TRANSMITTING/RECEIVING SYSTEM AND BROADCAST SIGNAL PROCESSING METHOD

摘要

Disclosed is a receiving system which receives and processes broadcast signals containing mobile service data and a broadcast signal processing method. Said receiving system comprises a tuner, a demodulator, a block decoder and an RS frame decoder. Said tuner receives broadcast signals containing first mobile service data and second mobile service data using slots. Said slots consist of M1 number of packets, and within the M1 number of packets of said slots are M2 number of packets including first mobile service data and a plurality of base data rows. At least one packet among M3 number of remaining packets (here M1=M2+M3, M2>M3) includes the second mobile service data. Said demodulator demodulates said broadcast signal. Said block decoder turbo-decodes first and second mobile service data contained in said demodulated broadcast signal. Said RS frame decoder forms a primary RS frame by collecting said turbo-decoded first mobile service data thereby performing error correction in the decoding operation and forms a second RS frame by collecting second mobile service data thereby performing an error correction in the decoding operation.
