Abstract:
A method for transmitting a broadcast signal is discussed. The method includes generating transport packets of a transport stream having service data for a broadcast service, compressing headers of the transport packets and extracting context information from the transport packets according to a processing mode, encapsulating the transport packets into link layer packets for data, generating signaling information including the context information and information indicating the processing mode, encapsulating the signaling information into link layer packets for signaling, and transmitting the broadcast signal including the link layer packets for data and the link layer packets for signaling.

Claim (Index 3):
An apparatus for transmitting a broadcast signal, the apparatus comprising:\n an Internet Packet (IP) layer processor configured to generate transport packets of a transport stream having service data for a broadcast service; a link layer processor configured to compress headers of the transport packets and extract context information from the transport packets according to a processing mode, wherein the transport packets whose headers are compressed include IR packets, IR-DYN packets and compressed packets, wherein the link layer processor is further configured to encapsulate the transport packets into link layer packets for data, wherein a link layer packet for data includes a base header part, an additional header part and an extension header part, wherein the base header part includes information for indicating a type of the transport packets, wherein the additional header part includes indication information for indicating whether a first sub stream identifier is present in the link layer packet for data, wherein the extension header part includes the first sub stream identifier when the indication information indicates that the first sub stream identifier is present in the link layer packet for data, wherein the link layer processor is further configured to generate signaling information including the context information and information indicating the processing mode, wherein the signaling information further includes a second sub stream identifier having a same value as the first sub stream identifier, wherein the link layer processor is further configured to encapsulate the signaling information into link layer packets for signaling; and a transmitter configured to transmit the broadcast signal including the link layer packets for data and the link layer packets for signaling, wherein when the processing mode is a first mode, to extract the context information from the transport packets, the second module is further configured to: extract static context information from the IR packets and convert the IR packets to IR-DYN packets, and wherein when the processing mode is a second mode, to extract the context information from the transport packets, the second module is further configured to: extract static context information and dynamic context information from the IR packets and convert the IR packets to compressed packets, and extract dynamic context information from the IR-DYN packets and convert the IR-DYN packets to compressed packets.
