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

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

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

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

5 5 3D contents produced by KBS

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

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

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

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

10 10 Terrestrial side by side 3DTV broadcasting (1)  An athletic game broadcasted by KBS on channel 66 The 6 th 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 3DTV Legacy DTV

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

12 12 Terrestrial full-HD 3DTV broadcasting  Demonstrated at G20 Summit Meeting on channel 66 in Nov  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 13 Subjective evaluation for 3DTV watching * Surveyed by RAPA(Korea Radio Promotion Association) in 2010

14 14 To be considered for 3DTV service  Standardization  Backward compatibility with the existing DTV service  Human factors  Protecting the degradation of image quality  Channel frequency for terrestrial 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.

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

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

17 17 Thank you!
