Demonstration of a media transmission service that allows viewing 3D images without glasses on a moving bus.

Following the provision of gigabit Wi-Fi in the Seoul subway, the company successfully demonstrated 5Gbps transmission on a moving bus.

The Electronics and Telecommunications Research Institute (ETRI) announced that this technology is the result of joint research between Korea and the European Union (EU) on 5th generation (G), and demonstrated it to the public at the Gangneung ICT Promotion Center from the 2nd.

ETRI announced on the 21st that it successfully demonstrated a multi-viewpoint media transmission service that allows users to view 3D images without glasses on a moving bus using 5 Gbps mobile hotspot network (MHN)-E technology on Yulgok-ro, Gangneung-si.

The MHN-E (Enhanced) technology utilized in this demonstration is an advanced version of MHN technology that successfully completed its final technology verification on Seoul Subway Line 8 at the end of last year to provide gigabit Wi-Fi service, and is being unveiled for the first time through this demonstration.

MHN-E transmits data more than four times faster than existing MHN technology. By introducing multiple-antenna (MIMO) technology that expands bandwidth and improves data transmission efficiency, data transmission of up to 5 gigabits per second (Gbps) is now possible, which is about four times faster than the existing 1.25 Gbps MHN technology.

Because data transmission is so fast, it is now possible to transmit 3D images, virtual reality (VR), and augmented reality (AR) content that can be viewed without glasses, such as multi-view media that was previously impossible to transmit using conventional communications.

A demonstration held on the 21st demonstrated how a bus, utilizing the MHN-E technology developed by the research team, could seamlessly transmit and receive video while driving through downtown Gangneung. The researchers explained that if this technology were applied to highways, approximately 2,500 bus passengers within 500 meters would be able to simultaneously view HD-quality video.

The research team successfully verified software-based 5G mobile core functions in a virtualized environment. Furthermore, they demonstrated interoperability of mobile core and management functions between Korea and Europe using international standards-based orchestration technology.

For this type of data transmission, ETRI applied ▲high-resolution multi-view media generation technology with more than 60 viewpoints ▲gigabit data transmission and error recovery technology linked to 5G networks using the MMT standard, MPEG's next-generation media transmission standard ▲multi-view media display technology using a 55-inch 60-view terminal.

ETRI 5G Giga Service Research Division Director Jeong Hyeon-gyu said, “We expect that the exhibition and demonstration of the Korea-EU 5G joint research results at the Gangneung Promotion Center will serve as an opportunity to promote Korea’s advanced ICT to the world and serve as a good opportunity for related companies to enter overseas markets.”
