A necessary packet is extracted from each of a plurality of transport streams, and the extracted packets are reconstructed to one transport stream. Plural packets from the reconstructed one transport stream are descrambled using a conditional access module, and the necessary packets are separated. Each packet separated from the reconstructed one transport stream is decoded. The conditional access module has information needed to descramble the packets from the plurality of transport streams that are in the reconstructed one transport stream. |
