Ad units are a special section in Brid which don't require any video content at all.
They are in fact a stripped down Brid player with special options that provide specific advertising and monetization solutions to publishers.
Currently, Brid supports a single ad unit that we call an outstream unit which can behave in a couple of ways:
The in-content outstream unit is made to appear inside your content if an available ad exists while the in-slide unit will slide in from a corner of your site the moment an ad is available.
The in-video unit behaves the same as the in-content unit only it has an option to fallback to a 300x250 banner code if no pre-roll is available for display.
