the wired city refers to a community in which each home has electronic access to a large number of information services.when the connections are optic ,the term fibered city is more accurate.such a community was established in japan under the experimental Hi-OVIS(Hi-gashi-Ikoma Optical visual information system)program.Hi-OVIS also stands for highly interactive Optical visual system.the system consists of a center ,sub-center,and home terminals linked by optic transmission lines.the lines connect computers and video equipment .each home terminal has a TV set,camera,microphone,and keyboard.two-way interactive communications is obtained.Terminals were connected in 158 private homes initially.subscriber services include direct reception of TV programs computers,which provides superior pictures and sound compared to conventional antenna reception.TV programs of a very localized nature are broadcast.For example,programs involving the local police and fire departments and local shopping information are broadcast.A video request service is available whereby the subscriber can request that a particular video cassette be played from a central storage location.Home study courses are available.Still picture giving information about local events,medical facilities,train timetables,and the like,are available.Service such as those described require large bandwidths only available using broadband transmission system.Fiber optic communications provide the needed bandwidth.

互联的城市是指一个这样的社区,即社区中的每个家庭都有电子通道以获得大量的信息服务.当连接是视觉上的时,术语"纤维质城市"更加准确.这样一个社区在日本试验性的Hi-OVIS(Hi-gashi-Ikoma光学视觉信息系统)程序下建立.Hi-OVIS还代表高度交互式的光学视觉系统.该系统由一个中心,分中心,和光学传输线连接的家用终端机组成.
传输线连接电脑和视频设备.每个家用终端机有一个电视机、照相机、麦克风和键盘.双向交互式通信可以获得.终端机最初连接在158户私人房屋上.用户服务包括直接接收电视节目,它提供比传统的天线接收更优越的图象和声音.
地区性质的电视节目就是广播.例如,涉及当地警察和消防部门和地方购物信息的节目就有广播.一个视频请求服务只需用户从中央存储位置请求特定的视频录音带播放就可获得.家庭学习功课也是可获得的.给出当地活动、医疗设施、火车时刻表,以及类似信息的静止图片都是可获得的.如所描述的那些服务需要只有使用宽带传输系统时才可用的高带宽.光纤通信提供所需的带宽.
