I saw HD like this at the last NAB show in Vegas. It's geared for theme parks and special attractions. It's very cool, but for us mere mortals it has no use. We'll probably never even see full 1080p broadcast anytime soon...or ever.
"Ultra HD will have a whopping 7,680-pixel horizontal resolution by 4,320-pixel vertical resolution."
"And uncompressed Ultra HD files are enormous. The video is recorded at 24 gigabits per second, compared to 1.5 for standard HDTV. The hard drives used to store the data weigh 600 pounds, and 18 minutes of video requires 3.5 terabytes of space."
