On June 25, I witnessed the successful demonstration of a true 4K Ultra High Definition (UHDTV), end-to-end video transmission over satellite to Turner Broadcasting’s facilities in Atlanta.
It’s one of the first transmissions of UHDTV signal over satellite to be tested in North America and the demonstration successfully proved that the satellite delivery chain can accommodate next generation signals as soon as broadcasters are ready to offer them.
The hottest topic in the satellite industry is currently 4K which is fast defining how much space is needed on satellites to cope with the demand for higher resolution content, more color and more pixels on the screen.
The objective of this demonstration was to actually get a TRUE 4K video, live encoded and decoded, in 3840 x 2160, p59.94 4:2:2 10 bits, transmitted over satellite.
We had previously conducted tests with the satellite transmission provider, PSSI Global Services, in preparation for the UHDTV demonstration and achieved 140 Mbps over a 36 MHz transponder on Galaxy 13 to a 4.6-meter antenna.
And for this particular demonstration at Turner, we provided the modulation and demodulation which featured our Clean Channel Technology (CCT). Our CCT is used to extend the current DVB-S2 digital signal transmission standard and implement lower roll-off and boost throughout capacity. The technology further improves satellite transmission efficiency by up to 15 per cent compared to the current S2 standard for IP trunking, backhauling, government networks and also broadcast contribution.
Intelsat’s Galaxy 13 satellite delivered a 4:2:2 10-bit, 4K UHD signal at 60 frames per second, which resulted in an immersive viewing experience.
The 100 Mbps video feed was encoded and decoded in real time by Ericsson, using its AVP 2000 contribution encoders and RX8200 receivers, capable of 4K UHDTV operations as well as HD and SD contribution at the highest quality.
Shaping the Future of Satellite Communications
As part of the demonstration, Intelsat, Ericsson and Newtec were invited to present in Atlanta at the Society of Motion Picture and Television Engineers (SMPTE), about the importance of 4K with the advent of providing more crisp and detailed images through High Definition into the home.
My presentation in particular addressed how our Clean Channel Technology helped provide a 10% better roll-off, 32.73 Mbaud and delivered throughput pictures exceeding 101 Mbps. And with the introduction of S2 Extensions later this year, the increased granularity, lower roll-off and efficiency gain of up to 37% will provide a better picture transmission.
We are now planning a live demonstraton at the upcoming IBC2013 show in Amsterdam.
