Windows Display Driver Model (WDDM, [1] initially LDDM as Longhorn Display Driver Model and then WVDDM in times of Windows Vista) is the graphic driver architecture for video card drivers running Microsoft Windows versions beginning with Windows Vista.
Unified Video Decoder (UVD, previously called Universal Video Decoder) is the name given to AMD's dedicated video decoding ASIC. There are multiple versions implementing a multitude of video codecs, such as H.264 and VC-1. UVD was introduced with the Radeon HD 2000 Series and is integrated into some of AMD's GPUs and APUs.
This can reduce the input lag associated with v-sync. This is limited to DirectX 9, 10, and 12. [12] AMD Link allows users to stream content to mobile devices, compatible Smart TVs, [b] and other PCs with Radeon video cards, enabling them to use their PC and game on them remotely. It can be used both locally as well as over the internet.
