Abstract
A system and method of determining the copy protection features of a program, and notifying a potential user of the program of these features, is provided. The copy protection features of the program first are analyzed. On the basis of this analysis, a message such as 'this program cannot be recorded with IEEE1394, optical digital audio' is displayed to the user. By displaying such a message, the user can easily recognize that copy protection is applied to the program and that, for example, the program can be recorded (picture-recorded) in an analog style but cannot be digitally recorded. Accordingly, the user is easily made aware of the copy protection features of the program before using or purchasing the program.
