随着社会经济的发展和人类文明程度的提高,电子影音领域的高新技术正以越来越快的速度向我们走来。 纵观影音产品的发展,我们可以看到影音技术由模拟向数字技术过渡的轨迹,这一转变为电子家电影音产品的设计带来产品概念的根本性的变化:在少年时代沉迷的采用模拟技术的黑胶唱片留声机则被采用数字技术的CD播放机所取代;采用模拟技术卡座录放机则被采用数字技巧的磁光碟播放机(MD)机取而代之;影像录放机采用模拟枝术,而替代的VCD、S—VCD及DVD机更采用先进的数字压缩技术。这些以数字技术为基础开发出的产品具备质量高、失真少、原音真实感强、操作及携带方便等特点,能够充分满足消费者对高质素生活需求。
With the development of social economy and the improvement of human civilization, high and new technology in the field of electronic audio and video is approaching us at a faster and faster speed. Looking at the development of audio and video products, we can see the trajectory of the transition from analog to digital technology in video and audio technology. This change has brought about fundamental changes in the product concept for the design of electronic home audio products: the use of analog technology in the teenage years. The vinyl record phonograph was replaced by a digital technology CD player; the analog technology deck recorder was replaced by a digital-tagged magneto-optical disc player (MD) machine; the video recorder used an analog stick instead The VCD, S-VCD and DVD players use advanced digital compression technology. These products developed on the basis of digital technology are characterized by high quality, low distortion, strong realism, and ease of operation and portability, which can fully satisfy consumer demand for high quality of life.
