scope:

This international standard defines the Permission Code, a set of Permission related information in short code form, primarily intended for Home Server systems. The Permission Code is comprised of a Common ID System (Content ID, Issuer ID, Receiver ID, Device ID etc.) and a Narrowly-Defined Permission Code.
The Common ID System is used to systematically identify every entity, Device, and Content that would be involved in the course of digitally distributing Content. The Permission Code can express various sets of Permission information and Permission conditions necessary for Content transmission in a remarkably short code form. The Permission Code is not defined from a technical perspective, but rather on the basis of Permission information that rights holders actually employ in the field. Even after, the Permission Code is recognized for its technical effectiveness with respect to digital distribution of Content.
