ABSTRACT
68The Integrated Services Digital Broadcasting–Terrestrial (ISDB-T) was developed in Japan by the Association of Radio Industries and Businesses (ARIB) in 1998. 1 The ISDB-T provides audio, video, and multimedia services and integrates various kinds of digital contents, each of which may include high-definition TV (HDTV), multiprogram standard-definition TV (SDTV), and low-definition TV for portable reception and data (graphics, text, etc.). In Japan the ISDB-T was launched in 2003 for HDTV and SDTV, and in 2006 for portable reception. Also, in 2006, the Brazilian government adopted the International System for Digital Television (ISDTV), which uses the same modulation as ISDB-T. For both standards, portable reception, also called 1seg, means that the receiver can demodulate 428.57 KHz of the center of the broadcasting channel. This chapter describes the transmission system and the one-segment reception.
