Abstract
Raster segment commands are generated by a delta encoder and are encoded for raster segments detected to have moved in the current frame with respect to a location of the raster segment in a previous frame. Raster segment motion commands are stored in a queue and, when written, copy a raster segment into the current frame from a previous payload or cache. When written from the queue to a payload, raster segment motion commands are applied to a copy of the current frame maintained at the server using a copy of the previous payload sent. When copying a raster segment from a raster segment cache, a raster segment cache command retrieves identified raster segment data from the raster segment cache and copies the raster segment into a particular location in the current frame at the client. The raster segment commands are sent to a client via a payload to copy a raster segment from a previous payload into the current frame at the client or from a raster segment cache to the current frame.
