Oh, also is there a list of who is doing what event for OBS?


I've not seen anyone reply to this yet, so courtesy of SVG:

Quote:
Aquatics: OBS handles everything, with the exception of Marathon Swimming, which will be produced by Sky TV New Zealand.
Archery: SBS Korea
Athletics: YLE Finland will handle all events in the Olympics Stadium, and VRT Belgium will produce Marathon and Race Walking.
Badminton: CCTV China
Basketball: OBS
Boxing: ICRT Cuba
Canoeing: Sprint Canoe will be produced by the BBC; Slalom Canoe, by Czech TV.
BMX: OBS
Mountain Biking and Track Cycling: RTVE Spain
Road Race and Road Race Time Trial: VRT Belgium
Equestrian: OBS
Fencing: OBS
Football: Globo Brazil is producing matches in São Paulo, Belo Horizonte, Salvador, and Maracanã; NHK, matches in BrasÍlia; OBS, Manaus matches; and YLE Finland, those at the Olympic Stadium.
Golf: NBC Sports
Gymnastics: CCTV China
Handball: OBS
Hockey: NOS Netherlands
Judo: NHK
Modern Pentathlon: OBS
Rowing: BBC
Rugby Sevens: Sky TV New Zealand
Sailing: OBS
Shooting: OBS
Table Tennis: OBS
Taekwondo: SBS Korea
Tennis: BBC
Triathlon: Sky TV New Zealand
Volleyball: Indoor Volleyball will be produced by Fuji TV Japan; OBS, Beach Volleyball.
Weightlifting: TVPT Poland
Wrestling: NHK


Reason Rowing and Spring Canoeing both done by the BBC is that they are in the same location.

I think historically the BBC have been host producer/broadcasters for Tennis is Wimbledon, and rowing is The Boat Race... (Not sure they've done Tennis every year, but ISTR they did it in Barcelona in 1992...)

Assume YLE doing all Athletics this time is because SVT (who historically do jumping) no longer have Olympics rights (though in theory they could host broadcast produce coverage anyway - I doubt they would produce stuff their audiences at home couldn't watch).

Why they've moved EastEnders to Wednesday next week is also a question.


Could there be more Team GB-friendly sporting events on other days, with that time slot on Wednesday less likely to feature events that generate Team GB medals?

Question for those in the know. Is this being backhauled to Salford for production like Sochi?

No - BBC One/Two and BBC Four stuff is being produced from on-site galleries in Rio. The Summer Olympics has a much higher level of on-site production (as it is far higher profile) than the Winter Olympics stuff, which is usually produced remotely.

(Sochi and Vancouver were uni+multis fed back to the UK, Torino/Turin was on-site studio cut and fed in Turin, but backhauled as a Uni, with Munis - which were the HD->SD 16:9 downconverts made just for a couple of broadcasters, for the 16:9 SD event coverage)

Quote:

The interviews have a really short delay in both directions for Rio and that delay was so annoying for Sochi.

I think IP is also being used rather than SNG (or convenional HD-SDI over fibre) to get circuits back to the IBC, so also no satellite delay even between venues within Brazil, outside Rio.

Now, I'm watching 4K stuff on Netflix and I'm trying to work out if anything actually looks any sharper than 1080p.


Does it downgrade if the bandwidth isn't up to it, and does it give you an indication if it does so? Or maybe they're just compressing it too much to squeeze down the tubes.


Whether you get an indication of received resolution depends on the platform. Our Sony UHD set with the integrated Netflix app displays it on the OSD (2160, 1080, 720, 480 etc.)

The Netflix UHD stuff is low-bitrate and has clear compression artefacts if you look closely. Miles away from the high bitrate stuff you get on UHD BLu-ray.

Yes the coverage of the team finals in gymnastics was rather disappointing.

Surely it can't be that difficult - from either a technical or resources point of view - to cover every routine on every piece of apparatus, and then direct the coverage to show a mix of live and recorded routines during the 'live' coverage in order to tell the story as fully as possible. But the mortal sin is to display leaderboards which reflect routines which haven't been shown yet.

Similar to golf, I suppose. A lot of what you see in 'live coverage' of golf is actually recorded.

I suppose the extra difficulty is having commentators in the venue where you can hear the stadium sound in the background. For example, last night the BBC showed a recording of Claudia Fragapane's floor routine. But literally just as the recording was starting, you could hear the stadium PA announcing her floor score in the background of the commentator's mic.

