Ultra HD Blu-ray spec completed

The Blu-ray Disc Association has completed an Ultra HD Blu-ray technical specification that will lead to the release of players and discs that support the new format. Manufacturers will be able to license Ultra HD Blu-Ray beginning in July and, presumably, consumer products will begin to roll out later in the year.

The format supports Ultra HD 4K TV resolution (3840x2160), as well as enables high dynamic range (HDR), high frame rates and object-based immersive sound. HDR—a wider range between the whitest whites and blackest blacks—could either be delivered using the BDA-developed “BD HDR” portion of the new spec or by using certain supported HDR formats such as Dolby Vision.

Between this and 4K steaming creeping along maybe will start to see more content soon.

It's taking too long....they are dragging their feet. Maybe in another 5 years 4K will be omnipresent.

I do remember 1080p taking a long time to get to the market as well....I guess they wanted to milk 720 as much as they could. My phone/tablet has better resolution then my TV and PC.

I'd really love a 4K monitor and 4K TV but they don't seem ready for prime time yet.
 
Great...4x the information at the minimum and barely 2x the disc capacity. They need to do better than that.

Looks like I'm waiting for a PS4 Slim for the off chance it includes this.

I hope they upgrade the current model. There's no technical reason why it wouldn't be able to handle 4K video. Especially once HEVC gets GPU decoding. Remember that HDMI 1.4 can still do 4K at 30hz, which is what the vast majority of content is shot at.

The GPU in the PS4 doesn't have a HEVC decoder. The GPU needs extra stuff to decode HEVC, its not like the Ps3 where you could just throw SPUs at the problem.

60fps 10 bit HEVC? We will need MUCH MUCH better decoders than we have. That would eat a CPU alive.

Yuuup. I have some files that are encoded like that (I think, not positive), and the core i5-4200U just can't swing it. Tons of dropped frames and all that. 3570k with a proper video card can, but still. ouch.

HEVC theoretically gives you 2x encoding efficiency, too. Realistically you're looking at about 4x the data in 3.5x the space.
 
I just wish redbox would spit out a thumb drive instead of a disc. Even if you have to put down a deposit, big whoop. Discs are so 20th century. Ultra blu ray is like a souped up horsedrawn carriage.
 
Shame that there is still no talks about HDMI 2.0. I understand 1.4 can do it at 30hz and all that good stuff, but wouldn't it be great to have some extra band width to handle something better? Specially when we are talking about new standards...
 
Wonder if the players will be as buggy as the original BD players were for the first 4-5 years on the market. No thanks.

I don't want to get into the compression argument. Let's just say I'd prefer an option for an uncompressed source. 😀

Ignoring the new compression schemes for a moment, it seems like you are talking about two different things...the capacity of the disc and the size of the movie.

Right now, your average BD movie w/audio track(s) take up less than the full capacity of BD disc. Many movies, if they had no extras, would fit on a 25GB BD disc. So, even if 4K movies were 4x the size (which they won't be) they could still fit on a Ultra HD BD disc.

But, if you want to wait for something better to come along, more power to you.
