UHD football on Stream

mweir — Mon, 19 Feb 2024 20:49:16 GMT

Hi all

I have Sky UHD through satellite and TNT Sports UHD through their streaming box. The UHD picture quality on TNT is far superior and I'm wondering if it's due to the satellite.

I'll happily switch to Sky Stream if the picture quality is as good as TNT. Anybody got both and can let me know?

TIA

@mweir Unfortunately no one can have both Sky Q & stream as it's not allowed so a side by side comparison can't be made.

UHD on stream is on a par with the satellite delivered UHD live sports channels.

@GD1 sorry, I mean people who have both streaming service TNT Sports UHD and Sky Stream UHD and can give me a picture quality comparison.

as I say, my Sky UHD is through my SkyQ box and the picture quality isn't a patch on TNT Sports UHD. I was hoping someone could give me better news about the Sky Stream UHD quality

@mweir I've got Stream and TNT and the picture quality is outstanding and far superior to TNT Sport Ultimate on BT TV...

@Nigelb1972 that's good to know as I think TNT Sports is excellent quality so is Sky Stream is even better then I'm in. Sky Q satellite UHD is barely HD quality

@mweir a gentle advisory though, Sky Stream uses HLG as the HDR codec so make sure your TV is compatible. If it is, the UHD quality is outstanding...

@Nigelb1972 Cheers, I've got 2 LG OLEDs and a Samsung Qled so I'm fine on that front 👍

Hey- I've had Sky Q (Satellite) UHD, Sky Stream (UHD), and I've also watched TNT Ultimate (UHD) through all formats.

Sky Sports is outstanding on stream for UHD.

TNT Sports Ultimate on Stream, Satellite and Discovery + app is not as good as Sky Sports is- I believe this is because Sky Stream and Q HDR format is HLG, whereas TNT Sports is filmed in a different HDR format and therefore it loses something when converted to HLG of Sky.

The best picture I ever had for TNT Sport was when it was with the BT App before Discovery brought them out. I'm guessing therefore your BT Box probably gives you that same amazing picture - so the best TNT Ultimate picture will be on there. I'd say Sky Sports UHD on Stream is also excellent now.

Just a shame we can't seem to nail both on on platform!!

The camera's capture the raw footage with higher dynamic ranges than TV's can typically display and the software codec's are added during broadcast. HDR10 uses more bandwidth than HLG as it was designed ebe a standard for UHD Blu-ray but HLG was designed by Nikkon and BBC to be used for broadcast content and is comparable to, if not better than HDR10 for broadcast purposes as it uses less bandwidth.

Dolby Vision again uses more bandwidth and is probably the best quality HDR codec with HDR10+ following closely behind.

BT Sport used to use HDR10 as their codec of choice but Sky re-broadcast the source material in HLG.

Personally, I've had BT Sport delivered via their app, the BT TV UHD Youview box and their Pro Box and the best picture quality has been via Sky Stream using HLG..

The quality is also dependent on high much video compression and audio compression is used. Netflix used heavy compression so their UHD content is barely above Blu-ray HD for me.

Sky & AppleTV have the best compromise for me with Amazon Prime close behind.

@SKYLJM It is likely due to Stream using 36 bit colour as opposed to Q using 24 bit colour. UHD/HLG sports is outstanding.

The simple reason is TNT sport is in HDR and Sky uses HLG. HDR is far superior to HLG (HLG is a stripped down version of HDR).

Anyone who is saying that Sky is better is a shill...it is NOT superior to either the TNT/Discovery app or the BT/EE box.

I have both Sky Q box and BT Box.

Sky is great in 4k but it is light years behind even the old BT Sport app.

Obviously on a Sky forum everyone is going to cheers Sky...its like going to a PlayStation forum, where everyone will cheer PlayStation...

Not strictly true.

HLG (Hybrid Log Gamma) is a format of HDR. It is used by Sky and the BBC (via iPlayer) for their UHD HDR streams.

TNT Sports uses HDR10 which is a different format of HDR. HDR10 is the most common and basic HDR format used by all the main streaming apps (Netflix, Disney+, Apple TV+, etc) for their UHD HDR output.

Both formats can look excellent but a lot depends on the peak brightness of the TV you use. A TV with a high peak brightness can show HLG extremely well.

This is not true.

Whist HLG is a format of HDR, HLG is a stripped down version , hence the reason is has been adopted...becuase it is missing alot of metadata of HDR10 it is easier to transmit (and capture).

It is true but believe what you like. I work in TV post-production so I'm happy to pass on factual information.

HLG and HDR10 are both HDR formats. Fact.

This may help you understand them better:

I do know that...

My point was that objectively and scientifically the Sky in HLG is NOT better than TBT Sports when both are played in 4k UHD.

This is in response to the majority of respondants here saying that Sky was better...

Make no mistake I would 100% advise anyone considering the 2 services to go to Sky over BT but to say its better is simply wrong (because HRD10 used by TNT is a better format than HLG).

And the TNT/Discovery app is next level...for so many reasons that no one else has adopted (goal notifications on other channels, easily going to each and every match incident rather than ff or rewind etc)

Both UHD serices are premium though...and highly recommend.

Saying one is better than the other is kind of pointless because, as I said earlier, it depends on the TV the viewer is using.

A TV with a high peak brightness can and will show HLG HDR at a higher brightness level than HDR10 (which has the peak brightness fixed at source). HLG checks the capability of the TV before setting its brightness output level so in some respects, if you like your image to be bright and punchy and your TV is capable, the image quality from HLG could be seen to be 'better' than an HDR10 output.

It's all very subjective. Basically watch what looks best to you on your TV, and as you say, if you like sport, get both services.

I personally don't watch sport so I don't really care what format it's shown in. Watching some folk kick a ball around or some cars bombing round a track are equally tedious to me in 480P SDR as they are in 2160P with HDR. I watched a live stream of some football in 4K with Dolby Vision & Atmos at an industry event last year. Nearly fell asleep.

This steam is about UHD football Buddy and given you're arguing this point and lurking in Sky forums as a hobby says it all really...

For anyone else you can check what I've said by a quick Google...

1, is HLG a poor man's version of HDR10...yes it is because it is missing metadata

2, Does Sky use HLG...yes it does

3, Does TNT/Discovery use HDR10...yes it does

Would love to know more about this missing metadata so I can pass it on to all my post production colleagues. Perhaps we'll send out a search party to try and find it... 😉

Enjoy your footy! 😘

is it in HDR10?

when i view TNT ultimate it says HLG on my TV. (I have stream)
Also no atmos on TNT either. (there is if watched via BT/EE TV as I used to have it and that did use HDR10.)

if sky could fix the atmos issue that would be great.
