Busan Signs LOI with U.S. Broadcasters to Expand Core Technology and Activate AI Media Services

내용

Busan Metropolitan City Mayor Park Heong-joon announced that the city introduced its cloud-based, next-generation AI 3D immersive media service technology at the 2025 NABSHOW, the world’s largest broadcasting equipment exhibition, held in Las Vegas, USA from April 5 to 9.

The featured AI immersive media technology, developed jointly by the Busan Research Center of the Electronics and Telecommunications Research Institute (ETRI) and Busan City, was unveiled on April 7 and received significant attention.

This next-generation AI immersive media service technology is capable of delivering ultra-high-definition (UHD), virtual reality (VR), and 3D content over both broadcasting and internet streaming platforms (OTT) while maintaining compatibility with 2D services.

Notably, this innovation allows for 3D viewing without requiring changes to the existing 2D transmission infrastructure, as the data transmission size remains the same.

Earlier this year, the Advanced Television Systems Committee (ATSC) officially adopted this technology as part of the ATSC 3.0 international standard, further validating its global relevance.

To accelerate the spread and commercialization of this core technology, Busan City and ETRI signed Letters of Intent (LOIs) for business cooperation with:

• ●CAST.ERA

• ●KAIMEDIA (Korea)

• ●SINCLAIR Broadcast Group (United States)

Kim Sung-hoon, Head of the ETRI Busan Research Center, stated:

“This LOI signifies global recognition for advanced media technologies supported by Busan.
Through collaborations with major U.S. broadcasters, we plan to accelerate the global deployment and commercialization of our AI immersive media services.”

Jeong Na-young, Director General of Busan’s Bureau of Future Technology Strategy, added:

“This achievement will contribute to upgrading Busan’s broadcasting infrastructure and support the city’s goal of becoming a leading hub for film and media content.
Moving forward, we will continue working with local broadcasters and related media organizations to expand the domestic and international adoption of next-generation AI immersive media services.”
