Abstract
The ability to use a Picturephone® station set to display computer generated information will be provided as an additional feature of Picturephone service. The basic element in providing computer-access service is the display data set, which acts as the interface between the computer and the Picturephone station, converting Touch-Tone® multifrequency signals from the Picturephone station into digital characters for the computer and converting the computer output into a video signal for the station. The operation of the display data set and the influence of the Picturephone network characteristics on its design are described in this article.
