early as 2021 through specialist engineering teams already experienced in HbbTV and Freeview Play.

Early involvement allowed Vestel to participate in proof-of-concept activities and broadcaster trials across multiple countries, including Italy, Finland, Ireland, Spain, Australia and New Zealand.

This practical experience reinforced several important lessons.

Firstly, successful DVB-I deployment depends on close collaboration between broadcasters, manufacturers and platform operators.

Secondly, while standards and test suites provide an essential foundation, real broadcaster services remain vital for uncovering interoperability issues that only emerge during practical deployment.

Finally, consumers benefit directly through simpler setup, richer service information and consistent interactive experiences.

Özdemir described HbbTV and DVB-I as complementary technologies, with DVB-I providing the discovery foundation while HbbTV delivers the rich interactive experiences that viewers increasingly expect.

Manufacturers, he concluded, play a critical role by transforming open standards into products that consumers can actually buy and use. 

Collaboration emerges as the common theme

Although the presentations covered different countries and perspectives, several consistent themes emerged throughout the webinar.

The first is that DVB-I is no longer an experimental technology. Multiple markets now have operational trials, implementation profiles and clear commercial deployment plans.

Secondly, HbbTV has established itself as a strategic partner to DVB-I rather than an alternative. Broadcasters repeatedly demonstrated how HbbTV applications provide the functionality needed to support DRM, advertising, service presentation and user interaction.

Finally, successful deployment depends on industry collaboration.

Broadcasters, manufacturers, regulators, standards organisations and technology suppliers all have distinct roles to play. Markets such as Germany and Italy have demonstrated that building consensus across these groups is as important as solving the technical challenges themselves.

Looking ahead

The webinar painted a picture of an ecosystem entering a new phase.

After several years focused on standards development, proof-of-concepts and technical trials, attention is now shifting towards commercial deployment.

New Zealand appears poised to become one of the first markets to launch a national DVB-I service. Germany is targeting commercial rollout later this year, while Italy continues to mature one of Europe’s most advanced trial environments. Manufacturers are already integrating DVB-I capabilities into commercial products, and broadcasters are refining the operational models needed for long-term success.

Perhaps the strongest message from the webinar was that HbbTV and DVB-I each fulfil distinct but complementary roles within the television ecosystem. DVB-I provides a standardised approach to service discovery and metadata, while HbbTV delivers the application environment that enables rich user experiences, interactivity and advanced broadcaster services. Together they create a unified framework that allows television services to span both broadcast and broadband networks seamlessly.

As deployments accelerate over the coming months, broadcasters, manufacturers and technology providers are demonstrating how these complementary standards can work together to simplify service discovery, preserve broadcaster prominence on TV screens and deliver a consistent viewing experience across an increasingly hybrid television landscape.

Reimagining satellite TV with DVB-I and HbbTV

This article is part of a series based on presentations from the HbbTV Symposium and Awards 2025, bringing together insights from across the industry on the future of broadcast services and connected television. Covering topics from broadband-only delivery and addressable advertising to interoperability and evolving standards, the series captures key discussions and expert perspectives shaping the next phase of HbbTV and the wider TV ecosystem.

Ralph Edeine, Eutelsat
Ralph Edeine, Director D2C Platform & Advanced TV Solutions at Eutelsat

At the HbbTV Symposium 2025, Ralph Edeine, Director D2C Platform & Advanced TV Solutions at Eutelsat, presented a vision for the future of satellite television, one that combines the scale and reliability of broadcast with the flexibility and intelligence of IP-based services.

His starting point was a recognition of both strength and challenge. Satellite remains one of the most powerful distribution platforms in the world, reaching millions of households and delivering thousands of television and radio channels. However, the rapid rise of OTT services has fundamentally changed viewer expectations, particularly in areas such as user experience, content discovery and interactivity.

As Edeine noted, the best user experiences today are often found in streaming applications, where interfaces are rich, personalised and easy to navigate. For satellite operators, this creates an urgent need to evolve.

The approach taken by Eutelsat is to embrace hybrid delivery, combining broadcast with broadband through open standards. Rather than developing proprietary solutions, the company has chosen to build on DVB-I for service discovery and HbbTV for user experience and interactivity.

