<P>PROBLEM TO BE SOLVED: To provide a reception device for digital data which is adaptive to an error correction code having a longer code length, can freely combine a modulation system and an encoding rate with each other, and receives a transmission signal of multiple frames with which MPEG-2 TS and other digital data streams can be efficiently transmitted. <P>SOLUTION: The reception device 2, used for a satellite data transmission system performing time-division multiplex transmission of a plurality of kinds of digital modulation systems when receiving data of each slot of multiple frames which are generated by a transmission device 1, comprises N slots each comprising control information data, external code parity, a staff bit, and internal code parity and to which synchronizing, pilot, and transmission control signals and parity are added and receives the transmission control signal first, and then receives signals other than the transmission control signal on the basis of the configuration of the multiple frames and the contents of the transmission control signal. <P>COPYRIGHT: (C)2009,JPO&INPIT |
