In certain embodiments, a method of partially dual encrypting a digital video signal involves examining unencrypted packets of data in the digital video signal to identify a specified packet type. The specified packet type includes packets occurring in a star pattern approximately situated at approximately a center of an image; encrypting packets identified as being of the specified packet type using a first encryption method to produce first encrypted packets; encrypting the packets identified as being of the specified packet type using a second encryption method to produce second encrypted packets; and replacing the unencrypted packets of the specified packet type with the first encrypted packets and the second encrypted packets in the digital video signal to produce a partially dual encrypted video signal. This abstract should not be considered limiting since embodiments consistent with the present invention may involve more, different or fewer elements.
