Abstract:
1. A method of processing data for a broadcast receiver, the method comprising: receiving and demodulating a broadcast signal comprising groups that include first channel information including information for rapid mobile service acquisition, second channel information including version information for identifying an update of the first channel information, a plurality of known data sequences, and mobile service data in Reed-Solomon (RS) frames, wherein each of the RS frames is divided into a plurality of portions, and wherein each of the groups includes one of the plurality of portions, the plurality of known data sequences, a portion of the first channel information, and the second channel information; building the RS frames which belong to an ensemble by collecting the mobile service data of the demodulated broadcast signal; decoding the built RS frames for forward error correction (FEC); extracting a service map table (SMT) from the ensemble identified by an ensemble identifier, wherein Internet protocol (IP) datagrams carrying the SMT have a well-known target IP address and a well-known target user datagram protocol (UDP) port number; and accessing to IP datagrams of the mobile service data according to mobile service acquisition information included in the extracted SMT.
