ABSTRACT:
A method is disclosed for reducing the information needed to communicate graphical information of high quality from one point to another in a system which provides codes describing graphical characters to represent portions of an image. Like characters of a standard size which frequently appear in adjacent strings, for example to represent the background of a graphical picture, are replaced with larger characters of carefully selected size having the repetitive pattern of the standard character. Sending larger characters greatly reduces the time and information needed to reproduce a graphical image.
