Abstract
The Video Response System (VRS) with which the Nippon Telegraph and Telephone Public Corporation (NTT) is now experimenting is a public visual information service using home TV sets as described by Nakajima (1977), The VRS stores visual information in a large capacity video store. The stored video information is converted into a TV signal by using a video codec and is temporarily stored in the video frame memory (Figure 1). The TV signal is read out of the video frame memory at a rate of 30 frames/sec and is transmitted to a subscriber’s video adapter through a video transmission line. Among the most important factors in the VRS is the video store and the visual information stored therein.
