Patent ID: 8391404

Claim:
A method of processing a digital broadcast signal in a transmitter, the method comprising: encoding signaling information including a transmission parameter channel (TPC) including transmission parameters, and a fast information channel (FIC) including cross layer information for mobile service acquisition, wherein the encoding the signal information comprises: performing a first error correction encoding on the FIC; multiplexing the first error correction encoded FIC with the TPC; and randomizing the multiplexed FIC and TPC; and transmitting the broadcast signal including ensembles including the encoded signaling information, wherein the FIC is divided into a number of FIC segments, wherein each of the FIC segments includes a FIC segment header and a FIC segment payload, wherein the FIC segment header includes type information indicating a type of the FIC segment, wherein the FIC further includes a first ensemble identifier identifying a specific ensemble including a service map table (SMT), and wherein the SMT comprises: a header including a second ensemble identifier corresponding to the first ensemble identifier; a payload including service acquisition information of the specific ensemble; and Internet Protocol (IP) access information of a mobile service for acquiring an IP datagram of the mobile service from the specific ensemble.
