Re: iPlayer HLG/UHD HDR on Samsung’s J and K Series TVs - Page 434

So, of the nigh on 400 TVs supported in BBC iplayer for the Blue Planet II HLG episodes none are from Samsung. Oh joy.

...

Moderator edit: Original thread title was "Blue Planet 2 HLG - No Samsung".

Did you see the photo I posted?
It is my updated 65Ks8000 television for HLG

It shows HDR but not HLG or am I missing something. We know the ks can receive HDR10 But not HLG over HDMI. I have never heard of such censorship from a forum, and why restrict as I thought all the European versions of the ks were the same, so if it works on yours it should work on ours. Again sounds a bit like mischief to me.

You're wrong and told by the administrator that only serves for Italian and not foreign as they are writing from all over Europe. this version enables the HLG HDR

But your picture proves nothing as we know the TV can receive HDR over HDMI. It does not show HLG.

Are not the TV's the same in Europe or did Samsung make a different TV for each country in Europe?

every nation has different specifications within the TV, they are not the same.
Software specifically for the English market should be developed

Fair enough, we have waited this long, so have you any idea when it may be rolled out to us? But still not holding my breath.

SmartHUBtv · ‎23-11-2018

I have personally been waiting for almost 2 years!
can 'be a week as a maximum of 1 month we start with the release of the update on the samsung site and then automatically via internet on TV, usually in Italy works this way.
The administrator of this site is not the first time that it releases to the users of the forum exclusive updates, in 2014 he did the same with the 4k on the samsung tv

Hi mate, its the forums right to not share the firmware but I would just like to clear this up as you have mentioned this a few times.

take the KS8000 for example, model string for both italian and UK markets is T-JZMDEUC. If you where to check the current firmware which is available (1230.5) you will see both UK and italian firmware downloads are the same right down to the checksum, any change no matter how miniscule would alter the checksum and in all liklehood alter the file size.

If you where then to check the USA website which uses a different model string you will see this is different.

info.text from both UK and ITA KS8000 1230.5 firmware file

anyone is welcome to check this themselves

edit... I think @blenky may have mentioned this earlier in the thread but talked about a KU set

cheers

paul1277 · ‎23-11-2018

And I think that proves the point that the TV's are the same. So why not let us see if it works? Why is it just restricted to Italy? Again I think mischief and miss information, and yes you can tell us every thing now works but it does not for us and we have heard the same from the same part of the world!!!

But that doesn't prove that Samsung have fixed the HLG problems, specifically to correct the HLG EOTF gamma curve for HLG content. This "fix" needs to fix two things:

1. Correct the TV's EDID to allow HDMI connected devices to detect an HLG compliant TV.

2. Correct the HLG EOTF gamma curve for all HLG content.

Has anyone with this new firmware actually tested some HLG calibration test content to measure whether the luminance response curve matches the correct HLG EOTF curve? If so, what was the maximum NITS measured on a 10% window at 100% luminence? On the old non-HLG firmware, the maximum was less than 500 NITS, so nowhere near the maximum luminance the TV is capable of.

Until someone does that, we have no idea if this test firmware completely fixes the HLG problem on KS TVs.
