Digital broadcasting system and method of processing data in digital broadcasting system
First Claim
1. 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 signaling 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 digital 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), andwherein 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.

Abstract
A method of processing a digital broadcast signal in a transmitter includes encoding signaling information including a transmission parameter channel, including transmission parameters and a fast information channel (FIC) including cross layer information for mobile service acquisition, and transmitting the broadcast signal including ensembles including the encoded signaling information. The FIC is divided into FIC segments, each FIC segment including a FIC segment header and a FIC segment payload. The FIC segment header includes type information indicating a type of the FIC segment, the FIC further including a first ensemble identifier identifying a specific ensemble including a service map table (SMT). The SMT includes a header including a second ensemble identifier corresponding to the first ensemble identifier, a payload including service acquisition information of the specific ensemble, and IP access information of a mobile service for acquiring an IP datagram of the mobile service from the specific ensemble.
