・A Summary of the Research Work on Implementation of An Emergency Warning Broadcasting System (EWBS) for NEPAL [ABU2007]
This case study outlines for an EWBS technology for Nepal, focusing on Systems, Network Link, EWBS code and disaster management. It is a great challenge to the nation to establish EWBS to prevent loss of lives and properties from such frequent natural disaster. The model for EWBS network and delivery system as well as code configuration are mentioned.
*NHK has a program to offer young researchers from ABU countries the chance to conduct research at our laboratory. This paper describes the results of a visiting researcher from Nepal for one year.
・Earthquake and Tsunami Information Services via Data Broadcasting [ABU2007]
In January 2007 NHK began offering earthquake and tsunami information via data broadcasts, using three delivery media— satellite digital broadcasts, terrestrial digital broadcasts, and terrestrial digital broadcasts for mobile receivers (One-Seg). These services enable the rapid notification of information such as earthquake occurrences and tsunami warnings, reminders to exercise caution, as well as reports of earthquake intensity at different localities, to be displayed at any time on a receiver.
・Broadcasting Earthquake Early Warning - Development of a system for automatically airing such alerts - [ABU2007]
NHK has developed a system for relaying the alerts issued by the Meteorological Agency of Japan and started relaying alerts nationwide via all twelve of NHK’s radio and television channels. The Meteorological Agency of Japan has commenced an Earthquake Early Warning system, which can alert people to an approaching earthquake upon detecting its initial small-scale vibrations (primary waves) and by getting an estimated fix on its epicentre and magnitude (scale). The system can predict such factors as the amount of time remaining until the arrival of the earthquake’s main and potentially destructive vibrations (secondary waves), and the intensity (degree of jolting).
・Study on remote activation of One-Seg handheld receivers with Emergency Warning Broadcasting System [ABU2006]
Broadcasting is an ideal means to alert and to inform a large proportion of the population. The Emergency Warning System (EWS) is a broadcasting system which remotely activates receivers that are ready to receive such emergency warning signals, and transmits information to viewers and listeners about such disasters as earthquakes and tsunami, etc. The EWS has been in operation in Japan since 1985 for analog AM, FM sound and TV broadcasting. At present, the EWS is also in operation for digital satellite and digital terrestrial broadcasting. However, even if EWS-ready fixed-type receivers are remotely activated, they serve no purpose if no one is present to pick up the receiver. Thus EWS-ready portable type receivers installed in cellular phone terminals offer a way to make the EWS much more effective.
