<P>PROBLEM TO BE SOLVED: To transmit one transport stream by multiplexing a plurality of one-segment transport streams into the one transport stream. <P>SOLUTION: Receivers 1-1 to 1-13 receive respectively different one-segments TS, and NULL packet elimination filters 2-1 to 2-13 corresponding to the receivers 1-1 to 1-13 eliminate NULL packets from the one-segments TS. When switches 5-1 to 5-13, 8 and 11 sequentially acquire data or NULL packets from FIFOs 3-1 to 3-13 or NULL packet generating parts 4-1 to 4-13, or the like for generating NULL packets after the remaining data is stored in the FIFOs 3-1 to 3-13, a hierarchy information adding part 14 adds hierarchy information for identifying the respective data or NULL Packets to the data or NULL packets so as to make them to be one transport stream. <P>COPYRIGHT: (C)2009,JPO&INPIT |
