Abstract: 45,996 A SECURE TELEVISION TRANSMISSION SYSTEM              ABSTRACT OF THE DISCLOSURE          A system for transmitting a secure television image is as disclosed.  At the transmitter each line of the television image is digitized to generate a series of digital numbers representing the complete video line.  The digital numbers representing the picture portion of each scan line are cyclically rotated by a random amount leaving the synchroniz-ing portion unchanged.  The digital numbers are converted to an analog signal which is filtered to generate a composite signal with the picture portion of each line cyclically shifted by a random amount.  At the receiver the signal is digitized and the picture portion of each line is rotated to restore the picture portions of each line to their original position.  The process of rotation is identical to that used at the transmitter except that the amount of rotation must be adjusted to restore all portions of the picture portion of the signal to their original position.  The degree of security resulting from this system depends on the complexity of the system used to determine the random rotation of the individual scan lines.
