ETRI Succeeds with Broadcasting Technology Demonstration

ETRI has become the first in the world to develop an LDM(Layered Division Multiplexing)-based
next-generation terrestrial broadcasting system that can provide 4K UHD
and mobile HD broadcasting through single transmitter and single channel.
Jointly developed with Clever Logic, this new technology was openly demonstrated
in a presentation on the results of the ATSC 3.0 LDM field test.
This achievement helps not only cut broadcasting costs,
but also to efficiently utilize frequency resources, a part of public goods.

The LDM technology was submitted to the ATSC(Advanced Television System Committee),
an international standards organization in the broadcasting area,
and adopted as a baseline technology for ATSC 3.0 international standards last February based on its outstanding features.
In a presentation on the interim results of the ATSC 3.0 LDM field test, a number of participated institutions expressed high interest
and expectations, including Pearl and Sinclair, US broadcasting companies;
NHK in Japan; and NERC DTV, a Chinese research institution for digital broadcasting.

Prospective Entry to European Markets with Int’l Standards

Once ATSC 3.0 including the LDM technology is finally approved as
an international standard, several values are expected to be created.
First, the new standards will bring royalties for core standard patents.
Second, it becomes possible to assume the dominant position in the early ATSC 3.0 broadcasting markets.
Furthermore, the new technology is expected to play a pivotal role
in the next-generation broadcasting services including 4K UHD and mobile HD broadcasting.
"ETRI is planning to offer its core technologies for the forthcoming DVB(Digital Video Broadcasting) project
and further strengthen its technological influence in the global broadcasting markets,”
said Dr. Nam Ho Hur, Director of Broadcasting System Research Department.
The new technology was developed with support from the “Developing next-generation terrestrial broadcasting transmission technology,”
a sub-project of the project of developing original technology for broadcasting, communications,
and convergent media with the theme “Developing convergent realistic broadcasting services and transmission technology,”
sponsored by the MSIP(Ministry of Science, ICT and future Planning)
and the IITP(Institute for Information & communications Technology Promotion).
This new technology brought ETRI the Technology Innovation Award at the 「NAB Show 2015」
held in the United States last April, the world’s largest exhibition for broadcasting equipment.
