Abstract
Abstract Methods and apparatus for video information bandwidth compression arrange the video information in image fields and subfields and provide for the subfields a system of coefficients having a first coefficient indicative of average subfield luminance as to any given subfield and including a selected number of further coefficients indicative of spatial content of the particular subfield. The first and further coefficients are updated with the first coefficient being updated for each subfield as to each utilized field and the further coefficients being updated less frequently than the first coefficient. The subject invention is also applicable to bandwidth compression of recurring information other than video signals.
