Abstract:
1. An ATSC-MH broadcasting signal re-generating module comprising: a slot gatheror for gathering a slot data comprising 118 consecutive packets of an identical PID supposing valid 118 MHE packets from main stream data generated by a de-randomizer of a main stream data generating module by receiving ATSC-MH RF signal including MHE packets regarded as null packets; a modified-randomizer for modified-randomizing the 118 consecutive packets of an identical PID; an RS encoder for RS-encoding data after the modified-randomizer; a modified-data interleaver for modified-data interleaving data after the RS encoder; a signaling data extracting means for extracting signaling data from an output buffer of the modified-data interleaver; and a group format detecting means for discriminating whether or not the 118 consecutive packets of an identical PID are enough to be adopted as valid 118 MHE packets according to validity or non-validity of the signaling data, and outputting data of MPH Group format after data interleaver reconfigured from the 118 consecutive packets of an identical PID when the signaling data is valid.
