The sgmParse.pl Utility
The sgmParse.pl utility can be used to read the service group map file. Service group
map files contain all of the frequencies, transport stream identifiers (TSIDs), and
modulation types that are assigned to a service group on gigabit quadrature
amplitude modulation (GQAM) and multiple QAM (MQAM) modulators.
