Ultra HD, or UHDTV, is the next generation television standard beyond HDTV and 4K. It provides viewers with a superior sense of reality through higher resolution, higher frame rates, more colors, and higher dynamic range. Key aspects of UHDTV include 8K resolution displays and broadcasting, wide color gamut, high dynamic range, and next-generation 22.2 channel surround sound. Standardization efforts are underway to define UHDTV formats, compression, transport, and end-to-end solutions. Early adopters like Japan and Korea are conducting trials of 8K satellite and terrestrial broadcasting using HEVC video coding and DVB transmission standards.

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

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

– 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

– 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
