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 and speed and flexibility of RDK-based devices makes it stand out from the conventional software stacks.
The main features of RDK-V are categorized as:

MSE is a browser extension for doing programmable video, such that the video protocol can be decrypted and provide to the device’s codec; EME is how the media pipeline gets established underneath. EME uses CDMs, or Content Decrypt Modules, to implement the security mechanisms -- typically digital rights management (DRM), so, the work of it is largely key exchanges.
