    摘要: Systems and methods for authenticating subscribers of video signals are disclosed. In accordance with the various embodiments, a subscriber authentication system includes an encoder coupled to a source of video signals and a source of subscriber data. The encoder generates encoded video signals having at least a portion of the subscriber data encoded in the video signals. An authentication indicating apparatus operable to receive the encoded video signals and to decode the received signals generates an authentication status for the subscriber.

    摘要: A method for modulating a video signal. Frames of a plurality of frames are selected for modulation. A first magnitude alternation pattern is designated for each of a first area of a field of the selected frames. A second magnitude alternation pattern is designated for each of a second area of the field of the selected frames. The intensity of a plurality of pixels of a plurality of scan lines of the field of the selected frames is altered as designated by either the first magnitude alternation pattern or the second magnitude alternation pattern.
