Abstract: An apparatus and a method for informing a disaster in a T-DMB(Terrestrial-Digital Multimedia Broadcasting) receiver are provided to detect a disaster region code value by analyzing a TII signal within a disaster broadcasting stream in a standby mode state and release the standby mode through comparison between the detected disaster region code values, thereby informing a user of generation of the disaster. A TII(Transmitter Identification Information) timing detecting module(106) detects timing information of a TII signal in a disaster broadcasting stream transmitted from a transmitter during a standby mode of a receiver. A carrier power detecting module(108) detects carrier power by using an FFT(Fast Fourier Transformed) TII signal according to the TII timing information. A TII decoder(110) decodes the FFT TII signal if the detected carrier power is higher than a predetermined reference value. A location calculating module(104) calculates a location code value of the receiver. A disaster notification signal generating module(112) generates a disaster notification signal if a disaster region code value is consistent with the location code value, calculated by the location calculating module, in the decoded TII signal. A control module(114) generates a control signal for notifying generation of a disaster according to the disaster notification signal.

Abstract: An advertisement method linking a rich media service and DMB is provided to enable a Rich Media server to provide additional advertisement information or the purchase process of a corresponding product in a predetermined Rich Media content type to a broadcasting receiver through a relay server and an advertisement server. A broadcasting system(110) provides a DMB(Digital Multimedia Broadcasting) signal to a broadcasting receiver(130). The broadcasting receiver displays the received DMB signal on a screen and determines whether a selection command for selecting an advertisement image is inputted from a user. The DMB player of the broadcasting receiver drives a Rich Media player. A Rich Media player requests a Rich Media server(140) to provide additional advertisement information. The Rich Media server searches a corresponding server and transmits a media data request to a relay server(150). The relay server relays the request of the Rich Media server to an advertisement server. The advertisement server transmits the requested media data to the relay server. The relay server relays the received media data to the Rich Media server and stores an accurate account result received from the advertisement server. The Rich Media server generates Rich Media contents for the additional advertisement information by using the received media data, transmits the Rich Media contents to the broadcasting receiver, transmits and stores the generated Rich Media contents to the relay server. The Rich Media player reproduces and displays the received Rich Media contents and provides an additional Rich Media service.

Abstract: A recording apparatus in a digital multi-media broadcasting receiver and a method thereof are provided to achieve recording suitable for a mobile circumference by storing only a normal stream. A recording apparatus in a digital multi-media broadcasting receiver includes a buffer(31), a buffer controller(32), a reference signal detector(33), and a PVR controller(34). The buffer temporarily stores digital data. The buffer controller buffers respective transport packets of a transport stream received by a digital multi-media broadcasting receiver. The reference signal detector detects a set reference signal from the transport packet. When the reference signal is detected, the PVR controller transfers and stores the stored transport packet to a storage medium. The reference signal includes a PCR(Program Clock Reference). The buffer controller starts buffering when a predetermined number of normal transport packets are detected from the transport packet.

Abstract: A method for assigning resources in bidirectional DMB(Digital Multimedia Broadcasting) is provided to connect to a mobile communication system quickly and assign the resources to a telematics terminal efficiently in the bidirectional DMB using the telematics terminal. A telematics terminal transmits a connection request signal to a mobile communication system while DMB is received(S301). If the connection request signal is received from the telematics terminal(S303), the mobile communication system confirms whether a specific terminal identification message exists in the received signal(S305). If the specific terminal identification message exists, the mobile communication system confirms whether available resources exist(S307). If the available resources exist, the mobile communication system calculates a priority value of the terminal according to the first type. If the specific terminal identification message does not exist, the mobile communication system confirms whether preliminary resources exist(S311). If the preliminary resources exist, the mobile communication system calculates a priority value of the terminal according to the second type. The mobile communication system assigns a transmission channel according to the calculated priority value(S317).
