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 broadcast receiving system capable of receiving mobile broadcast data and a method for processing broadcast signals are disclosed. The broadcast receiving system includes N number of antenna elements, a demodulator, a transmission parameter detector, and a block decoder. The N number of antenna elements receives each of the broadcast signals. The demodulator demodulates the broadcast signal having greater signal strength among each of the received broadcast signals. The transmission parameter detector detects the transmission parameter. The block decoder symbol-decodes the mobile broadcast service data included in the received broadcast signal in block units, based upon the detected transmission parameter.

Abstract: A broadcasting signal receiver and a method for transmitting/receiving a broadcasting signal are disclosed. An identifier of a cell is configured in second program table information or signaling information of the broadcasting signal. If the cell is changed, channel information of the changed cell can be obtained from second program table information in which transmission channel information of each cell for a broadcasting program is configured. Accordingly, the broadcasting signal receiver can continuously output the program although the cell is changed.

Abstract: A digital broadcasting system and a method of processing data are disclosed. Herein, additional encoding is performed on mobile service data, which are then transmitted, thereby providing robustness in the processed mobile service data, so that the mobile service data can respond more strongly against fast and frequent channel changes. In a transmitting system including a service multiplexer and a transmitter located in a remote site, a method of processing data of the transmitting system includes comparing an output data rate of the service multiplexer and a transmission data rate of the transmitter, when a difference occurs between the two data rates, adjusting a burst size, wherein the burst transmits mobile service data, and encoding the mobile service data, and referring to the burst size so as to multiplex main service data and the encoded mobile service data in a burst structure.

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.
