Hello everybody
Where is the problem that on the NASA UHD channel with HotBird 13E I have a frozen image and the sound is there? when I watch this channel on the phone on the VuplusTV application, the channel is working properly.
On the TV, when I switch to NASA UHD, the image changes its resolution to 3840x2140 but it is frozen (like a photo), the sound is there.
Other 4K channels work fine.
My Image is OpenPli 8.1 Nightly Build Last update + Tuner VU + UNO 4K SE.

On which box and in which mode…. The channel is 30 fps. Some boxes in eg mode 12 cannot play it.

Same behavior lunix3-4k/solo4k.

fps 59i !!!!

[littlesat]

So it is p60…

[ims]

It is 4K p60. I think, hisil boxes will be successful on it only...

I have VU + Uno4kse.
resolution set to 1080p with auto refresh.
I've changed these settings but it doesn't help. Some time ago, this channel functioned normally.
I watch other channels in this resolution and p60 normally (they are not permanently frozen).
I watch on the Iphone and the data is as shown in the picture.

Ok.
In the previous post, I wrote it wrong.
Other channels are broadcast in 4K but with the p50 and I can watch them. 4K p60 channels are the problem.
Is it a VU + or TV box problem? My TV is Sony KD-55XF9005.
And the question that by streaming NASA on the phone, the application lowers p60 to p29. TV or box can't do that?

box problem

[littlesat]

A friend of my had a Sony years ago.. and had that time such issues.

[bodekbp]

I understand that the problem is in the TV and not in the box?

[Dimitrij]

Problem is in boxes ... tried duo4k, e4hd, h7s, vs1500 and multibox. Only multibox (hisil) works on same TV (Philips) well.

thank you for the tip.
Apparently they had been broadcasting this channel with less p before, because this channel was working normally.

Same behaviour on osmio+ 4K

[Dimitrij]

Abcom pulse 4k work fine.

VU+ Solo4K only audio.

[ricki]

gbquad4k work fine

fyi,  Has nothing to do with the frame rate.

The resolution and frame rate has not changed.

 

The difference is that previously NASA UHD used 8 bit color depth.
Now they are using 10 bit color depth.

At least that is what we see on 127w.

 

So 8 bits = 2^8(bits)^3 (3 primary colors) =     16,777,216 colors

10 bits = 2^10 (bits)^3 (3 primary colors) = 1,073,741,824 colors

octagon sf8008 is fine here, I would expect any respectable / modern 4K STB to be playing OK.

some other off brand / cheap chinese STBs maybe not so much?

I do not understand it? on the box vu + zero 4k works, and uno4kse not on a slightly better one? where is the difference?
