Abstract

This chapter presents the Integrated Services Digital Broadcasting (ISDB) digital television (DTV) broadcast standard that is used in Japan. The three other primary DTV standards are Advanced Television Systems Committee (ATSC), Digital Video Broadcast (DVB), and OpenCable™. ISDB uses an MPEG-2 transport stream to convey compressed digital video, compressed digital audio, and data. Like DVB, this transport stream is then transmitted either via terrestrial, cable, or satellite. Interactive applications are based on BML (Broadcast Mark-up Language). Two satellite standards exist, ISDB-S, also known as the broadcast satellite (BS) system, and DVB-S, also known as the communications satellite (CS) system. The basic audio and video capabilities of ISDB are very similar. The major differences between them are the RF modulation schemes and the level of definition for non-audio/video services.
