8、U-T Recommendations. Rec. ITU-T H.751 (03/2013) i Recommendation ITU-T H.751 Metadata for rights information interoperability in IPTV services Summary Recommendation ITU-T H.751 defines the common semantics and core elements of rights information interoperability (RII) for Internet Protocol televisi
9、on (IPTV) systems and/or equipment that allow multimedia content to be legally used across different platforms. The rights information includes rights- and security-related metadata that is described in Recommendation ITU-T H.750. This Recommendation describes rights-related information such as cont
10、ent ID, permission issuer ID and permission receiver ID, which are used to bridge between rights-related metadata. It should be noted, however, that rights management and content protection technology are beyond the scope of this Recommendation. This Recommendation is technically aligned with the sp
11、ecification in IEC 62698, Multimedia home server systems Rights information interoperability for IPTV. History Edition Recommendation Approval Study Group 1.0 ITU-T H.751 2013-03-16 16 Keywords Metadata, permission, rights information. ii Rec. ITU-T H.751 (03/2013) FOREWORD The International Telecom
12、munication 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 permanent organ of ITU. ITU-T is responsible for studying technical, operating and tari
13、ff 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, establishes the topics for study by the ITU-T study groups which, in turn, produce Recomme
14、ndations 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 standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommend
15、ation, 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 Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperabil
16、ity 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 equivalents are used to express requirements. The use of such words does not suggest that compl
17、iance 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 use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity
18、 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 received notice of intellectual property, protected by patents, which may be required
19、 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/ipr/.

ITU-T H.751 (03/2013) 1 Recommendation ITU-T H.751 Metadata for rights information interoperability in IPTV services 1 Scope This Recommendation gives the high-level specification of the metadata for rights information interoperability, including representation of the minimum req
30、uired elements. The rights information interoperability (RII) metadata provide descriptive and contextual classification for representing rights information using the permission framework. RII is concerned with finding the greatest common denominators in rights expressions that include the minimum r
31、equired components when trying to implement the mutual use of rights information. This Recommendation defines the common semantics and core elements of rights information interoperability for IPTV systems and/or equipment that require multimedia content to be legally used across different platforms.
32、 The rights information includes rights- and security-related metadata that is described in ITU-T H.750. Rights-related information, such as content ID, permission issuer ID and permission receiver ID, which is used to bridge between rights-related metadata, is considered in this Recommendation. It
33、should be noted, however, that rights management and content protection technology are beyond the scope of this Recommendation. This Recommendation is technically aligned with the specification in IEC 62698. 2 References The following ITU-T Recommendations and other references contain provisions whi
34、ch, through reference in this text, constitute provisions 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 a
