Document Type and Number:
Japanese Patent JP2012528401
Kind Code:
A
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. Copy management information of the usage protected frame-based work is also accessed. 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.
