As expected, 4K / UHD was rejuvenated by the addition of High Dynamic Range (HDR) and a host of carefully crafted demos to show the latest crop of debutant screens, unveiled earlier at CES in all their glory. The results were certainly impressive, but needed considerable technical insight to unravel what was behind “the screen”…

Key Takeaways from CES 2014

While working off my Christmas pudding wandering around the various halls making up CES it occurred to me that branding was more evident at the show than technology.

What Happened at CES 2014?

Like many, I paid homage to Vegas for my regular post-Christmas tech binge. 4K and Ultra HD took center stage as expected, but unlike last year, the offerings were more tuned to a service, at least from an OTT, VOD and streaming perspective.
