Summary
The ITU-T H.741.x series of
Recommendations defines a foundational platform for audience measurement (AM)
of IPTV services. They focus on the interface between terminal devices and an
audience measurement aggregation function.
The AM platform integrates a method for
end users to report personal information, and is designed to easily add
time-shifted and interactive services, and non-terminal device measurement points.
While the ITU-T H.741.x series allows the implementation of audience
measurement for IPTV services, its mechanism may be equally applicable to
non-IPTV services.
The design philosophy in the ITU-T
H.741.x series is focused on scalability, minimizing the use of resources,
security, flexibility to support a variety of service-provider deployments,
and rich privacy support to meet emerging regulations and legislation.
Recommendation ITU-T H.741.4 specifies
the data elements and structures of the transport delivery-dependent XML and
binary headers, used in audience measurement messages. Appendix I
provides an analysis of AM to understand its transport protocol requirements.
Amendment 1 to Recommendation ITU-T H.741.4
includes XML schema on the data structures for message delivery in Annex A.
