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
