If you are a TV broadcaster struggling with the high cost of building interactive companion apps for each show or format — this project developed an open-source CMS with a backend and frontend that lets editorial staff create HbbTV applications without custom development. Over 90% of Connected TVs sold in many European markets already support HbbTV, meaning your interactive content reaches a massive installed base immediately.
WordPress-Style Toolkit That Lets Media Companies Build Interactive TV Apps Without Coding
Imagine you want to add interactive features to your TV broadcast — like letting viewers click to buy something, vote in a poll, or catch up on missed episodes — but building that from scratch costs a fortune. MPAT is basically a WordPress for interactive TV: a drag-and-drop content management system that lets editorial staff create and publish HbbTV apps without needing a developer for every single show. It works across smart TVs, tablets, and phones, and it's open-source so anyone can extend it with plugins. The consortium tested it through large-scale pilots with real broadcasters across Europe.
What needed solving
Creating interactive TV applications — things like catch-up TV, on-screen voting, or interactive ads — requires expensive custom development for every show or format. Most media companies simply cannot afford it, leaving their HbbTV-enabled audience underserved. There is no widely available, affordable CMS-style tool that lets non-technical editorial staff build and manage interactive TV content the way WordPress lets people build websites.
What was built
MPAT delivered a complete open-source content management system for interactive TV, including a CMS core backend, CMS core frontend, and extensible modules and plug-ins — each delivered first as trial-ready versions and then as final versions refined through large-scale pilot feedback. The platform enables semi-automatic authoring of customised HbbTV applications for multi-screen experiences.
Who needs this
Who can put this to work
If you are an advertising agency looking to deliver interactive TV ad experiences but find bespoke development too expensive per campaign — MPAT built a modular plug-in system where new interactive ad formats can be created once and reused across campaigns. The toolkit was validated through large-scale trials and supports HbbTV 2.0 with multi-screen synchronisation, letting viewers interact on their phones while watching TV.
If you are a CMS vendor or digital agency wanting to offer connected TV services but lack HbbTV expertise — MPAT delivered a complete CMS core with backend, frontend, and extensible modules and plug-ins, all open-source. The 8-partner consortium across 5 countries refined the platform through iterative trial feedback over 2 years, producing a production-tested toolkit you can white-label or build upon.
Quick answers
What does this cost to adopt?
MPAT is open-source, so the core platform itself is free to use and modify. Your costs would come from customisation, hosting, and integration with your existing content workflows. Since the project ended in 2017, there is no commercial support team — you would need in-house or contracted developers familiar with HbbTV and the MPAT codebase.
Can this scale to serve millions of TV viewers?
The platform was designed for broadcast-scale deployment — HbbTV apps are delivered alongside the TV signal to all compatible sets. Based on available project data, the consortium conducted large-scale trials validated through an exhaustive set of pilots. The CMS architecture supports linking to existing content management solutions, which helps handle high-volume editorial workflows.
What is the IP and licensing situation?
The MPAT core is open-source, which means you can use, modify, and distribute it freely under its open-source license. Individual plug-ins or themes developed by third parties may have separate licensing terms. Based on available project data, the business model was explicitly designed around an open ecosystem similar to WordPress.
How mature is the technology — is it ready for production?
The consortium delivered both trial-ready and final versions of the CMS backend, frontend, and plug-in modules, incorporating feedback from large-scale trials. This is an Innovation Action funded project that was explicitly described as a close-to-market solution. However, the project ended in 2017, so the codebase may need updates for current HbbTV standards.
Does this work with our existing broadcast infrastructure?
MPAT was built on the HbbTV standard, which is supported by over 90% of Connected TVs sold in many European markets. It supports HbbTV release 2.0 with HTML5, multi-screen services, and media synchronisation. The CMS can link to existing content management solutions, reducing the need to replace your current editorial tools.
Who built this and can we trust the technology?
The consortium was led by Fraunhofer, one of Europe's most respected applied research organisations, and included 8 partners across 5 countries with 3 industry players and 2 SMEs. The project delivered 32 deliverables over 2 years, including iteratively improved software based on real trial feedback.
Is this compliant with European broadcasting regulations?
HbbTV is the European standard for interactive TV, already mandated or widely adopted across EU markets. Based on available project data, the consortium included key players from the HbbTV domain who ensured the platform aligned with the standard's requirements including HbbTV release 2.0 specifications.
Who built it
The MPAT consortium was led by Fraunhofer (Germany), Europe's largest applied research organisation, lending strong technical credibility. The 8-partner team across 5 countries (DE, FI, FR, IT, UK) included 3 industry partners and 2 SMEs, giving the project a 38% industry ratio — a solid mix of research depth and market awareness. With 2 universities providing academic rigour and key players from the HbbTV and media domain, the consortium was well-positioned to build a production-ready toolkit. For a business considering this technology, the Fraunhofer name and the breadth of European media industry involvement signal that the platform was built with real-world deployment in mind, not just as a lab exercise.
