Abstract
A market research system is shown for substituting stored television programs for regularly scheduled, broadcast television programs having a particular identification code wherein the substitute television programs may be transmitted via telephone lines to the households of cooperating panelists for storage. The substitute television programs may be stored and/or transmitted to the panelists'"'"'s home in compacted or noncompacted form. In compacted form, a memory stores the first frame of video information for the substitute television program and for subsequent frames, stores only the video information representing a change from the video information stored for a previous frame. In one embodiment, the stored video information represents the difference between each frame and the first frame. In a second embodiment, the video change information represents the differences between each frame and the immediately preceding frame. A system for encoding an identification code in the leading overscan portion of the active line period of a horizontal line of video information is also shown.
