Technologies proposed by Samsung Electronics was selected as candidate standard for the U.S. next-generation terrestrial broadcast ATSC 3.0.
The technology, standard for physical layer of ATSC 3.0, includes Low Density Parity Check(LDPC) and Non Uniform Constellation(NUC).
LDPC is a technology effectively recovering data lost in the process of transferring data. It allows effective transmission of ultra-definition video by reducing code needed for recovery.
NUC is a technology to alter frequency by optimizing high-definition video into the reception condition. It is necessary to improve the efficiency of video transmission for next-generation high-definition broadcast.
Advanced Television Systems Committee took a vote on Samsung's technology from the beginning of this month, and officially approved Samsung’s technology as candidate standard.
As the U.S. next-generation terrestrial broadcast, ATSC 3.0 allows multiple channels with one frequency, and also supports UHD broadcast.
Also in May, Samsung Electronics' Bootstrap technology co-proposed by ONE Media of SBG was selected as the first candidate standard for physical layer of ATSC 3.0,
