Activity of Disseminating Japanese EWBS Technology

The Japanese digital terrestrial broadcasting system (ISDB-T) is adopted by 14 countries in Latin America. Japan provides technical cooperation to help the implementation of ISDB-T in those countries. EWBS (Emergency Warning Broadcasting System) is one of the particular features of ISDB-T and expected to be introduced as a national communication system in case of emergency. The ?EWBS Superimpose dissemination system? which is improved from the Japanese original by adapting to local requirements in Latin America has successfully developed in Japan. Taking advantage of the robustness of the ISDB-T ?One-seg? technology, making maximum use of the existing broadcasting network, this system realizes simple utilization and wide coverage with outstanding reliability. This system is already introduced to some Latin American countries and highly evaluated. Japan continues the technical cooperation so that EWBS can be contributed to disaster prevention and mitigation around the world.
