A study team of ETRI reveal the 8K-UHD media company technology which fulfills the North American broadcasting requirements to the full planet. By introducing domestic engineering in the fields of up coming-technology ultra-significant-resolution Television set broadcasting and conversation, the workforce is anticipated to direct the international 8K-UHD market place.

The Electronics and telecommunications analysis institute (ETRI) declared that it would participate in the “National Affiliation of Broadcasters (NAB) 2022” of the world’s greatest sizing, which will be held at the Las Vegas Convention Centre in the US for 4 times from the 24th, and introduce the most up-to-date 8K-UHD broadcasting and 5G convergence media broadcasting systems.

The 8K-UHD is a screen composed of far more than 33 million pixels. Simply because its resolution is 4 occasions bigger than 4K and, in depth expression in online video is feasible, it is deemed the top ultra-superior-resolution technological know-how. Additionally, as the changeover to the 8K media era is getting more rapidly, the necessity of developing broadcasting and media technologies to supply seamless 8K-UHD provider is also expanding.

The technologies by ETRI have uncovered in this exhibition, alongside with Korean broadcasting gear firms, are dependent on ATSC1) 3..

These are essential systems to give the 8K-UHD provider, such as MIMO2)-primarily based 8K service technological know-how which utilizes radio frequencies efficiently, OTA/OTT3) converged 8K company technological innovation which supplies actual-time streaming, and 5G-MBMS4) broadcasting procedure which provides terrestrial broadcasting provider to quite a few buyers.

MIMO is a technological innovation of doubling the transmission ability of present channels by implementing two antennas vertically and horizontally to the transmitter and receiver, respectively, without the need of incorporating a frequency useful resource.

As it is an progressive technological know-how to enable a large quantity transmission of 8K media by correctly employing the existing frequency without the need of becoming allocated with added frequency, the globe is shelling out attention to it. It is absolutely suitable with the ATSC 3. specifications, and it solved the difficulties of sign interference thanks to combining antennas.

Also, the ETRI analysis group demonstrated an 8K-UHD genuine-time streaming company by means of MIMO transmitter/receiver which complies with ATSC 3. typical, the North American terrestrial broadcasting common.

The technology released by ETRI in this exhibition is a pure Korean technologies developed via long-expression joint exploration with broadcasting products corporations such as KBS, CleverLogic, Kai Media, AGOS, and LowaSIS.

Madeleine Noland, head of ATSC, pointed out, “I am positive that the ATSC 3.-centered 8K-UHD services technological innovation and 5G convergence media provider know-how launched by ETRI will drop light on the way for the foreseeable future broadcasting.”

Also, Seung-chan Bang, Director of Conversation and Media Investigate Centre of ETRI, stated, “We will make full use of this NAB 2022 as the likelihood of publicizing the excellence of Korea’s 8K-UHD broadcasting technological innovation and 5G convergence media provider technological innovation as properly as primary the Korean companies’ world wide enlargement.”

In the long term, the ETRI investigation staff strategies to protected the technological foundation to observe ultra-superior-definition 8K broadcasting by maximizing the supply engineering. Also, the staff designs to go on added R&D for commercialization and standardization as the 8K current market expands.

ETRI’s broadcasting technology gained the “Technology Innovation Award” for the contribution to the advancement of a transmission technological know-how of mobile Hd and 4K-UHD solutions at the ‘NAB Exhibit 2015’ in 2015. On top of this award, this know-how has gained the ideal journal thesis award by IEEE Broadcast Technology Affiliation, a lot of greatest convention thesis awards, and so forth.


1) ATSC(State-of-the-art Television Devices Committee) : A standardization business which generates electronic broadcasting requirements in North The us

2) MIMO(Multi Input Multi Output) : Wireless transmission technologies which boosts facts transmission charge by applying two or additional transmit and get antennas

3) OTA(In excess of The Air)/OTT(About The Leading) : VOD this sort of as Netflix and Tving, and community Television set broadcasting which offers actual-time broadcasting services

4) MBMS(Multimedia Broadcast and Multicast Support) : terrestrial media company technology of the 3GPP communication typical



The investigate was performed backed by the South Korea Ministry of Science and ICT, these as 『Technology enhancement for transmitting ultra-high good quality UHD (UHQ)』, 『development for convergence transmission of 5G and broadcasting network (ATSC 3.) and base technology』 and 『technology enhancement for transmitting scalable assistance for 8K-class broadcasting』.
