ETRI research team reveals 8K-UHD media service technology that meets North American broadcast standards worldwide. By introducing domestic technology in the fields of next-generation ultra-high resolution television broadcasting and communication, the team is expected to lead the global 8K-UHD market.

The Electronics and Telecommunications Research Institute (ETRI) has announced that it will participate in the world’s largest “National Association of Broadcasters (NAB) 2022” to be held at the Las Vegas Convention Center in the United States. for four days starting on the 24th, and showcasing the latest in 8K-UHD media streaming and 5G convergence technologies.

8K-UHD is a screen made up of more than 33 million pixels. Because its resolution is 4 times higher than 4K and detailed expression in video is possible, it is considered the leading ultra-high resolution technology. Additionally, as the transition to the 8K media era accelerates, the need to develop broadcast and media technologies to deliver seamless 8K-UHD service also increases.

The technologies revealed by ETRI in this exhibition, as well as Korean broadcast equipment companies, are based on ATSC1) 3.0.

These are essential technologies to deliver 8K-UHD service, such as MIMO2)based on 8K service technology that makes efficient use of radio frequencies, OTA/OTT3) 8K converged service technology that provides real-time streaming and 5G-MBMS4) broadcasting system that provides terrestrial broadcasting service to many users.

MIMO is a technology that doubles the transmission capacity of existing channels by applying two antennas vertically and horizontally to the transmitter and receiver, respectively, without adding frequency resource.

As it is an innovative technology enabling high-volume transmission of 8K media by effectively using the existing frequency without being allocated to additional frequency, the world pays attention to it. It is fully compatible with ATSC 3.0 standards and solved signal interference problems due to antenna combination.

Additionally, the ETRI research team demonstrated an 8K-UHD real-time broadcast service via a MIMO transceiver that complies with ATSC 3.0, the North American terrestrial broadcast standard.

The technology exhibited by ETRI in this exhibition is a purely Korean technology developed through long-term joint research with broadcast equipment companies such as KBS, CleverLogic, Kai Media, AGOS, and LowaSIS.

Madeleine Noland, Head of ATSC, said, “I’m sure the 8K-UHD service technology based on ATSC 3.0 and 5G convergence media service technology introduced by ETRI will light the way forward for future broadcasting.”

In addition, Seung-chan Bang, Director of ETRI’s Communication and Media Research Center, said, “We will take full advantage of this NAB 2022 as an opportunity to showcase the excellence of 8K broadcast technology. -UHD and 5G convergence multimedia service technology in Korea. as well as leading the global expansion of Korean companies.

In the future, the ETRI research team plans to secure the technical basis for watching 8K ultra-high definition broadcasting by improving the source technology. Additionally, the team plans to continue additional R&D for commercialization and standardization as the 8K market grows.

ETRI’s broadcast technology won the “Technology Innovation Award” for its contribution to the development of HD and 4K-UHD mobile service transmission technology at the “NAB Show 2015” in 2015. In addition to this award, this technology has won the best journal thesis award by the IEEE Broadcast Technology Association, numerous best conference thesis awards, etc.

1) ATSC (Advanced Television Systems Committee): A standards body that creates digital broadcast standards in North America

2) MIMO (Multi Input Multi Output): wireless transmission technology that improves the data transmission rate by applying two or more transmitting and receiving antennas

3) OTA (Over The Air)/OTT (Over The Top): VOD like Netflix and Tving, and public television broadcasting that provides real-time streaming service

4) MBMS (Multimedia Broadcast and Multicast Service): terrestrial multimedia service technology of the 3GPP communication standard


The research was carried out with the support of the South Korean Ministry of Science and ICT, such as 『Technology development for ultra-high quality UHD (UHQ) transmission』, 『development for convergent transmission of 5G and network (ATSC 3.0) and core technology』 and 『Technology development for scalable service transmission for 8K class broadcasting』.
