Abstract: A DTV transmitting system includes an encoder, a randomizer, a block processor, a group formatter, a deinterleaver, and a packet formatter. The encoder codes enhanced data for error correction, permutes the coded data, and further codes the permuted data for error detection. The randomizer randomizes the coded enhanced data, and the block processor codes the randomized data at an effective coding rate of 1/H. The group formatter forms a group of enhanced data having data regions, and inserts the coded enhanced data into at least one of the data regions. The deinterleaver deinterleaves the group of enhanced data, and the packet formatter formats the deinterleaved data into corresponding data bytes.

Abstract: A digital broadcasting system and a data processing method are disclosed. A time zone identifier is inserted into program table information of a broadcasting signal and the broadcasting signal is transmitted/received. The digital broadcasting system can calculate a local time of a region, in which the digital broadcasting system is located, using the time zone identifier. Accordingly, although the position of the digital broadcasting system is changed, it is possible to process the broadcasting signal related to the local time without an error.

Abstract: A receiving system and a data processing method are disclosed. The receiving system includes a receiving unit, a demodulator, a first handler, and a second handler. The receiving unit receives a broadcast signal including fast information channel (FIC) data, mobile service data, and a service signaling channel, the FIC data including a field indicating that a table signaling service guide bootstrap information to the service signaling channel is included therein, and the mobile service data and the service signaling channel are packetized into an RS frame belonging to a desired ensemble. The demodulator demodulates the received broadcast signal. The first handler acquires service guide bootstrap information from the table included in the service signaling channel.

Abstract: A digital television (DTV) receiving system includes a tuner, a demodulator, a known data detector, an equalizer, a transmission detector, and a block decoder. The tuner receives a DTV signal having a data frame in which main and mobile service data are multiplexed. The demodulator demodulates the DTV signal, and the known data detector detects known data included in the mobile service data. The equalizer equalizes the demodulated DTV signal using the detected known data, and the transmission parameter detector detects an error correction mode from the equalized DTV signal. Finally, the block decoder decodes the equalized DTV signal for error correction using the detected error correction mode.

Abstract: A method is described for transmitting broadcast signals. First encoding of first broadcast service data is performed. Second encoding of the first encoded first broadcast service data is performed. The broadcast signals having the second encoded first broadcast service data multiplexed with second broadcast service data are transmitted. Each of the second encoded first broadcast service data and the second broadcast service data is allocated in a different data unit. The second encoded first broadcast service data and the second broadcast service data are allocated in different data units, respectively. Different robustness are allocated to the first broadcast service data and the second broadcast service data.
