Abstract: PURPOSE: A MIMO(Multiple Input Multiple Output) transmission method in a digital video broadcasting system and a device thereof are provided to make an average output power of a signal inputted to each antenna equal or similar to each other. CONSTITUTION: An r2n-1 and an r2n are generated by the combination of a transmission signal modulated by 16QAM(Quadrature Amplitude Modulation) and QPSK(Quadrature Phase Shift Keying) modulation through a precoding process. A value with a different component size of 16QAM and QPSK is included in the r2n-1 and the r2n. The r2n-1 and the r2n have a different PAPR (Peak-to-Average Power Ratio) value from each other. A precoded r2n-1 and r2n are alternatively inputted to an amplifier connected to each antenna for the signal inputted to an amplifier before amplification of the output signal from antenna 1 and antenna 2.

Abstract: PURPOSE: A method for transmission of conditional access message for a terrestrial DMB is provided to reduce transmission capacitance of conditional access message. CONSTITUTION: A resource collector collects resources of vacant FIB(Fast information Block) and an MSC(Main Service Channel) domain among not used resources which are not used in each sub channel.
