ITU-T H.741.2 (06/2012) i Recommendation ITU-T H.741.2 IPTV application event handling: Data structures of audience measurement for IPTV services Summary The ITU-T H.741.x series of Recommendations defines a foundational platfo
9、rm 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 servi
10、ces, 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 t
11、he 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.741.2 specifies the data elements and structures of the payloads used in audience measurement messages. Histo

ITU-T H.741.2 (06/2012) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (
14、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 to standardizing telecommunications on a worldwide basis. The World Telecommunicati
15、on 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 Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of inf
16、ormation 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 conciseness to indicate both a telecommunication administration and a recognized operating ag
17、ency. 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 is achieved when all of these mandatory provisions are met. The words “shall“ or so
18、me 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. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or
19、 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, whether asserted by ITU members or others outside of the Recommendation development p
20、rocess. 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.

NOTE In some traditional broadcast services, EPG is defined as an on-screen guide used to display information on scheduled live broadcast television programmes, allowing a viewer to navigate, select, and discover programmes by ti
41、me, title, channel, and genre. This traditional definition does not cover “catalogues“ for on-demand and download services (sometimes called electronic content guide or broadband content guide) and bi-directional interactive service (sometimes called interactive programme guide) for end-user interac

47、elevision service in which a continuous stream flows in real time from the service provider to the terminal device and where the end user cannot control the temporal order in which contents are viewed. 3.1.20 metadata b-ITU-T Y.1901: Structured, encoded data that describe characteristics of informat
48、ion-bearing entities to aid in the identification, discovery, assessment, and management of the described entities. NOTE EPG metadata have many applications and may vary in depth from merely identifying the content package title or information to populate an EPG, to providing a complete index of dif
