Hi,

Would it be possible to see some of the ATSC papers on this subject? It would indeed be good to have a single solution. Please join the reflector and submit your proposals and we will determine the reaction.

    Martin:
                 I read your e-mail with interest. Would it possible 
for  the IETF BoF to widen its focus to IP over ATSC as well ?
The  ATSC T3/S13 Data Broadcast Specialist Group that I 
chair  has just released a specification in which we solved a 
number  of problems related to the mapping of IP networks 
into  an MPEG-2 Transport Stream. We also have defined  
how  SAP/SDP and ATSC PSIP (the counterpart of DVB-SI)
can  coexist and complement each other. Finally we have 
had a  close cooperation with the US cable industry in this 
matter  (DVS 311).  Please let me know. 
 
                 Thank you in advance.

Subject: Proposed IETF BoF on IP over DVB - an  explaination!


Dear All,  

After some discussions the job of  introducing this topic fell on me.. here goes. 


Proposed IETF  BoF on IP over DVB - an  explaination! 
------------------------------------------------------    ------------------------ 

Background 
------------------ 

With the  new direction of DVB 2.0 which has IP as a main element, certain activies have  been started within DVB. Issues with IP have been raised and many have now  found owner groups. Some issues have not. In some cases expertise on issues  has not been available within the groups within DVB. 

At the last TM meeting a call for remaining technical  issues was made and these are to be debated at the next meeing in November,  this clearly needs to happen and the following is in no way intended to  conflict with this. 

The issue  concerning the carriage of IP over DVB have also been raised in the DVB-BSS  group. 

It has been noted that DVB  has forged good liasons with various external bodies to promote information  exchange and the question has been posed by several DVB members about liason  with the IETF to ensure that effort is not duplicated, expertise is available  and that good visibility of issues is achieved. 

One problem with the IETF is that it does not readily  support such liasons except those formed by the attendees. Thus for any  successful liason to occur it is important that DVB members have  representation within the IETF and vica versa. 

It came to light in the discussions within the DVB-IPI  group that the PILC (Performance Implications of link Characteristics) group  within the IETF had been studying transport of IP over links such as MPEG and  DVB. Several organisation who are also DVB members were also active in the  IETF and concerned about the commercial and technical impliciations of the  convergence of DVB/MPEG and IP networks. Mr Gorry Fairhurst of Aberdeen  University (who had presented work in this group within the IETF)   undertook to explore how these issues could best be tackled within both  DVB and IETF. 

The question was how  to get a group within the IETF that could best discuss the issues surrounding  DVB/MPEG in a similar way to those tackling ATM, Mobile, Bluetooth etc.  

How to Create an IETF working  group 
-------------------------------------------------------  

The road to creating an IETF group starts  with finding a group of people interested in a topic. 
  
         First one needs to have an issue. 
        This needs to be discussed  with an Area Director - e.g. Internet , Applications, General, Operations,  Routing, Security, Sub IP etc. 
         Sufficient interest has to be demonstrated  
        A proposal  for a group  at an IETF meeting 
                - This is known  as a BoF which stands for 'Birds or a Feather' ( for those not familiar this  is a saying 'Birds of a Feather Flock Together') 
        The BoF meets - if  sufficient people attend the group and a report is generated the BoF turns  into a working group (or else it dies!). 


Current Status 
--------------------- 

Gorry  has a proposal with the relevant Area Director for a BoF to be held at the  next IETF meeting in Salt Lake City (10-14 Dec 2001). He has created a  temporary email reflector (ip-dvb@erg.abdn.ac.uk) to discuss the formation of  this group and several DVB members have subscribed. 

A decision needs to be taken soon as to:-  

        Is there  enough support within DVB for such an activity? 
        Is there any opposition to  this activity within DVB? 
         Is the December IETF meeting too soon or should this be  postponed to Minneapolis in March? 

There is no desire to push for an activity that will not have enough  support and therefore not achieve the status of a working group.  

Action Required 
------------------------ 

DVB members interested in this topic and capable of  attending the IETF in either December or March and interested in the proposed  BoF should contact Mr Gorry Fairhurst gorry@erg.abdn.ac.uk and/or  subscribe to the email reflector ip-dvb@erg.abdn.ac.uk
