The Sport Thread

The decision on the Canadian Grand Prix, as to whether it'll go ahead on its original date, or be moved, is to be made pretty soon.

Take a break from the net for a few hours and they only go and decide to restream the 2012 Opening Ceremony - it seems to have gone down very well with those who watched it.

I might dig out the DVD myself but do feel I should probably get round to watching the other 4 DVDs in the box set.

The whole opening and closing 2012 ceremonies have been on the official Olympic YouTube channel since London 2012

Of course they have, and most others are around too. Still a place though for watching things together, and though the BBC showing extensive coverage of London 2012 is unlikely I think sticking the ceremony in the Grandstand slot one weekend would not be a bad idea at all. Maybe hold it back though until when the Olympics themselves should have been airing.

BBC Sport NI on Facebook doing a live stream tonight of Northern Ireland 1-0 win over England in 2005 aka David Healy finest hour in a green shirt. Slightly surprised they could do this as Sky have the rights now but well done to the BBC for this.

RTÉ's Peter Collins has done a write-up yesterday on the Formula 1 Championship which detailed RTÉ's coverage in the past.

I suspect on selling rights might happen now just to take in some extra revenue where they can.

For a laugh bought next weeks TV guide - they didn't even try other than for Sky Sports this weekend - just a blank page saying no schedules available.

The halychon days of the Two Eddies. You’d think that nobody else partook in the World Championship other than Irvine and whatever two drivers happened to be driving for Jordan at that point. Of course there was always the BBC/ITV and Murray Walker. These days of course there is no Irish broadcaster, eir Sport having lost the rights once Sky got them exclusively.

New stuff on BT Sport this weekend:
tonight at 1930 - Scottish Football Extra From Home
Saturday at 1200 - Early Kick Off (pretty much everyone involved, including the director and vision mixer, are working from home for this one)
Sunday at 1000 - MotoGP The Greatest Race - with some live presentation around some classic races
Sunday at 1430 - Rugby Today

This is a great contest for Andrew Cotter's dogs.

Would be interested to know more about the tech involved for the vision mixer to be at home. How do the latencies affect things?

What matters is that the point at which the cut between the two sources happens with the same frames (not at the same (clock) time)that the vision mixer person sees when they press the button .
So if you label each frame / media unit with its origination time,
And the signal from the vision mixing person to the vision mixer electronics is to “switch between source A frame number x and source B frame y “ not “cut now”
Then at the site the vision mixing box delays the videos so that it can then do that cut .. a bit like a VT edit EDL ...
Ed Calverly had a slide set at this SMPTE meeting
https://www.smpte.org/sections/united-kingdom/events/remote-production-over-ip-networks

The “trick” is at slide architecture 3 .. versus architecture 2
And you can do it with multi stage production ..as the BBC did for Euro 16

The camera to mixer output delay has to be just longer than the time to proxy code, the circuit and decoder to the vision mixing person eyes .. And then the circuit back to the venue ..
But with this time compensated production the cuts happen where the vision mixing person saw it happen..... or the commentator saw it and spoke
Sadly Suitcase tv went into administration ,
IPhrame was a very good product ...

Or you pay for full bandwidth circuits like the EPL/ IMG set up !
