Abstract: A transmitting and receiving apparatus and method for separating multiple broadcast signals from each other in a terrestrial cloud broadcast system are provided. A terrestrial cloud broadcast signal transmitting apparatus may include a plurality of transmitters for transmitting a plurality of terrestrial cloud broadcast signals, wherein each of the plurality of transmitters includes, an encoder encoding input data to generate a code word and a scrambler scrambling the generated code word using a scramble sequence uniquely allocated for each transmitter so that the plurality of terrestrial cloud broadcast signals are distinguished from each other.

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.
