目前,世界各国都正在加紧进行为住宅用户提供交互式视频业务的宽带网络试验.由于这些试验及其小规模的商用均没有充分利用网络新应用和新业务的能力,因而缺乏吸引力.此外,近几年迅速崛起的因特网对当前徘徊不前的宽带视频网络也产生了相当大的冲击作用.文章主要就美国新泽西州多佛城推行的光纤-同轴电缆视频拨号交换网商用中所取得的经验教训作了分析和研究.未来的宽带网络应该朝着在较低的使用价格上综合视频拨号网和因特网各种能力的方向努力.当前需要新型的超越电缆电视和影视点播范围的端对端应用,以重新唤起用户对住宅宽带网络的商用兴趣.
At present, all countries in the world are stepping up the trial of broadband network for providing interactive video services to residential users, which are not attractive because these experiments and their small-scale commercial applications do not fully utilize the capabilities of new applications and services on the network. In addition, The rapid rise of the Internet in recent years has also had a considerable impact on the current stagnant broadband video network.This article mainly focuses on the commercial implementation of optical fiber-coaxial cable video dial-up switching network implemented in Dover, New Jersey, USA Lessons learned and analysis of the future broadband network should be toward the use of lower prices on the integrated dial-up network and the Internet a variety of capabilities in the direction of the current need for a new cable television and beyond the scope of video-on-demand Application to rekindle the user’s commercial interest in residential broadband networks.
