ABSTRACT:
A control system for use with recording apparatus enables the recording of programs simultaneously desired by a user and authorized by a program provider, typically a broadcaster. The broadcaster attaches a code signal to each program segment which the user's control system recognizes. The control system contains a second code indicative of a preselected program and of authorization to record the program. When the codes correspond the control system activates the user's recorder to record the desired program.
