The TV Question Amnesty Thread

(Canon and Fuji seem to sell either beige or black only cameras).


Do you mean lenses? Canon and Fuji don't sell broadcast cameras.

The cameras are usually Sony or GVG (aka Philips) with Ikegami, Hitachi and Panasonic also in the game (though in Europe it's really Sony vs GVG) whilst the lenses are usually Canon or Fuji.

I think that desk on GMB could do with being a few meters longer. I like the desk Anne Diamond and Jeremy Vine use every morning over on the other channel. It’s quite long and very spectacular.

The GMB desk feels as though it’s been crunched up deliberately. Was the original desk longer?

Yes. The original desk was oversized, I think deliberately as part of the US TV influence.

Oh my. That's a properly 'And me' terrible promo...

BBC News: Presenters & Rotas

Rkolsen posted:
Does the BBC have a directory of all their correspondents and maybe bios? Sometimes I don’t catch a persons name but I’d like to look them up. Even something as simple as a photo gallery index page of all their on screen talent sorted by role or region would be nice. It doesn’t have to include once in a blue moon freelancers but the permalancers and those under contract.


It used to have those kind of pages in the days when the BBC had bespoke websites and pages, but the teams who created that kind of content disappeared in cost-cutting years ago. You may find some regional operations keep 'presenter pages' up to date.

Keeping that kind of content up-to-date is time consuming, and doesn't really fit into anyone's remit these days AFAIK.

Does anyone know the audio spec for the live sports coming through the NowTV Roku app?


I'd be very surprised if it wasn't AAC 2.0 output as PCM 2.0 - or is there a suggestion it might be Dolby 5.1?

I've done a bit of digging, and seems it was on Granada Breeze.


That would fit. Think it appeared as a Tivo suggestion and I series linked it for a while.

Edit : Since a lot of you seem to talk about The View and bring it up in the Loose Women thread do you think the show would do well over in the UK? They don’t really have sponsored content, rather promotional consideration (such as giveaways).


I'm sure it was on-air here in the early 00s when I had a Tivo connected to my Sky box, as I used to watch it reasonably regularly. I guess the fact it's not carried by any major channel here now tells the story it didn't do so well? It is a very acquired taste if you aren't an American.


Was it not on Diva TV at one point (this would have been around the late noughties)? I remember they started out with quite a varied lineup, but then for its last year or so on air it was virtually wall-to-wall Oprah.


I'm talking pre-2004 - I'd stopped using a Sky Digibox-fed-Tivo by then.

Question about UK TV Weather presentation

Inspector Sands posted:
Possibly also to do with the way that the prevaling weather here normally comes from the west? If the presenter stands on the left they can gesture this with a pushing motion rather than pulling across which looks more awkward?


One more obvious reason could be that if they stood on the right they'd cover up northern France and the Benelux (and now in 16:9 days, Denmark too) although they're not part of the UK, people do go there and of course the BBC has been available in The Netherlands for many years. Of course that means obscuring Ireland but only partially


Yes - if they stand on the left of frame they are only covering up the Atlantic, whereas if they stand on the right of frame they are likely to cover Benelux countries (where BBC One and Two have been legally available for a long time)

Following the recent issue, sadly, I don't see Ben Thompson going anywhere, in an upwards direction, anytime soon.

Yeah, I agree. He also doubled down it seemed by posting a picture of him and his husband (or partner) on Instagram (linked on twitter) kissing. Right after making statements were condemned. It almost seemed like he was telling the BBC I dare you.


Or just living his life as normal. The fact that a picture like that is even comment-worthy here is making his point for him.

My TV dosen't qualify for these UHD HLG tests, but I presume when Sky Q eventually implement it, the box will do a 4k SDR conversion, presumably if it picks up an UHD HLG signal in future?


