图文电视, 电视文字广播
a service delivering written news and information through television, currently replaced by other information services provided on a television network
Teletext is a system that provides text-based information, such as news, weather, and television schedules, on a television screen. It works by transmitting data alongside the regular television broadcast, which can be accessed by viewers using a special remote control. Teletext is often displayed as a series of pages that viewers can navigate through, offering a variety of information in a simple, easy-to-read format. Although it was more popular in the past, it is still used in some countries for providing quick, accessible updates and information on a range of topics.
