[Mp4-tech] [MPEG2 Transport] How to find out Number of substrem under private stream 1 in case of TS

[raj sekhar]

Hi List,
   I am working on MPEG2 Transport layer. Im working on Program streams
stored in DVDs.
   I want to convert the Program stream from DVDs to transport streams and
then stream those
   Transport streams. Now I want to know how many substreams are there under
Private Stream 1.
   Program Stream Map in case of Program streams provide this information.
  How to get Program Stream Map information while converting PS to TS
without parsing the PS. Is the Program Stream
  Map is necessary in case of Program Streams? If it is not present in PS
then how to get that information while converting
  to TS?
Thanks in advance-
Rajasekhar
