To transmit EPG information efficiently in a small volume of transmission,
it is so disposed that SDTs corresponding to respective transponders are
referred in an NIT stating the overall configuration of the network and
necessary information for reception. In each SDT, a real channel for
transmitting video signals and a corresponding dummy channel are provided
in a pair, and the dummy channel is provided with a gEMT and a dEMT for
stating information on events. An ETT is provided correspondingly to the
real channel. In an ETT, a gEMT is caused to be referred to. In a dEMT,
outline documents of events are stated, and in a gEMT information other
than the outline documents of events is stated.
