Abstract
The invention provides a non-intrusive method and apparatus for encoding a digitized raster display signal which may then be transmitted from a host computer system to a remote display across a communications link. Hash codes are used to detect persistent blocks of pixels in a real-time digital raster signal generated by the host computer. A progressive encoding and transmission sequence is then initiated, using parameters such as bandwidth availability and build quality requirements to determine suitable encoding methods and build levels.
