A exploration workforce of ETRI expose the 8K-UHD media services technological know-how which satisfies the North American broadcasting criteria to the full environment. By introducing domestic know-how in the fields of upcoming-era ultra-large-resolution Television set broadcasting and conversation, the group is expected to guide the international 8K-UHD market place.

The Electronics and telecommunications investigate institute (ETRI) announced 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 Center in the US for four times from the 24th, and introduce the most recent 8K-UHD broadcasting and 5G convergence media broadcasting systems.

The 8K-UHD is a screen composed of more than 33 million pixels. For the reason that its resolution is 4 times increased than 4K and, thorough expression in video is feasible, it is regarded as the main extremely-large-resolution technological know-how. Also, as the changeover to the 8K media era is receiving quicker, the requirement of building broadcasting and media systems to present seamless 8K-UHD service is also rising.

The technologies by ETRI have discovered in this exhibition, together with Korean broadcasting machines providers, are centered on ATSC1) 3..

These are critical systems to provide the 8K-UHD provider, such as MIMO2)-centered 8K services engineering which makes use of radio frequencies proficiently, OTA/OTT3) converged 8K assistance know-how which supplies actual-time streaming, and 5G-MBMS4) broadcasting process which provides terrestrial broadcasting assistance to a lot of users.

MIMO is a technological innovation of doubling the transmission ability of present channels by making use of two antennas vertically and horizontally to the transmitter and receiver, respectively, with out adding a frequency useful resource.

As it is an progressive know-how to allow a substantial quantity transmission of 8K media by correctly utilizing the current frequency without becoming allocated with supplemental frequency, the globe is spending awareness to it. It is completely compatible with the ATSC 3. requirements, and it fixed the complications of sign interference owing to combining antennas.

Also, the ETRI investigation group shown an 8K-UHD genuine-time streaming assistance by way of MIMO transmitter/receiver which complies with ATSC 3. standard, the North American terrestrial broadcasting regular.

The know-how introduced by ETRI in this exhibition is a pure Korean technology created through extensive-term joint analysis with broadcasting gear firms such as KBS, CleverLogic, Kai Media, AGOS, and LowaSIS.

Madeleine Noland, head of ATSC, pointed out, “I am confident that the ATSC 3.-based 8K-UHD services technological innovation and 5G convergence media support technologies released by ETRI will get rid of light on the way for the upcoming broadcasting.”

Also, Seung-chan Bang, Director of Communication and Media Investigate Heart of ETRI, talked about, “We will make total use of this NAB 2022 as the possibility of publicizing the excellence of Korea’s 8K-UHD broadcasting technological innovation and 5G convergence media provider know-how as very well as major the Korean companies’ world wide growth.”

In the long run, the ETRI research staff options to secure the specialized basis to observe extremely-high-definition 8K broadcasting by improving the source technological know-how. Also, the workforce plans to carry on supplemental R&D for commercialization and standardization as the 8K marketplace expands.

ETRI’s broadcasting technological know-how gained the “Technology Innovation Award” for the contribution to the progress of a transmission technological innovation of cell High definition and 4K-UHD companies at the ‘NAB Demonstrate 2015’ in 2015. On leading of this award, this technological innovation has won the best journal thesis award by IEEE Broadcast Technologies Affiliation, many very best conference thesis awards, etcetera.


1) ATSC(Advanced Tv Systems Committee) : A standardization corporation which generates electronic broadcasting standards in North The united states

2) MIMO(Multi Input Multi Output) : Wireless transmission technologies which boosts facts transmission rate by making use of two or extra transmit and receive antennas

3) OTA(Around The Air)/OTT(Around The Top rated) : VOD these kinds of as Netflix and Tving, and community Television broadcasting which provides serious-time broadcasting company

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



The analysis was performed backed by the South Korea Ministry of Science and ICT, these as 『Technology advancement for transmitting ultra-superior excellent UHD (UHQ)』, 『development for convergence transmission of 5G and broadcasting network (ATSC 3.) and foundation technology』 and 『technology improvement for transmitting scalable assistance for 8K-class broadcasting』.
