None of these links are related the conversation here. First one is even empty. Neither for "video streaming", nor for frame-buffer (Optimus) stuff.

Now you want streaming to mean something that is used in game engines. How those 3 links help in making the mining card usable is for you to proof.
That's exactly what streaming means as a technical term:
