ITU-T H.770 (04/2015) i Recommendation ITU-T H.770 Mechanisms for service discovery and selection for IPTV services Summary Recommendation ITU-T H.770 describes the mechanisms for service provider discovery, service discovery and selection for Internet protocol television (IPTV) servic
10、es. The mechanisms enable IPTV terminal devices to provide the end-users with effective ways for consuming IPTV services. The expected types of IPTV services using service discovery information include linear television (TV), video on demand (VoD), etc. This Recommendation identifies service discove
11、ry metadata elements and attributes providing information concerning service providers and contents/services, and its delivery protocols covering both unicast and multicast transport mechanisms. This 2015 edition of the Recommendation adds notes on how to treat “Web Portal URL“ in clause 7.1. It als
12、o modifies the examples of “Portal URL“ and “Metadata server URL“, changing those into “:/:/“. In clause 10 it also adds a text to show the example on “Metadata server URL“. Moreover, “Preferred Content Guide Discovery record Location“ is changed into “Preferred Content Guide Discovery record“ in cl
13、auses 10.1 and 10.2, and its example has been changed to a Boolean value. Relevant elements/attributes in Appendix II are also changed. This edition of the Recommendation also adds a new service type, “Widget service“, to Table 7.1-4. History Edition Recommendation Approval Study Group Unique ID* 1.

16、.1002/1000/11830-en. ii Rec. ITU-T H.770 (04/2015) 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 (ITU-T) is a pe
17、rmanent 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 four years, estab
18、lishes 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, the necessary sta
19、ndards 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. However, the Re
20、commendation 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 negative equivalent
21、s 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 RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed
22、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 Recommendation, ITU had not r
23、eceived 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:/www.itu.int/ITU-T
