1000行或更高清晰度电视系统已出现几十年了,但是它需要相应宽的频带,除了短距离以外限制了它的应用。一个解决办法就是形成窄带信号以传送单帧视频信号。在接收端由数字存储器通过扫描变换来重现。本文描述的系统,收集了两种传输高清晰度慢扫描电视信号的方法:第一种使用常规的1000行电路摄象机 It has been decades since the 1000-line or higher definition television system, but it needs a correspondingly wide frequency band that limits its use beyond short distances. One solution is to form a narrow-band signal to transmit a single-frame video signal. At the receiving end, digital memories are reproduced by scanning transformations. The system described herein collects two methods for transmitting high-definition, slow-scan television signals: The first uses a conventional 1000 line circuit camera
