10、nder, and age of persons in front of camera, by processing video data captured by camera. Recommendation ITU-T H.742.0 describes an architecture and the requirements of IPTV application events extracted by video sensor devices. The requirements cover general functionalities, delivery mechanisms, met
11、adata, and functions to avoid the risk of privacy infringement.

13、(ITU) is the United 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
14、issuing Recommendations 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
15、 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, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expres
16、sion “Administration“ 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 applicabil
17、ity) 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 negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Re
18、commendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU 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
19、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 Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this
20、 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:/www.itu.int/ITU-T/ipr/.

26、ation events extracted by video sensor devices. It describes an architecture and the requirements for general functionalities, delivery mechanisms, metadata, and functions to avoid the risks of privacy infringement. 2 References The following ITU-T Recommendations and other references contain provis

31、 Terms defined elsewhere This Recommendation uses the following terms defined elsewhere: 3.1.1 aggregation function ITU-T H.741.0: The function that configure audience management functions (AMFs), then receives processed events, sample values and end-user information from AMFs. It may participate in
32、 the communication of end-user permissions. 3.1.2 application b-ITU-T Y.101: A structured set of capabilities, which provide value-added functionality supported by one or more services. 3.1.3 application event b-ITU-T H.740: An application event is every end-user interaction or occurrence related wi
33、th multimedia contents in IPTV applications. It includes an emergency event from event notification services 3.1.4 audience measurement ITU-T H.741.0: The measurement of peoples engagement with IPTV services. 3.1.5 audience measurement data ITU-T H.741.0: End-user behaviour data which is related to
34、a service and content consumption, combined or not with end-user information. 3.1.6 audience measurement function (AMF) ITU-T H.741.0: The function that, if given permission, measures the end-user behaviour by processing events or samples from IPTV services. 2 Rec. ITU-T H.742.0 (07/2016) AMFs may r
35、equest and collect end-user information. AMFs transfer processed events, samples and end-user information to aggregation functions. 3.1.7 content provider ITU-T Y.1910: The entity that owns or is licensed to sell content or content assets. 3.1.8 delivery ITU-T Y.1910: In the context of IPTV architec
36、ture, “delivery“ is defined as sending contents to the end user. 3.1.9 digital signage b-ITU-T H.780: A system that sends information, advertising and other messages to electronic devices (e.g., displays, speakers) in accordance with the time of day and the location of the display, or the actions of
37、 audience. Contents and their relevant information, such as display schedules, are delivered over networks. 3.1.10 end user ITU-T Y.1910: The actual user of the products or services. NOTE The end user consumes the product or service. An end user can optionally be a subscriber. 3.1.11 IPTV ITU-T Y.19
38、01: Multimedia services such as television/video/audio/text/graphics /data delivered over IP-based networks managed to support the required level of QoS/QoE, security, interactivity and reliability. 3.1.12 metadata ITU-T Y.1901: Structured, encoded data that describe characteristics of information-b
39、earing entities to aid in the identification, discovery, assessment, and management of the described entities. NOTE EPG metadata has 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 different
40、scenes in a movie or providing business rules detailing how the content package may be displayed, copied, or sold. 3.2.13 network provider ITU-T Y.1910: The organization that maintains and operates the network components required for IPTV functionality. NOTE 1 A network provider can optionally also
41、act as service provider. NOTE 2 Although considered as two separate entities, the service provider and the network provider can optionally be one organizational entity. 3.1.14 privacy b-ITU-T X.800: The right of individuals to control or influence what information related to them may be collected an
42、d stored and by whom and to whom that information may be disclosed. NOTE Because this term relates to the right of individuals, it cannot be very precise and its use should be avoided except as a motivation for requiring security. 3.1.15 service b-ITU-T Y.101: A structure set of capabilities intende
43、d to support applications. 3.1.16 service provider b-ITU-T M.1400: A general reference to an operator that provides telecommunication services to customers and other end users either on a tariff or contract basis. A service provider may or may not operate a network. A service provider may or may not
44、 be a customer of another service provider. 3.2 Terms defined in this Recommendation This Recommendation defines the following terms: 3.2.1 video data: A set of digital images captured by a camera. A digital image is a numeric representation of a two-dimensional image. 3.2.2 video sensor: A device t
45、hat has image processing ability, such as image compression, image manipulation with the video data captured by a camera. A video sensor can generate video sensor information alone, by processing video data when it has enough computational power. Otherwise, some functions of the video sensor are pro
46、cessed through external systems and the video sensor generates intermediate video sensor information. Rec. ITU-T H.742.0 (07/2016) 3 3.2.3 video sensor information: Extracted and derived information from video data, for example, emotion, number, gender, and age of persons, or movement. 4 Abbreviatio
47、ns and acronyms This Recommendation uses the following abbreviations and acronyms: AMF Audience measurement function EPG Electronic program guide IP Internet protocol IPTV Internet protocol television QoE Quality of experience QoS Quality of service SP Service provider STB Set-top box TV Television
48、UVS Use of video sensor devices VSI Video sensor information WAN Wide area network 5 Conventions In this Recommendation: The keywords “is required to“ indicate a requirement which must be strictly followed and from which no deviation is permitted, if conformance to this Recommendation is to be claim
49、ed. 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 keywords “can optionally“ indicate an optional requirement which is permissible, without implying any sense of being recommended. This term is not intended to imply that the vendors implementation must provide the option, and the feature can be optionally enabled by the network operator/se
