The ins and outs of CNN’s HD ‘hologram’
Nov 11, 2008 1:53 PM
A still from a pre-election night test shows the quality that is possible with the ‘hologram’ system. CNN intentionally gave the actual use of the technology a blue glow and other effects to give viewers a visual cue that correspondent Jessica Yellin wasn’t actually in the Election Center studio.

For last Tuesday’s Election Night coverage, CNN featured what it called a “hologram” that brought a 3-D representation of correspondent Jessica Yellin into the network’s Election Center in New York City from a special remote studio set up in a tent in Chicago’s Grant Park.
Inside the tent were a green-screen set and 35 miniature HD cameras equidistantly placed in a 220-degree arc. At the heart of this TV magic was a Vizrt real-time graphics processing engine and a special plug-in from SportVU that picked up images from the appropriate miniature HD cameras and processed them to match the perspective of the studio cameras in New York.
This week, Vizrt director of usability, Nir Goshen, who was directly involved in the project, discusses what was required to bring this brainchild of CNN senior VP David Bohrman to life. This week’s Sound Off interview is presented as an audio podcast.
