TRANSMITTING / RECEIVING SYSTEMS AND BROADCASTING SIGNAL PROCESSING METHOD

摘要

The present invention relates to a transmitting system, a receiving system, and a broadcasting signal processing method. The receiving system comprises a tuner, a demodulator, a block decoder, an RS frame decoder, and a service manager. The tuner includes mobile service data, a service map table (SMT) for signaling access information of the mobile service data, and multiple base data columns, and the mobile service data and SMT receive a broadcasting signal packetized in the RS frame. The demodulator demodulates the received broadcasting signal. The block decoder turbo-decodes the mobile service data and SMT, which are included in the demodulated broadcasting signal, by block units. The RS frame decoder forms an RS frame which includes turbo-decoded mobile service data and SMT, performs a 1st CRC decoding process and an RS decoding process for the RS frame, and performs a 2nd CRC decoding process for the RS frame which is decoded through the 1st CRC decoding process and the RS decoding process. The service manager obtains source IP address information of an IP datagram of the mobile service data decoded in the RS frame, from a service map table.
