计算机和微电子技术的发展导致了数字化信息技术革命。通信、广播电视和视听消费电子产品数字化进程快速发展,使得计算机、通信、广播电视这三个原来分工明确的行业出现融合和会聚现象。1994年因特网商业化获得巨大成功,提供了一种能够将不同类型网络进行无缝连接的有效方法。随着宽带IP技术的发展,在IP网上传输实时业务保证QoS的问题基本得到解决,宽带IP网成为三网融合的结合点。通信业正在进行一场从面向连接、时分复用、电路交换的传统体制转向无连接、统计复用、包交换的新体制的体制革命。人类将进入宽带交互式媒体新时代。三网融合将产生新一代的信息网,它将改变人们的社会、经济、文化、生活方式。因特网经济已经形成,并将对全球经济发展产生重大影响。
The development of computer and microelectronics technology has led to the digital information technology revolution. The rapid development of the digitalization process of communications, radio and television and audio-visual consumer electronic products led to the convergence and convergence of the three industries with clear division of labor such as computers, telecommunications and radio and television. The great success of Internet commercialization in 1994 provided an effective way to seamlessly connect different types of networks. With the development of broadband IP technology, the problem of real-time service guaranteed QoS transmission over IP network has basically been solved. Broadband IP network has become the convergence point of triple play. The telecommunications industry is in the midst of a structural revolution that shifted from the traditional system of connection-oriented, time division multiplexing and circuit-switched to the new system of connectionless, statistical multiplexing and packet switching. Humanity will enter a new era of broadband interactive media. Triple play will generate a new generation of information network, it will change people’s social, economic, cultural, lifestyle. The Internet economy has taken shape and will have a significant impact on the global economic development.
