We are currently developing the advanced broadcasting system for the next generation of digital terrestrial television broadcasting (DTTB). Its physical layer, Advanced Integrated Services Digital Broadcasting-Terrestrial (Advanced ISDB-T), is based on frequency division multiplexing, and large-scale field tests have been conducted at experimental transmitter stations. Its transport layer, MPEG Media Transport (MMT), is based on Internet protocol (IP) and already used in ultra-high definition television (UHDTV) satellite broadcasting, and it enables to provide integrated broadcast and broadband services such as multi-view videos, content replacement, and augmented reality (AR)/virtual reality (VR) in TV programs. In order to show the feasibility of the advanced broadcasting system, complete verifications of it were conducted in four metropolitan cities of Japan. These verifications confirmed that basic services such as UHD content for fixed reception and HD content for mobile reception can be provided simultaneously. Furthermore, MMT/IP-based integrated broadcast-broadband services were verified using data both broadcast and broadband.
