| Chinese tri-net convergence has developed to the 18th year. Throughout the convergence process of seventeen years, it’s actually a road with competing. The technical, economic and political levels’revolution caused by the tri-net convergence, promote the development of telecommunication, broadcasting and Internet their own. Two-way access of their business breaks their original boundaries, the definition of each business began to blur. As the sign business, this characteristic to TV media is particularly obviously.This article will regard the technical, economic and political factors in each time node of tri-net convergence as the research background, combined with definition of mass communication by Guo Qingguang, to analysis TV media’s technical, industry structure, content and role three factors’dynamic changes in the convergent process, and this article which will be discussed is divided into five chapters.The first chapter is introduction. It’s combined with the background, the theoretical basis, the literature review and core concept definition.The second chapter is divided the tri-net convergence into Three Times which consult with CASS researcher Jiang Fei. By analysis this Times from technical, economical and politic level to achieve the true reason of the acceleration of tri-net convergence.The third chapter is discussing the TV media technical level’s change during with the tri-net convergence promotion. Based on the definition of the TV media, it combined with TV technology, TV production technology and signal transition technology. With the convergence advancing, telecom, broadcast and Internet progressive realized the two-way access. The characteristics of intelligent and ubiquitous net-access are very obviously.The forth chapter is discussing the changes of the content and role of the TV media. The technical progress by the tri-net convergence has pushed the way of communication advancement, TV media has begun to change to the two-way communication from the one-way, and then some academic put forward "the third age of media". Because of changes in the mode of communication, the TV media’s content has taken forward to the All Category and Fully Participation.The fifth chapter is analysis the TV industries’ changes in the whole media industry in the Three Times. Base of the definition of the industry structure, the article analyzed the reason from the changes of the TV industry in the media industries’ constitute and the proportion of the TV industry and other sub-industry. With the deepening of the tri-net convergence, the boundary between TV industry and other sub-industry is vague, and showing the trend of the whole of the media industry development.With the deepening of the tri-net convergence, fiber broadband network began to access to the thousands of households, and digital TV has replaced the traditional CRT TV, the networks’ ubiquitous access and the realization of content with all media form let the TV media started out originally defined by the mass media scholars. In the age of the communication by ever-present, everywhere, omnipotent, so many professor called the third media age or all media age, TV media will represent the traditional mass communication taking the lead in this new era. The broadband strategy took the tri-net convergence into a new wave of development, because of the situation of the technical, economic, political factor is constantly changing, we need to re-examine and analyze the TV media in this era, in order to tease out TV media’s development trend and the role in the new communication environment. |
