Sofia Digital and Castlabs have integrated the DRMtoday multi-DRM service into the HbbTV application stack for Spain's LOVEStv platform. The deployment supports Widevine and PlayReady across 20 million devices, providing a scalable foundation for content protection and future Ultra HD delivery.
This deployment addresses the technical fragmentation inherent in hybrid broadcast broadband environments by unifying content protection across multiple hardware generations. By moving away from bespoke implementations toward a pre-integrated HbbTV stack, Spanish broadcasters can accelerate the rollout of advanced features like targeted advertising and 4K streaming without compromising security. The move signals a shift toward standardized, scalable security frameworks in the European HbbTV market, which has historically struggled with device interoperability. Watch for whether this unified DRM approach becomes the blueprint for other national HbbTV consortiums looking to modernize their catch-up services for the Ultra HD era.
Castlabs has been steadily expanding its DRMtoday footprint across European hybrid TV platforms. The company's multi-DRM service, which supports Widevine, PlayReady, and FairPlay from a single integration point, has become a common choice for broadcasters seeking to unify content protection across fragmented HbbTV device ecosystems. Sofia Digital and Castlabs announced the integration at IBC 2026, where the companies demonstrated the combined HbbTV stack targeting Spanish broadcasters' catch-up and start-over services. The deployment covers RTVE, Atresmedia, and Mediaset España, the three founding members of the LOVEStv consortium that launched in 2018 as Spain's unified HbbTV initiative.
The LOVEStv platform itself represents one of Europe's more ambitious national HbbTV efforts, combining broadcast and broadband delivery for Spain's major public and commercial broadcasters. The platform runs on Cellnex's broadcast infrastructure and reaches approximately 20 million unique hybrid TV devices. Sofia Digital, a Finnish software company specializing in HbbTV application development, has served as the primary application-layer partner for LOVEStv since the platform's early iterations. The addition of Castlabs' DRMtoday service marks a shift from earlier device-specific DRM implementations toward a cloud-based, multi-DRM orchestration layer that can adapt to new device generations without requiring per-device engineering.
In the broader European HbbTV market, multi-DRM integration remains a persistent challenge as broadcasters prepare for Ultra HD and next-generation codec transitions. The HbbTV Association has been working on updated specifications to support newer content protection requirements, and platforms in Germany, France, and Italy face similar interoperability hurdles. Castlabs' approach of abstracting DRM license acquisition through a cloud service rather than embedding device-specific DRM clients aligns with the direction the HbbTV specification has taken toward more flexible, server-driven security models. For LOVEStv specifically, the unified DRM layer positions the platform to support 4K HDR content delivery with appropriate rights management as Spanish broadcasters plan their Ultra HD roadmaps.
The LOVEStv HbbTV platform has integrated Castlabs’ DRMtoday service into its application stack, providing Widevine and PlayReady protection for 20 million hybrid TV devices. This deployment unifies content security for Spanish broadcasters, enabling the future rollout of Ultra HD content and advanced features while reducing the need for bespoke DRM projects.
The integration unifies content protection across 20 million hybrid TV devices, allowing Spanish broadcasters to secure catch-up and start-over services while preparing for future Ultra HD content delivery.
The LOVEStv consortium includes Spain's major public and commercial broadcasters: RTVE, Atresmedia, and Mediaset España.
By using a pre-integrated stack from Sofia Digital and Castlabs, broadcasters can move away from device-specific, bespoke DRM implementations, allowing for more scalable security and easier deployment of new features.
The integration utilizes Media Source Extensions and Encrypted Media Extensions (MSE-EME) to bridge legacy and modern HbbTV interfaces.
