3.7.4 The Continuity Counter
Each transport stream packet with the same PID carries its own 4-bit
counter. This is the continuity counter which continuously counts from 0 -
15 from TS packet to TS packet and then begins again from 0. The conti-
nuity counter makes it possible to recognize missing TS packets and to
identify an errored data stream (counter discontinuity). It is possible, and
permissible, to have a discontinuity with a program change which is then
indicated by the Discontinuity Indicator in the adaptation field.
