NBC mentioned it would deliver two complementary mobile apps for its extensive London Olympics coverage and now they have arrived. Available for Android phones and tablets as well as the iPhone and iPad, they're built on Adobe technology to deliver the information and live streaming video, as well as handle the TV Everywhere authentication with the cable providers that's necessary to view all of the content. The NBC Olympics Live Companion is specifically designed to operate as a second screen for users to pull up stats and extra info on while they watch TV, and the NBC Olympics Live Extra app delivers video of every event streaming live to users wherever they are. It supports multiple camera angles, social features like the Facebook tie-ins NBC announced yesterday and users can even switch between the two apps at will.

Check after the break for a quick video preview of some of the technology at work, and if you're planning to tune into the games, hit NBC's Olympics site now to sign in and authenticate so once the Opening Ceremony kicks off, all you'll have to do is press play.
