4K Ready needs a bit of clarification :

4K @ 60p or 4K @ 24p?
H264/AVC 4K or H265/HEVC 4K?
Displayport 1.2 or HDMI 2.0? (Or is HDMI 1.4 OK for you?)

4K HEVC on CPU is pretty brutal. I can pull it off on a 3770K but that's not what most people put in their HTPCs. That said, I think I can manage it with only three cores on... But still.

Best wait for GPU based support to get more out there.

Though the biggest hurdle, really, is a definitive SOURCE for 4K material to watch.

Can i add, gpu later on to my setup?

happy2 · 2014-10-01, 10:15

and does it even matter, to build a 4k ready system, at the moment?

Or what do you think?

And does my setup, look ok so far?

If your case can host a PCI-E graphics card, then you could upgrade to add a GPU with HEVC 4K support. It'll probably be a year or two till such offerings are available, but the acceleration should be featured even on low end GPUs when it comes around, so a small, low end GPU offering HEVC.4K would do the job and you could install it when the time comes.

But like I said before, there's a real lack of sources of 4K content. Netflix only seems to give it to select Smart TVs, of which I've never seen get ripped, There's no 4K optical media. There seem to be no other major 4K streaming services. If you go on torrent sites and look up '4K' you get two major results: Sony 'Remastered in 4K' bluray rips, which are still 1080p, and 4K porn. Yes, porn is on the cutting edge of using 4K as a release format.

So 4K isn't going to be a concern till there's a way to GET 4K outside of the occasional indie film or other release online.

There have been some 4K HEVC trial DVB-T2/DVB-S2 broadcasts in Europe (we got 3 World Cup matches and the Commonwealth Games in 2160/60p and 2160/50p respectively on the BBC trial service over the summer) but you are right there is a scarcity of 4K HEVC content at the moment.

Is this even actually 'available'? I went looking and I can't find any torrents of the world cup at 4k. I can find torrents of high def games but none in 4K. Was this 4K broadcast even put through any system that could be decoded by anything other than a real TV box?

I recorded all the matches off-air and they were standard DVB-T2 with a video stream flagged as HEVC, broadcast on the frequency allocated to COM8 (the yet-to-launch 3rd DVB-T2 mux in the UK). The mux was running at the UK standard 40.25Mbs (256QAM 32k carriers) and ran at around 37Mbs for the video bitrate. (The audio was stereo AAC)

DVB Viewer happily received and recorded them. I don't have a 4K setup to watch them - but was able to view them in ffplay cropped to 1920x1080 on an i7-2600K over clocked to 4GHz with just a few dropped frames (using an Open HEVC branch of ffmpeg) Scaling to 1920x1080 was a bit more work and caused more dropped frames.

I stand corrected, though confused why I couldn't readily dig up 4K torrents of the games, just cause I'd have thought there'd be some demand and all that.

Though still, yeah, 4K sources are few and far between. We'll really see things change once at least one mainstream source for 4K turns up.

Suspect there weren't that many of us recording the DVB-T2 stuff - and the files were pretty huge. Won't comment on sharing content with significant rights issues...

'Well, I'm not trying to discuses the rights thing. More like 'Wow, you'd think pirates would be totes ontop of 4K rips of The World Cup.' Using it as a metric of the pervasiveness of 4K and nothing else.
