    摘要: 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.

    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.
