Abstract An improved method and apparatus for identifying and verifying the proper airing of television broadcast programs is disclosed wherein from the television broad- cast, it can be assured that the programs were televised and received properly and aired at the scheduled time. The invention disclosed utilizes prerecorded or live video programs in which imprinted on a preselected scanning line is a digital encoded identifying number. These video programs with digital encoding are then distributed to network and/or local broadcast stations to be televised with this identification. A plurality of selected aired television channels are then automatically simultaneously monitored at a typical reception site whereby the encoded broadcast is appraised as to the quality of its audio and video, identified and timed, and which information is then stored for a later comparison to that which was actually intended to be aired.
