摘要:
A service multiplexer of a digital broadcasting system includes a null data generator, a mobile service multiplexer, a main service multiplexer, and a multiplexer. The null data generator may generate null data. The mobile service multiplexer may multiplex and output compression encoded mobile service data, additional data for a mobile service, and null data at a pre-determined first data rate. The main service multiplexer may multiplex and output compression encoded main service data and additional data for a main service at a pre-determined second data rate. The multiplexer may multiplex the output data of the main service multiplexer and the output data of the mobile service multiplexer at a pre-determined third data rate and transmitting the multiplexed data to at least one transmitter located at a remote position.

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 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 method of processing broadcast data includes performing RS (Reed-Solomon) encoding and CRC (Cyclic Redundancy Check) encoding on mobile service data to output an RS frame; dividing the RS frame into a plurality of portions; block processing data in one portion of the plurality of portions; mapping the block processed data in the one portion into at least one region of a data group that comprises a plurality of regions, and adding a first known data sequence, a plurality of second known data sequences, and a transmission parameter to the data group; and transmitting a transmission frame including the data group, wherein the transmission parameter is positioned between the first known data sequence and one of the plurality of second known data sequences, and the first known data sequence and the one of the plurality of second known data sequences differ from each other in length.
摘要:
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.

摘要:
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.
