AsiaSat Proprietary & Confidential UHD with AsiaSat 16 UHD Challenges
UHD Standards => high throughput requirement! • Much more details (High Resolution & High Colour Space) • Much better viewing experience (High Frame Rate & High DR) Cost of making the UHD content, expensive! • Limited UHD studios available • UHD recording equipment, most are up to p25 only • Editing at p50 or p60 takes a long time Evolution of SDI • UHD-SDI, Electrical or Optical Physical Layer? UHD storage file format is to be finalized with HEVC enable • The industry has not yet fixed the UHD source file format • Aim at reducing storage size • Existing formats are all in MPEG-4 compression – Apple ProRes 50mins UHD p60 clip need 700GB storage! (14GB/min) Spectrum/Bandwidth limited in Terrestrial / Satellite • Occupied by mobile applications
AsiaSat Proprietary & Confidential UHD with AsiaSat 17 Studio Interconnection Standards End to End UHD • HD p50 needs 3Gbps • 3G-SDI cable support up to 3Gbps • UHD 1 p60 needs 10.5 Gbps, What needs to be upgraded • 4x 3G-SDI for UHD 1 at p60 • UHD 2 will need multiple 10 Gbps or over besides the TV set? 100 Gbps • Change of Physical Layer for UHD? Studio Electrical (Coaxial or Ethernet) or Optical (Multimode Fibre)
Compression Workflows Codec
Transitional workflows • UHD & 4K production formats Video and Audio Codec (ProRes, DPX, XAVC, etc.). Development • Needs to support existing HD • The higher bitrate of and UHD post production UHD TV development workflows and conversion. needs increased • UHD Recording equipment Broadcast performance from Domestic standards Codecs and Domestic interconnection compression algorithms standards Spectrum • HDMI (ver. 1.4) => 4K p30 • HDMI (ver. 2.0) => UHD 1 p60 Broadcast standards • UHD for Satellite, Cable, Terrestrial transmission and Internet connections. Spectrum • Spectrum is limited in Terrestrial / Satellite
