There are a variety of emerging technologies which will facilitate the incorporation of video into the work station environment. These technologies, whether analog or digital, very often require the addition of special purpose hardware to be added to the work station or personal computer. We have been investigating algorithms for the display and integration of video image sequences into a PC using an off-the-shelf graphics adapter. The techniques we employ are not as powerful as those taking advantage of special purpose hardware. In particular, no provisions are made for either real-time capture or full screen motion. However, by providing the simultaneous display of multiple, scalable, moving movies, "multi-media" applications which use preprocessed, window-sized video sequences can be designed. In this paper we describe both techniques for image reduction and coding and various strategies for decoding, playing, and smoothly moving video image sequences.
