Olympic Games coverage: HD, robotic cameras and 3D

 
The BBC has unveiled its "Stadium UK" title sequence and marketing campaign for the London 2012 Olympics. The campaign shows the landscape of the United Kingdom transformed into a giant sporting arena inside the Olympic Stadium. The BBC is the official broadcaster of the London 2012 Olympic Games in the UK

Somewhere beneath the streets of London, four miles of fibre optic cables linking the Olympic Park to the BBC's Television Centre lie in darkness.

But when the Olympic opening ceremony starts on 27 July, data will flash through them as they transmit the highest definition pictures Olympic coverage has ever seen.

Technology has come a long way since the last Olympics in London in 1948, broadcast in black and white.

The cables will carry ultra-high definition video, which at a resolution of 7680x4320 is an astonishing 16 times the quality of HD television.

The video technology was developed and supplied by Japanese broadcaster NHK, and is known as Super Hi-Vision.

It will be sent to the world's first ultra-high definition production centre at the BBC, and then over high-speed data networks to four giant screens around Britain, two in Japan and one in the United States.

"When you see this type of ultra-high definition television, it's just like looking though a glass window," said Tim Plyming, the BBC's Super Hi-Vision project leader.

"This is the highest definition that the human eye can understand - it's the end of the story in terms of resolution."

Going 3D

But with only a handful of screens around the world capable of displaying ultra-high definition pictures, an estimated 4.8 billion sports fans will be turning to their televisions, computers, or mobile devices to catch the Olympic action.

London 2012 will be the first Olympics to feature live 3D television broadcasts, and 33 "true 3D" cameras will be used to capture more than 230 hours of 3D coverage.

The BBC will broadcast the opening and closing ceremonies and the men's 100m final in 3D, and pan-European broadcaster Eurosport will also be providing 3D coverage.

The BBC will broadcast more than 2,500 hours (equivalent to almost four months) of high definition television over the 17-day period, covering every sport, from every venue, on every day.

To squeeze it all in, the corporation will use 24 Olympic channels, which will be available via the BBC Red Button or channel numbers in the electronic programme guides on cable and satellite services.

The same 24 television channels will also be available as 24 high definition online streams, tailored for viewing on connected TVs, PCs, tablets and mobile phones, and the BBC expects online viewing figures will be the highest ever.

"For moments involving British athletes, or major games moments, we have planned for a doubling of streaming capacity over the highest we have ever needed before," says Phil Fearnley, BBC Future Media's general manager.

The BBC has recently introduced a new video delivery technology called "chunked streaming " which makes it possible for a viewer joining halfway through an event to "rewind" the stream back to the start.

This technology will feature in the BBC's new Live Interactive Video Player, which is being introduced specially for the Olympics on its website.

It allows visitors to switch between the 24 live streams instantly, rewind to earlier parts of the action, receive alerts about big moments on other channels ("Tom Daley is diving now!"), and access real-time statistics and information about individual athletes or events.

"This is a knockout piece of technology," says Mr Fearnley.

Next-generation video coverage

  • Brings live HD video coverage to the desktop
  • Enables audiences to switch between 24 simultaneous live streams effortlessly
  • Gives the option to rewind live coverage, for audiences who missed the start of the action
  • Provides chapter markers, enabling simple navigation to those key moments within a session (e.g. the gold medal winning dive)
  • Offers relevant live data, statistics and information, while viewers are watching, in a seamless and unobtrusive way
Mobile experience

For mobile users, a mobile site will mirror much of the desktop experience, adapted to the size of their device's screen.

Apple and Android users will also be able to access the 24 live video streams and highlights.

BBC Olympics apps for Apple and Android smartphones will include all the features available on the mobile browser site, plus the ability to read content even when disconnected from the internet.

There is also a BBC Sport app for Virgin Media's TiVo service, Sony, Panasonic and Samsung internet-connected televisions and Sony's PlayStation games console, which allows viewers to watch online streams, on demand highlights and news headlines on their TVs.

Around the globe

The BBC's streams are only available in the United Kingdom, but viewers elsewhere in the world will be turning to other sources of online coverage.

Screengrab of Getty Images Getty Images, the official photo agency of London 2012, expects to shoot more than one million pictures during the Games

In the US, NBC will be adding to its broadcast and cable television coverage with streamed content delivered using technology provided by YouTube, and the International Olympic Committee plans to provide a live stream to sports fans in 64 countries across Africa and Asia using its own dedicated YouTube channel.

No Olympics would be complete without photographic imagery - and Getty Images, the official photographic agency, expects to shoot more than one million pictures during the games.

These will include 3D images - an Olympic first - and high resolution 360 degree panoramic photographs.

Some of London's Olympic venues, including Wembley and Excel, do not provide photographers with ideal vantage points, according to Getty Images' Ken Mainardis.

To get around this problem, Getty is pioneering the use of robotic cameras installed in the roofs of these buildings.

Photographers up to 200m away can see each camera's view on a laptop screen, adjust the camera settings using software running on a laptop, and move the camera and take photographs using a joystick.

Back in 1948, it took hours just to get photographs developed, but Mr Mainardis says fibre optic networks allow the best Olympic pictures to be made available across the globe in minutes.

"From the moment an athlete crosses a finishing line, a photograph will arrive at a newspaper as far away as Australia in about 180 seconds," he says.

    How dare the BBC waste public money on 3D and HD, surely we should learn of these events through the daily press coverage and not rely on whimsical technology to inform the masses!

    Home 3D has moved on. It is now at cinema quality if you can afford the appropriate screen and smart glasses.

    You can always argue that such technology is a waste of time and money. I recall the same arguments about colour TV. However, we would never progress if someone didn't pioneer, at great expense. No doubt 3D will eventually be glasses and headache-free. Ordinary HD will become old hat.

    I watched the Wimbledon final in 3D, broadcast by the BBC. Some absolutely superb camera angles chosen to really show the capabilities of 3D. I'm happy to see that my license fee is being put to good use - by spending on and utilizing new technologies.
    I hope that the BBC will be able to broadcast more 3D content. 3D TV's are now within the price range of almost every household.

    How wonderful that the BBC are spending so much money on this already over budgeted fiasco, especially when they've said they're reducing expenditure on programmes that more people would enjoy.
    As others have mentioned, the ownership of 3D televisions is limited, so only the wealthy will benefit.......nothing new there then, it's par for the course in Britain.

    As one of the majority who tried and failed to get tickets, I'm looking forward to enjoying the games to the max on telly. Thanks to the BBC for maximising my chances of seeing all the best events, even if they happen at the same time. Nice job !
