A method of video compaction based on transmitting only the first instance of each class of digitized patterns is shown to yield a compaction ratio of 16: 1 on a short passage of text from the IEEE SPECTRUM. Refinements to extend the bandwidth reduction to 40: 1 by relatively simple means are proposed but not demonstrated.
