Editing Functions and Copy Protection Technologies for DVD/HDD Recorders

摘要

Toshiba has proposed a succession of new functions for DVD/HDD combo recorders including an intelligible user interface, a substantial original DVD creation function, and a cooperation function with PCs via LAN, and is playing the role of a leading company in this field. Although the major advantage of a DVD/HDD combo recorder is its editing functions centering on dubbing between HDD and DVD, a structure for protecting copyright is also indispensable to it. Copy protection technologies such as the content scramble system (CSS), content protection for recordable media (CPRM), copy generation management system (CGMS), and analog protection system (APS) are now incorporated in DVD/HDD combo recorders.
