Overview 


We are excited to introduce RDK7, the first release of the newly restructured RDK stack that features a modular, three-layered design. This architectural enhancement represents a foundational shift aimed at improving development agility, portability, security, and ecosystem scalability.

This release includes the initial implementations of:

  • Vendor Hardware Abstraction Layer (HAL): Clean interface to hardware drivers and chipset integrations
  • Core RDK Layer: Refactored middleware and services, optimized for stability and performance
  • Application Layer: Isolated app runtime supporting independent development and deployment

This modular design empowers independent development and testing across layers, streamlines integration across multiple hardware platforms, and enables faster innovation cycles.


Please review the detailed change logs and migration guidelines included below. We welcome community feedback as we continue to evolve the stack in alignment with open standards and industry needs

RDK7 is the newest open source software release, supporting both IP and Hybrid video platforms. It integrates over-the-top (OTT) video apps through the FireboltTM framework, standardizing interfaces for video playback, digital rights management (DRM), graphics, and security. RDK6 builds upon previous RDK releases to further simplify app development, enhance security, and standardize functionality across diverse set-top box hardware.

Key capabilities and benefits of RDK6 include:
  • Support for various DRM solutions, video security integrations, and the WebKit browser
  • Improved efficiency of video app integration and core video functionality management across chipsets and device manufacturers
  • An updated certification suite to ensure consistency and performance of your devices
  • Device-agnostic downloadable application containers for native video apps and AppArmor-based access control
  • Containerized browser instances for LightningTM or HTML5 streaming apps
    • Unified Application Interface with Firebolt

    Key features of RDK6:

  • Pre-certified apps package - includes pre-installed apps such as YouTube, Amazon Prime, and Alexa
  • Voice search and pre-integrated voice remotes  
  • Updated RDK Reference UI - Lightning-based interface for RDK Reference devices and video accelerators
  • Firebolt - Standardized specification for integrating Native and web applications
  • Unified player interface for IP, OTT, and hybrid devices
  • Security enhancement using app sandboxing (Containerization)  and access control (AppArmor)
    • Device management using firmware upgrade, Telemetry, WebPA

    Architecture Overview: StatuscolourGreentitleDONE 

    A quick architecture overview of RDK7, to help associate the capabilities with the software stack, is given below

    Build system Overview: StatuscolourGreentitleDONE 


    Compared to previous releases, RDK7 follows a layered build approach. The build setup is now divided into a set of independent Stack layer projects, each comprising components that are developed separately and delivered as binary packages(ipk). These stack layers are then assembled into the final image using the Image Assembler tool. The build setup maintains a Reference OSS layer, which serves as a reference Yocto distribution layer( which also includes CVE patches ), a vendor layer that contains the vendor specific code, an RDK middleware layer that contains the core RDK middleware components, and finally an application layer that contains the applications.Image Removed

    The build system introduced in RDK7 is comprehensively covered in the technical session held during the RDK Tech Summit in May 2025

    Note

    The session video linked below provides a technical overview of the layered build architecture designed for comprehensive RDK-E builds. This architecture is intended for future RDK releases and does not directly correspond to the current RDK7 release. The video is included as a supplementary technical resource to aid understanding of the build process.
