Patent ID: 8165244

Claim:
A method of processing a digital broadcast signal in a transmitter, the method comprising: building Reed-Solomon (RS) frames through which mobile service data are RS and cyclic redundancy check (CRC) encoded; 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; and transmitting the broadcast signal including ensembles, wherein the ensembles include data groups including the mobile service data in the built RS frames and the encoded signaling information, wherein the encoded signaling information is inserted into a reserved area in each data group, wherein the FIC further includes a first ensemble identifier identifying a specific ensemble, wherein the specific ensemble includes a service map table (SMT), the SMT comprising a header and a payload, the header including a second ensemble identifier corresponding to the first ensemble identifier, the payload including service acquisition information of the specific ensemble, the SMT further comprising Internet Protocol (IP) access information of a mobile service for acquiring an IP datagram of the mobile service from the specific ensemble.
