¿µ¹®³»¿ë¿ä¾à In the standard, based on the basic scenario that content is delivered from the CAS protection system to the DRM protection system through CAS-DRM interfaces, information required for interoperability procedures is defined and protocols describing interfacing processes between CAS and DRM are specified. The standard describes interfacing processes between CAS and DRM through authentication, negotiation and transmission processes between CAS and DRM, and also interfacing information named CADMI and interfacing protocol named CADII. In addition, protocol message schema and packet formats for interfacing protocols are handled.
