Abstract
Disclosed is a method of transmitting, by a transmission device, broadcast signals in a frequency-shared terrestrial broadcast system. The method includes generating the broadcast signals including pilot signals arranged at a physical layer frame based on a group identification (ID) defined according to a broadcast service, and transmitting the generated broadcast signals to a reception device, wherein the positions of the pilot signals arranged at the physical layer frame are different by group IDs.
