Digital broadcasting system and method for transmitting and receiving digital broadcast signal

Abstract

The disclosed method for processing a digital broadcast signal comprises encoding signaling information for mobile service data of the mobile service, the signaling information including first signaling data which includes transmission parameters and second signaling data which contains cross layer information between a physical layer and a upper layer, formatting a data group including known data, the first signal data and the mobile service data and transmitting the digital broadcast signal including data in the data group, wherein the mobile service in the digital broadcast signal is transmitted via first transmission mode or second transmission mode, wherein the slot is a basic time period for multiplexing of the mobile service data and main service data according to the first or second transmission mode, wherein the first signaling data includes slot indicating information identifying whether the slot is a slot for the first transmission mode or a slot for the second transmission mode.

What is claimed is: 
     
         1 . A method for transmitting broadcast signals, the method comprising:
 encoding mobile data for mobile service with a specific code rate;   interleaving the mobile data;   encoding signaling information including the specific code rate;   generating at least one data unit including the interleaved mobile data and the encoded signaling information; and   transmitting the broadcast signals including the at least one data unit,   wherein the at least one data unit is multiplexed with main data for main service by a time multiplexing scheme of the broadcast signals, and   wherein the at least one data unit further includes Fast Information Channel (FIC) data for a fast service acquisition.   
     
     
         2 . The method of  claim 1 , wherein the signaling information is the same within a group of data units for equal mobile service. 
     
     
         3 . The method of  claim 1 , wherein the signaling information further includes FIC version information for indicating a version of the FIC data. 
     
     
         4 . The method of  claim 1 , further comprising:
 inserting pilots into the broadcast signals.   
     
     
         5 . An apparatus for transmitting broadcast signals, the apparatus comprising:
 a first encoder for encoding mobile data for mobile service with a specific code rate;   an interleaver for interleaving the mobile data;   a second encoder for encoding signaling information including the specific code rate;   a formatter for generating at least one data unit including the interleaved mobile data and the encoded signaling information; and   a transmitter for transmitting the broadcast signals including the at least one data unit,   wherein the at least one data unit is multiplexed with main data for main service by a time multiplexing scheme of the broadcast signals, and   wherein the at least one data unit further includes Fast Information Channel (FIC) data for a fast service acquisition.   
     
     
         6 . The apparatus of  claim 5 , wherein the signaling information is the same within a group of data units for equal mobile service. 
     
     
         7 . The apparatus of  claim 5 , wherein the signaling information further includes FIC version information for indicating a version of the FIC data. 
     
     
         8 . The apparatus of  claim 5 , further comprising:
 an inserter for inserting pilots into the broadcast signals.
