一个时期以来,图文电视作为一种新兴的信息媒介在我国脱颖而出。继中央电视台正式播出图文电视节目后,北京、浙江、山东、云南、贵州、四川、河南等十多家省市电视台也陆续开展了图文电视播出业务,并且通过卫星覆盖全国。现在,凡是能正常收看电视节目的地方,用加装了图文电视解码器的电视机都可以收看图文电视信息。 For a period of time, Teletext has emerged as a new information medium in our country. Following the official broadcast of teletext by CCTV, more than 10 provincial and municipal TV stations in Beijing, Zhejiang, Shandong, Yunnan, Guizhou, Sichuan and Henan also successively launched the teletext service and covered the whole country with satellites. Now, where normal television programs can be watched, teletext messages can be viewed on televisions equipped with teletext decoders.
