    摘要： A method of processing digital broadcast data in a digital broadcast transmitter includes performing Reed-Solomon (RS) encoding and Cyclic Redundancy Check 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 and inserting known data sequences, transmission parameters, place holders for non-systematic RS parity data, place holders for main service data, and place holders for MPEG header data into the first data group; deinterleaving data of the first data group to output a second data group; and removing the place holders for non-systematic RS parity data and the place holders for main service data in the second data group and replacing the place holders for MPEG header data in the second data group with MPEG header data to output mobile service data packets.

    摘要： A digital broadcasting system and a data processing method 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. The data processing method of a digital broadcast transmitting system includes the steps of forming a RS frame by grouping a plurality of mobile service data bytes that is being inputted, and performing error correction encoding in RS frame units, forming a super frame by grouping a plurality of the error correction encoded RS frame, performing row permutation in super frame units, and dividing the super frame back to RS frames, and dividing the RS frame into a plurality of data groups.

    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. The method of processing data in a transmitting system includes receiving mobile service data, encapsulating the received mobile service data to a transport stream (TS) packet, and outputting the encapsulated mobile service data as a mobile service data packet, and multiplexing a main service data packet including main service data and the encapsulated mobile service data packet, thereby transmitting the multiplexed data packets to at least one transmitter located in a remote site.
