Re: Waste of bandwidth without content

Could a 2 hour 4K movie even fit on a blu-ray disc?

I have seen Sony's new 4K BR player for sale in the B&H Photo Catalog. Quad layer BRD (BDXL) holds 128GB. I would guess that Bluray 4K would use BDXL discs. 4K may not even be "Bluray" since it is just called 4K in the description (unlike "3D Bluray"). Without content though it is little more than an upscaler at this point.

I was told that most new digital movies are "4K". If this is the case then the product is there the only issue will be how it is distributed. The question I have is if sports or the porn industry will jump start the technology. I understand that 3D with the 4K system actually works so that is another potential area of interest. As far as those who oppose this technology my first guess is that Apple would be in the front (or back) as they have tried to kill BluRay in the past. Those who see the future as product via cable or DSL may be surprised. I want a quality picture, not some grainy, blocky, over compressed image full of artifacts. The price will come down and more people will buy it. This could make a major dent in the projector market as you can have a large high quality picture in a room with "normal" lighting.

There were a handful of Blu-ray players from a few different companies (Sony, Oppo, Panasonic, etc) on display at CES with the ability to upscale to 4K but none of them had the capability to play 4K content off of disc.

There isn't any content to be put onto disc. But disc is where 4K content should start.

4K Can use any BR disk size but if you put it in the way a movie is intended to be put on a BR disk it will only be 1080p no matter what the disk size is.

The only way 4K will ever be on BR is as a data disk. Which you could do even on a DVD if you wanted to.

Playing it off a BR player will become a problem as bit rate goes up.

HEVC (Hi Efficiency Video Codec) will solve the bitrate issue.

storage size . needs to catch up and big thing with 4k is you need a tv larger then 42 inchs to really notice it

Would a 4K movie be fatter than 128GB? Just using a cheese download calculator if the stream is 51Mbps, 128GB would be 5.5 hours. At 100Mbps, 2 hours 50 minutes. Seems if the newest multilayer bluray discs were the media of choice that it could easily hold a 4K movie.

Not to me and certainly not with how usage caps are going in the US markets. Content will need to debut on hard media and then in 10-12 years when 4K sets are the norm and ISPs have caught up with throughput, Netflix will have the stuff.
