20. 20 Ultra HD QUALITY FACTORS TO CONSIDER

21. 21 Ultra HD QUALITY VISUAL FACTORS TO CONSIDER • From More Pixels to Better Pixels!

22. 22 HIGHER DEFINITION • Larger Pixel Count is fundamental for 4/8K Display • 8K Display Development History (Liquid Crystal On silicon) (Liquid Crystal Display) (Plasma Display Panel) (Organic Light-Emitting Diode)

23. 23 HIGHER FRAME RATE (HFR) • Improves the Motion Portrayal of Display System • Determined by the balance between the improvement in picture and the difficulty in increasing bandwidth • Gain consensus worldwide in order to reduce motion blur by shortening the duty time @ the display without flicker artifacts • Proposed Frame rate is 120fps

24. 24 WIDE COLOR GAMUT (WCG) Source : Implications of High Dynamic Range on the Broadcast Chain for HD and Ultra-HD Content, Lukasz Litwic, Olie Baumann, Matthew S. Goldman, Philip White, 2015 NAB BEC Limited Dynamic Range for TV Compared to Film Ultra HD to close gap by Higher Bit Depth

25. 25 HIGH DYNAMIC RANGE (HDR) • Dynamic Range represents Luminance Level • HVS has a significantly larger dynamic range • Achieved by extending the range both towards darker as well as lighter values as a result of fitting a conventional Display with a spatially varying backlight

26. 26 HIGH DYNAMIC RANGE (HDR)… Source : Implications of High Dynamic Range on the Broadcast Chain for HD and Ultra-HD Content, Lukasz Litwic, Olie Baumann, Matthew S. Goldman, Philip White, 2015 NAB BEC Pixel Luminance Histogram

28. 28 FLEXIBLE DISPLAYS • Larger Screens on the Order of Displays • Development proceeding on thin and light sheet displays • Organic Light-Emitting Diodes(OLEDs) negative for Backlighting and thin displays • Flexible active-matrix OLED (AMOLED) displays used to design Ultra HD 4K/8K Displays – Ranging from 8 to 18 inches have been developed – Use plastic substrates and are still small to medium sized 13.5-inch diagonal 4K flexible AMOLED display

29. 29 8K SUPER HI-VISION (SHV) • 8K SHV has been developed as the next-generation television of current HDTV to provide the viewers a superior sensation of reality • Japan aims to conduct trial broadcasting in 2016 and start a broadcast service in 2018

30. 30 8K SHV SYSTEM – VIDEO PARAMETERS

31. 31 ULTRA HD SOUND SYSTEM

32. 32 UHDTV SOUND SYSTEM • 22.2 Multichannel Sound – Channel based audio system comprising three vertical layers:  Top layer with 9 channels  Middle layer with 10 channels  Bottom layer with 3 channels  2 channels for low-frequency effects – NHK (Nippon Hōsō Kyōkai - Japan Broadcasting Corporation) has developed 22.2 channel audio system for  Program Production  Transmission  Reproduction System

33. 33 UHDTV SOUND SYSTEM… • 22.2 Multichannel Sound – 24 channels distributed in three layers and its audio channel mapping are standardized in ITU-R Recommendation BS.2051 (2014), and also in SMPTE and ISO/IEC

41. 41 MEDIA DELIVERY SYSTEM : SMT Smart Media Transport Presentation Engine NGB IP Broadband  Network convergence  IP based for broadcasting  Traffic sharing cooperative network  Push and pull combined delivery

42. 42 8K SATELLITE BROADCASTING • Every part of the ecosystem from production at a studio or in the field to reception at home has to be complete and connected to each other before starting an 8K satellite broadcast • Various technologies and broadcast standards have to be developed • Standardization process has been ongoing at the Association of Radio Industries and Businesses (ARIB) in conformance with the report of the Telecommunications Council, Japan

43. 43 8K SATELLITE BROADCASTING… • Satellite Transmission – Difficult to assign a new spectrum band to a new service owing to the extremely high demand for spectrum from various industries – Use of the current band for broadcasting is also beneficial for the rapid proliferation of a service to homes – Roadmap described in the previous section specifies a 12- GHz-band satellite as one of the main transmission paths for 4K and 8K broadcasting – Transmission system for advanced wideband digital satellite broadcasting, which was standardized at ARIB, has been recently revised to be compliant with the specifications – Transmission capacity of 100 Mbps was achieved with 16 APSK, an LDPC coding rate of 7/9, and a roll-off of 0.03 Satellite transmission van used in the test (Jan. 28, 2014)

44. 44 8K SATELLITE BROADCASTING… • Video Source Coding – Compression for a video source signal is vital for a broadcast service that uses a limited bandwidth – Technology advances in each generation, and the newest one is H.265/HEVC, which was standardized in 2013 – Real-Time 8K encoder compliant with this standard was developed by NHK – Picture-quality assessment concluded that a bit rate of 80 to 100 Mbps is required for 8K/60P – ARIB standard was revised to use H.265/HEVC H.265/HEVC real-time encoder for 8K

45. 45 8K SATELLITE BROADCASTING… • Interface for Content Production – Interface is indispensable for the construction of a production system – Extensive efforts are being made to develop a UHDTV interface having a similar role to that of an HD-SDI in an HDTV system – An interface based on 10Gbps multifiber optics technology was standardized at ARIB – Production equipment such as a camera, recorder, and display has been developed – The connector and cable used are similar to those of an HD-SDI and widespread use is – expected with cost reduction – Interface is called “U-SDI” and is under standardization at ITU-R and SMPTE globally (a) an optical cable for the new interface and (b) a conventional coaxial cable

46. 46 UHDTV BROADCASTING SYSTEM SPECIFICATION • Technical specifications for UHDTV broadcasting systems in Japan

47. 47 ULTRA HD STANDARDIZATION

48. 48 UHD STANDARDIZATION • What about compression? – HEVC (H.265 and MPEG H Part 2):High Efficiency Video Coding – Version 1(Jan 2013): Main and Main 10(8-10bits, 4:2:0) – Version 2(July 2014): Range Extensions (≥10bits, 4:X:X) + Scalabilities – On going: MPEG XYZ, HDR working group (CFE July 2015) • What about Signalization/transport? – MPEG-2 TS, MPEG-DASH, .mp4 – MMT (MPEG Media Transport)? HLS? – SMPTE : 6G/12G SDI ?, Video Over IP (SMPTE 2022) ? – HDMI 2.0 : supports up to 4kp60 • What about Application standards? – ARIB B-32, DVB (UHD Phase1) – SCTE, ATSC 3.0 • What about Audio? – Nothing new for phase 1 – Audio 3D/Object / Spatialization => MPEG-H part 3, AC4

49. 49 UHD STANDARDIZATION… • Standardization bodies are working on defining what UHD is: – ISO/ITU : Format, Compression and Transport – SMPTE & HDMI : Baseband transport – DVB, ARIB, SCTE, ATSC : End-to-End Solutions

50. 50 UHD STANDARDIZATION… • Phase 1 standardization (almost) finished – 3840x2160@60fps max – 4:2:0, 8–10 bits – Rec 709 (BT2020 optional and discouraged) – Video codec is HEVC Main and Main 10 – Audio: current toolbox • Phase 2 will address – 3840x2160p – Up to 4:2:2 and 4:4:4 – Higher frame-rates (i.e. 100/120Hz) – Wider Color Gamut (i.e. BT2020 or subset) – High Dynamic Range – Scalable Video Codec, HEVC – Audio: beyond 5.1, 3D Audio
