1.新一代多媒体个人计算机 目前已大量上市的多媒体个人计算机其大部分产品实质上是一种多媒体音像系统,它们把声音、静止图像、活动图像引入到个人计算机中,即把CD-ROM光盘上录制的声、文、图信息通过音效卡和视频卡或专用的音频处理器和视频处理器.输入到计算机中,在计算机上编辑、播放或进行其它处理。 新一代的多媒体个人计算机是多功能化的,它们把电视机、录像机及通信的功能结合进来了。目前已有一些厂家推出了
两年前,美国ATL公司发明了世界上第一台数字超声波机,这种机器能把从病人身体上返回的超声波转变成数字数据,就像用数字把音乐储存在光盘上一样。 用特制的集成电路处理这些数据,就能得到极其清晰的图像。然而,由于超声波在人体内的不规则干扰,图像的清晰度仍
由于多媒体技术的发展与普及,使得人们从繁冗而枯燥的工作中解脱出来,迈进了一个信息处理数字化的新时代。近年来,国内多媒体市场异彩纷呈,不少世界知名的计算机厂商先后推出其独具特色的产品。但在多媒体视频和音频领
