1	Overview

OMA BAC-BCAST has a question to IETF RMT on the stability of standards-track
evolution of 'Layered Coding Transport (LCT) Building Block'. The latest
Internet-Draft revision -04 (expired) of LCT introduced the header extension
EXT_TIME for the purpose of signalling time stamps of different nature. OMA
BAC-BCAST would be interested to use that method but is hesitant to refer to
ongoing IETF work unless such work can be considered stable. Our concrete
questions are: 

1.	Does IETF RMT consider the revision of LCT building block stable enough so
that we can refer to that in OMA BCAST 1.0 specification?

2.	What is estimated schedule for revising the RMT RFCs on the Standards

2	Requested Action(s)
OMA BAC-BCAST requests IETF RMT to provide guidance on the two questions
presented in this liaison.

3	Conclusion

We thank you for your consideration.

With best regards, 
(Mobile Broadcast Services sub working group)
