ULTRA HDTV IN A NUTSHELL (1)
Ultra High Definition TV
(Ultra HDTV) will offer
(*)
• Higher resolution
• Higher frame rate(s)
• More colours
• Higher Dynamic
Range (HDR)
• Immersive audio
(*) With respect to High Definition

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 4
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

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
