Abstract: Disclosed is a broadcast signal transmitting apparatus, a broadcast signal receiving apparatus, and a broadcast signal transceiving method in a broadcast signal transceiving apparatus. The broadcast signal transmitting method comprises the following steps: compressing the headers of data packets of an IP stream identified by IP address information, wherein the compressed data packets include a first packet, the header of which contains static field information, a second packet, the header of which contains dynamic field information, and a third packet, the header of which contains the compressed static field information and/or the compressed dynamic field information; signaling IP-PLP mapping information for mapping the IP stream and a component PLP for transmitting the IP stream, the IP stream compression information, and the header information of the first packet to L2 signaling information; and transmitting the header information of the second and third packets via the component PLP, and transmitting the L2 signaling information via a common PLP.
