4K resolution hardware will officially be called ultra HD

The Consumer Electronics Association (CEA) has announced the official name for the next generation 4K high-definition display technology: "Ultra High-Definition" or "Ultra HD." According to the CEA, the name is intended to infer the new format's superiority over conventional HDTV.

The CEA Board of Industry Leaders voted unanimously this week to recommend the previously mentioned names for the new next-generation HD resolution. Along with agreeing on a name, the CEA also outlined minimal performance characteristics to help consumers and retailers understand the benefit of the new technology set to begin rolling out this fall.

“Ultra HD is the next natural step forward in display technologies, offering consumers an incredibly immersive viewing experience with outstanding new levels of picture quality,” said Gary Shapiro, president and CEO, CEA. “This new terminology and the recommended attributes will help consumers navigate the marketplace to find the TV that best meets their needs.”

The core characteristics that the CEA agreed on include a minimum display resolution of at least 8 million active pixels with at least 3840 pixels horizontal and at least 2160 vertical pixels.

To meet the minimum needs the display will have to have an aspect ratio of at least 16 x 9. Devices meeting the specifications will also be required to have at least one digital input capable of carrying and presenting native 4K format video at 3840 x 2160 resolution without relying on upconverting.

The Blu-ray spec is that the video imagery is capped at 40 Mbps with audio capped at 8 Mbps.

The average over a movie with high action sequences (think of things like the recent Avengers movie) in 1080p is likely to be < 20 Mbps (honestly, I haven't checked). However, high action sequences with lots and lots happening in each frame will usually smack up against that 40 Mbps limit for several seconds. For these kinds of movies the post production guys generating the Blu-ray versions spend a lot of time to live within that cap and still have no apparent blocking of the imagery.

If they implement H.265 rather than H.264 and go to this "4K" Ultra HD standard (as different from the Digital Cinema 4K standard) then they'll still need double the bandwidth (H.265 proponents claim that H.265 requires half the bandwidth, on average, as H.264).

Therefore in order for the "next generation of Blu-ray" [or whatever they end up calling it] will need a video bandwidth cap of at least 80 Mbps with a total storage of 100 GB. If they don't go with H.265 but stay with H.264, you need to double that -- 160 Mbps for video and 200 GB for the disc size.

And just so you know, there have been 200 GB working units in labs for over four years and 1 TB versions working units in the labs for almost as long. They just haven't become commercialized because there really was no consumer need for them.

And to just stop any lingering arguments before they start... No, your satellite or cable provider does not deliver Blu-ray quality imagery. The imagery they provide is much more highly compressed. And yes, some people will claim they cannot tell the difference, but that is a personal level thing. It is not that there is no difference or that many people cannot tell the difference.

There are blu-ray recordable discs with 100GB and 128GB avalible right now with 3 & 4 layers.

The question is will those be used as the new standard for the next generation video players for the home or will there be something else.
