20世纪80年代,欧洲几个电视技术较为先进的国家,如德国、法国、英国,都开始研究数字电视技术,数字电视由于其高效、方便及技术先进而迅速在全球范围内并得到广泛的推广。随着新技术的发展,铺设光纤和网络改造的成本降低,数字技术的运用使高清晰电视所要求的带宽相对降低,运用成熟的IP技术可以在使用网络的同时还能够提供互联网服务,即实现了“三网合一”技术。文章在介绍数字电视的概况的基础上,详细分析了三网合一技术的深刻内涵,并对我国实现三网合一技术提出了发展建议。
In the 1980s, several countries with advanced television technologies in Europe, such as Germany, France and the United Kingdom, started to study digital television technology. Due to its high efficiency, convenience and advanced technology, digital television has rapidly become a worldwide promotion and widely promoted . With the development of new technologies, the cost of laying optical fiber and network transformation is reduced. The use of digital technologies reduces the bandwidth required for high-definition television. By using mature IP technology, Internet services can be provided while using the network, that is, The “triple play ” technology. Based on the introduction of the general situation of digital television, the article analyzes the profound connotation of triple play technology in detail and puts forward some suggestions for the realization of triple play technology in our country.