DVB-I plays a central role in this architecture. It enables the creation of unified service lists that can include both broadcast and OTT channels, simplifying installation and improving navigation. For satellite services, this removes traditional limitations such as long channel scans and inconsistent channel ordering. With DVB-I, hundreds or even thousands of channels can be installed and organised in seconds, with rich metadata integrated directly into the device interface.

HbbTV complements this by enhancing the user experience. It enables the delivery of electronic programme guides, interactive features and additional services that bring satellite viewing closer to the expectations set by streaming platforms. Together, DVB-I and HbbTV create a consistent and modern interface across both connected and non-connected environments.

A key example of this approach is the Sat.tv Connect service. Designed to improve the user experience of free-to-air satellite television, it combines DVB-I service discovery with HbbTV-based interfaces to deliver structured channel lists, enriched programme guides and additional features.

This represents a significant step forward from traditional satellite experiences, where channels are often presented in random order with limited metadata. By organising content by language or region and providing a full electronic programme guide, the platform makes it easier for viewers to discover and navigate content.

Importantly, the solution is designed to work across a wide range of devices. For non-connected markets, low-cost set-top boxes can deliver a basic enhanced experience using broadcast data. For connected TVs and hybrid devices, DVB-I and HbbTV enable a more advanced and flexible interface, fully aligned with open standards.

Beyond user experience, monetisation is a critical driver. Edeine highlighted how HbbTV enables the introduction of analytics and advertising capabilities into satellite environments. By embedding tracking mechanisms within applications, broadcasters can gain insight into audience behaviour, including viewing patterns and geographic distribution.

This data forms the foundation for more advanced services, including addressable advertising. By combining the reach of satellite with the precision of digital advertising, broadcasters can create new revenue streams and improve the effectiveness of their campaigns.

The integration of FAST channels is another example of this hybrid model in action. By referencing streaming-based channels within the satellite service lineup, platforms can expand their content offering and increase visibility for new services, while maintaining the scale of broadcast distribution.

Looking ahead, Edeine positioned hybrid delivery as a key step in the broader transition towards IP-based television. While full IP distribution remains a longer-term goal, technologies such as DVB-I and HbbTV provide a practical pathway, enabling gradual evolution without disrupting existing services.

His conclusion was clear. The future of satellite television is not about replacing broadcast, but enhancing it. By combining broadcast reliability with broadband intelligence, hybrid solutions can deliver a more engaging, measurable and monetisable viewing experience.

In this model, satellite does not compete with streaming. Instead, it becomes a complementary platform, capable of delivering both scale and sophistication in an increasingly connected television ecosystem.

Industry debates future of broadcasting at DVB World 2026

The DVB World 2026 conference on 17-18 March in Amsterdam centred on the transition from traditional broadcasting to IP-based delivery, with DVB Chair Remo Vogel (rbb/ARD), emphasising the importance of a managed migration that preserves an open ecosystem for devices and services.

In his keynote, Vogel (pictured) said with video delivery migrating to the web, DVB-I would be the “glue for a hybrid world” that connects broadcast and broadband environments. The approach aims to avoid market fragmentation while maintaining universal access and service prominence.

The importance of DVB-I as a future delivery framework was underlined by confirmation that New Zealand plans a nationwide deployment of the standard this year. In Europe, Rainer Biehn (bmt) reported that Germany’s DVB-I round table, comprising public and commercial broadcasters, regulators and industry bodies, is targeting a market introduction in September 2026.

Further rollouts are also in preparation elsewhere. Jim Higgins (RTÉ) announced a DVB-I trial in Ireland starting in June, running until November with technically experienced participants to gather operational insights.

Beyond distribution, speakers highlighted a broader transformation of media technology. Antonio Arcidiacono (EBU) described the next phase as a shift “from transport to intelligence”, driven by network-level capabilities and local AI-generated services.

In fact, AI emerged as a significant theme in discussions across the conference. The integration of AI capabilities directly into TV sets could unlock a range of new opportunities, from radically different video compression models to advanced personalisation where consumer data can be processed locally without leaving the device.

