Just found this thread as I have been a little busy at the Games. As per the original poster,
nlagalle, I am working for the media in London but for the host broadcaster, Olympic Broadcast Services (OBS), so my role is somewhat different and I do not get to any of the venues or see any events, except on TV. Mind you, I do get to see every event as all signals come through the area I work in. As this is my 9th Olympics, I was fortunate to come from MEL on SQ in J but not until a few days before the Games with a couple of days to rest in SIN on the way. I came up from MEL on SQ 238 and then to LHR on SQ308 which conveniently arrives mid- afternoon.
I enjoyed the SQ service that is really special on their longest flights as has been covered by others on numerous threads. I do not mind the day flight and can usually get a little sleep as well as enjoying the personal service and the IFE on SQ's second oldest 380 but one that is still in excellent condition, unlike some of their 777ERs that are showing their age (already).
The accreditation validation, immigration and luggage collection was the quickest I have ever encountered at LHR so I was on the Heathrow Express within 25mins to Paddington but had a slow ride to my accommodation right next to the Olympic Park at Stratford. Here is a genuine view from my hotel room at the Staybridge Suites above the Holiday Inn at Westfield Stratford - sorry to all of you travelling miles everyday to get to the events. I get a good 20 min work to work early in the morning and a 30 min walk back amongst the crowds each night.
I had a senior role with the Host Broadcaster in both Sydney in 2000 and then spent 4 years in Beijing for the Games in 2008 but this time I am employed for only 3 weeks monitoring all the feeds in an area called Production Quality Control (PQC). Even if you are watching the coverage on NINE, FOXTEL, the BBC or NBC, you will be watching the basic host broadcaster pictures from OBS except for any broadcaster's add-on cameras in the studio, in commentary positions or in the 'Mixed Zone' for the after event interviews. NBC will add a lot more cameras to cover their athletes and NINE may have individual cameras at a few venues to cover the Australians but if you have just watched Anna Meares win gold all that coverage will have come from the HB (Host Broadcaster) with Phil Liggett adding his commentary track-side.
To give you some idea of the scale of the event, OBS produces 5600 hours of coverage with over 100 individual HD and 3D feeds from every sport including 91 cameras just at the main stadium and 1000 cameras overall. There are 1275 commentary positions at the venues and a 24/7 Olympic News Service amongst the other services provided to 147 broadcasters who own the rights to the Olympics. Some of these have no presence in London at all - they take the 10 HD 'channels' (similar to the FOXTEL offering) available around the world and containing every gold medal performance. FOXTEL are doing their own packaging in London.
These pictures (taken in very low light) will give you an idea of the area where all the signals are managed.


We work long hours in PQC monitoring all these feeds to ensure that nothing is missed by the producers and directors who come from all over the world to originate the HB coverage. An Aussie crew always cover all the Aquatics (Swimming, Diving, Water Polo and Sync Swimming) with a crew from Finland and Sweden doing the Athletics and a crew from CCTV in China providing the host broadcast of all Gymnastics. If you want to watch 5 feeds of every minute of Fencing a Hungarian crew have provided that coverage.
The production plan is rather conservative and concentrates on unbiased television so all athletes are treated equally while they are competing but then we celebrate with the winners - the victory ceremonies always look the same no matter the venue, for instance - so that commentators at the venue or in their home country know what to expect. You would be unhappy if you did not see the Aussies over the line in the Triathlon even if they were down the field and did not win medals. We do not get it right all the time but in London, like Sydney, the broadcasters have generally been happy.
We are ready to handle any weather delays, late changes to the complicated schedule or any 'incidents' or failures that happen at the venues.
Although I have not been to any venue, I do get the impression that the atmosphere is much the same as in Sydney - everyone is having a good time and not getting too worried about the crowds or the long wait for the trains. It really helps that the Poms are winning more than even they expected. I am getting heaps from my English colleagues in PQC.
I hope thus gives you a little flavour of the resources needed to bring the Games to you at home or watching in some airline lounge somewhere in the world.
