Videotheatersystem und Wiedergabevorrichtung dafür

摘要

The video theater system of the present invention has a reproducing apparatus by which picture reproduced from a distribution tape and picture received from a communication satellite are alternatively put on the screen. A scrambled signal transmitted from the communication satellite is converted to a scrambled signal of the same form signal as the scrambled signal reproduced from the distribution tape, thus enabling a common decoder to descramble both the two signals coming from different input routes from each other.
