8K discussion thread

I'm pretty sure with the samsung q900r 8k is somewhat future proof, all you have to do is replace the One Connect Box if any new HDMI spec comes out. Like for those who bought 8k model last year Samsung gave them free upgrades to the One Connect Boxes with the current specs.

What’s the spec difference between last year’s One Connect and this year’s? I didn’t knwo that Samsung released any 8K last year.

Samsung's One Connect serves more as a place to route cables away from the wall mounted display then anything future proof. If anything it resembles a laptops port replicator such as the problematic Thunderbolt 3 Docks they have out there. They are selling TV's like computer displays. But the Tizen environment, apps, processor/memory will still be old come couple of years from now, so the One Connect Box can't fix that.

The video processors etc are inside the One Connect, no?

NEC Demos Live 8K Video Transmission Over 5G

Wondering how we will ever enjoy watching live television in beautiful 8K resolution?
The answer was delivered in all of its glory at the recent French Grand Slam Tennis Tournament using high-bandwidth 5G wireless broadband technology.

Japan’s communications giant NEC Corp. said this this week that it successfully transmitted live 8K video of the French tournament at Roland-Garros in cooperation with France Télévisions, France’s largest public television station, according to a report Tuesday on international video business trade site Advanced-Television.com.

The transmission utilized NEC’s VC-8900 8K transmission encoder, running real-time video compression technologies, to transmit live 8K video of the tournament to 8K video monitors and 5G smartphones and tablets positioned inside the tournament grounds.

Well in Aug 2018 it was described as:

One Connect box is the media receiver with a built-in TV tuner used to support the Samsung UHD model's "One Connect" function. It minimizes cable clutter by functioning as a hub for connecting audio-video components, while using a single cord to interface with the panel. One Connect box provides seamless connection to various devices via RF cable, IR out, HDMI, Audio out, Component and Composite, Wired Ethernet, Optical audio out, USB etc.

Going by that I tend to doubt the video processing is taking place in it, more it just a smart hub to outsource the I/O from the display unit.

The thing is that one connect is huge, very heavy, and runs really hot. Samsung claims the processors etc are inside the One Connect, but I never opened one.

PS: There are two versions of one connect box. One version is light and does not turn warm at all. The ones used by the Q90 and Q 900 are the gigantic ones

I believe the video and audio processing are done in the One Connect box, but JohnAV has put a some doubt on my understanding. Maybe someone who knows can add to this discussion.

Even looking at several posts it doesn’t say definitively that all the processing is done in the larger one. But it does look like the Tizen OS runs completely now in the 2018/2019 larger one connect box as Sapiendut says. For example a octal core processor. So it’s possible?

[sapiendut]

Considering how tall and wide it is, I don’t think it’s even possible that it’s only a switcher. Plus considering the weight and heat emanating from that thing.

Oh I saw that after reading your previous comment. The part I was curious about is what the cable is supplying.

See Samsung's One Invisible Connection: 75 Gbps and 230W in a Ultra Thin Cable - Anandtech

Samsung’s One Invisible Connection, in turn, aims to simplify everything. In one small cable they are able to power a full-sized 4K display (up to 230W) as well as transmit 4K video (75 Gbps).

So that begs the question was has changed for the Samsung 8K?

[sapiendut]

Yeah that cable is mysterious. I still wonder how they transfer that much power through a canle that small. And the most annoying part? The cable is not fire rated. So you legally can’t put it in the wall

The original 85” or whatever was released didn’t have the proper I/O and wasn’t certified with the current 2019 spec. Earlier this year Samsung said they will replace those the first wave for 8K

[sapiendut]

But they didn’t have an 8K TV in 2018 at least not in Canada. Furthermore, even today’s Q900 doesn’t have HDMI 2.1 input either. Thus I still don’t understand what change was made.

Why you shouldn't buy an 8K TV in 2019

Some TV makers have already introduced 8K TVs, while others will join the race later this year. But there are lots of reasons why you shouldn’t buy an 8K TV this year. Allow us to explain.

As long as the TVs can’t do the full 48 gbps HdMI 2.1 and HFR I’m not buying.

I have mentioned this issue before that a 8K display needs a minimum of HDMI 2.1 in order to connect a future 8K external source at frame rates above 24fps (when external 8K sources actually exist for consumers). On top of that issue Hollywood around the year 2026 might decide to use a new version of HDCP to protect their 8K movie sources (unless they stay with HDCP 2.2 or 2.3 a new display will need to be purchased to get a 8K signal into the display).




select quote from article:

"The sad reality is that once again certain TV makers have been so eager to introduce 8K TVs that they have forgotten to include HDMI 2.1 ports to make possible 8K input. It is true that HDMI 2.0 can transfer 8K at 24fps (such as Hollywood movies) but without HDMI 2.1 you will be out of luck when it comes to most other types of 8K sources, including PCs, game consoles, streaming players and set-top boxes."

Other than Samsung who has an easy upgrade path to HDMI 2.1 with the One Connect box, who forgot to included HDMI 2.1 on their 8K TVs?

It's not Sony, LG or Sharp.

[sapiendut]

AFAIK, the HDMI 2.1 on any of the current TVs are not of the 48 gbps variety as reportedly there is no such chipset yet.

Full spec HDMI 2.1? That can be a gotcha.



And where's the content? Answer: There isn't going to be much of anything for years to come.

To sound like a broken record, there isn't a lot of true 4k content as it is and HDR mastering is all over the place.


4k should have been ironed out first.
