Large-capacity transmission system for 8K broadcasting
・16APSK*1 modulation scheme that can transmit more information than existing schemes
・LDPC code that can improve error-correcting capability
◯This research is being conducted as part of a government-sponsored project of the Ministry of Internal Affairs and Communications, titled“Research & development of efficient use of frequency resource for ultra-high definition satellite and terrestrial broadcasting system”.
◯This system has been adopted as a ministerial ordinance, as well as an announcement, and a standard*2 of the Association of Radio Industries and Business.
*1 16APSK (Amplitude and Phase Shift Keying): A modulation scheme that transmits four bits of information simultaneously by changing the amplitude and phase of the carrier in 16 different ways.
*2 Standard: ARIB STD-B44 "Transmission System for Advanced Wide Band Digital Satellite Broadcasting"
