Digital broadcasting system and data processing method
A method of processing broadcast data in a broadcast transmitting system includes Reed-Solomon (RS) encoding and Cyclic Redundancy Check encoding an RS frame payload including mobile service data to build an RS frame, wherein the RS frame payload comprises a plurality of mobile and handheld transport packets; first encoding data of the RS frame with a first encoding code; second encoding signaling data with a second encoding code, wherein the signaling data include fast information channel (FIC) data and transmission parameter channel (TPC) data, the FIC data including information for rapid mobile service acquisition and the TPC data including a parade identifier for identifying a parade to which a current data group belongs; mapping the first encoded data into data groups and adding known data sequences and the second encoded signaling data to each of the data groups; and transmitting a transmission frame including data of the data groups.
1. A method of processing broadcast data in a broadcast transmitting system, the method comprising:
encoding broadcast service data for a broadcast service, the broadcast service data being included in at least one data unit, wherein the at least one data unit includes an M-byte header, k bytes of stuffing data and an (N−M−k)-byte payload, wherein the header includes stuffing indication information indicating whether the stuffing data are included in the at least one data unit, wherein N and M are integers, and k is equal to or greater than 0, and wherein, when a length of the stuffing data is equal to or more than 3-byte, the length of the stuffing data is indicated by using a length indication field in the at least one data unit;
interleaving the encoded broadcast service data;
encoding signaling data for signaling the broadcast service data; and
modulating the interleaved broadcast service data and the encoded signaling data.
2. The method of claim 1 , wherein the modulated data are transmitted via a path.
3. The method of claim 2 , wherein the signaling data include identification information for identifying the path.
4. The method of claim 1 , wherein the signaling data include information for rapid acquisition of the broadcast service.
5. The method of claim 1 , wherein, when the length of the stuffing data is equal to or less than 2-byte, the length of the stuffing data is identified based on at least the stuffing indication field or the stuffing data.
6. A broadcast transmitting system for processing broadcast data, the broadcast transmitting system comprising:
an encoder for encoding broadcast service data for a broadcast service, the broadcast service data being included in at least one data unit, wherein the at least one data unit includes an M-byte header, k bytes of stuffing data and an (N−M−k)-byte payload, wherein the header includes stuffing indication information indicating whether the stuffing data are included in the at least one data unit, wherein N and M are integers, and k is equal to or greater than 0, and wherein, when a length of the stuffing data is equal to or more than 3-byte, the length of the stuffing data is indicated by using a length indication field in the least one data unit;
an interleaver for interleaving the encoded broadcast service data;
a signaling encoder for encoding signaling data for signaling the broadcast service data; and
a modulator for modulating the interleaved broadcast service data and the encoded signaling data.
7. The broadcast transmitting system of claim 6 , wherein the modulated data are transmitted via a path.
