RDK is a community-based project that enables developers, vendors, and cable operators to utilize a defined stack of software on one layer for provisioning set-top boxes and gateways. Unique features of RDK, such as its commitment to open source, the speed, and flexibility of RDK-based devices, set it apart from conventional set-top software stacks.
The standardized RDK‐V stack provides a common method for managing complex video and management functions, including rendering, content, content security, device management, networking, and peripherals.
The RDK‐V Feature List is categorized based on the following functions. Enhancements and new features are developed and contributed asynchronously by members of the RDK Community.

The device dependency in this context meant that the feature is only available in some OEM devices and not generally available in raspberry pi like reference devices. |
