* Datastructures for working PID/integer lists
|
||
*
|
||
* The PAT is adequately represented by a transport_stream_id and a
|
||
* pidint_list of its program_number->PID mappings.
|
||
*
|
||
* A PMT requires a bit more structure, mainly to allow for the handling
|
||
* of descriptor information.
