ITU-T H.741.4 (06/2012) i Recommendation ITU-T H.741.4 IPTV application event handling: Transport mechanisms for audience measurement Summary The ITU-T H.741.x series of Recommendations defines a foundational platform for audience measurem
9、ent (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 de
10、vice 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, sec
11、urity, 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 measure
12、ment messages. Appendix I provides an analysis of AM to understand its transport protocol requirements.

ITU-T H.741.4 (06/2012) FOREWORD The International Telecommunication Union (ITU) is the Unit
14、ed Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommend
15、ations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The appr
16、oval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administrat
17、ion“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and complian
18、ce with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is r
19、equired of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intel
20、lectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation.

26、cribes transport mechanisms for audience measurement (AM). It specifies how the data structures defined in ITU-T H.741.2 and ITU-T H.741.3 are exchanged over different transport protocols. The term transport protocol as used in this Recommendation refers to the protocol in which AM messages are enca
27、psulated for delivery to a remote device. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation. At the time of publication, the editions indicated were valid. All Recommendations a

The keywords “is required to“ indicate a requirement which must be strictly followed and from which no deviation is permitted if conformance to th
47、is Recommendation is to be claimed. The keywords “is recommended“ indicate a requirement which is recommended but which is not absolutely required. Thus this requirement need not be present to claim conformance. The keyword “is not recommended“ indicate a requirement which is not recommended but whi
48、ch is not specifically prohibited. Thus, conformance with this specification can still be claimed even if this requirement is present. The keywords “can optionally“ indicate an optional requirement which is permissible, without implying any sense of being recommended. This term is not intended to im
49、ply that the vendors implementation must provide the option and the feature can be optionally enabled by the network operator/service provider. Rather, it means that the vendor may optionally provide the feature and still claim conformance with the specification. The keyword “functions“ is defined as a collection of functionalities. It is represented by the following symbol in the context of IPTV architecture: The keywords “functional block“ is defined as a group of functionalities th
