Next-gen Transmission Platform
The Electronics and Telecommunications Research Institute (ETRI) of Korea announced on Feb. 18 that it has co-developed ATSC 3.0, a next-generation transmission platform, with CleverLogic for the first time in the world, and successfully conducted its field test at VHF station in Cleveland, Ohio, along with the National Association of Broadcasters (NAB) of the U.S.
The field test was carried out in the U.S. for a month from Jan. with equipment developed by the ETRI at the request of the NAB.
The ETRI took part in the test by using ATSC 3.0 transmitter and receiver, which was developed by its research team for digital TV signal measurements, and high power devices.
The test was conducted in the Layered Division Multiplexing (LDM) mode, which can provide 4K UHD and mobile HD broadcasting at one broadcasting channel at the same time, fixed reception modes, which have same broadcasting service areas and transmission capacities with existing ATSC 1.0, and indoor reception mode, which works even under poor channel environments.
Lynn Claudy, vice chairman of the NAB, said, “This field test is the world’s first ATSC 3.0 technology verification with the use of VHF channel. It will greatly contribute to spectrum auction and broadcasting policy in North America in the future.”
Meanwhile, the ETRI submitted its LDM technology to the NAB Show 2015, the world’s largest broadcasting equipment trade show held in the U.S., in Apr. last year, and won “NAB technology innovation award.” Moreover, its technology was selected as ATSC 3.0 Candidate Standard established by Advanced Television Systems Committee, an international organization establishing broadcasting standards for digital, in Sept. last year.
Once the ETRI’s ATSC 3.0 system, including LDM technology, is approved as an international standard, the ETRI will be able to create royalties through securing a core standard patent and hold a dominant position in the initial ATSC 3.0 broadcasting market.
