    摘要: A digital broadcast transmitting and a method of processing broadcast data in a digital broadcast transmitting system are disclosed. The method includes randomizing mobile service data; RS encoding and CRC encoding the randomized mobile service data to build an RS frame; dividing the built RS frame into L (L>1) number of portions and adding K bytes (K≧0) of dummy data to one of the portions; encoding data in the portions at a code rate of 1/H (H>1); first interleaving the encoded data; mapping the first interleaved data into data groups and adding known data sequences and transmission parameters to each of the data groups, deinterleaving data of the data groups; second interleaving the deinterleaved data; and transmitting a transmission frame including the second interleaved data.

    摘要: An apparatus and method for processing digital broadcast signal are provided. The method for processing a broadcast signal includes forming a data group having mobile broadcast service data, where forming the data group includes mapping the mobile broadcast service data into corresponding locations of the data group, adding known data sequences and signaling data into the data group, inserting place holder bytes for MPEG header and non-systematic Reed-Solomon (RS) parity, and de-interleaving data of the data group having the mobile broadcast service data, known data sequences, signaling data and place holder bytes, and formatting mobile broadcast service data packets including the de-interleaved data of the data group, where formatting the mobile broadcast service data packets includes removing place holder bytes for the non-systematic RS parity, and replacing place holder bytes for the MPEG header with the MPEG header.

    摘要: A transmitting system, a receiving system, and a method of processing broadcast signals are disclosed. Herein, the transmitting system includes an RS frame encoder, a block processor, a group formatter, and a trellis encoding module. The RS frame encoder performs error correction encoding on an RS frame payload including mobile service data so as to form an RS frame, divides the RS frame into a plurality of portions, and outputs the divided RS frame portions. The block processor performs one of ½-rate encoding and ¼-rate encoding on each bit of the mobile service data included in each portion. The group formatter maps a portion including symbols of the ¼-rate encoded mobile service data and symbols of the ½-rate encoded mobile service data to a corresponding region of a data group. And, the trellis encoding module performs trellis encoding on the symbols of the ¼-rate encoded mobile service data and the symbols of the ½-rate encoded mobile service data of the data group.
