*** Sky Q Thread ***

What programmes is it happening on to see if we can reproduce, might be an issue with the actual broadcast itself.

An old Dalziel and Pascoe episode on Alibi recorded before this new firmware drop. Also BBC news when they showed a longish item on Russian athletes (happened Thursday at lunchtime and the six o'clock news). I'm now wondering whether this is actually a broadcast issue.

 

[Cosimo]

Downloaded a pascoe episode from 16th july and it was fine on my system.

I'll post on the forum anyway, can you post if it happens again please.

Others having the same problem:

Is this juddering issue where it jerks repeatedly and pixellates with large blocky-type effect?

If so then I had it the other night but a restart of the TV fixed it - it is a Sony, same model as Cosimo.

Sounds familiar.

Looks like the Q tech team are aware of the juddering issue and are working on a fix asap.

In the mean time, the options are to switch inputs and go back or to turn off tv and back on.

Must be something within the TV, as they're a few models affected. They are in contact with Sony regarding the fix.

Cheers.

Good to see it's got high priority for a fix.

Happening in the BT UHD channel as well according to that thread Cosmo. Wonder what the issue is with the Sony TVs.

It is very odd. Ours has been perfect since the three events on Thursday and Friday morning.

Our TV HDMI signal format has two options, standard and enhanced:

[Enhanced Format] displays High-Quality HDMI signals. Select this option only if your device supports High-Quality HDMI formats such as: 4K 60p 4:2:0 10bit, 4:4:4, 4:2:2 (HDR included)

It has been running on standard HDMI signal format.

As it's settled down I will switch it to enhanced to see what happens.

Statement from Sony on the juddering:

[Cosimo]

Now also running on enhanced HDMI input without any issues.

 

[Cosimo]

What's this standard/enhanced HDMI format thing? Is this a function of the TV or the Sky box?

This is a TV function which allows individual control of all you HDMI ports:

Viewing picture in 4K resolution or HDR with High-Quality (4K models only)

When you display in High-Quality 4K or HDR format* using HDMI input, set [HDMI signal format] in [External inputs].

The availability of the HDR feature depends on your model/region/country.

1.Press the HOME button, then select [Settings] — [External inputs] — [HDMI signal format] — the desired option.

Available options

[Standard format]Standard HDMI format for normal use.
[Enhanced format]High-Quality HDMI format.

Set only when using capable devices.

Note

•In [Enhanced format], the picture and sound may not be output correctly. In this case, change to [Standard format].

•Only for devices supporting High-Quality HDMI format.

•When you watch 4K/HDR picture with High-Quality*, use a Premium High
Speed HDMI Cable that supports speeds of 18 Gbps. For details on a Premium High Speed HDMI Cable that supports 18 Gbps, refer to the specifications of the cable.

•For some models, the [HDMI signal format] of HDMI IN 2 and HDMI IN 3 changes at the same time.

* 4K 60p 4:4:4, 4:2:2, or 4K 60p 4:2:0 10bit, HDR, etc.

To enable HDR on our UHD HDR Blu-ray player the port it uses is set to enhanced.

We've also got Dolby Digital enabled in the Q box as the TV does process this.

 

[Cosimo]

Ah ok thanks. I'll check this but pretty sure it's enabled by default - the Sky box has detected and switched to 2160p 10-bit and I'd assume this is only available if the TV is set to enhanced mode, otherwise it'd likely revert to 8-bit.

TV is set to standard by default.

Android app has been updated:

Finally looking good on Samsung Note Pro 12.2.

Cosimo, my TV flagged up an update this morning but I've not installed it yet. Wonder if this is to address the issue?

What I previously mentioned obviously wasn't the juddering issue talked about by others but I think I had it last night. Turned the TV and box on and tuned to Sky News and the ticker at the bottom was jerking very regularly (as was the rest of the picture obviously). Turning the TV off and on again solved it.

I put this one on last week and it does not. It is an Android update:

[Cosimo]

Ah ok, does it fix or change anything of interest? Any Youtube HDR support yet?

I don't know what it fixes as to the HDR you'll have to try and see if it does.

[Cosimo]

Enhanced is only for PC's really, nothing else will support it. Best to leave it off.

Rubbish, it supports devices that output 10bit and the includes 4K UHD Blu-ray players that output 10bit HDR.

@cosimo

Looks like the Q tech team are aware of the juddering issue and are working on a fix asap.

Is that it for UHD firmware drops before official launch?

 

[Cosimo]

Except my Sky box will detect and switch into 10-bit even if the HDMI input is set to standard, which is what I don't understand.

Probably just detects a 10-bit capable screen and outputs that format irrespective of the receiving end.

 

[Cosimo]

Am I going nuts, there is a Ultra HD entry in the Sports menu but none in Sky Cinema?

 

[Cosimo]

Sky Cinema will be download only, not live broadcast.

Doesn't matter as you still have to find which ones are in UHD so there should be an entry.

 

[Cosimo]

A limited amount of UHD content will be made available from around midday tomorrow.

I know, just wondering where it will appear on the menus.

 

[Cosimo]

Under each section.

For example. Main vertical section. Sports then UHD

So tomorrow there will be UHD entry under Cinema just as we have one now under Sports? I thought all the menu placements came as part of the firmware drop and not some on the fly?
