Issues with Glasses based 3D today
•  Need for glasses : Inconvenience, discomfort & cost issues to consumers
•  Consumer dissatisfaction with current 3D video quality
•  Consumer discomfort due to misalignment & changes in depth based on a per-display type –
Nausea & watchability/user-experience (lack of)
•  Consumers do not have the ability to customize the 3D portion of viewing experience
•  Bandwidth & infrastructure change required to upgrade to Full HD 3D (OTT & Broadcast)
Issues with Glasses-free (naked eye) 3D today
•  Limited “sweet spots” for viewing positions on AS3D (autostereoscopic) displays creates yet
another bad consumer experience
•  Issues with complex scenes on AS3D (autostereoscopic) displays is anticipated to generate
further customer dissatisfaction

Dolby 3D: What the Industry is Saying
“Even more impressive was the Dolby Labs and Phillips demo of Dolby 3D.
Embodied in a 4k 54 inch display, the demo delivered bright, clear and
detailed moving images. Very watchable!’

“Viewing angles were particularly impressive: even from far off to the side, the
3D effect was still present, and the picture was so crisp and clean that it almost
took a minute to realize we were looking at 3D footage…it's among the first
TVs we'd want to gather around with our friends and watch a movie in
3D.”

“Dolby has a glasses-free 3D display in its booth, and it is drawing big
crowds. The display was co-developed by Dolby and Philips, and Dolby is
showing some gorgeous 3D content to demonstrate the technology.”

“… the prototype 4K 3D TV and mobile versions being demonstrated at
Dolby's NAB booth make us hopeful for the future. As with all displays --
especially those that support 3D -- you'll really need to see to believe, but we
had an opportunity to do just that, and walked away very impressed.”

“...it was very impressive, and the 3D effect was quite apparent. In fact, it
was the best autostereoscopic display I've ever seen.”
