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
