Sony's upcoming 4K movie delivery service likely to work on the PS4

  1. Sony Electronics president and COO Phil Molyneux recently shed some more light on the notion that the PlayStation 4 will be able to support 4K ultra-high definition content. The executive said we will not be disappointed when asked if Sony’s...

    The real question is, does Sony's PS4 "support" of 4K mean it will view it but downscale it to 1080p, or will it actually be capable of outputting that native resolution to a 4K TV?

    Video might be possible, but I don't think there will be many games (if any) that could play at 4K. They just need the software to support it, the hardware already dose.

    Since the majority of internet in the US' internet is slow, this would be a fail

    This is very true. I was curious as to the size of 4K videos, and 100GB+ sounds about right. The good news is there are 100GB+ Bluray disks already. The bad news is streaming will be impossible without a new compression ratio (H.266 anyone?)

    Time to get my 76 Mbps Broadband then... and a small fortune for the TV. :D

    One improvement may require 3 improvements as well. With blurays, I never really though of it effecting internet speeds over the years. As for 1080P and smart tvs, this may have pushed faster internet

    I can't imagine downloading 100 gig files. Hell, I don't use 100 gig in a year. It's just way too expensive.

    I'm not so sure compression is going to be the answer, I'm think they are going to have to improve infrastructure.

    I feel like this will be a huge burden on the current infrastructure as said by Tekkraiden. I currently have unlimited 20mb/s download and 5 upload. If this gets to be too much of a burden, internet companies will begin to cap.

    Bring it on! I love to see a service that has astronomical requirements for bandwidth. How else would ISPs fall in line to provide higher bandwidth unless the average user has that same demand? TWC already said recently they didn't care to provide 1 Gbps internet because only a fraction of percent of their user base would actually subscribe to it.

    As for the technology, I'm surprised at the 100 GB file size for videos. OTA (over-the-air) signals are broadcast in MPEG-2 (H.262) resulting in files around 7 GB / hour for 1920x1080. With H.265 in final draft this year, we are seeing a 70% efficiency gain in the bit rate reduction compared to H.262. That means what was 7 GB could take up only GB. And since 4K is roughly 4x the resolution of 1080, then I would expect an hour of 4K video to be around 8.4 GB with H.265.

    Netflix was doing 1280x720 at around 5.23 Mbps, or about 2.3 GB per hour. 4K at that same compression would result in 20 GB.

    I know the math is not that easy but this should be a decent ballpark number. Maybe they were talking uncompressed?

    ... what was 7 GB could take up only 2.1 GB ...

    Somehow forgot the 2.1 in the original post.

    Actually I Was reading an article today about a breakthrough with graphene. How a terabyte of data can be transferred in a second with a graphene antenna. Very interesting. We just need HDDs and SSDs with the capacity to keep up with the bandwidth (also it will probably cost a fortune to embed these systems into a network. And graphene is rare as it is also.)
