A research team of ETRI expose the 8K-UHD media services technological know-how which fulfills the North American broadcasting standards to the total earth. By introducing domestic technological innovation in the fields of subsequent-generation extremely-higher-resolution Television set broadcasting and conversation, the team is anticipated to guide the worldwide 8K-UHD market.

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

The 8K-UHD is a monitor composed of extra than 33 million pixels. Due to the fact its resolution is 4 occasions bigger than 4K and, in-depth expression in movie is doable, it is deemed the top ultra-superior-resolution technological know-how. Furthermore, as the changeover to the 8K media period is getting a lot quicker, the requirement of establishing broadcasting and media systems to give seamless 8K-UHD provider is also rising.

The systems by ETRI have revealed in this exhibition, along with Korean broadcasting products organizations, are dependent on ATSC1) 3..

These are necessary technologies to supply the 8K-UHD assistance, this sort of as MIMO2)-primarily based 8K company technological innovation which takes advantage of radio frequencies competently, OTA/OTT3) converged 8K support technological innovation which gives serious-time streaming, and 5G-MBMS4) broadcasting method which gives terrestrial broadcasting provider to quite a few people.

MIMO is a technological know-how of doubling the transmission capability of present channels by applying two antennas vertically and horizontally to the transmitter and receiver, respectively, without having introducing a frequency useful resource.

As it is an modern technological know-how to help a big quantity transmission of 8K media by properly using the current frequency with no staying allocated with supplemental frequency, the entire world is shelling out focus to it. It is totally compatible with the ATSC 3. requirements, and it solved the challenges of sign interference owing to combining antennas.

Also, the ETRI exploration crew shown an 8K-UHD genuine-time streaming support by MIMO transmitter/receiver which complies with ATSC 3. regular, the North American terrestrial broadcasting conventional.

The technological know-how introduced by ETRI in this exhibition is a pure Korean technologies created as a result of lengthy-time period joint research with broadcasting products organizations these types of as KBS, CleverLogic, Kai Media, AGOS, and LowaSIS.

Madeleine Noland, head of ATSC, mentioned, “I am confident that the ATSC 3.-based mostly 8K-UHD assistance engineering and 5G convergence media services technological know-how introduced by ETRI will get rid of light-weight on the way for the upcoming broadcasting.”

Also, Seung-chan Bang, Director of Conversation and Media Analysis Center of ETRI, pointed out, “We will make comprehensive use of this NAB 2022 as the prospect of publicizing the excellence of Korea’s 8K-UHD broadcasting technological know-how and 5G convergence media support engineering as properly as top the Korean companies’ world wide enlargement.”

In the future, the ETRI analysis workforce plans to secure the complex basis to enjoy extremely-significant-definition 8K broadcasting by boosting the source technologies. Also, the group programs to continue on further R&D for commercialization and standardization as the 8K market expands.

ETRI’s broadcasting technologies won the “Technology Innovation Award” for the contribution to the progress of a transmission technology of cellular High definition and 4K-UHD services at the ‘NAB Display 2015’ in 2015. On top rated of this award, this know-how has won the most effective journal thesis award by IEEE Broadcast Technological know-how Affiliation, quite a few ideal convention thesis awards, and so forth.


1) ATSC(State-of-the-art Tv Units Committee) : A standardization corporation which results in electronic broadcasting benchmarks in North America

2) MIMO(Multi Enter Multi Output) : Wi-fi transmission know-how which enhances knowledge transmission fee by making use of two or more transmit and get antennas

3) OTA(Above The Air)/OTT(About The Top rated) : VOD these types of as Netflix and Tving, and public Television broadcasting which presents real-time broadcasting provider

4) MBMS(Multimedia Broadcast and Multicast Support) : terrestrial media company know-how of the 3GPP conversation standard



The exploration was done backed by the South Korea Ministry of Science and ICT, these types of as 『Technology advancement for transmitting extremely-high high-quality UHD (UHQ)』, 『development for convergence transmission of 5G and broadcasting community (ATSC 3.) and base technology』 and 『technology progress for transmitting scalable company for 8K-course broadcasting』.