From a user perspective, Adde Granberg (SVT) argued that success will depend on viewer experience rather than technical optimisation. Referencing the rapid growth of creator-led platforms, he suggested that “one-to-many” broadcasting should evolve into “one-to-meaningful” engagement and predicted that traditional broadcasting structures may not survive in their current form.

Other speakers addressed the role of DVB-I within an increasingly platform-driven environment. Ralph Edeine (Eutelsat) said the standard will help ensure satellite services remain visible in interface-led user environments. Salvatore Martino (Kineton) argued that centralised aggregation represents the only sustainable route for local broadcasters, while also highlighting challenges around stream authenticity.

On the device and ecosystem side, Vincent Grivet (HbbTV Association) said fragmentation remains a core issue in the connected TV market, with broadcasters required to maintain multiple applications across “walled garden” platforms. He positioned HbbTV and DVB-I as complementary solutions, with HbbTV unifying devices and DVB-I harmonising networks and content sources.

While the conference focused strongly on DVB-I and the transition to IP delivery, discussions on the DVB World show floor also highlighted that HbbTV retains  critical relevance in an all-IP environment, as illustrated by platform initiatives such as Freely in the UK. Participants further noted that HbbTV is widely regarded as the natural application layer for DVB-I, with the two standards closely interlinked in practical deployments, as DVB-I relies on HbbTV capabilities in several areas.

The developer perspective was addressed in a special session on building DVB-I applications. Hyunmin Jeon, winner of the DVB-I UI competition, presented an Android-based app that applies familiar streaming user experience patterns while leveraging DVB-I metadata. She also announced that the application’s source code will be made publicly available.

Looking beyond current deployments, Thomas Stockhammer (Qualcomm) commented on 5G Broadcast, noting that audiences are ultimately seeking compelling experiences rather than underlying technologies.

The second day of the conference was again held as an “unconference” format, allowing participants to explore topics such as DVB-I implementation challenges in more depth through interactive discussions.

Across sessions, a consistent theme emerged: while the migration to IP delivery is widely accepted as inevitable, the industry is still defining how to balance technological innovation, user experience and the preservation of open, interoperable ecosystems.

HbbTV Association publishes HbbTV 2.0.5 core specification

Geneva, 2 March 2026 – The HbbTV Association, a global initiative dedicated to providing open standards for advanced interactive TV services via broadcast and broadband networks, has published version 2.0.5 of its core specification, marking a major step in the evolution of the HbbTV standard. The specification was approved at the latest meeting of the HbbTV Steering Group.

HbbTV 2.0.5 is an incremental update to HbbTV 2.0.4, published two years ago, and represents a significant technical advancement for hybrid and interactive television services. The most notable change is the formal integration of Digital Rights Management (DRM) into the core specification. While HbbTV devices have supported DRM for many years, this is the first time it has been explicitly defined, providing a harmonised, interoperable approach across the ecosystem. Support for at least one of the DRM systems listed in the HbbTV DRM specification published six months ago – Microsoft PlayReady or Google Widevine – is required. This formalisation is essential for enabling secure delivery of premium content and meeting the requirements of broadcasters, platform operators, rights holders, and content owners, ensuring a compelling experience for viewers.

WebAssembly support, already present to some extent in HbbTV devices via browser engines such as Chrome or WebKit, is now formally included in the specification. This allows advanced features such as efficient decoding of auxiliary video streams, including sign language services demonstrated by Catalan public broadcaster 3Cat at trade shows IBC 2025 and HbbTV Symposium and Awards 2025. Additional web security measures have been incorporated, and support for the VVC and AV1 video codecs has been defined, although implementation of these codecs is optional. Several simplifications for implementers have also been introduced: unused features have been removed, others marked for deprecation, and some requirements relaxed to improve interoperability.

The integration between HbbTV and DVB-I introduced in HbbTV 2.0.4 is further improved in 2.0.5. The specification now clarifies how DVB-I applications associated with entire service lists can be supported, enabling platforms or service aggregators to obtain GDPR consent or agreement to terms and conditions. Implementation feedback, particularly regarding HbbTV and DVB-I integration, has resulted in numerous technical corrections being included.

The HbbTV Association plans to issue a Request for Proposals (RfP) in the coming weeks to extend its Conformance Test Suite to support HbbTV 2.0.5.

