Apparatus for digital video broadcasting

PURPOSE: A gateway apparatus for digital video broadcasting and an integrated digital broadcast signal sender are provided for conversion and transmission of broadcast signals including a digital terrestrial TV signal, a digital satellite TV signal, and a digital cable TV signal through a single broadcast signal sender. CONSTITUTION: A first module (110) receives content for digital broadcasting having at least one format among a transport stream (TS), generic streams (GSE), GFPS, and GCS, and converts the received content into physical layer pipes (PLP) for an input type. A second module (120) performs mode adaptation and stream adpataion with the PLPs according to a predetermined frame configuration method and converts the PLPs into a baseband frame for S2 or a baseband frame for C2. A third module (130) converts the baseband frame into an integrated X2MI packet of a predefined structure.
