TRANSMITTING/RECEIVING SYSTEM AND METHOD OF PROCESSING BROADCAST SIGNAL IN TRANSMITTING/RECEIVING SYSTEM
First Claim
1. A receiving system, comprising:
- a tuner for receiving a broadcast signal including a data group, wherein the data group includes at least mobile service data, a plurality of known data sequences, fast information channel (FIC) data, and transmission parameter channel (TPC) data, wherein the FIC data includes information for acquiring rapid mobile services, and wherein the TPC data includes version information of the FIC data;
a channel equalizer for channel-equalizing the broadcast signal by using at least one of the plurality of known data sequences;
a storage unit for storing mobile service data included in the channel-equalized broadcast signal, and repeatedly outputting the stored mobile service data for a predetermined number of turbo decoding iterations;
an inner decoder for matching the mobile service data being outputted from the storage unit with mobile service data being outer-decoded and fed-back and inner-decoding the matched mobile service data;
a deinterleaver for deinterleaving the inner-decoded mobile service data in block units;
an outer decoder for outer-decoding the deinterleaved mobile service data; and
an interleaver for interleaving the outer-decoded mobile service data in block units and feeding-back the interleaved mobile service data to the inner decoder.

Abstract
A transmitting system, a receiving system, and a method of processing broadcast signals are disclosed. The receiving system includes a tuner, a channel equalizer, a storage unit, an inner decoder, a deinterleaver, an outer decoder, and an interleaver. The tuner receives a broadcast signal including a data group. The channel equalizer channel-equalizes the broadcast signal. The storage unit stores mobile service data included in the channel-equalized broadcast signal, and repeatedly outputs the stored mobile service data for a predetermined number of turbo decoding iterations. The inner decoder matches the mobile service data being outputted from the storage unit with mobile service data being outer-decoded and fed-back and inner-decodes the matched mobile service data. The deinterleaver deinterleaves the inner-decoded mobile service data in block units. The outer decoder outer-decodes the deinterleaved mobile service data. The interleaver interleaves the outer-decoded mobile service data in block units and feeding-back the interleaved mobile service data to the inner decoder.

11. A method of processing a broadcast signal in a receiving system, the method comprising:
-
receiving, by a tuner, a broadcast signal including a data group, wherein the data group includes at least mobile service data, a plurality of known data sequences, fast information channel (FIC) data, and transmission parameter channel (TPC) data, wherein the FIC data includes information for acquiring rapid mobile services, and wherein the TPC data includes version information of the FIC data; channel-equalizing, by a channel equalizer, the broadcast signal by using at least one of the plurality of known data sequences; storing mobile service data included in the channel-equalized broadcast signal in a buffer, and repeatedly outputting the stored mobile service data for a predetermined number of turbo decoding iterations; matching, by an inner decoder, the mobile service data being outputted from the buffer with mobile service data being outer-decoded and fed-back and inner-decoding the matched mobile service data; deinterleaving, by a deinterleaver, the inner-decoded mobile service data in block units; outer-decoding, an outer decoder, the deinterleaved mobile service data; and interleaving, by an interleaver, the outer-decoded mobile service data in block units and feeding-back the interleaved mobile service data to the inner decoder. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
