The emphasis on graphics in computer-based communication first led to higher spatial resolution for computer displays. A more recent trend is the use of higher color resolution. These developments have caused users to expect higher quality renditions of natural scenes and drawn graphics. Higher system speeds have allowed at least limited forms of animation. Together, these abilities begin to approach what many users expect from television. One area where current computer graphics have been less successful in approaching the quality of television images is the rendition of textual information. Since TV is essential ly an analog medium, lines, text, and other such graphic objects generated on it are much less plagued by aliasing than are computer-generated objects produced in a digital medium.
