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:

• RDK-V Basic Features
• RDK-V Unique/ Upcoming Features
• RDK-V Features for RDK licensees

RDK-V Basic Features

RDK-V Unique/ Upcoming Features

WPE Browser with EME/CDMi

The feature list for the RDK-V browser is aggressive, starting with an MPEG-DASH and HLS player, Wayland support, switching to WPE, and moving RDK-V components like webRTC and CDMI into WPE.

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. 

<TODO: Add More Details>

Wayland/ Westeros

• Westeros is a simple light-weight, opensource Wayland compositor designed to be suitable for embedded systems. It supports normal, nested, and embedded wayland compositing. A normal compositor displays its composited output to the screen, while a nested compositor sends its composited output to another compositor as a client surface.
• Can be ported onto new platform by implementing westeros-soc which provides westeros-gl using EGL/GLES support and westeros-sink using hardware acceleration.
• Westeros-gl should provide native window support. While westeros-sink should provide video renderer on that platform.
• Westeros_test is a sample application for validating the compositor
• Component: Westeros

Ad Insertion (LSA)

• Settop support switching between QAM content and IP advertisements so that client side targeted advertising can be deployed.
• Settop switches from QAM content to MPEG2TS IP advertisement at specified point and vice-versa.
• Component section : LSA Architecture Design and Implementation

Audio Capture (Song ID)

• Implements method to capture audio clip from PCM output in order to support Music ID feature
• Capture data at settop and to transfer captured data to server.
• Component: audiocapturemgr
