At the moment there are a number of ways that IP datagrams are carried, over MPEG-2 Transport Stream. Most practical implementations use varients of the Multi-Protocol Encapsulation (MPE). But this allows various options. There is as yet single recommended method. You'll find much discussion of this on the ip-dvb list, web site at http://www.erg.abdn.ac.uk/users/gorry/ip-dvb including one specific submission at: http://www.erg.abdn.ac.uk/users/gorry/ip-dvb/docs/Overhead-Analysis.doc There's a mailing list on IP over MPEG-2 (and DVB/ATSC/etc.) which would be a good place to answer this question. The ip-dvb list is NOT an IETF working group, but has been proposed for a BOF to the IESG to start work in this area. Details of how to join the list can be found at the above web site.
