  1. <Asia Media Summit 2011> Delivery of 3DTV on Terrestrial Platform : The Korean Initiative 24 May 2011 Sanggil Lee, Ph.D Korea

  2. Current state of 3DTV service in Korea Terrestrial broadcasters, led by KBS, performing experi- mental 3DTV service since Jun. 2010 Satellite broadcaster, Skylife, started real-time 3D Service in Jan. 2010 Cable broadcasters started 3D VOD service in Jul. 2010 Consumer electronics companies, LG and Samsung, the global market leaders of 3DTV Terrestrial 3DTV broadcasting service being standardized

  3. History of KBS preparation for 3DTV service Shown at INPUT 2011 (Seoul, 9~12 May) 3D contents in 2010 R&D started in 2002 Experiments on 3DTV broadcasting in 2010 New 3DTV camera rig in 2011 3DTV camera rig in 2004 Exhibition hall in 2005

  4. 3DTV camera rig developed in 2004 KBS Technical Research Institute

  5. 3D contents produced by KBS

  6. New 3DTV camera rig developed by KBS Left eye camera Right eye camera KBS Technical Research Institute

  7. Methods for 3DTV broadcasting in Korea • Service compatible • (Terrestrial) LegacyDTV (side by side) 3DTV 3DTV LegacyDTV (full-HD) Frame compatible (Cable, Satellite)

  8. Frame compatible 3DTV broadcasting Horizontally half resolution(side by side) Not backward compatible with the legacy DTV system Left image, full-HD Mux MPEG-2 encoder Side by side 3D camera Right image, full-HD TerrestrialDTV broadcasting channel 3DTV LegacyDTV (2D)

  9. Service compatible 3DTV broadcasting Full-HD resolution Backward compatible with the legacy DTV system Left image, full-HD MPEG-2/H.264 encoder Mux Left image : MPEG-2 compression Right image : H.264 compression 3D camera Right image, full-HD TerrestrialDTV broadcasting channel 3DTV LegacyDTV (2D) traditionalDTV (2D)

  10. Terrestrial side by side 3DTV broadcasting (1) 3DTV Legacy DTV • An athletic game broadcasted by KBS on channel 66 • The 6th Colorful Daegu Pre-Championships meeting in May 2010 • Other 3D programs including World cup soccer games aired on the trial basis in May~July 2010 • Frame compatible broadcasting • Horizontally half resolution and not compatible with the legacy DTV system • Encoding and transmission, the same format with the existing DTV

  11. Terrestrial side by side 3DTV broadcasting(2)

  12. Terrestrial full-HD 3DTV broadcasting • Demonstrated at G20 Summit Meeting on channel 66 in Nov. 2010 • Service compatible broadcasting • - Full resolution and compatible with the existing DTV service • Encoded with MPEG-2(left , 12Mbps) and H.264(right, 5Mbps) 3DTV Legacy DTV

  13. Subjective evaluation for 3DTV watching * Surveyed by RAPA(Korea Radio Promotion Association) in 2010

  14. To be considered for 3DTV service The producers as well as the camera men and the engineers should understand the technical principle of 3DTV and 3D feeling for better production. Standardization Backward compatibility with the existing DTV service Human factors Protecting the degradation of image quality Channel frequency for terrestrial 3DTV service

  15. Plan for terrestrial 3DTV broadcasting • Standardization of terrestrial 3DTV completed in Jun. 2011 • Broadcasting of IAAF World Championships in Athletics • Full-HD 3DTV broadcasting compatible with the legacy DTV in Aug. 2011 • Dual streams(MPEG-2 for left video, H.264 for right video) • Plan and Vision • Terrestrial full-HD 3DTV broadcasting service in 2013 • 3DTV without glasses in 2015 • Ultra HD 3DTV trial broadcasting in 2017 • Holographic TV in 2020

  16. Various KBS services - Korea’s leading public broadcaster - TV Radio 1 Radio Radio 2 Radio 3 DMB Internet Smart TV/Phone
