Abstract: A broadcast signal transmission method comprises outputting an RoHC channel that includes one or more RoHC streams and a signaling table that includes information related to header compression by performing header compression for Internet Protocol (IP) packets, which include broadcast data, in accordance with an adaptation mode, a header of each IP packet including an IP header and a User Datagram Protocol (UDP) header, generating at least one first link layer packet that includes the RoHC channel and generating at least one second link layer packet that includes the signaling table, and physical layer processing the at least one first link layer packet and the at least one second link layer packet and transmitting through one or more Physical Layer Pipes (PLPs), wherein the signaling table includes adaptation mode information indicating the adaptation mode, and each RoHC stream in the RoHC channel includes RoHC packets.

Abstract: The present invention proposes a method of transmitting a broadcast signal. The method of transmitting a broadcast signal according to the present invention provides a system capable of supporting next-generation broadcast services in an environment supporting next-generation hybrid broadcast using terrestrial broadcast networks and the Internet. In addition, an efficient signaling method for covering terrestrial broadcast networks and the Internet in an environment supporting next-generation hybrid broadcast is proposed.
