Abstract: Disclosed are a broadcast signal transmitting apparatus, a broadcast signal receiving apparatus, and a broadcast signal transceiving method in the broadcast signal transmitting and receiving apparatuses. The broadcast signal transmitting method comprises the steps of: compressing headers of data packets which are included in an Internet protocol (IP) stream identified by access information, wherein the compressed data packets include a first packet containing both static information and dynamic information in the header thereof, and a second packet containing dynamic information in the header thereof; splitting the static information from the header of the first packet and diverting the remaining part thereof into the second packet; outputting an IP stream, which includes the second packet, via a data physical layer pipe (PLP); outputting, via a common PLP, a common stream, which includes the static information of the header of the first packet split in the previous step, compression information and IP-PLP mapping information for linking the IP stream and the data PLP; generating a signal frame on the basis of the data from the data PLP and the data of the common PLP; and transmitting a broadcast signal which includes the signal frame.