Not sure. I don't know if the chipsets in the Sky Q support HLG HDR->SDR tone mapping. However HLG is designed to be 'sort of' backwards compatible with SDR. This means that as long as your display supports Rec 2020 wide colour gamut sources in SDR, then the pictures should be reasonably watchable (the HLG EOTF, or what we would have called 'gamma' is quite SDR-like until it gets to around 75% then it curves more than an SDR power-law gamma to avoid clipping. HLG receivers 'uncurve' this into the highlights, and when the HLG is viewed on SDR receivers just look like the cameras have a bit of a heavy 'knee' in them I think (so you see more detail in highlights, but dimmer than it should be).

This is another reason broadcasters prefer HLG over HDR10/DV PQ systems - as PQ formats require significant tone mapping processing to convert to SDR (and as anyone who has watched a UHD HDR Blu-ray in UHD or HD SDR can tell you, this is still not an ideal process. If you watch an unconverted PQ signal on an SDR display it looks terrible.

Sky Q will need to be able to flag HLG Rec 2020 over the HDMI output of the Sky Q, and render their OSD, subtitles etc. in an HDR-friendly format so they look OK when overlaid over HLG HDR pictures, to output HLG HDR. They also need to consider SDR UHD, HD (and SD?) displays I guess.

They may decide that outputting HLG HDR Rec 2020 to SDR Rec 2020 displays is acceptable rather than conversion (though the BBC may take a different view I guess when it comes to certifying Sky Q for UHD HDR) I don't know what they will do for Rec 709 HD output though... (My guess is that Sky's SDR UHD output is Rec 709 not Rec 2020 so this hasn't been an issue in the past)

HDR UHD content usually uses Rec 2020 Wide Colour Gamut as well as an HLG or PQ EOTF.
SDR UHD content is often Rec 709 Colour Gamut (same as HD) with a BT.1886 or "Rec 709" power law gamma EOTF. SDR UHD Netflix is usually Rec 709 not Rec 2020...

I forgot to mention my 4k tv is an early adopter SDR 4k tv it dosent do UHD HDR/HLG I am worried that when this becomes standard on my tv the 4k is going to look dull, in Italy they have 4K HDR already but looks like they have two 4k modes on their Sky Q.


Does it support Rec 2020 or just Rec 709/BT.1886 and Rec.601 gamut sources?

Looking Superb on the iPlayer again.

Is it meant to look a little dark in UHD? The team name background on the scoreboard isn’t white for example. And if I turn on HDR+ via the Samsung menu it goes very dark - the same happened for Blue Planet too.


It’s definitely a bit sharper than HD but not sure it’s blowing me away in the way I hoped.


The reason HDR stuff often looks darker than SDR on HDR displays is that a lot of people watch their TV with the SDR content pushed well above the SDR brightness range and into HDR levels. HDR TVs can go so bright, people often like pushing their regular viewing to be brighter.

As a result HDR (particularly PQ and specifically DV stuff that fixes the light level output to the video signal) can look dimmer.

In theory SDR peak white should be around 100nits, and the same content in HDR should hit around the same level, and then highlights and speculars go above this into the >100 nits range.

However most people watching SDR content on their new shiny HDR displays push their SDR peak white well above 100nits, and into the HDR range. As a result the HDR version will look dimmer.

If you imagine a person wearing a white football top on an overcast day. If that is bright in SDR, but not bleaching out, on a correctly lined up TV, it will probably be around 90nits. However if you wind up the contrast/brightness/backlight etc. on your TV to push this into the 200nit+ range, it will make the whole picture look nice and bright for SDR.

If the sun comes out, then the vision operator either has to make the rest of the picture dimmer to avoid bleaching out the shirt, or let the shirt bleach out (they key is to keep faces looking right and for cameras to match each other) If they let the shirt bleach out you'll get a very bright picture with bleached out highlights.

If you watch the same match in HDR, in overcast lighting that correctly exposed top will still sit at around 90 nits and thus look much, much dimmer. However if the sun comes out, the vision operator can let the highlights 'go' and the top will get brighter and brighter and still have full detail in it.

That's what HDR is for - detail in highlights and speculars - not about making the whole picture brighter. However because people are watching their SDR content much brighter than it would be if seen in the SDR range of an HDR signal, the two look very different.
