Method and apparatus of processing digital broadcasting signal in transmitter and receiver

An apparatus for transmitting broadcast signals, the apparatus comprising:

• a first encoder for Forward Error Correction (FEC) encoding mobile data for a broadcast service;
• a second encoder for encoding the FEC encoded mobile data at a specific code rate;
• a signaling encoder for encoding signaling data including transmission parameters and FIC data including cross-layer information to enable fast service acquisition;
• a frame generator for generating data frames including main data, the encoded mobile data, and the encoded signaling data;
• and
• a transmission unit for transmitting the broadcast signals including the data frames,
• wherein the transmission parameters include version information specifying a version of the FIC data.
