LG confirms ATSC 3.0 Korea 4K TVs
January 11, 2018
LG Electronics, co-developer of the ATSC 3.0 next-generation television broadcast standard, has confirmed that all LG 4K Ultra HD TVs now on the market in South Korea already incorporate ATSC 3.0 tuning circuitry. At CES 2018 in Las Vegas, where the Advanced Television Systems Committee (ATSC) officially released the new suite of standards, LG announced plans to support broadcast trials and early deployment testing in the United States during 2018.
Korea adopted the Next Gen TV standard in 2017 and leading broadcasters KBS, MBC and SBS launched ATSC 3.0 broadcasting in advance of 4K UHD transmission of next month’s 2018 Winter Games in Pyeongchang. Since last autumn, all new LG 4K UHD TVs and most new LG smart TVs sold in Korea have included dual ATSC 3.0-ATSC 1.0 tuner chips.
To support initial US Next Gen TV broadcast deployments, LG said it will leverage its marketplace experience from the launch of Next Gen TV in Korea and its technical expertise as co-developer of ATSC 3.0, which has been hailed as the world’s first Internet Protocol-based TV broadcast system.
The US Federal Communications Commission approved key elements of the ATSC 3.0 broadcast standard in November 2017 for voluntary implementation of Next Gen TV. “The flexible, extensible new ATSC 3.0 standard will unleash an innovation revolution, marrying broadband and broadcasting to deliver a range of new services for consumers in Korea, the US and around the world,” said Dr. Jong G. Kim, Senior Vice President in the Office of the CTO, LG Electronics.
Technologies developed by LG, along with Zenith, its U.S. R&D subsidiary, are included in all three major layers of the ATSC 3.0 standard, explained Kim, who also serves as President of the Zenith R&D Lab. LG contributions are in the majority of the A/322 Physical Layer Standard adopted by the FCC, including the scrambler, forward error correction, bit interleaver, mapper, time interleaver, OFDM framer, frequency interleaver, pilots, reserved tones, and guard interval functions.
Expected to redefine TV broadcasting for decades to come, the ATSC 3.0 broadcast standard is designed to deliver 4K Ultra HD and immersive audio, robust reception on mobile devices and improved spectrum efficiency. The increased payload capacity of the physical layer combined with HEVC encoding will allow broadcasters more options for expanding their broadcast service offerings, including business-to-business opportunities in new markets such as the automotive segment.
Development of ATSC 3.0 technologies represents the latest digital television innovations by LG and Zenith, long-time supporters of US terrestrial broadcasting, including the A/153 Mobile Digital TV Standard adopted by the industry in 2009. Zenith developed the core transmission system at the heart of today’s ATSC 1.0 A/53 Digital Television Standard, approved by the FCC two decades ago.
