@start absent, previous Period has @duration: previous start plus previous duration.
@start absent, first Period of a static MPD: 0.
@start absent, first Period or previous without @duration, dynamic MPD: Early Available Period (no PeriodStart yet).
@duration present and (the next Period has @start or MPD@minimumUpdatePeriod exists): Early Terminated Period.
