摘要:
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.

A television transmitting system includes an encoder, a data randomizing and expanding unit, 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 randomizing and expanding unit randomizes the error-detection-coded data and expands the randomized data. The group formatter forms a group of enhanced data having one or more data regions and inserts the expanded enhanced data into at least one of the regions. The deinterleaver deinterleaves the group of enhanced data, and the packet formatter generates enhanced data packets.

A digital television (DTV) transmitting system includes a first frame decoder, a second frame decoder, and a frame multiplexer. The first frame decoder forms first enhanced data frames, encodes each data frame for error correction, forms a first super frame by combining the encoded first frames, and interleaves the first super frame. The second frame decoder forms second enhanced data frames, encodes each data frame for error correction, forms a second super frame by combining the encoded second frames, and interleaves the second super frame. The frame multiplexer multiplexes the interleaved first and second enhanced data frames.

A receiving system and a method for receiving and processing a broadcast signal including mobile service data are disclosed. The receiving system includes a tuner, a demodulator, a block decoder and an RS frame decoder. The tuner receives a broadcast signal including first mobile service data and second mobile service data. The demodulator demodulates the broadcast signal. The block decoder performs turbo-decoding on the first and second mobile service data included in the demodulated broadcast signal. The RS frame decoder builds a primary RS frame by collecting the turbo-decoded first mobile service data and performs error correction decoding on the primary RS frame. The RS frame decoder also builds a secondary RS frame by collecting the second mobile service data and performs error correction decoding on the secondary RS frame.

A digital broadcast transmitting/receiving system and a method for processing data are disclosed. The method for processing data may enhance the receiving performance of the receiving system by performing additional coding and multiplexing processes on the traffic information data and transmitting the processed data. Thus, robustness is provided to the traffic information data, thereby enabling the data to respond strongly against the channel environment which is always under constant and vast change.
