  • This slide shows the number of pixels of candidates as UHDTV. The UHDTV(8k) has four times more pixels than HDTV, and the UHDTV(4K) has two times more than HDTV, horizontally and vertically. \n \nGenerally, the standard viewing distance of television is defined as the distance which an observer, who has 20/20 vision as visual acuity, is unable to perceive the pixels. For UHDTV, the standard viewing distance is 0.75 to 1.5 times of picture height. 0.75 value is for UHDTV(8K) system. 1.5 value is for UHDTV(4K) system. At this distance, an image on the screen can be viewed at a horizontal angle of about 100 to 60 degrees, which is much wider than that for HDTV. This means that, with UHDTV, we can see images on a much grander scale.\n

  • We staan aan de vooravond van een transformatie die de mediasector fundamenteel gaat veranderen;\nFilmproducenten en televisiemakers werken steeds meer samen in (virtuele) teams; \nDoor CineGrid ontstaan de mogelijkheden voor nieuwe formats en producten en worden nieuwe businessmodellen mogelijk; \nCineGrid brengt wetenschappelijke, economische & creatieve ontwikkeling en gebruik samen;\nLanden en regio’s die erin slagen om deze innovaties sneller om te zetten in mainstream media zullen daar economische vruchten van plukken.\nDoor verbindingen met universiteiten, hogescholen en marktpartijen worden de mediaprofessionals opgeleid met technologie die elders pas over een aantal jaar beschikbaar is. \n\nFrancic or Copola 1981 - looking at Elecronic Cinema\n

  • The winning entries all demonstrated the following qualities:\n•Need for a lot of detail in the image to make use of the high resolution;\n•Capturing moving images, the hallmark of video;\n•The currently used resolution clearly falls short of what is needed.\n\n

    4. 4. CINEGRID• Production, transmission and viewing of soud and video in ultra-high quality using high performance fiber optics• 4K - 1 frame = 4 x HD: 4096 x 2160 pixels• Uncompressed ca. 8 Gbits per second• 5,5 TB for 1 ½ hours of film ~1200 DVD’s And: A worldwide community of scientists, technicians and audiovisual artists that invent and shape a new promissingmedium
    5. 5. WHY IS MORE RESOLUTION BETTER? 1. More Resolution Allows Closer Viewing of Larger Image 2. Closer Viewing of Larger Image Increases Viewing Angle Visual acuity=1.0=20/20 3. Increased Viewing Angle Produces Stronger Emotional Response Standard viewing distance 1920 1080 HDTV (2K) 30º UHDTV(8K) 24 Gb/s 7680 3.0 × Picture Height SHD (4K) 3840 4320 2160 7.6 Gb/s 0.75 × Picture Height 100º 60ºYutaka TANAKASHARP CORPORATIONAdvanced Image Research Laboratories 1.5 × Picture Height

    13. 13. CINEGRID GOALS• Feature Films (live action / animation)• Educational Usage• Scientific Visualization• Extremely HQ Videoconferencing• Reproduction of Performances• Gaming• Television
    14. 14. EDUCATIONAL CHALLENGE• 2010 4K Contest by SURFNet and Waag Society• Goals: first educational applications of 4K content• 12 entries• 5 winners• Prize: – access to 4K production set – technical & artistic assistance – 5K in cash for out-of-pocket cost• Target group: Higher Education Audiovisual Centers
    15. 15. WINNERS• Larger than Live: Research into the impact of high image quality on viewers• Enhancing the safety of bike lanes, using 4K video of people navigating an unknown terrain• Teaching how to use Geographic Information System (GIS) data, using the high resolution of the 4K screen• Classroom based training with 4K-microscopy imagery, using the 4K screen to make both details and larger context of biological preparations visible• Research into resolution, perception and information overload, by filming a complicated scene that puts high demands on the viewer
    16. 16. LARGER THAN LIVEFree University of Amsterdam
    17. 17. FIRST FINDINGS (LARGER THAN LIVE)• The filmed 4K material was just about 25 minutes. However, this lead to 1,5 TB of video material. As a result, render and copy times soar and can amount to nights and days;• 4K cameras have a low dept-of-field. This can be used for artistic purposes but can be a nuisance in low light conditions;• It is not possible to see the full resolution of the recording on the set. Currently the 4K result can be viewed after post-production only.• COOKBOOK http://www2.surfnet.nl/publicaties/cookbook4k.pdf
    18. 18. FURTHER DIRECTIONS• Medical applications, eg. by extending 4K cameras with a catheter;• Social research, eg. analyzing classroom situations or studying the use of space and behavior;• Capturing performance art, like theater and dance from the perspective of the viewer;• Scientific visualization where lots of data have to be judged in parallel, eg. in climate studies, biology, chemistry, physics and astronomy;• Videoconferencing and collaboration, especially in many-to-many settings.
    19. 19. CHALLENGES• Expensive hardware requirements: cameras, screens, computers, encoders, decoders and projectors;• Infrastructure for storing and editing is complex and often inaccessible;• Current lack of an experienced community of like- minded but multidisciplinary practitioners;• Currently there is no commercial way to use 4K in real-time.
    20. 20. CINEGRID IN THE NETHERLANDS• Testbed for viewing, production and transport of 4K material – Digital projection and sound of very high quality – Editing and capture facilities – Rendering & disk space – Extremely high quality networks• In the center of Amsterdam• Experimental & business use• International networks• Maximum spin-off
