10、ervices Amendment 1 XML schema on the measurement data structures for linear TV service 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

11、 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 fo

12、r 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 eme

13、rging regulations and legislation. Recommendation ITU-T H.741.3 specifies audience measurement for IPTV distributed content services and, in particular, linear TV services. It describes specific configuration for linear TV and metadata and data structures used in the payload of AM messages. The info

14、rmative appendices discuss specific implementation considerations for linear TV-specific implementation considerations, provide examples and describe capabilities and profiles.

ITU-T H.741.3 (2012)/Amd.1 (02/2015) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized age

18、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

19、 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

20、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

21、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

22、 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

ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, wh

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.

29、 0-1 = optional (maximum one instance), 0-* = (optional and multiple instances possible), 1-* = mandatory and multiple instances possible) Type: string, integer, float, etc. Container: elements are defined to group associated elements In the following tables containing data structures, an alternativ

30、e representation may be shown which illustrates the data structure. In the event of discrepancy between an alternative representation and the table, the correct information is to be found in the table. Table 1 summarizes audience measurement elements for linear TV. Table 1 Audience measurement eleme

31、nts for linear TV Element Definition Type Notes or value domain ServiceInstanceID Identifies the instance of a specific service. Distinguishes among services when multiple services are displayed. Defined in ITU-T H.741.2 ServiceIdentifier Contains the “unique name for the service within the service

32、providers domain“ (according to ITU-T H.770) which starts to be received. NOTE Defined in ITU-T H.770 with the encoding in Figure 3. ChannelChangeFilter Reports channel start and channel stop events only when the time following an event, without either subsequent event occurring, is greater than Cha

33、nnelChangeFilter ms. xs:integer Values: time in milliseconds, 0 means report all channel start and channel stop events. NOTE This sets the minimum time to report latency for channel start and channel stop events, to at least the specified time in milliseconds. ControlDevice Indicates the device type

Figure 3 XML encoding for ServiceIde

38、ntifier in linear TV audience measurement ViewMode is an element to identify how the channel being received is rendered on the terminal device when started. The display modes are listed below: Full screen (means that only the linear TV video is displayed, independent of the percentage of the display

39、 covered by the video). Rec. ITU-T H.741.3 (2012)/Amd.1 (02/2015) 3 Picture-in-picture (means a second service is displayed over a small part of the display of the main service. Sound is usually from the main service only). Mosaic (in which many linear TV channels are received and displayed simultan

40、eously in the same format as a matrix of small TV screens). Other includes presentation of video in other modes. Table 2 provides information regarding events which are specific to the linear service. Table 2 Types of linear TV events Event Definition Notes or value domain Linear ChannelStart This e

41、vent occurs when a user starts watching a TV channel or switches to another TV channel for which AM reporting is authorized by the user and configured to be reported about by the SP. It causes reporting of the ChannelStart data structure defined in Table 6. Linear ChannelStop This event occurs: 1) w

42、hen a user stops watching a linear TV service without starting another linear TV service; 2) when a user switches to another channel for which reporting is forbidden by the user or is configured not to be reported about by the service provide (SP); 3) when the content of a specified class starts pla

43、ying although it is forbidden to be measured by the user or configured not to be measured by the SP; 4) following restoration from a communications loss to indicate the time at which a channel was no longer being received; 5) when it causes reporting of the ChannelStop data structure defined in Tabl

44、e 6. This event may also occur during channel change filtering. NOTE An example of case 5 is when an AM operation is restored following power-down. When a measurement request includes LinearTVQualifier, and is configured with EventTrigger, then the events LinearChannelStart and LinearChannelStop are

45、 by default included in the events to be measured and reported, having the highest priority. The sample set identifiers in Table 3 are used to indicate elements to be reported when scheduled time sampling is used.
