With high development of information technology , hdtv ( high definition tv ) gradually replaces analog television . during this transition stage , stb ( set top box ) holds the balance 随着信息技术的高度发展，高清晰度数字电视将逐步取代模拟电视，在模拟电视向数字电视的过渡阶段，机顶盒起了举足轻重的作用。
Liquid crystal projection technology is one of the important technology which can provide us large size and high - definition image . digital projection technology is coming to be a new subject 光学液晶投影技术是实现大屏幕，高分辨率，高清晰度现实的主要技术手段，光学数字投影技术逐步形成了一个学科方向。
With the development of high - definition tv ( hdtv ) technology , it is expected that large size and high - definition image should be provided . traditional crt technology can hardly do it 随着高清晰度数字电视( hdtv )技术的发展，人们对大屏幕图像显示的清晰度要求越来越高，这种要求是传统的crt显示技术难以达到的。
The term is industry jargon for attempting to simulate real - time interactions between people in different locations using high - definition monitors , highly sensitive audio equipment and integrated networking gear 他们的口号是：试图通过高清晰度监视器、高灵敏度音像设备和集成网络装置，实现位于各方与会人员实时交流。
With the development of the communication technology in recent years , the high resolusion digital video is used more and more widely , so the research on more efficient video coding technology has been a hot point 随着近年来通讯技术的发展,高清晰度视频的应用越来越广泛,因此高效的视频压缩技术成为当今的研究热点之一。
On the other hand , however , the potential market for chinese digital and hdtv is maturing . this is the great opportunity for cpt enterprises , to upgrade their production and strive for new areas of growth 但另一方面，中国数字化、高清晰度彩色电视机潜在市场的崛起，又为彩管企业提升产品等级、争取新的增长点带来了机遇。
As a result of that we are being forced into moving into the digital age and going into the high definition broadcasting and high definition cameras . you cannot have part digital here and part analog over there 于是，我们被逼进入数码时代，使用高清晰度的播放，高清晰度的摄录机底线是，我们必须完全数码化，不可能只改变一部份，必须整体改变。