I'm not a regular gymnastics viewer, so I don't know whether this is the norm for team finals or whether its just an OBS thing. But I found watching the coverage rather frustrating.


Expensive to do. You'd need on-site production or a remote production gallery just to do that for the BBC. Serious money. (Which is why only NBC really do it - they pump insane amounts of money in)

Japan isn't... They still shoot HD drama at 60i there


We should take a leaf out of Japan's book!


To be fair, it's a bit less common than it once was.

I remember being really surprised at seeing a Swedish costume drama, with great production values, shot 50Hz. It was one of SVT's first HD productions I think (c. 2006?) and had 'film type' lighting and grading, but 50Hz motion. Really nice - but a bit odd. A bit like watching movies with Natural Motion/Motion Flow switched in...

Louisa James in the GMB Newsroom for a Breaking News!
That's great!

Very interesting as Charlotte usually gets the news lines on her PC, as would Kate and Ranvir.


There's a difference between reading a couple of News wires and some copy out on-air and actually doing some journalism though...

First 8K broadcast

UHD does need larger screensizes for most people with average eyes to see the benefit of it at usual domestic viewing distances.

We switched from a 40" HD display to a 50" UHD display and kept the same viewing distance, which is probably closer than usual. We didn't buy it because it was UHD, but because it was a better quality display than many HD displays we looked at (once we'd spent 30 minutes adjusting them all with the remotes, disabling all the horrific digital processing bobbins)

UHD 4K definitely offers benefits on the larger domestic displays 50-80" territory. UHD 8K really only offers benefits on larger screens - but is stunning when you see it. 8K at the cinema should be amazing. (4K is still a massive improvement over 2K)

Gymnastics commentators expressing frustration the coverage isn't showing the British team, but obviously saying they can't do anything about it.

He's right. And it's something that isn't going to change unless OBS give major market rights holders/broadcasters access to the event camera ISO feeds.


Which in some cases (NBC - cough) they do. Also rights holders can apply to put their own cameras in alongside OBS cameras (NBC - cough) but the costs of doing so are probably prohibitive for most.

However ISO feeds aren't that helpful if the cameras aren't pointed at the right things and being directed properly.

I agree, HDR and high frame rate are far more practical technologies in the normal home... At least you can see the difference in a domestic setting. 4 and 8k are impractical in a house


Though I almost wonder why they'd bother with HFR when they're so obsessed with sticking a low frame rate "film look" on everything these days.


Japan isn't... They still shoot HD drama at 60i there (though they do also use 'film effect') - and very few sports anywhere use 24-30p. One of the selling points of the latest Apple TV was MLB at 60p rather than 30p ISTR...

Japan has just done the world's first 8K TV broadcast.


A long time ago...

I saw live 8K pictures from London in Amsterdam about 7 or 8 years ago, along with a stunning showreel.. I saw live Swimming at London 2012 in 8K, along with opening ceremony highlights. Both were delivered over IP or from local playback.

NHK have use cutting edge modulation schemes to terrestrially broadcast 8K stuff, as well as via satellite (which is easier)

The stuff I saw was 7680x4320/59.94p (aka 60p) - I don't know if the Rio stuff is now HFR 120p (or the 1000/1001 equivalent)

DVB Cornwall posted:
Disagree with the 4K remark above having had it for 9 months the difference is astonishing. 8K will have to wait though uncompressed 8K is a whopping 190mbps compressing that down for service broadcast will be an order of magnitude more difficult than anything we've seen to date.


Where did you get the 190Mb/s figure from? The 190Mb/s is almost certainly a heavily compressed H264 or H265 signal...

Uncompressed 8K is huge orders of magnitude higher than that, after all uncompressed SD is ~190Mbs...

7680x4320 at 4:2:0 10 bit 60 fps would be : 7680x4320x60x15 = ~30Gb/s (30,000 Mb/s)
(The 15 is to handle 10 bit 4:2:0 where 1 10 bit Y sample is accompanied by 50% of a Cb or a Cr sample)

If you go for full-fat 4:4:4 120p then it's 7680x4320x120x30 = ~120Gb/s (120,000 Mb/s)

For comparison :

1920x1080 60i 4:2:0 8 bit would be ~750Mb/s
3840x2160 60p 4:2:0 8 bit would be ~6Gb/s (6000 Mb/s)
