Abstract:
The present invention relates to an apparatus and a method for providing emergency information and supplementary information. A terminal for providing emergency information and supplementary information includes an EWAS processor to receive an EWAS signal, to determine whether an EWC is included in the EWAS signal, and to decode the EWC for acquiring the emergency information and the supplementary information; a region based service unit to decode the emergency information and the supplementary information to acquire service information including at least one service item, and to express an item label, an item description, broadcasting link information, and communications link information on the service item; and a terminal base function unit accessing a Wi-Fi network or a mobile communications network to perform communications or accessing a T-DMB network to receive broadcasting according to selection of a user, and to control web browsing environment for acquiring additional information through Internet access provided from the mobile communications network or Wi-Fi network. An automatic recognition service and a region based service are used to the highest degree as an advantage of an automatic recognition emergency broadcasting service and a low data transmission rate may be compensated.
Abstract:
An apparatus and a method for providing a digital broadcast signal are provided. The apparatus for providing a digital broadcast signal comprises a disaster broadcast unit which detects a first disaster message signal from a terrestrial DMB signal, and generates a second disaster message signal including a disaster broadcast activation data for emergency alert service for a radio shadow area based on a first field value of the first disaster message signal; and a broadcast signal relay unit which controls transmission of the second disaster massage signal transmitted from the disaster broadcast unit.
Abstract:
The present invention relates to a broadcasting transmission apparatus. Disclosed in the present specification is the broadcasting transmission apparatus which comprises an ATSC signal generation unit to transmit an ATSC signal in accordance with ATSC transmission standards; a low-speed data signal generation unit which has the same frequency range as that of the ATSC signal, and transmits at least one narrow-band signal located in a null frequency domain of an NTSC removal filter; a coupling unit to couple the ATSC signal to the at least one narrow-band signal; and an RF transmission unit to transmit the signal, coupled by the coupling unit, as an RF signal.
