DMB Receiver Model for Emergency Alert Service

This paper presents the method of emergency warning system operation based on T -DMB and th e design of T-DMB AEAS(Automatic Emergency Alert Service) receiver model. The proposed receiver model compares the geographical location of emergency with the location of DMB transmitting station from TDMB broadcasting signal and classifies the receiver location into alert region, neighboring region and non-alert region and transmits the emergency alert message according to each region. The proposed receiver model consists of the checking process of AEAS message from the received DMB signal, the verifying process of DMB transmitting location and the displaying process of AEAS m essage according to the classified region. In our experiment, we implemented the proposed rec eiver model with display section, storage section, DMB module for receiving broadcasting signal and control section and performed test emergency alert broadcasting using T-DMB signal generator.
