A method and apparatus for transmitting and receiving a broadcast signal including a robust header compression (RoHC) packet stream are disclosed. The broadcast signal transmitting method includes compressing a header of an IP packet included in an IP packet stream to output an RoHC (Robust Header Compression) packet stream, generating a signaling packet including information of at least one RoHC packets included the RoHC packet stream, wherein the signaling packet includes a signaling packet header and a signaling packet payload, wherein the signaling packet header includes signaling information that is included in the signaling packet payload, transporting the signaling packet through a first channel and transporting the RoHC packet stream through a second channel.
