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 6):
An apparatus for receiving a broadcast signal, the apparatus comprising:\n a tuner configured to receive the broadcast signal including link layer packets for data and link layer packets for signaling; a link layer processor configured to obtain link layer packets for signaling from the broadcast signal; and the link layer processor is further configured to obtain signaling information by decapsulating the link layer packets for signaling, wherein the signaling information includes context information and information indicating a processing mode, wherein the signaling information further includes a second sub stream identifier, wherein the link layer processor is further configured to obtain link layer packets for data from the broadcast signal, wherein a link layer packet for data includes a base header part, an additional header part and an extension header part, the base header part includes information for indicating a type of the transport packets, the additional header part includes indication information for indicating whether a first sub stream identifier is present in the link layer packet for data, and 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 filter at least one link layer packets each of which includes the first sub stream identifier having a same value as the second sub stream identifier from the obtained link layer packet for data, wherein the link layer processor is further configured to obtain transport packets whose headers are compressed and from which the context information is extracted according to the processing mode by decapsulating the filtered at least one link layer packets, wherein the link layer processor is further configured to combine the transport packets whose headers are compressed and from which the context information is extracted according to the processing mode and the context information of the signaling information, and decompress the transport packets whose headers are compressed, wherein when the processing mode is a first mode, to combine the transport packets whose headers are compressed and from which the context information is extracted according to the processing mode and the context information of the signaling information, the third module is further configured to combine IR-dynamic (IR-DYN) packets and static context information, and convert the IR-DYN packets to initialization and refresh (IR) packets, and wherein when the processing mode is a second mode, to combine the transport packets whose headers are compressed and from which the context information is extracted according to the processing mode and the context information of the signaling information, the third module is further configured to combine compressed packets, dynamic context information and static context information, and convert the compressed packets to IR packets.
