Abstract: Provided is a system and method for transmitting and receiving 3D video based on digital broadcasting. The system includes: an encoder for generating 2D ES and 3D supplementary ES by encoding 2D video and 3D supplementary data; a packetizer for generating 2D video PES and 3D supplementary PES by packetizing the 2D video ES and the 3D supplementary ES; a PSI generator for generating a PSI; a TS generator for generating 2D video TS and 3D supplementary TS for the 2D video PES and the 3D supplementary PES; a multiplexer for multiplexing the transport streams to transmit the 2D video TS as a normal stream and transmit the 3D supplementary TS, the PSI TS and 3D video synch data TS as robust stream; and a modulator for modulating the multiplexed TS according to a DTV specification and transmitting the modulated TS.

Abstract: Disclosed herein is a method of operating an apparatus for providing a cell broadcast service. The operating method includes receiving, by a transmission device of a broadcaster, a cell broadcast service signal containing an emergency alert from a mobile carrier; converting, by the transmission device, the cell broadcast service signal into a public warning broadcast signal; and transmitting, by the transmission device, the public warning broadcast signal to a mobile switching center or a base station.

Abstract: Disclosed herein are an apparatus and method for converting a broadcast signal. The apparatus for converting a broadcast signal includes a demultiplexer unit for receiving a terrestrial broadcast signal and generating a terrestrial signaling signal, a signaling conversion unit for converting the terrestrial signaling signal into a cable signaling signal by parsing the terrestrial signaling signal, a cable multiplexer unit for generating a cable broadcast signal by multiplexing the cable signaling signal, and a cable modulation unit for modulating the cable broadcast signal and transmitting the cable broadcast signal over a cable network.