“HbbTV 2.0.5 represents an important step forward in the evolution of hybrid TV services,” said Vincent Grivet, Chair of the HbbTV Association. “With formalised DRM, support for next-generation codecs such as AV1 and VVC, enhanced DVB-I integration, and WebAssembly capabilities, the specification aligns to the most recent and impacting market trends, enabling more sophisticated, secure and feature-rich services. It demonstrates HbbTV’s continued commitment to advancing the connected TV ecosystem for broadcasters, platform operators, content owners and viewers alike.”

The HbbTV 2.0.5 specification and an associated explainer document are now available in the HbbTV Resource Library.

    • Playback: Enable seamless audio/video playback—whether via HbbTV APIs (for your HbbTV app) or native integration on other platforms.
  3. Walk-through video
    Include a short demonstration video showing your UI in action. This helps judges, who can’t interact directly with your applcation, understand workflows and key features that might not be obvious from screenshots alone.
  4. Cross-platform or experimental UIs
    While a traditional grid-based user experience is perfectly valid, you’re also encouraged to explore:
    • Voice or screen-reader–driven experiences.
    • AI-powered personalization.
    • Multiscreen or second-screen integrations.
  5. Accessibility & innovation
    Judges will score entries on these five criteria (each worth 20%):
    • User Experience & Usability
    • Accessibility
    • Usage of DVB-I Specification
    • Innovation
    • Design & Visual Appeal

Make sure your HbbTV client adheres to HbbTV best practices for accessibility (e.g., high-contrast modes, subtitle support, screen-reader compatibility) to score well in those categories.

The competition is open to both OpApp and standard HbbTV applications. While DVB-I based application may more naturally be OpApp, building similar experiences as standard HbbTV applications is acceptable and expected. 

Building an OpApp will require that a developer has access to an HbbTV OpApp development environment. 

Resources & support

To help HbbTV developers get started and stay on track, the DVB Project has committed to providing the following resources. As soon as each becomes available, links, documentation, or reference implementations will be posted in the #dvb-i-competition channel on the HbbTV Developer Slack:

Tips for success

  • Emphasize HbbTV strengths:
    Leverage HbbTV’s support for HTML5, JavaScript, and broadcast-broadband hybrid workflows, while integrating DVB-I’s dynamic service lists. 
  • Prioritize accessibility:
    Ensure screen-reader compatibility, provide closed captions, and design for low-vision users. Accessibility accounts for 20% of the judging criteria, so your efforts here will pay off.
  • Innovate beyond the basics:
    Consider voice controls (via integrated microphones), personalized recommendations (using simple AI/ML modules), or context-aware features. While DVB-I specifies how to retrieve and parse service data, nothing limits you from building cutting-edge UI features on top of it.
  • Engage with the community early:
    Posting your design mockups in Slack can open up new ideas, perhaps a fellow HbbTV developer has experience integrating DVB-I EPG data, or someone else can suggest UI patterns that make your interface stand out.
  • Document & demo thoroughly:
    The judges will rely heavily on your walk-through video. Show clearly how to navigate services, access the service and program data, and start playback. If your HbbTV app has unique accessibility features (e.g., custom subtitles, high-contrast skins), highlight them explicitly.

Next steps & call to action

Exploring the Role of HbbTV in the DVB-I Environment

In the rapidly evolving world of digital broadcasting, the intersection of traditional broadcast technologies and modern internet-based solutions has become a focal point. The DVB-I standard, which aims to bring the familiar linear TV experience to IP-based networks, has introduced new opportunities and challenges for broadcasters. One of the critical elements in this hybrid ecosystem is the integration of DVB-I with HbbTV. This article looks closely at the relationship between HbbTV and DVB-I, exploring their synergy, technical challenges, and the potential impact on the future of television.

Understanding DVB-I and HbbTV

DVB-I extends the traditional linear TV model to IP networks, providing a seamless, high-quality viewing experience across a wide range of devices. Unlike conventional broadcast systems, it relies on streaming (e.g. DVB-DASH) for content delivery. 

HbbTV, has emerged as a critical component for enhancing the functionality and user experience of digital TV. It acts as an application layer, bridging between broadcast and broadband content, enabling features like interactive advertising, on-demand streaming, and advanced user interfaces. 

