Demonstration showcases advanced ultra-high definition television technology across international research networks
12 September 2011 Pioneering technology which delivers pictures 16 times sharper than standard High Definition (HD), powered by advanced research networks, has today been demonstrated at the IBC broadcast show in Amsterdam.
The Super Hi-Vision (SHV) project
, originally developed by NHK in Japan, showed pictures transmitted from the BBC in London across the high capacity JANET
, GÉANT and SURFnet
research networks. This on-going demonstration (on stand 8.G01) both proved the technical feasibility of SHV technology and was part of preparations for the London 2012 Olympics. Olympic Broadcasting Services (OBS), NHK and the BBC are planning to provide public viewing of SHV at next year’s London Olympic Games.
The ultra- high quality of SHV content means that it needs high capacity, secure, stable, high speed networks to transmit pictures and sound. Consequently the project involves advanced research networks in participating countries as only they provide the combination of speed and reliability to carry pictures without losing definition or forcing up costs. During this demonstration pictures from the BBC in London travelled across JANET, the UK’s National Research and Education Network (NREN) via the pan-European GÉANT network to the Netherlands, where the Dutch SURFnet network delivered them to the IBC conference centre in Amsterdam, through a KPN dark fibre.
The on-going development of SHV and the IBC demonstration involves a closely integrated group of project partners. As well as NHK (the original developers of the technology), the BBC, GÉANT, JANET and SURFnet, Internet2 - the US academic network and the Japanese telecoms company NTT with its GEMNet2 network test bed are key project members. At IBC a separate demonstration linked Amsterdam to Japan via Internet2 in the USA to show the advanced, real-time monitoring and management capabilities developed for the project by NTT to guarantee secure, seamless transmission of content.
At IBC the project showed live video streamed from London, along with pre-recorded SHV film of the last NASA space shuttle launch and content explaining SHV and how it works.
The Super Hi-Vision system is the world’s first video system with 4000 scanning lines. It uses a video format with 7680 x 4320 pixels (16 times higher than standard HDTV), backed up by 22.2 multichannel sound to deliver ultra-clear, realistic three-dimensional images so real that viewers feel as if they were actually there.For more information, see: Super Hi-Vision Project
