Era 4K sudah mulai digaungkan.. mari kita mulai perbincangannya, tentang segala yg meliputi perkembangan tekhnologi 4K ini.
Ultra HD, the next viewing revolution.. Revolusi baru dalam menonton..
Ultra high definition television (also known as Ultra HD television, UltraHD, UHDTV, or UHD) includes 4K UHD (2160p) and 8K UHD (4320p), which are two digital video formats proposed by NHK Science & Technology Research Laboratories and defined and approved by the International Telecommunication Union (ITU).
The Consumer Electronics Association announced on October 17, 2012, that "Ultra High-Definition", or "Ultra HD", would be used for displays that have an aspect ratio of at least 16:9 and at least one digital input capable of carrying and presenting native video at a minimum resolution of 3840×2160 pixels.http://en.m.wikipedia.org/wiki/Ultra_high_definition_television
Eutelsat extends Ultra HD reach to Asia with the first 4k TV channel introduction with ST Teleport
Singapore, 13 June 2014,
Extending its expertise in Ultra HD to Asia, Eutelsat Communications (NYSE Euronext Paris: ETL), working in partnership with ST Teleport, one of Asia's leading full-service satellite, fibre and IP communications solutions providers, will be introducing its 4k TV channel on the EUTELSAT 70B satellite that reaches across Southeast Asia and Australia.
The content displayed by Eutelsat’s new 4k channel is encoded in HEVC by ATEME and Thomson Video Networks at 50 frames per second with 10-bit colour depth (one billion colours – HEVC Main 10 profile). It will be displayed on the Eutelsat stand at CommunicAsia 2014 using a Samsung 65 inch panel (UE65HU7500) and can be received directly by the latest consumer 4k TV panels equipped with DVB-S2 demodulators and HEVC decoders.
The 4k TV channel is broadcasting a growing library of documentary, cultural and sports content filmed by television channels, production companies and Eutelsat to showcase the stunning viewing experience of Ultra HD.

Live DVB-S2 and DVB-T2 transmission on show at ABU DBS in KL
KUALA LUMPUR, Malaysia — A live demonstration of a unique satellite and terrestrial hybrid 4K transmission system is in the works for the upcoming ABU DBS (Digital Broadcasting Symposium) 2014 Exhibition in Hotel Istana, Kuala Lumpur, Malaysia.
For the demonstration, Village Island and Aviindos developed with MEASAT the idea to empower the live transmission through a DVB-S2 transponder. This follows a request from the DVB group to demonstrate dual 4K services on a single DVB-T2 channel. The demonstration is also in response to generic deployment trends in South-East Asia to deploy digital TV concurrently via satellite and terrestrial means.
“The DVB-T2 deployment of a country is a step by step process which can last several years and some region with low density of population may be very late to receive the DVB-T2 stream. Only the combination with satellite can permit a complete and fair coverage of the overall country. We see it as a common requirement through the Digital TV deployment process to offer identical signals over terrestrial and satellite. The Satellite also offers the advantage to distribute synchronously the broadcast feed to hugely distanced terrestrial transmitters. We even start to see digital TV STB (Set-Top-Box) with hybrid DVB-S2 and DVB-T2 tuners”, says Jonathan Triboulet, Sales Director at Village Island Asia.
“As part of our goal to offer a viable total solution to our customers and partners, we are taking this opportunity to showcase the ideas that has been deemed conceptual. For that purpose, we are very happy to partner with such a great names as MEASAT for real DVB-S2 satellite transmission and Total Communication for on-site 3m width downlink antenna setup to feed Village Island/Aviindos DBS booth (#59-60) and also the DVB Workshop area with the live carrier signal. Also, to monitor the carrier reception quality and continuity, a live carrier monitoring system “Decimator D3″ from SED Systems Canada will be setup on-site for the 4 day event.” says Naveendran Murthy, Sales Director, Aviindos.
“For such advanced 4K reception, we are glad to provide the Village Island “VH-4000″ real-time HEVC decoder and display two 4K videos on advanced 4K display such as the SONY 65″ KDL-65X9004A. The 4K video will also be viewed on MEASAT booth using Sony 55″ KDL-55X9004A, as we transported the base-band 4K signal over fiber thanks to the unequalled BarnFind synchronous SDI transmission technology. The DVB-T2 modulation and demodulation is empowered by DekTec unique technology. For instance, DekTec’s T2Xpert enables DVB-T2 detailed parameter analysis while achieving PLP forwarding over IP.” says Michael Van Dorpe, President of Village Island. He adds: “Please attend our DVB Workshop for more explanation on this topic”. (Workshop11/Session 4: “Future of TV Content” at 9:00 am – 10:30, on the 6 March 2014 at SAFIR II room at ABU@Hotel Istana)
“MEASAT is excited to once again be part of an industry first, that is to support, at ABU DBS, the first ever live over satellite 4K Trials using HEVC. These trials demonstrate MEASAT’s drive to be at the forefront of new, innovative satellite services, as we work hand-in-hand with our partners to take technology from concept to application and then to businesses and the consumer,” said Raj Malik, Senior Vice President – Sales and Marketing, MEASAT.
“The satellite connectivity for these trials will be provided by our MEASAT-3 satellite, which covers over 100 countries across the Asia Pacific. MEASAT looks forward to offering our MEASAT-3/3a platform at 91.5°E to provide both recorded and live 4k transmission, such as for the World Cup 2014 and 2016 Olympics,” concluded Raj.