As broadcasters and service providers launch DVB-I based streaming services, HbbTV plays as vital a role in extending the capabilities of those DVB-I-based services as it does today for traditional broadcast services.

The Complementary Relationship

The relationship between HbbTV and DVB-I has become increasingly intertwined. DVB-I has the concept of “Linked Applications,” allowing broadcasters to associate HTML5-based applications (including HbbTV) directly with TV channels and services. This integration enables applications to enhance live and on-demand content with interactive elements, personalized recommendations, and addressable advertising.

In the DVB-I specification clauses “5.1.6” “5.2.3” provide mechanisms to associate an application (e.g. HbbTV) to DVB-I ecosystem. There are a number of different application types as detailed in the table below.

TypeApplication typeWhen startedNote
1.1App. with media in parallelWhen service instance is selectedThe application runs “on top” of the contentIt corresponds to the usual “red button” application
1.2App. controlling media presentationWhen service instance is selectedThe application manages the content play.It can rely on HbbTV player (e.g. HTML5) or integrated library (e.g. dash.js)
1.3App. in series with mediaWhen service instance is selected unless a previous execution of the application returned the persistent key.The application is not intended for playing video but for more platform-specific topics (e.g. GDPR consent, single sign-on and some variants of DRM license acquisition). It can be used in combination with a type 1.1 or a type 1.2 app to keep the two sets of functionality in separate apps or developed by separate teams
2Outside of availability window1) When service is selected and all instances are outside their availability window.2) When all service instances of currently selected service become outside their availability window(s).The application provide User a better UEX than a «black screen» or a «fixed info screen»
3Service provider home pageUser selection from DVB-I player UI.The application is launched from native UI, e.g. EPG or Info-banner
4.1Service list installationDuring service list installation process.The application could manage regulated access to particular ServiceList — agreement or consent, user authentication including single sign-on
4.2Withdrawal of agreementUser selection from DVB-I player UI.Used in combination with service list installation app. It enables user to withdraw agreement or consent given when that app was run
4.3Renew AgreementStarted by DVB-I player based on information provided when service list installation app exits.Used in combination with service list installation appIt enables service list provider to require users renew agreement or consent

With the release of HbbTV Core Specification 2.0.4, “Annex O” extends HbbTV’s functionality to hybrid scenarios (e.g. DVB-I). This annex provides the mechanisms for:

  • HbbTV application lifecycle
    • An application, if correctly signaled, can be kept running on services from different mediums (e.g. broadcast and broadband)
  • Hybrid channel List management
    • An application is able to access to the hybrid channel list created during installation process, allowing the user to select services from different mediums (e.g. broadcast and broadband) and broadcasters to implement smart fallback management to IP delivered content
  • DASH management
    • Reinforced requirements for playing live content and in-band events, which have the same functionality provided by DSMCC stream event on broadcast

The specification permits creation of a single HbbTV Application capable of running on both broadcast and broadband environments.

Where HbbTV is needed

In DVB-I ecosystem, it is important to manage as much functionalities as possible at the ‘native’ level within the consumer device. However, there are functionalities that devices are not in the position to manage at native level and require an application level implementation (e.g. HbbTV), these include:

  • Standardized technologies but with un-unique implementation
    • E.g. mABR: mABR client implementations are dependent on the network provider’s implementation.
  • Service-provider customizations
    • E.g. QoS Monitoring: There are different monitoring systems available which may require user agreement for GDPR compliance for tracking.
  • Technology provider customizations
    • E.g. DRM system: Different DRM systems provide different mechanisms, for instance there are different mechanism for license acquisition and authentication.
  • Client side ad insertion/substitution (CSAI/S)
    • This requires an application running on the device to perform the insertion or substitution. 

There are functionalities which can only be basically managed by the device at native level and can be enhanced at the application level, e.g. accessibility features.

