Abstract

A system and method of secure copy and / or playback control of a usage protected frame-based work is disclosed. The method includes accessing serial copy management system information for the usage protected frame-based work. In addition, the method validates the serial copy management system information.

In so doing, the copy management information is utilized to determine if a secure copy / playback application is authorized to generate a copy of the usage protected frame-based work. Thus the copy management information acts as a technological measure which "effectively controls access to a work" by requiring the application of information, with the authority of the copyright owner, to gain access to the work.
