What's an ultraviolet™?
I would guess it's this:
UltraViolet (UV) is a digital rights authentication and cloud-based licensing system that allows users of digital home entertainment content to stream and download purchased content to multiple platforms and devices. UltraViolet adheres to a "buy once, play anywhere" approach that allows users to store digital proof-of-purchases under one account to enable playback of content that is platform- and point-of-sale-agnostic.
So... y'know, it's... that. Thingy.
