Abstract
The author provides an analysis of the current digitization movement of the broadcasting television from the perspective of the information revolution. The author also gives his own viewpoints on various debatable issues in the digital television front, such as the relations between public platform and the paid platform, the unification of the service platform, the wholesale transformation, the import standard, self-developed standard, the unification of the DTV standard, etc. At the end, the author gives a second thought on the significance of the standardization in the digital age. The paper points out that, in the era of the digital revolution, it is the process of the digitization process that brings the progress to the technology and the society rather than the fact of the establishment of the digital standards. It also points out that the way of the standardization process from the industry age cannot fit in with that of the digital technology in the information age. A new way of thinking in the standardization process is needed to meet the change and characteristics of the information society.
