extending the VPAID 2.0 Spec from IAB to support
Advanced Interactive ads which mostly live along
the player for the whole duration of the played item
and thus requiring a deeper participation of the main players'
state.

such VPAID ads might be analyzing the video feed prior
or in real-time, or simply do other manipulation while
the main item is playing.

the need for this has arrised as new 3rd party
companies provide advanced overlays over video
while VPAID at most can be a proper host for
such a technology.

as such, VPAID had to be minorly extended.
