Hi john332,
Can you share that transport stream which is carrying ECM and EMM.?

and also
if possible can u explain,
how SAS (Subscriber Authorization System), SMS (Subscriber Management System) prepares EMM ?

How EMM organized? what actually it contains?

what is the relation between EMM and Smart Card?

Thanks in Advance
