Patent ID: 8774069

Claim:
A method for mapping data packets of a first data stream into data fields of a second data stream at several transmitters, comprising: generating a first data stream with first data packets containing data associated with stationary receivers and second data packets containing data associated with mobile receivers in a head-end, whereby second data packets at the start of a group of consecutively transmitted second data packets contain specific dummy bytes into which signaling information is filled; transmitting said first data stream from said head-end to each of said transmitters; extracting, by each transmitter, said signaling information from said second data packets indicating in which data slot and in which data sub-frame of a received data frame said second data packet is transferred; inserting, by each transmitter, synchronization data in a specific data packet in each data slot containing second data packets; and mapping said first and second data packets consecutively into said second data stream, wherein a number of received second data packets of an ATSC-M/H group is checked for completeness using a continuity counter in a header of each second data packet, and wherein a number of second data packets containing a dummy data packet is inserted in said data slot corresponding to the number of lost second data packets in an ATSC-M/H group of said data slot.
