随着数字技术的日趋成熟,以及大规模集成电路的广泛使用,数字化的家用电子产品CD、VCD、DVD、HDTV等等,如同潮水一般,滚滚而来。可以预见,下个世纪的电子产品将是数字化的天下,离开数字化,产品将无法生存。 数字化产品之所以能“走红”,在于有两个突出的优点:一是数字化视音频(设备)系统重放的声像效果远远优于模拟系统,二是数字化产品便于与电脑“接轨”形成多媒体产品。 为了促进国际多边贸易的发展避免形成新的技术壁垒,自80年代以来国际标准化组织(ISO)、国际电工委员会(IEC)和国际电信联盟(ITU)等国
With the maturation of digital technology and the widespread use of large-scale integrated circuits, digital home electronics CDs, VCDs, DVDs, HDTVs, etc., are rolling. It can be foreseen that electronic products in the next century will be the digital world. Without digitalization, products will not survive. The reason why digital products can become popular is that there are two outstanding advantages: First, digital audio and video (device) system replays much better than analog systems; second, digital products are easy to form with computers. Multimedia products. In order to promote the development of international multilateral trade and avoid the formation of new technical barriers, since the 1980s the International Standardization Organization (ISO), the International Electrotechnical Commission (IEC) and the International Telecommunication Union (ITU) and other countries
