五、电视广播及其设备实现电视图象的传送,必须由各种电视设备互相衔接形成一个系统.根据任务的性质,不同电视系统的复杂程度可以有很大的差别,但总的说来每个系统可以分为电视信号的产生设备、传送设备和接收与重现设备三大部分.最简单的是某些工业电视系统.它用一架摄象机来完成电视信号产生,接收与重现则由一架监视器来实现,信号的传送则利用电缆把摄象机与监视器联系起来,如图23(a)所示.复杂一些的系
V. Television Broadcasts and Their Equipment To transmit television images, a variety of television equipment must be connected to each other to form a system. Depending on the nature of the mission, the complexity of different television systems can vary greatly, but in general each A system can be divided into television signal generating equipment, transmitting equipment and receiving and reproducing equipment three parts of the most simple is that some industrial television system.It uses a camera to complete the television signal to generate, receive and reproduce Then by a monitor to achieve, the signal transmission is the use of cables to connect the camera and monitor, as shown in Figure 23 (a) of the complex system
