4K Video is Coming: Are Operators Ready?
Although 4K video is coming faster than many expected and the first UHD TVs are already in the stores, cable operators and other pay-TV providers may not be ready to support it.
That's because it takes much more computational power to deliver 4K video streams. As this infographic from QuickFire Networks shows, it will take 80 times more processing power to deliver UHD-quality video.
Or, put another way, it will take 20 conventional video servers to deliver a single UHD video stream.
