scope:

The objective of this Recommendation is to specify a service model and architecture for downloadable mobile multi-CA/DRM (DM) solutions for delivering CA/DRM client software to a secondary device [ITU-T J.1010], [ITU-T J.1011] such as a smart phone, tablet or laptop PC connected to a primary CPE [ITU-T J.1011] such as a set-top box for cable television services. Note that the terminology of "secondary CPE" is used in [ITU-T J.1011] instead of "secondary device" with the same meaning. The use cases, requirements and architecture of a downloadable multi- CA/DRM service are specified through [ITU-T J.1010] and [ITU-T J.1011] under the name of "exchangeable CA/DRM solutions". The downloadable multi-CA/DRM service is part of a bigger family of services named the renewable CA system (RCAS), which are described in the Recommendations [b-ITU-T J.1001], [b-ITU-T J.1002], [b-ITU-T J.1003] and [b-ITU-T J.1004]. Note that the use case related to this Recommendation is described in Annex A of [ITU-T J.1010].

A reference service model and architecture will include entities such as MVPD, a third-party authorization centre and secondary devices which are necessary for providing downloadable service of CA/DRM client software. This Recommendation also specifies the service operation protocol among the entities that are part of the reference service model and architecture.
