ITU-T H.741.1 (06/2012) i Recommendation ITU-T H.741.1 IPTV application event handling: Audience measurement operations for IPTV services Summary The ITU-T H.741.x series of Recommendations defines a foundational platform for audience
9、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-ter
10、minal 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 resour
11、ces, security, flexibility to support a variety of service provider deployments, and rich privacy support to meet emerging regulations and legislation. Recommendation ITU-T H.741.1 specifies the operations of AM, including procedures prior to configuration of terminals, configuration of terminals, r
12、eporting by terminals, security mechanisms, and recovery from abnormal situations. Informative Appendices I-VII discuss discovery metadata, implementation considerations, examples, permission levels, vendor considerations, alternative privacy schemes, and discuss capabilities and profiles.

ITU-T H.741.1 (06/2012) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized age
16、ncy 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 Recommendations on them with a view
17、 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 approval of ITU-T Recommendati
18、ons 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 “Administration“ is used for concisene
19、ss 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 compliance with the Recommendation
20、 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 required of any party. INTE
21、LLECTUAL 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 Intellectual Property Rights, w
22、hether 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. However, implementers are

ITU-T H.741.1 (06/2012) 1 Recommendation ITU-T H.741.1 IPTV application event handling: Audience measurement operations for IPTV services 1 Scope This Recommendation describes the operational aspects of audience measurement for
34、IPTV services. It specifies the discovery, configuration, reporting, error handling, and security aspects for IPTV audience measurement. Audience measurements are constrained to the communications interface(s) between terminal device audience measurement functions and measurement aggregation functio
35、ns. Subsequent Recommendations are anticipated to address communications interface(s) with audience measurement functions located within other functions of the IPTV architecture see ITU-T H.741.0. 2 References The following ITU-T Recommendations and other references contain provisions which, through
36、 reference in this text, constitute provisions of this Recommendation. At the time of publication, the editions indicated were valid. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the
37、 most recent edition of the Recommendations and other references listed below. A list of the currently valid ITU-T Recommendations is regularly published.
