3D TV, HTML5, video over Wi-Fi, superfast USB, and mobile "augmented reality" will emerge as breakthrough technologies in the next few years. Here's a preview of what they do and how they work.

While sipping a cup of organically farmed, artisan-brewed tea, I tap on my gigabit-wireless-connected tablet, to pull up a 3D movie on the razor-thin HDTV hanging on the wall. A media server streams the film via a superspeedy USB connection to a wireless HD transmitter, which then beams it to the TV.
That actor--who was he? My augmented-reality contact lenses pick up the unique eye motion I make when I have a query, which I then enter on a virtual keyboard that appears in the space in front of me. Suddenly my field of vision is covered with a Web page showing a list of the actor's movies, along with some embedded video clips.
These technologies will come to life in the distant future, right? Future, yes. Distant, no.
Speed and content (much of it video) will be paired consistently across mobile, laptop, desktop, and home-entertainment systems. New ways of using video--including adding 3D depth or artificial visual overlays--will require more speed, storage, and computational power.
In our preview of technologies that are well on their way to reality, we look at the connective tissue of USB 3.0, 802.11ac, and 802.11ad for moving media--especially video--faster; at HTML5 for displaying video and content of all kinds consistently across all our devices; at augmented reality to see how the digital world will stretch into our physical reality by overlaying what we see with graphics and text; and at 3D TV, which will add image depth and believability to the experience of watching TV.
