The cable television industry goes to great lengths to protect its programs from theft. Theft most often occurs when consumers are able to receive content over cable channels for which they have not paid in their subscription account. To block these signals, cable television firms encrypt or scramble their signals so that the subscriber receives only the services for which they have paid. Occasionally, some scrambling techniques employed by cable companies do not block the entire audio and video signals. “Signal bleed” occurs when consumers are able to view such inadequately blocked broadcast material. Signal bleed may cause concern for parents because it may permit children in homes with a cable subscription to view programming that contains objectionable material.
