ITU-T Recommendations

Recommendation ITU-T H.751 defines the common semantics and core elements of rights information interoperability (RII) for Internet Protocol television (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 content 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 specification in IEC 62698, Multimedia home server systems – Rights information interoperability for IPTV.
