This document defines the method for transport of System Renewability Messages. A System Renewability Message (SRM) is a message issued by the administrator of a Content Protection System (CPS) that, when sent to devices that use that CPS, can revoke permission of certain devices or groups of devices to obtain content protected by that CPS.

Annex A provides an insertion model for SRM distribution, and Annex B presents an informative overview of how System Renewability Messages are used |
