The Integrated Services Digital Broadcasting (ISDB) is a Japanese standard for digital television (DTV) and digital radio used by the country's radio and television networks.


The core standards of ISDB are ISDB-S(satellite television), ISDB-T(terrestrial), ISDB-C (cable) and 2.6 GHz band mobile broadcasting which are all based on MPEG-2 or MPEG-4 standard for multiplexing with transport stream structure and video and audio coding (MPEG-2 or H.264), and are capable of high definition television (HDTV) and standard definition television. ISDB-T and ISDB-Tsb are for mobile reception in TV bands. 1seg is the name of an ISDB-T service for reception on cell phones, laptop computers and vehicles.


The concept was named for its similarity to ISDN, because both allow multiple channels of data to be transmitted together (a process called multiplexing).  ISDB-T operates on unused TV channels, an approach taken by other countries for TV but never before for radio.


ISDB replaced NTSC-J analog television system and the previously used MUSE Hi-vision analogue HDTV system in Japan, and will be replacing NTSC, PAL-M and PAL-N in South America. ISDB-T/TB solution is a perfect solution for supporting ISDB. Since many countries have adopted ISDB over other digital broadcasting standards, ISDB-T/TB will be increasing more acceptable in many areas in the futrure.
