A technology proposed by Samsung Electronics was selected as an interim standard for the next-generation ATSC 3.0 broadcast platform in the United States. The technology is also highly likely to be chosen as the next-generation terrestrial broadcast and UHD broadcast standards in South Korea.

Samsung Electronics announced on Sept. 29 that its technology was approved as the interim standard for the new ATSC 3.0 terrestrial broadcast platform after the U.S. Advanced Television Systems Committee (ATSC) conducted electronic voting for all member companies earlier this month.

The technology is the ATSC 3.0 physical layer standard and includes Low Density Parity Check (LDPC) and Non-Uniform Constellation (NUC) features. LDPC is a technology that effectively restores data loss that occurs when transmitting images. By reducing the information that is needed for restoration, it efficiently transmits UHD images. NUC is a method that modulates the frequency according to the reception environment of high definition images. It is a necessary technology to improve the efficiency of image transmissions for the next-generation UHD TV broadcasting.

Samsung Electronics’ interim standard technology will be established as the final standard next year. Since ATSC 3.0 has a high transmission efficiency, it not only allows many broadcast channels with one wavelength but also supports UHD broadcasting. In May, the “System Discovery and Signaling” (bootstrap) technology, which was jointly suggested by Samsung Electronics and ONE Media, a subsidiary of Sinclair Broadcast Group, Inc., the largest television broadcaster in the U.S., was selected as the first interim standard for the ATSC 3.0 physical layer standard.
