Abstract
A method for improving the data rate of data for M/H receivers and for improving the quality of channel estimation in an ATSC-M/H transport data stream marks the transport data packets determined for the transmission of data for M/H receivers in N (e.g., 38) consecutively transmitted transport data packets in an ATSC-M/H-slot of the uncoded ATSC-M/H transport data stream originally determined for the transmission of data for stationary receivers. Coded data for M/H receivers are inserted in the marked transport data packets and introduce training sequences in segments of data fields of the coded ATSC-M/H transport data stream containing marked transport data packets.
