<p>The display section 35 connected to a control section 31 displays, at the same time, both the contents described in the network information table of the digital broadcast data demodulated by a demodulator 42 and complying with the first network, and also the contents described in the network information table of the digital broadcast data replaced by an NIT-replacing circuit 48 and complying with the second network. An NIT-detecting circuit 44 detects an NITa from an MPEG2 transport packet, i.e., digital broadcast data in the satellite broadcasting system (first network). The control section 31 complying with a CATV system (second network) generates the data representing at least the transmission frequency of the NITa detected by the NIT-detecting circuit 44. The NIT-replacing circuit 48 replaces the NITa contained in the MPEG2 transport packet, i.e., digital broadcast data in the satellite broadcasting system, with the NITb, thereby generating an MPEG2 transport packet, which will be used as digital broadcast data in the CATV system. <IMAGE></p> |
