Gorry: I would like to invite this group to consider opening the charter to not only DVB Transport Streams but also to ATSC Transport Streams and in general, to MPEG-2 Transport Streams. Carriage of IP in ATSC Transport streams is specified in the ATSC A/90 standard published last year. Carriage of IP in MPEG-2 Transport streams is specified by Amendment 1 to MPEG-2 DSM-CC published late last year. One of the benefits of expanding the scope of the work would be to take into account some of the work that has already been done in this area. The ATSC Data Broadcast Specialist Group that I chair has produced a specification that goes over some the items that have been brought up, namely: Mapping of IP networks to an MPEG-2 Transport stream, coexistence of SAP/SDP with SI information, Management of local network interfaces, discovery of IP Multicast address for filtering purpose. We have also coordinated this effort with SCTE. I have attached a copy of this draft specification. It is in an advanced stage since we have just completed the disposition of the second ballot comments. Thank you in advance. Kind regards, Regis J.

Following comments from the list, I have issued a revised proposed charter. This is to be found at: http://www.erg.abdn.ac.uk/users/gorry/ip-dvb/charter.html It's now time to assess whether **WE** feel there is sufficient progress to start writing protocol documents, and therefore request that the IETF should consider a BoF, with a view to forming a WG on this subject. Please read the following, and complete the information below and return it to me directly. I will use the number and enthusiasm of the responses as an indicator of how this discussion is progressing. I shall summarise the answers to this list. Best wishes, Gorry ------------ Please return form below to: gorry@erg.abdn.ac.uk [ ] I agree with the proposed charter [ ] I would like the proposed charter to be changed to consider the following issues: .................................................................. ----- [ ] I shall be attending the next IETF and would like to see a BoF on this topic [ ] I would like to present a short presentation at a BoF on this topic ----- I am interested in co-authoring/editing an Internet Draft on [ ] Requirements for IP over DVB [ ] Efficient Encapsulation for IP over DVB [ ] DVB Address Resolution for IP over DVB [ ] Multicast Support for IP over DVB [ ] Other ..................................................................
