PIP: Picture In Picture
DTRT: Do The Right Thing
ISTM: It Seems That Maybe (guessed!)
IOMMU: Input/Output Memory Management Unit (guessed!)
video sink: a "target" which consumes video data (opposed to: video
source, a "thing" which creates video data)

As I understand the topic: he thinks about something like v4l/v4l2, but
better (and more generic which maybe can be named video4unix...).
The interaction with the device nodes is part of the userland.