Use Case Examples

Example use cases for HbbTV in an DVB-I environment include:

  • DRM Management: HbbTV applications can handle complex Digital Rights Management (DRM) systems, supporting different license acquisition methods based on service provider policies.
  • mABR (Multicast ABR): In collaboration with network providers (e.g. TIM in Italy), HbbTV can integrate third-party libraries to optimize ABR delivery, enhancing quality of service (QoS) over varying network conditions.
  • Hybrid Applications: interactive “red button” applications running in across both broadcast and broadband services.
  • CSAI/S (Client-Side Ad Insertion/Substiution): HbbTV applications can provide targeted, personalized ad experiences, leveraging real-time user data to enhance monetization.

Challenges and Considerations

While HbbTV offers extensive capabilities, it is not a complete substitute for native terminal functions. Key features like channel list creation, parental controls, and basic accessibility features are better handled at the native level for consistency and performance. Additionally, varying implementations of technologies like mABR and DRM across different service providers can still present interoperability challenges even when using HbbTV.

Conclusion

The collaboration between HbbTV and DVB-I is a critical step toward a fully hybrid TV ecosystem, blending the best of broadcast and broadband worlds. As standards continue to evolve, this synergy will likely play a pivotal role in shaping the future of television, enabling richer, more interactive viewing experiences. For broadcasters and service providers, investing in this integration means future-proofing their platforms to meet the diverse demands of consumers.

With ongoing advancements in HbbTV and DVB-I, the future of television promises to be more connected, interactive, and immersive than ever before.

DVB World 2025: The future of HbbTV and DVB-I in the media landscape

The DVB World 2025 conference, held in Munich on 18-19 March, brought together key stakeholders from the broadcasting and media industry to discuss the evolving landscape of television and streaming. Among the major topics of discussion were the DVB-I and HbbTV standards, which are set to play significant roles in shaping the future of media delivery.

DVB-I: Bridging broadcast and streaming

DVB-I was at the heart of many discussions at the conference, with industry leaders recognising its potential to combine traditional broadcasting with modern streaming. DVB Project Chair Remo Vogel (ARD/rbb) set the tone for the event by acknowledging that “streaming is becoming a candidate to replace broadcasting.” DVB-I has emerged as a crucial response to this shift, offering a seamless blend of broadcast and internet-delivered content, ensuring a more integrated and user-friendly viewing experience.

A notable development was the strong interest shown by a Chinese delegation in the DVB-I standard, indicating potential future adoption in the region.

HbbTV: Enhancing the viewing experience

HbbTV was another focal point, with HbbTV Chair Vincent Grivet predicting further convergence between TV and streaming services, stating that “the difference will not be between broadcasters and streaming services in future, but between local and global players.” HbbTV plays a crucial role in enhancing the hybrid experience by providing a familiar interface for users accessing broadcaster VOD (BVOD) services and interactive features offering an enhanced viewing experience.

HbbTV Chair Vincent Grivet

BVOD is experiencing remarkable growth, projected to increase from €4 billion in 2024 to €8 billion by 2029, reflecting a 15% annual growth rate, according to Ophélie Boucaud (Dataxis). This trend is vital for broadcasters, as their revenues are expected to remain stable or even increase thanks to a combination of public funding, advertising revenue, and the booming BVOD sector. In many European markets, BVOD services are powered by HbbTV, whether through the classic ‘red button’ functionality or more advanced implementations such as Freely, the UK’s new TV platform based on the HbbTV Operator Application.

The expanding DVB ecosystem

The conference also featured broader discussions on DVB technologies beyond DVB-I and HbbTV. Topics such as 5G Broadcast, satellite broadband, digital rights management (DRM), and energy efficiency were explored. One of the standout announcements was the commercial launch of the first smart TV supporting Sat.tv Connect, integrating DVB-I and HbbTV for a richer free-to-air satellite TV experience. Developed through a partnership between Eutelsat and Vestel, this smart TV eliminates the need for external set-top boxes and offers an advanced electronic programme guide (EPG) with a dynamic channel list.

A collaborative and interactive event

DVB World 2025 continued its tradition of being an interactive and collaborative platform. The unconference format, which allowed attendees to pitch and host their own sessions, led to engaging discussions on the future of DVB standards. Topics ranged from inter-SDO collaboration to volumetric video and the evolving role of the DVB Project itself.

Building the unconference agenda

The event also paid tribute to long-time DVB contributor David Wood, who was honoured with an award for his outstanding contributions to the project.
