ABSTRACT OF THE DISCLOSURE A scrambled television program is received and recorded in a scrambled fashion automatically in a video tape recorder by detecting program code signals placed in vertical blanking intervals of ten fields preceding the commencement of the scrambled program signal and upon sensing such program code signals the video tape recorder is activated to record the scrambled television program. A stop code signal is arranged following the coded television program and is detected for stopping operation of the video recorder, so that the scrambled program is recorded without requiring the manual setting of automatic timers or the like. In addition to the program code, a key code, and scene change signals are transmitted and these are used to produce a descramble pattern to descramble the television program when it is reproduced by the video tape recorder. By placing the key code after the television program, the entire program must be recorded in scrambled form before it can be reproduced and descrambled for viewing, thereby automatically recording the scrambled program without requiring a timer.
