<p>PROBLEM TO BE SOLVED: To solve the problem that, although it is needed to switch broadcast signals received by a plurality of receiver stations and broadcast them in accordance with signal quality since satellite broadcasting is easily influenced by a rainfall condition or the like, in the configuration where a broadcast signal received from a satellite is made into IP packet and transmitted to a transmitter station via a transmission line of an IP network or the like, since timing to transmit the broadcast signal to the transmitter station via receiver stations A and B is made different by transmission line delay or the like, mismatching may occur in data in accordance with timing of switching and data may not become sequential.SOLUTION: The present invention relates to a technology for transmitting broadcast signals which are broadcasted by terrestrial digital broadcasting or satellite digital broadcasting over the IP network, or in more detail, relates to a broadcast signal IP transmission system and a broadcast signal IP transmission method capable of switching the broadcast signal made into IP packet in a seamless manner in accordance with a reception signal status depending on the rainfall condition or the like.</p> |
