<P>PROBLEM TO BE SOLVED: To solve the problem wherein a retransmission apparatus at the head end of conventional CATV facilities does not support repacking or terrestrial digital broadcasting. <P>SOLUTION: The retransmission apparatus can support repacking automatically, because a monitoring unit 106 sends out a control signal so that a frequency converting unit 103 tracks physical channels, even if repacking is carried out. <P>COPYRIGHT: (C)2004,JPO |
