Abstract:
1. A method for transmitting a broadcast signal, the method comprising: building a Reed-Solomon (RS) frame corresponding to an ensemble of a service of mobile data, the RS frame being a 2-dimensional data frame through which the mobile data belonging to the ensemble are Reed Solomon-cyclic redundancy check (RS-CRC) encoded, wherein the ensemble is a collection of services providing same quality of service; dividing the RS frame into a plurality of portions; encoding signaling data, wherein the signaling data includes fast information channel (FIC) data and transmission parameter channel (TPC) data, wherein the FIC data includes cross layer information between a physical layer and an upper layer; mapping data in one portion of the plurality of portions to data groups, wherein at least one of the data groups includes the encoded signaling data and known data sequences, and wherein the encoded signaling data is located between a first known data sequence of the known data sequences and a second known data sequence of the known data sequences; formatting data packets having data in the data groups; and transmitting a transmission frame having a parade of the data groups, wherein the TPC data includes an identifier of the parade and version information of the FIC data.
