HI every body,
i've read all the archive paper, but every time i found i misunderstood,
what the writer would say.
I hope some one to present clear simple explanation of:
-> the steps to do from an IP paquet to MPEG2 TS.
for example:
       |ip paquet(1500 bytes for example)|
			|
			|
       |encapsulated in What ?|
                        |
  			|
			?
			|
	|MPEG TS| + |MPEG TS| +|MPEG TS| + ..

another question: i've read that "we can map IP Networks to PID", but in
multicasting how we can do that, we don't have a netword adress, as i
know..!?
Thank you and seeu.
