Title:
DYNAMIC COPY PROTECTION OF OPTICAL MEDIA
Document Type and Number:
WIPO Patent Application WO2003046680
Kind Code:
A3
Abstract:
A method for copy protection includes receiving data in a recording module (62) representing content to be recorded on a recording medium (60), the data including an indication that the content is to be protected from unauthorized copying. Responsive to the indication, the recording module signals a protection module (64) to initiate a protection protocol in synchronization with the recording module. The protection module generates control information, so as to prevent the unauthorized copying of the content that is to be protected, and conveys the control information to the recording module, in accordance with the protocol. The recording module combines the control information with the data representing the content in the recording module, for recording on the recording medium.
