A Study on the Transmission System of an Advanced ISDB-T

Japan Broadcasting Corporation (NHK) has been conducting research and development on large-capacity transmission technologies for next-generation digital terrestrial television broadcasting (DTTB) system. In this work, a transmission system inherited Integrated Services Digital Broadcasting-Terrestrial (ISDB-T) has been developed, which can provide both fixed reception service and mobile reception service. The transmission system was developed with the aim of providing 4K/8K UHDTV broadcasting for fixed reception and HDTV broadcasting for mobile reception in one channel (6 MHz bandwidth). This report describes an overview of the transmission system for a next-generation DTTB called the advanced ISDB-T and its basic transmission performance.
