DIGITAL SATELLITE BROADCASTING SYSTEM AND METHOD CAPABLE OF RETURNING ANSWER SIGNAL

摘要

Disclosed are a digital satellite broadcasting system capable of returning a response signal and a digital satellite broadcasting transmission/reception method thereof. The digital satellite broadcasting system according to the present invention includes a transmitter for transmitting digital satellite broadcasting, a first satellite repeater that receives digital satellite broadcasting transmitted by the transmitter and retransmits to the ground, and a digital satellite broadcasting that is retransmitted by the first satellite repeater A digital satellite broadcasting system comprising a receiver for receiving: a second satellite repeater for receiving a response signal corresponding to digital satellite broadcasting from the receiver and transmitting the received response signal to the transmitter; and a return information insertion unit that inserts information on the second satellite repeater as return information into the transmitted digital satellite broadcast, wherein the receiver responds to generating a response signal for the digital satellite broadcast received through the first satellite repeater signal generator; and a response signal transmitter for transmitting the response signal generated by the response signal generator to the second satellite repeater based on the return information.
