    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.
