Friday I saw a demonstration of a 4k HD video. 4K means four times High Definition quality, that’s 4096×2160 pixels per image, as I was told that’s around 30 MB per frame! It was a really cool and impressive experience. One of the movies we saw was recorded in downtown Amsterdam, with the beautiful buildings and canals. The quality was really breathtaking! Later on we saw an opera and I really felt if I was watching this live, as if I was physically there, because of all the incredible details!
A film crew of the Research Institute for Digital Media and Content of the Keio University (Tokyo, Japan) has recorded video of the opera “Era la Notte” on Thursday. This was streamed over the SURFnet6 and NetherLight network live to different locations in the world, such as San Diego, Seattle, Chicago, Prague, Barcelona and Sweden. This was a compressed stream, which is just under a gigabit per second. Yesterday there was an uncompressed 4K HD TV stream between Amsterdam and Tokyo. This stream is about 6,7Gbps and was transported over a 10Gbps lightpath between Amsterdam and Tokyo! Try to imagine, that’s more then one data CD per second, or one DVD every 5 seconds! Imagine watching a movie and changing the DVD every few seconds The video was stored at a storage cluster at SARA and the University of Amsterdam, all together 20 TeraByte (20.000 GigaByte) was used to store the video! The video was shot with a special 4K camera; there are just 4 of these cameras in the world!
All together a project like this, with specialist from all over the world and from different fields, such as multimedia, storage and networking is great to experience ! And I am sure I will miss these kinds of projects.
