Hello detlef,
The PID should be come from MPEG standard,the header ofTransport stream (TS) packetsinclude such information.
For example, somesescription like
the PID is 13-bit value used to identify multi-plexed packets with mpeg2-TS.
most of decoder of TSshould can read such information or set it during produce a TS.

I can add the language code to AudioStreamInfo, but creation of description lines is an application-level task.
