Abstract:
1. A digital television (DTV) transmitting system for processing digital broadcast data, the DTV transmitting system comprising: a first randomizer for randomizing enhanced data; an encoder for Reed-Solomon (RS) encoding and Cyclic Redundancy Check (CRC) encoding the randomized enhanced data to build an RS frame; a block processor for encoding data in the RS frame at a code rate of 1/H, wherein H is greater than 1; a group formatting unit for: a packet formatter for removing the RS parity data place holders in the data groups in which data is deinterleaved and replacing the MPEG header data place holders with MPEG header data in the data groups in which data is deinterleaved to output enhanced data packets; a second randomizer for randomizing the MPEG header data in the enhanced data packets; and an interleaver for interleaving data in the enhanced data packets having the randomized MPEG header data.
