<P>PROBLEM TO BE SOLVED: To provide a digital broadcast transmission apparatus capable of preliminarily preventing interference between a physical channel used to transmit digital broadcast signals and a physical channel used by the other digital broadcast transmission apparatus. <P>SOLUTION: When it is detected by an interference detection unit 12 that a physical channel used by a transmitting unit 14 to transmit digital broadcast signals and a physical channel used by other digital broadcast transmission apparatus to transmit digital broadcast signals interfere with each other or that there may arise interference between those physical channels, the transmitting unit 14 is instructed by a transmission physical channel assigning unit 13 to change the physical channel used to transmit digital broadcast signals to the other physical channel. Thus, interference between the physical channel used by the transmitting unit 14 and the physical channel used by the other digital broadcast transmission apparatus can be preliminarily prevented or eliminated. <P>COPYRIGHT: (C)2010,JPO&INPIT |
