For monitoring synchronization to the MPEG2 transport stream, a sync
hysteresis can be generated separately for sync lock and sync loss. The sync
hysteresis specifies the number of successive valid/invalid sync words received
before the measurement decoder identifies a sync lock (TS SYNC LOCK) or
sync loss (TS SYNC LOSS).
LOCK Number of valid sync words before TS SYNC LOCK is
recognized, selectable between 1 and 31
LOSS Number of invalid sync words before a TS SYNC LOSS is
recognized, selectable between 1 and 7
