Abstract
An apparatus and a method for manipulating video, audio, closed-captioned and compressed video packet data embedded in video programming signals includes a video signal processor for embedding data into a broadcast video signal prior to broadcast, the video signal containing at least one of video information, audio information, closed-captioned information and video packet data information. The embedded data is embedded in at least one predetermined line of at least one predetermined frame of the video program signal. An instruction defining a predetermined screening format for at least one of the video information, the audio information, the closed-captioned information and the video packet data information is stored and a circuit is responsive to the embedded data and the stored instruction for reproducing the information in the video signal in a predetermined screening format.
