多工单向广播系统(也称多工文字广播系统)是电视领域里的一项新技术,它以高速、紧凑的结构通过正常的电视通道传输文字和图片,由于大规模集成电路的迅速发展,从而使多工单向广播系统在许多国家得到了广泛的应用,本文对该系统将着重论述:1.基本概念。2.多工单向广播系统的应用。3.多工单向广播系统的组成。4.接收设备。5.结论。
Multiplex unidirectional broadcast system (also referred to as multiplexed teletext system) is a new technology in the field of television. It transmits text and pictures through a normal television channel in a high speed and compact structure. Due to the rapid development of large scale integrated circuits , So that multiplex unidirectional broadcast system has been widely used in many countries. This article will focus on the system: 1. Basic concepts. 2. Multiplex one-way broadcast system applications. 3. Multiplex unidirectional broadcast system. Receiving device. 5 Conclusion.
