Common Interface Plus (CI+) is an enhanced security standard that enables TVs and set‑top boxes to access encrypted pay‑TV services using removable Conditional Access Modules (CAMs). It delivers stronger content protection and improved interoperability compared to the original CI standard, giving broadcasters greater confidence when offering premium channels.
DTVKit’s CI+ stack supports both CI+ 2.0 USB CAMs and legacy CI+ 1.4 PCMCIA CAMs, ensuring broad compatibility across new and existing devices. Platforms that implement Enhanced Content Protection can securely access premium UHD content, meeting the latest operator and studio requirements.
Highly portable and easy to integrate, the stack works seamlessly with major DVB solutions, including DTVKit’s DVBCore and supports CI+ browser engines such as MHEG and HbbTV, enabling rich CAM‑based operator applications.
The CI Plus framework builds upon the core foundations of DTVKit’s DVB, ensuring seamless integration and compatibility across various platforms.
The CI Plus framework is built on top of DTVKit’s core DVB components, ensuring seamless integration and broad platform compatibility including RTOS, Linux, Android and RDK based platforms. Its flexible architecture supports deployment on systems both with and without a Trusted Execution Environment (TEE). Well‑defined interfaces enable smooth integration with either DTVKit or third‑party DVB stacks, as well as with MHEG and HbbTV engines to provide full CI+ Browser support.
As a member of the DTVKit community, we’ve benefited greatly from the collaborative environment and extensive support network. Using DTVKit protocol stack covering DVB/ATSC/ISDB and its complete suite of television service middleware services, we’ve been able to overcome numerous challenges.

Yes. The stack is continuously maintained and improved, with updates driven by:
evolving DVB, ATSC, and HbbTV standards
security and performance enhancements
real product feedback from active members
Every improvement strengthens the entire community and you benefit from the collective momentum.
DTVKit is designed to be flexible. It already supports Android TV, RDK, and hybrid white‑label platforms, and can be ported to Linux or other embedded systems.
Members choose DTVKit because it adapts to their roadmap, not the other way around.
No. DTVKit is fully independent.
We align with DVB and ATSC standards to ensure compliance and interoperability, but you don’t need to join those organisations to use our software. Membership with DTVKit alone gives you everything you need to build compliant broadcast products.
