   Address Acquisition For Multicast Content When Source and Receiver
                     Support Differing IP Versions
             draft-ietf-mboned-multrans-addr-acquisition-07

Abstract

   Each IPTV operator has their own arrangements for pre-provisioning
   program information including addresses of the multicast groups
   corresponding to broadcast programs on the subscriber receiver.
   During the transition from IPv4 to IPv6, scenarios can occur where
   the IP version supported by the receiver differs from that supported
   by the source.  This memo examines what has to be done to allow the
   receiver to acquire multicast address information in the version it
   supports in such scenarios.

1.  Introduction

   In the case of broadcast delivery of program content, the operation
   of viewing a program follows a well-defined sequence.  For the sake
   of reducing channel switching delay, the list of multicast addresses
   is generally pre-provisioned to the receiver as part of the program
   guide.  Each operator has their own solution for achieving this
   delivery, despite the attempts at standardization recounted in
   Appendix A.

   At some later time, after the program guide is delivered, the user
   chooses to view a program, possibly by selecting it from a displayed
   program listing, or simply by selecting a channel.  The receiver uses
   its pre-acquired information to signal to the network to receive the
   desired content.  In particular, the receiver initiates reception of
   multicast content using the multicast group address and possibly a
