1953年美国国家电视制式委员会推出NTSC制,晚几年欧洲相继推出PAL制和SECAM制彩电制式,世界彩色电视机经历了近45年的发展。45年中,除了已被世界各国普遍接受的三大彩电制式本身没有任何原则性变动外,用来接收这三种制式彩电信号的电视接收机却发生着翻开覆地的变化,大体经历了以下几个阶段: 1.电子管阶段 2.半导体阶段 3.集成电路阶段 4.电脑、遥控阶段 5.全制式大屏幕阶段每一个阶段的跃升,总是由一类器件或一门技术的发展来推动的。那么从电脑、遥控跃升到全制式大屏幕阶段又是靠什么来推动的呢?全制式大屏幕彩电在功能上、电路上、所有元器件等诸方面使用了哪些新技术?诸如此类的问题想必读者是十分关注的。本刊有志于让读者对这方面的技术内容有
In 1953, the National Television System Committee of the United States introduced the NTSC system. In the later years, Europe has successively introduced PAL system and SECAM system. The world color television system has experienced nearly 45 years of development. In the past 45 years, apart from the fact that the three major TV standards, which have been universally accepted by all over the world, do not have any principle change in themselves, the television receivers used to receive the three types of standard TV signals have undergone a turnaround and have generally experienced The following stages: 1. Tube stage 2. Semiconductor stage 3. Integrated circuit stage 4. Computer, remote control stage 5. Full-scale large-screen stage Each stage of the jump, always by a class of devices or a technology development Promote. So from the computer, remote control jumped to full-scale large-screen stage is to rely on what to promote it? Full-size large-screen color TV in function, the circuit, all the components and other aspects of the use of new technologies? Such questions must have readers Is very concerned about. The magazine interested in allowing readers to have technical content in this area
