Ultra High Definition TV (Ultra HDTV) will offer (*)
• Higher resolution
• Higher frame rate(s)
• More colours
• Higher Dynamic Range (HDR)
• Immersive audio

ULTRA HDTV IN A NUTSHELL (2)
High Definition and Ultra High definition …
High Definition (HD) HDTV (ITU-R BT.709)
− Up to 2.1 Mpixels per frame (1920 pixels x 1080 lines)
− Frame rate: 25 or 30 fps (frames per second or Hz)– May be 50 / 60 fps (3G) in the future
− Colour depth : 8 bits (16.7 Mcolours) in DTH (Direct To Home), 10 bits in contribution (1 Billion)
Ultra HDTV : 2 formats defined by ITU* (ITU-R BT.2020)
− UHDTV1 (“4k TV”) : 3840 x 2160 pixels = 8.3 Mpixels
− UHDTV2 (“8kTV” / Super Hi-Vision by NHK): 7680 x 4320 pixels = 33.2 Mpixels
Note: Quad HD = « Temporary » Ultra HD format based on BT.709
*ITU = International Telecommunication Union

ULTRA HDTV IN A NUTSHELL (3)
Ultra HDTV should also offer:
Progressive mode (instead of interleaved)
Frames rates:
− The experts recommend 50 / 60 fps as a minimum for UHDTV1 (Phase 1)
− Higher frame rates later on (100 / 120 fps): Phase 2 of UHDTV1 + UHDTV2 (Super Hi-Vision)
Colour depth: 10 bits (1 billion colours) or 12 bits (68.7 billion colours)
Colour gamut : considerably increased (see slide 6)
− More colours and more nuances
High Dynamic Range (also possible with HD): greater dynamic range of luminosity
Immersive audio later on

UHDTV 1 (4k TV): 2 phases are envisaged by DVB
(tentative)
Phase 1: up to 50 / 60 fps (colour space: BT 709, or : BT 2020)
Phase 2: 100 / 120 fps (BT 2020)
Then UHDTV2 (8k TV)

CALENDAR (3)

Encoding / compression:
MPEG-4: good efficiency with progressive mode, but industry is now focused on a new standard: HEVC (High Efficiency Video Coding)
HEVC: − should be 30 to 50% better than MPEG-4 (H264/AVC) − can be applied to all formats: HD, Ultra HD
Ultra HD needs HEVC to take off…
Connectivity:
HDMI 2.0 connectors
4k Blu-ray players + Game stations: 2015
4k UHD TV set: HDMI 2.0: 2014 (50/60fps)
(Some with embedded HEVC decoder)
4k Satellite Set Top Box With HEVC: 2015
CALENDAR (4): UHDTV1 (4K TV) GLOBAL DISTRIBUTION + HOME

4k camcorders : • Consumer : end 2014 • “Prosumer”: end 2014
Some 2014 TV sets can be directly connected
to the satellite dish ! (Embedded DVB-S2 demodulator
and HEVC decoder) 2015

4k via fiber: same time as via satellite, but not
everywhere
4k via DTT: not before 2015 with DVB-T2 & HEVC, and not everywhere
2015
4k via ADSL : with HEVC, but not everywhere
New boxes for 4k TV

Over 800 Ultra HD channels within the next
10 years predicted with a CAGR of almost 50%*
Growth mainly driven by North America (40%),
Asia (17%) and Western Europe (14%)
HTS will support roll-out in selected
regions, notably in North America and Western Europe

With almost 70% of channels distributed
via DTH platforms, satellite will drive Ultra HD roll-out*
For 2015, already 12
UltraHD channels are expected
About 60% of channels broadcast via satellite
will be from North America, Western Europe and East Asia
