There was a lot of buzz around 4K TV, also known as Ultra High Definition Television (UHDTV), during the IBC 2013 tradeshow. We interviewed Cristiano Benzi, Eutelsat’s Director of the Business Unit Video and Broadcasting, at the Eutelsat stand on the set-up of the 4K demo with live images from the Misano Circuit in Italy, where the Motor GP took place during IBC.
This live demo of an end-to-end satellite based delivery chain for contribution of live images in 4K using a conventional SNG van was a joint operation between Ericsson, Eutelsat Communications, Globecast, Newtec and Sky Italia.
The 4K feed was produced by Sky Italia in 3480x2160 at 60p using different camera brands and video mixers.
The live sequences from the mixers were said to then be delivered in the form of a quadruple 3G-SDI signal to Ericsson’s content acquisition platform. Using Ericsson AVP 2000 Contribution Encoders to provide 4K contribution feeds, the signal was compressed in MPEG-4 AVC at 60p and 10-bit, 4:2:2 resolution by the Thomson ViBE VS7000.
The signal was then modulated by the Newtec AZ110 satellite modulator, using DVB-S2 16APSK modulation, making 89 Mbps of throughput available over a conventional 36 MHz Ku transponder on board the Eutelsat 5 West A satellite located at 5° West. The satellite uplink was performed and monitored by Globecast from one of its HD SNG trucks, equipped with a 1.4-meter antenna and 400 W amplifier.
The feed was received by a 2.4 meter antenna and distributed to the Eutelsat stand at the RAI Amsterdam.
