RDK is a community-based project that allows developers, vendors and cable operators to use a defined stack of software on one layer in order to provision set-top boxes and gateways. Unique features of RDK such as commitment to open source, speed and flexibility of RDK-based devices makes it stand out from the conventional settop software stacks.

The RDK‐V standardized stack provides a common method to manage complex video and management functions such as rendering, content, content security, device management, networking, & peripherals. 

The RDK‐V Feature List is categorized by the below functions, Enhancements and new features are developed and contributed asynchronously by members of the RDK Community.
