BBC World Cup in 4K/HLG Announced

I know what you mean, didn't seem quite a leap. Although, I work with 4K and even moving onto 8K footage at work so I'm a bit spoiled with it all now. And of course recorded footage is way higher quality bitrate wise than broadcast rubbish
Ha yes bitrate gets overlooked a lot and gets chopped pretty good by he time it makes it way to the home. There are some HD cable channels I had where the bitrate was so bad that it become unwatchable in some scenes(fast action in low light).
I've seen fantastic quality from even 480 if the bitrate was high enough
Exactly, a camera recording in 1080 can look very nice indeed with a decent bitrate, plus if helps in post processing. Broadcast is pretty low anyway, but it can be a complicated mixture of bitrates with streaming.
Overall the capture at site through the transmission system to the tv in the living room is pretty good. In the uk at least. Be it streamed or aerial. For 1080i anyway. Technology moves on and there are more efficient coders and software than a few years ago.
Some capture from premiere grounds is now uncompressed. Think about it.
Edit. UHD also has some interesting kit coming into use. I would not write off broadcast as the poor relation.

I’ve watched a couple of the matches in UHD and they look really good. Despite there being an apparent user limit, I was able to start watching the England match at halftime, and joined some other matches part-way through.
The one problem though is they are delayed compared to broadcast by something like 90 seconds, which is a potential problem. Virgin Media is slightly delayed by only a second or two compared to broadcast, but I can hear the neighbours cheering before I see the goal go in. Luckily I don’t hear the neighbours where my UHD TV is.

Initially I was miffed at this but reading is education so to speak and learnt a lot more since OP post 1. HLG test as per OP in post 1.
Guessing they want to test the delivery of HLG not 4k. I cannot do HLG (a type of HDR) and also excluded from the test.
Eventually when it is live and not a test, I hope that we still get 4K but without HLG. The specifications indicate that the app will drop the HLG. If I read it correctly. When it is out of the test phase.
I think.

I just go into iPlayer on my TV and it is an item on the front page.
My TV wasn't on the list of supported devices when I was able to watch a match, but is now. I assume the list was not complete, and still might not be. It is noticeable there are some other devices listed now, such as PlayStation 4 and Virgin V6 box, so you might be able to get in that way if your TV isn't compatible.
Here is the list: https://www.bbc.co.uk/iplayer/help/live-uhd
4K will be a given for sure, and probably HGL for certain broadcast. As 1080 is now, 4K will be the standard in a few years time as more and more programmes are being recorded in native 4K, although the BBC are still filming in 1080 in the most part for whatever reason. 4K is pretty much standard now for all broadcast sports from Sky, has been for quite a few years really.
Then just as you get used to 4K, they'll be forcing you down the 8K route lol
Not forgetting BT Sport pipping them at the post for a standard broadcast but I think BT are waisting opportunities. They cover some lower league footy in 4k and leave out top flight rugby on the one channel.
I don't have sky so not sure what they provide to the customer at home but then they don't have much rugby. Wonder what the bit rate for video in down to the home, are Sky IP or satellite for 4k? Not ground to studios, the downlink or internet.
NHK are already running 8k in tests and will be doing it for the Olympics. Small reception I think, obviously.
Certainly going to get interesting.

Found the time to flick though bbc 4k trial t.v. List.
My Sony doen't make the list as I had suspected , my purchase date was July 2016- possibly manufactured 2015.
Today bbc are reporting a new 4k Wimbledon trial to be broadcast as you guessed it part of the very limited trial.
Enjoy, I'll continue with q upscaled hd to uhd resolution.

