JTEC as an entrusted organization by the Ministry of Internal Affairs and Communications of Japan as well as a member of DiBEG*, provides technical support for the spread of Japanese digital TV standard, ISDB-T to Latin American countries.

The Emergency Warning Broadcast System (EWBS) is one of the key features of ISDB-T and is expected to be introduced as a national communication system for emergency situations. The “EWBS Superimpose Dissemination System” by adapting to numerous local requirements in Latin America, has successfully been developed in Japan. Taking advantage of the robustness of the ISDB-T “One-seg” technology, making maximum use of the existing broadcasting networks, this system realizes simple utilization and wide coverage with outstanding reliability. This system has already been introduced to some Latin American countries and been evaluated highly. Japan continues technical cooperation so that EWBS can contribute to disaster prevention and mitigation in these ISDB-T adopting countries.
