我国数字电视行业标准美国在4年前开播数字电视之后,各国陆续制定的数字电视标准互不兼容。我国的信息产业部从1996年开始便组织主管部门、科研单位及四川长虹电子集团公司制定中国数字电视的行业标准 DVB-C,该项标准预计于1999年底正式启用。目前四川长虹电子集团公司已与多家电视台签订将模拟电视网改造为数字电视网的协议,提供播放中心的系统平台、机顶盒及相关的软硬件设施。经改造的 FHC 信息网可接收200套高清晰度数字电视节目,实现网上购物、点播节目及收发E-mail 等。
China’s Digital TV Industry Standard After the United States began broadcasting digital television four years ago, digital television standards developed by various countries are incompatible with each other. The Ministry of Information Industry of the People’s Republic of China has organized the competent department, scientific research unit and Sichuan Changhong Electronics Group Corporation to formulate the DVB-C industry standard for digital television in China since 1996. This standard is expected to be officially launched at the end of 1999. At present, Sichuan Changhong Electronics Group has signed agreements with several television stations to transform the analog television network into a digital television network, providing the system platform, set-top box and related hardware and software facilities of the broadcasting center. The reconstructed FHC information network can receive 200 sets of high-definition digital TV programs, enabling online shopping, on-demand programs, and sending and receiving E-mail.
