Digital broadcasting gateway apparatus and integrated digital broadcast signal transmitter

Disclosed herein is a digital broadcasting gateway apparatus and integrated digital broadcast signal transmitter, which can convert digital content into integrated X2MI packets and transmit the X2MI packets, thus providing broadcasting services for terrestrial, satellite, and cable broadcasting media. The digital broadcasting gateway apparatus includes a first module for receiving digital broadcast content configured in at least one of Transport Stream (TS), Generic Stream Encapsulation (GSE), Generic Fixed Packetized Stream (GFPS), Generic Continuous Stream (GCS) formats, and converting the digital broadcast content into Physical Layer Pipes (PLPs) conforming to an input scheme. A second module performs mode adaptation and stream adaptation on the PLPs depending on a preset frame configuration scheme and then converting the PLPs into baseband frames for S2 or C2. A third module converts the baseband frames into an integrated X2MI packet configured in predefined format.
