IBC’14 Update
UHD-1 Phase1 is ready to be commercialized
Little interest from European broadcasters, who prefer 1080p50
Olympic 2016 will be the ground play for UHD-1 Phase 1
UHD-1 Phase 2 is where industry sees value : HDR, HFR, Object audio,…
Heavy meetings to come at DVB, EBU, SMPTE, expect more clarity in 2015
UHD-2 (100M+/s) is for Japan only as not economical before 2020+
2020 Olympics will see UHD1 phase 2 (4K) and UHD-2 (8K)
Harmonic will work with broadcasters, operators, partners to make UHD a
success

Conclusions
Ultra HD is a complex and new eco system
Multiple ways (VOD/Linear/Live) to deliver Video to UHD
screens
1080p60 is a good comprise for Live until UHDp60 10
comes to life
IBC ’14 is the first public demonstration of consumer
grade Live UHDp60 10 (STB, HDMI 2.0)
Ultra HD Live & silicon available now, 2015 deployments
We need standards (HDR, Audio, Security) to mass
deploy Ultra HD
