Viewdata is a generic name for a system that links people to computer-based data through an adapted TV set and the telephone. It is expensive; information providers can spend hundreds of thousands of pounds a year on information frames that still have limited use. In Britain the main system is called Prestel. Pauline Drummond examines its relevance for the health service, particularly in the light of recent experiments.
可视数据是一种系统的通用名称，该系统通过适配的电视机和电话将人们与基于计算机的数据连接起来。它成本高昂；信息提供者每年可能要在用途仍然有限的信息框架上花费数十万英镑。在英国，主要的系统叫做普雷斯泰尔。宝琳·德拉蒙德研究了它对医疗服务的相关性，特别是鉴于最近的实验。
