Abstract:
1. A method of processing data for a receiver, the method comprising: receiving a broadcast signal comprising a frame including a plurality of sub-frames, each of the plurality of sub-frames including data groups, wherein the data groups include: wherein the mobile service data is RS-CRC (Reed-Solomon-cyclic redundancy check) encoded through a Reed-Solomon (RS) frame, the TPC data is RS-encoded at a first code rate, and the FIC data is block-interleaved after being RS-encoded at a second code rate, and wherein the TPC data is not included in the FIC data; decoding the RS frame received via the broadcast signal, wherein the RS frame is built using the mobile service data in the broadcast signal, a CRC syndrome checking process and an RS decoding process are performed on the built RS frame; acquiring an ensemble identified by an ensemble identifier from the decoded RS frame and acquiring a service map table (SMT) from the ensemble, the SMT including access information of each mobile service included in the ensemble and service type information identifying a category of each mobile service; and acquiring service guide data based on the service type information included in the SMT, wherein the ensemble is carried through a parade, the parade being a collection of the data groups and the TPC data further includes information for a parade repetition cycle which represents a number of frames which do not contain a current parade and which are between frames that contain the current parade, and wherein the TPC data is included in each of the data groups belonging to the parade and same information for the parade repetition cycle is received repeatedly through the data groups of the parade.
