ITU-T H.741.3 (06/2012) i Recommendation ITU-T H.741.3 IPTV application event handling: Audience measurement for IPTV distributed content services Summary The ITU-T H.741.x series of Recommendations defines a foundational plat

9、form 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 ser

10、vices 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

11、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.741.3 specifies audience measurement for IPTV distributed content services and, in particular, linear TV serv

12、ices. It describes specific configuration for linear TV and metadata and data structures used in the payload of AM messages. The informative appendices discuss specific implementation considerations for linear TV-specific implementation considerations, provide examples and describe capabilities and

ITU-T H.741.3 (06/2012) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector

15、 (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 to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every f

16、our 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 Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, t

17、he necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary.

18、 However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance 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 neg

19、ative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the

20、use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendati

21、on, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/

ITU-T H.741.3 (06/2012) 1 Recommendation ITU-T H.741.3 IPTV application event handling: Audience measurement for IPTV distributed content services 1 Scope This Recommendation describes audience measurement for IPTV distributed content services. This includes specific

27、events and samples, configuration and reporting for linear TV services. Subsequent releases will address additional IPTV distributed content services. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions

28、 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 most recent edition of the Recommendations an
