基于WST(WORLD SYSTEM TELETEXT)制的中文图文电视系统已研制成功。这项科研成果是由广播电影电视部广播科学研究所、飞利浦公司元件部和VG电子公司共同开发研制成功的。WST制式是国际上通用方式用户图文电视——即把数字信息编码后,作为电视信号的一部分来传送,它可以在一专门的家用接收机上进行解码,并显示出本文信息和图像。图文电视在国外发达国家已正式开播应用,但多属西文方式,汉字系统的WST制图文电视解码器还处于研制、开发完善之中。该项目研制工作是从1988年初开始的,利用双方
The Chinese teletext system based on WST (WORLD SYSTEM TELETEXT) has been successfully developed. This research result was successfully developed by the Broadcasting Institute of Radio, Film and Television, Philips Components and VG Electronics. The WST system is the internationally accepted user teletext - the digital information encoded and transmitted as part of a television signal that can be decoded at a dedicated home receiver and displayed in this document. Teletext has officially started applications in developed countries, but most of them are in Western style. The Chinese system of WST teletext decoder is still under development and being developed. The research and development project started from early 1988, making use of both parties
