It will have an impact on the whole movie and television system, every field of the business as well as IT industry and the whole society. Characterized by the articulation of its audio frequency, the fidility of its visual frequency and its capability of offering multi_channelled progroms, digital television will inevitably replace analog television. Besides, digital television also makes it possible that the users can request programs and interact with one another, which will be a new value_added business. The departments concerned in China have made the strategies which will be taken in "three steps" concerning the development of digital television.

It is believed that these problems yet to be solved are only the darkness before daybreak and that the number of digital television users will soar soon.更多还原
