CI Plus

Secure and Flexible
Content Protection

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.

CI Plus Features

  • Universal Compatibility: Supports both CI+ 1.4 (PCMCIA) and CI+ 2.0 (USB) CAMs for maximum flexibility.
  • Enhanced Content Protection (ECP): Delivers robust security required for premium UHD and protected broadcast services.
  • Flexible Architecture: Operates on platforms with or without a Trusted Execution Environment, ensuring broad deployment options.
  • CI+ Browser Support: Enables MHEG-5 and HbbTV CI+ based applications on the host device to enhance interactive TV services.

How quickly can I get started once I join?

Once your membership is confirmed and onboarding is complete, you’ll receive immediate access to the full DTVKit source code repository and documentation. Members are usually up and running within a few days.

How is the software licensed?

Membership gives you unlimited, royalty-free access to the entire codebase. Use it, modify it, ship it – without per-unit fees or runtime charges. This model keeps costs predictable and empowers you to innovate freely, without commercial restrictions holding you back.

Is the software updated regularly?

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.

What platforms does DTVKit support?

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.

Do I need to be a DVB or ATSC member to use DTVKit?

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.
