*-------------------------------------------------------------------------------
* The C_TsMux is a class which can select one or more programs of a TS stream.
*
* First it has to be attached to a TS demultiplexer (C_TsDemux) by calling
* the "Attach" method. The "Detach" method is called to reset the multiplexer.
*
* The "AttachProgram" method selects the whole program identified by its
* program_number and its PMT_PID.
* The "DetachProgram" method unselects the whole program identified by its
* PMT_PID.
*
* The multiplexer sends the stream to an object which should implement the
* I_TsPacketHandler interface. The PAT of the whole stream is generated
* so that the stream is valid on the MPEG2 view point.
*
* The C_TsMuxPmtDecoder class is used internally by a C_TsMux object.
