      Sky demonstrates 3D TV for the first time

      3D experience delivered through Sky’s existing Sky+HD infrastructure

      • Sky’s research and development team has successfully demonstrated 3D TV at its West London HQ, becoming the first UK broadcaster to deliver a 3D TV experience to a domestic TV.

      • The content was delivered using Sky’s digital satellite broadcast platform. Playback, via a Hyundai ‘3D Ready’ TV, was direct from the hard drive of a standard Sky+HD set-top box.

      • The 3D content demonstrated included:
      • England vs New Zealand Rugby Union Test Match
      • Liverpool FC vs Marseille UEFA Champions League
      • Sky1’s Gladiators
      • Ricky Hatton vs Juan Lazcano


      • All content was filmed, produced and edited by Sky’s in-house team using Sky’s dedicated 3D TV cameras and rigs.

      • This was not a product launch, purely a technological demonstration of Sky’s ability to satisfy any future demand for 3D service. Sky is currently working with others in the wider TV industry (including TV manufacturers and studios) to help establish the potential for commercial 3D TV services.

      • The demonstration illustrated that Sky’s current Sky+HD infrastructure is ‘3D Ready’

      Gerry O’Sullivan, Sky’s Director of Strategic Product Development, comments:

      “Today’s breakthrough is the latest in a long line of Sky firsts since our launch 20 years ago, including the UK’s first digital TV service, the ground-breaking Sky+ and the introduction of HD. Our R&D activity is all about anticipating customers’ future demands, including the potential to turn HD into 3D.

      “With another first today, we’ve demonstrated that it’s now possible to offer a ”seeing-is-believing” 3D TV experience in the home. And thanks to our high-capacity satellite network and HD boxes, we have shown that Sky+HD is already ‘3D Ready’.”

      SkyUser were invited to the demonstration of this 3D technology, and you can read our review here.

      Further documentation about the process of 3D technology can be found in our article below, 3D TV explained.

      3D TV explained

      How the human eye sees images

      The human eye’s ability to see things with variable depth and wide perspective is based on how the brain processes two separate images, as received by each eye. When someone looks at something the brain is able to merge two separate images together to create a field of vision which is both three-dimensional and allows the viewer to focus on specific areas within any given scene.

      The jump from 2D to 3D

      TV has traditionally only been able to deliver a single image to a television screen. For all the innovation that we’ve seen in TV (including the move to colour, the migration to digital, and more recently, the launch of High Definition services), all of these developments have only been able to work within the parameters of a single incoming TV feed - a 2D experience.

      So even though HD delivers an intensity and richness which results in exceptional clarity and detail, it is still based on the same underlying picture delivery mechanism as previous TV formats.

      3DTV is possible because of a series of major breakthroughs (principally in camera, post-production, encoding, set-top box and TV set technology) which means that domestic TVs are now capable of processing an image in a way that can deliver the depth information to the brain - much like the human eye - and hence add a further dimension to HD.

      For the first time, two images can now be merged and played out simultaneously on the same domestic TV display. Polarising glasses are currently used to help direct the correct left or right full colour on-screen image to the corresponding eye. The brain then processes each feed to create a single image, providing a level of depth and focus which means that the content is able to move to and from the foreground and therefore becomes three-dimensional.

      Why 3D TV is a complex process

      The most difficult part of the 3D TV production process is that two separate images need to be captured absolutely simultaneously. The cameras used are High Definition cameras, but special camera rigs need to hold two cameras in specifically aligned positions. One method uses cameras which sit directly next to one another (with the lenses 6 cm apart, which is about the distance separating a pair of eyes).

      The two different feeds or recordings need to be exactly time-stamped from a single, synchronised clock to ensure that both images can indeed be displayed simultaneously during playback.

      Post-production then requires the two images to be edited so that colours match exactly, and focus and depth are consistent to ensure smooth transitions between scenes, and any small discrepancies of image position and scale are corrected. Depth can also be manually manipulated to enhance or control the resultant 3D experience.

      These techniques help avoid any rapid moves between different depths and focus points, which can cause a feeling of sickness in some viewers.

      Once the captured images have been through the post production cycle, they need to be delivered into the home and onto the TV. This requires significant bandwidth - essentially the equivalent of two HD feeds.

      Sky’s digital satellite network is therefore ideally placed to distribute this content into the home because of its capacity. What’s more, the current generation of sophisticated Sky+HD set-top boxes already have the necessary processing power to be able to both receive the 3D encoded signals, store them and then deliver them to a ‘3D Ready’ TV display. Sky customers would therefore only need to purchase a new 3D ready TV to extend their experience to HD into a further dimension.

      The reason Sky has the potential to deliver a 3D TV experience into the home is because of its investment in HD and the enhancements already made to its infrastructure and network in order to handle high capacity, bandwidth hungry services.

      The Sky+ HD platform currently offers 30 dedicated HD channels and is Europe’s most comprehensive and commercially successful HD service. Due to the massive bandwidth available to the satellite platform, there is still scope for many more HD channel launches, as well as the potential to accommodate whatever may follow.

      What next for Sky and 3D TV?

      For Sky, the next stage in the current R&D process is moving on from understanding whether it’s possible from a technological perspective to deliver a 3D experience into the home to working with the industry and customers to understand whether there is a market demand for it.

      Sky will continue to build up its library of 3D produced content in order to provide a range of content through which testing, evaluations and trialling can take place to ensure service is of the expected quality expected by the consumer. Sky will also continue to work with the rest of the industry, including standards bodies, major content producers and TV equipment manufacturers This will help drive shared standards , working practises and processes so that should there be a demand for 3D, the industry is well placed to deliver against that.
