Abstract: A method of processing broadcast data includes: performing RS encoding and CRC encoding on mobile service data to generate an RS frame belonging to an ensemble including a signaling information table including access information of the mobile service data and identification information for identifying a stream where keys to decrypt the mobile service data are obtained; mapping a portion of data in the RS frame to a group including known data sequences, FIC data, and TPC data, wherein the FIC data includes information for rapid mobile service acquisition, and the TPC data includes FIC version information for indicating an update of the FIC data; and transmitting a broadcast signal including the group. The group further includes data blocks. First, fourth, fifth and sixth known data sequences are inserted into third, fifth, sixth and seventh data blocks, respectively. Second and third known data sequences are inserted into a fourth data block.

Abstract: A transmitting system and a method for processing data are disclosed herein. The transmitting system includes a service multiplexer and at least one transmitter located in a remote position from the service multiplexer. Herein, the service multiplexer generates an RS frame having the size of N (row)×187 (column) bytes including at least one type of mobile service data, packetizes the RS frame into a plurality of mobile service data packets, and multiplexes the packetized mobile service data packets with a main service data packet at a predetermined data rate, thereby transmitting the multiplexed data packets. Herein, each mobile service data packet is configured of a TS header and a data region, and the data region is configured of at least one of a payload region and an adaptation field region.
