Uncompressed streaming

[robfosters]

I’m just curious as to what internet speed is required for uncompressed 4K HDR 60Hz streaming?

How long are we looking at before it becomes available with all the audio bells and whistles too. I hear so much about manufacturers ceasing production of blu ray players that it makes me think they are expecting it before long.

I imagine any streaming service offering lossless streaming will be priced at a premium

Sony Bravia Core iirc.

Min 100Mb recommended I would have thought as that's about the bitrate peak of 4k BR.

Actual true uncompressed at that resolution and frame rate would be near 30Gbps so you won't be getting that at home ever lol.

So a 4K blu ray is still compressed, just at a much higher bitrate?

Yeah of course its compressed from the master.

100Mb is enough to resolve most of the details for TV use though. Only pickiest bunch would notice.

Yep - 4k Blu-ray is around 100Mbps, Vs the likes of netflix 4k that is 16Mbps

All of Netflix’s HDR video streaming is now dynamically optimized

Also compressed doesn’t necessarily mean lossy. You can have lossless compression, sent in a compressed format and the decompressed locally, required a beefier processor on your end. But you get lossless quality.

Yeah, most of the higher end ones max out at around 80-100mbps but you do get the odd ones that go above 100.

You need to be fairly careful about terminology.
Pretty much all normally available digital video uses compression, and it’s lossy. Note that this is the video part, NOT the audio, which is available in compressed by lossless format.

14.4 k dial up

That point at which even lossy compression becomes largely indistinguishable to the naked eye is far lower bitrate than uncompressed 4K - IIRC about 56mbit/s for 4K60.

No point making new spinners if there is zero new tech to be added.

I'm still using my UB900 from 2016. Sure some new tech has come along since, but to make the most of it I'd have to upgrade my 2016 AVR as well. Don't watch enough tv these days to warrant that unless one dies.

I directly rip my blurays and UHD to my Synology, no compression beyond whatever is on the disc.

I found that a 100Mbps NIC is not quite enough for UHD, stream is just over.

I'd be more bothered about getting the Audio Codecs expanded beyond E-AC3 as long as the Video element has a decent bitrate, TrueHD with Atmos would be the sweet spot for me.

DTS:X is finally coming to Disney around May/June time.

That's good to hear, very few films are available in lossless DTS:X, but I often prefer it to Dolby Atmos for object placement in my home theatre.