No offence, but "upscaling" is a bit of a myth really. It was marketing department's way of selling 4K TVs to people when there wasn't any 4K content to watch. Any improvement is likely to be because the panel is better than the old HD set you had before. The upscaling provided by software will be marginal at best. That's just my 2p's worth. If you're happy with you're seeing then that's the main thing.
That's why I'm a strong believer in HDR being the game changer. 4K makes little difference compared to HD (unless you're sitting about 2 feet away from the screen). It's to do with how much detail your eyes can perceive (Google "retina display" and read the maths behind it).
I've been watching the UHD/HLG streaming coverage from the BBC of the World Cup on my 2017 LG set and it's very nice. Not quite the quality you get with Dolby Vision on Netflix, but great for broadcast and noticeably better colour definition than HD. I've been able to access it all so far without ever being a victim of the limits that were mentioned. Either they're not hitting the limit or I've just been lucky.
It's great news that Centre Court on Wimbledon will be getting the same treatment this year. The report about it mentioned UHD but didn't say if it's HLG. I hope (for the reasons outlined above) that it'll be HLG (HDR) and not just 4K.
EDIT: Article updated on the BBC web site. The Wimbledon coverage will be in HDR.

Depends what is being upscaled. Upscale SD and its rubbish no matter the set. (edit, 4k that is)
All watchers are different and this watcher is more tan happy I can see 4k over 1080i. Even on broadcast live stuff.
Read the maths, seen the charts, use them as a guide. Not all eyes are equal.

This had been debunked multiple times. It is based on a person being able differentiate 1 arcminute with 20/20 vision. Many people think 20/20 means perfect vision, it doesn't it means average vision. Some can see 0.4 arcminutes. I can see better than 20/20 with my glasses, which is not uncommon, and 10-15% can without glasses. There is also vernier acuity, the ability to see disalignments smaller than the spacing of retinal receptors. But it is not a level playing field...
I can certainly see more detail in the UHD broadcasts. I have swapped over to the BBC HD broadcast on the same TV, and also looked on a 1080p TV to make sure it wasn't upscaling issues. However, that might be due to the extra bandwidth of the UHD broadcast.
Having spent a good 45 minute with tonight's current game. There's a nice bump in dynamic range from the SDR 8bit rec709 colour to HLG Rec2020 which is 10bit.
But, as I keep saying, after a few minutes you tend to forget the extra crunchy visuals, which is the same experience I've had with F1 in UHD, and you tend not to notice it. Your eyes soon adjust. HLG does indeed works well for broadcast though, and that is the whole point of this BBC test broadcast. Remains to be seen if this becomes a broadcast standard wold wide.

All the while wondering how the Apple process is preventing this happening for the ATV or is it the Beeb not updating the app.
I would think that the basis for feed would allow the stream to hit the ATV and then pass what is needed to the panel. Those of us with older panels could still get 4k, the standard they are testing allows for this.

Argentina v Croatia game via bbc live t.v. -Sky q (not iplayer)
Quality was very 4k on my non hdr Sony 43" 4k screen.
I had confirmation when viewing via Skyq -the upscaling is processed via Q box.
I wasn't sure as my Sony t.v. Is setup to display 2160p uhd resolution.
Either way last nights picture quality was ver 4kish indeed.
Highlights from Iplayer via 4k Apple t.v. -very nice quality.

Here’s the article from the BBC regarding Wimbledon. UHD transmission coming to SkyQ and HLG test again on the iPlayer.
I could be down the Apple wether the Beeb cam update their app for HLG without Apple being heavily involved programing wise. Quite a small market share for iPlayer I would have thought too. Not worth the efffort? Especially when all the TV’s or the vast majority of them, that can handle HLG will have the iplayer app preinstalled?

Of course. Doh!
I was thinking how many Apple TV's there are not how many actually use 4k and over thinking it forgetting the sales of panels.
However it occurred to me that the BT UHD box also not on the list, I wonder what the sales of 4k devices past the sky/bt/apple are. That is more people are buying the panels and that vector is greater than the 4k box. I understand that some sales figures are showing the sales are greater than the same time period for HD.

Sky only have around 600k homes with Sky Q and not all of those have 4k TV sets so depending on the number of 4K sets out there and virgin V6 boxes iPlayer may have a bigger 4K audience than Sky. There may be more Apple TV 4k boxes connected to 4k sets than sky has Sky Q connected to 4k sets.
