摘要:
A digital broadcasting system and method of processing data are disclosed. Herein, a method of processing data of a transmitting system includes generating a service informative null packet including service-related information of mobile service data, and multiplexing a plurality of main service data packets, a plurality of mobile service data packets, and a plurality of service informative null packets, and transmitting the multiplexed data packets to at least one transmitter located in a remote site. The digital broadcasting system and method of processing data may enhance receiving performance of a receiving system by performing additional encoding on mobile service data and by transmitting the processed data to the receiving system.

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.

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.

A digital television (DTV) transmitting system is provided that includes an encoder, a group formatter, a packet formatter and a transmission unit. The group formatter forms data groups where the plurality of second known data sequences are spaced 16 segments apart within at least one of the data groups that includes a transmission parameter inserted between the first known data sequence and the plurality of second known data sequences and the first known data sequence has a first M-symbol sequence and a second M-symbol sequence, the first M-symbol sequence and the second M-symbol sequence have a first pattern, each of the plurality of second known data sequences has a second pattern other than the first pattern, and the second pattern is positioned from a last symbol to a previous N symbol in each of the plurality of second known data sequences.

A broadcast transmitting system includes a first randomizer randomizing mobile service data bytes; a Reed-Solomon (RS) frame encoder generating an RS frame and dividing the RS frame into RS frame portions; a first interleaver interleaving symbols corresponding to data in the RS frame portions; a group formatter forming data groups including data corresponding to the interleaved symbols, each data group including known data sequences, signaling information, non-systematic RS parity data place holders and MPEG header data place holders; a packet formatter removing the non-systematic RS parity data place holders in the data groups and replacing the MPEG header data place holders in the data groups with Moving Picture Experts Group (MPEG) header data in order to output mobile service data packets; and a second randomizer randomizing the MPEG header data in the mobile service data packets.
摘要:
A method and apparatus is provided for processing broadcast data in a digital broadcast transmitter. The method includes performing Reed-Solomon (RS) encoding and Cyclic Redundancy Check (CRC) encoding on mobile service data to build an RS frame, dividing the RS frame into a plurality of portions, mapping one of the plurality of portions into a first data group that has a first region and a second region and adding known data sequences and place holders for MPEG header data to the first data group, deinterleaving data in the first data group to output a second data group, replacing the place holders for MPEG header data in the second data group with MPEG header data such that mobile service data packets are output and interleaving data in the mobile service data packets.

A digital broadcasting system and method of processing data are disclosed. Herein, a transmitting system within the digital broadcasting system includes a byte-symbol converter, an interleaving unit, a block formatter, and a trellis encoding module. Herein, the byte-symbol converter converts inputted mobile service data to symbol units. The interleaving unit is provided with (N−1) number of block interleavers in parallel, and interleaves the symbols outputted from the byte-symbol converter. The block formatter controls output orders of the mobile service data being inputted and data being outputted from each block interleaver within the interleaving unit. The trellis encoding module is provided with a plurality of trellis encoders in parallel, and enables each trellis encoder trellis-encode the mobile service data.
摘要:
A broadcast receiving system capable of receiving mobile broadcast data and a method for processing broadcast signals are disclosed. The broadcast receiving system includes a first receiving unit, a second receiving unit, a known sequence detector, a equalizer, and a display unit. The first receiving unit receives a first broadcast signal including first mobile broadcast service data and first main broadcast service data. The second receiving unit receives a second broadcast signal including second mobile broadcast service data and second main broadcast service data. The known sequence detector detects at least one of known data included in the received first broadcast signal and known data included in the received second broadcast signal. The channel equalizer uses the detected known data, thereby channel-equalizing the received first and second mobile broadcast service data corresponding to the detected known data. The display unit provides any one of first video data and second video data included in the channel-equalized first and second mobile broadcast service data to a user.

A broadcast receiver and a method of processing broadcast data in the broadcast receiver are disclosed. The broadcast receiver includes a tuner for receiving a broadcast signal including mobile service data, main service data and known data sequences; an equalizer for compensating channel distortion of the broadcast signal using at least one of the known data sequences; a first decoder for decoding the mobile service data in the equalized broadcast signal; and a second decoder for CRC-decoding and RS-decoding the turbo-decoded mobile service data.
