<p>PDC Label Update Flag (only transmitted in Teletext packets). When this flag is set, the PID is intended to update VCR memory, it does not refer to the current program. According to the examples in EN 300 231 Annex E.3 however VCRs should probably also handle the PID as if a <code>VBI_PIL_INHIBIT_TERMINATE</code> service code was transmitted.</p>
<p>This flag is used to announce a new PIL for the current program. The CNI may refer to a different network than the one transmitting the PID, for example when a program is about to overrun and will continue on a different network. If a program is postponed and no transmission time has been decided yet the new PIL may contain an arbitrary or unreal time. </p>
