For Your info: ATSC A92

[Gorry Fairhurst <gorry@erg.abdn.ac.uk>]

I thought it would be useful to draw to our attention the
recent addition of ATSC A92 - dealing with IP  multicas,
although the document seems only to address IPv4, and only
addresses use of DSMCC.

Comments on relevance or otherwise and technical issues
will be welcome.

I have uploaded a recent ATSC document for reference.

ATSC Standard: A92
Delivery of IP Multicast Sessions over ATSC Data Broadcast
31 January 2002

This standard specifies the delivery of IP Multicast sessions, the delivery
of data for describing the characteristics of a session, and usage of the
ATSC A/90 Data Broadcast Standard for IP Multicast.

This document defines a Standard for the asynchronous transmission of
Internet Protocols (IP) specifically including multicast addressing
compatible with the ATSC A/90 Data Broadcast Standard. This Standard assumes
the use of Session Description Protocol (SDP) as an integral
part of the IP Multicast-based Data Broadcast service. It is strongly
suggested that normative clauses that do not directly involve SDP be
retained in the case of IP Multicast-based Data Broadcast services that do
not include any SDP data, such as would be used for non-sessionbased IP
Multicast. This document focuses solely on the carriage of all information
using the DSMCC_addressable_section. Synchronous and synchronized carriage
of IP Multicast datagrams are not addressed by this document.
