Disclosed herein are an apparatus and method for detecting a broadcast signal. The apparatus includes a bootstrap detection unit for detecting whether a bootstrap signal is included in a received broadcast signal based on a preset first bootstrap window and a machine-learning method, a bootstrap offset estimation unit for searching the broadcast signal for the start point of the bootstrap signal using a preset second bootstrap window, estimating a bootstrap offset based on the machine-learning method, and estimating bootstrap symbols from the bootstrap offset, and a demodulation unit for demodulating information included in the broadcast signal from the bootstrap symbols based on the machine-learning method.

Apparatus and method for detecting broadcast signal

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.

Method and apparatus for cell broadcasting service using broadcast network

Disclosed are a dynamic multi-mode service (MMS) transmission apparatus, a dynamic MMS reception apparatus, and a method for providing a dynamic MMS. The method includes generating, by the dynamic MMS transmission apparatus, signaling information including information about linkage between service channels based on broadcast schedule information about a broadcast service; transmitting, by the dynamic MMS transmission apparatus, the signaling information and the broadcast service to the dynamic MMS reception apparatus through at least one of a broadcast network and a broadband network; receiving, by the dynamic MMS reception apparatus, the signaling information and the broadcast service; interpreting, by the dynamic MMS reception apparatus, the information about the linkage between service channels, included in the signaling information, by decoding the signaling information; and providing, by the dynamic MMS reception apparatus, the broadcast service by performing dynamic channel switching based on the information about the linkage between service channels.

Apparatus for converting broadcast signal and method for using the same

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.

System and method for transmitting/receiving three dimensional video based on digital broadcasting

A PSI converter includes: a protocol data extractor, a protocol data converter, a protocol data inserter, and a system controller. The protocol data extractor is configured for demultiplexing a terrestrial broadcasting TS or a satellite broadcasting TS, and extracting audio/video data and PSIP/PSI data or audio/video data and SI/PSI data from the terrestrial broadcasting TS or the satellite broadcasting TS, respectively. The protocol data converter is configured for converting the PSIP/PSI data or the SI/PSI data into PSIP/PSI data of a corresponding digital cable television broadcasting standard. The protocol data inserter is configured for inserting the digital cable television broadcasting standard PSIP/PSI data into the audio/video data extracted by the protocol data extractor though TS multiplexing, and generating a digital cable broadcasting TS. The system controller is configured for checking the protocol data extractor, the protocol data converter, and the protocol data inserter, and controlling their operation.
