随着数字技术和计算机技术不断深入电视领域.电视技术的全面数字化方向已不可逆转。2000年我台装配了一台十讯道教字分量转播车,在数字化实践的道路上迈出了一大步。本文就数字电视转播车的结构设计、系统构造及设备性能作一介绍。一.数字转播车的优越性就目前电视节目播出和传输而言,离完全数字化还有一段距离,甚至转播车视频输出到微波的信号仍为模拟复合信号,但实践表明,数字转播车与模拟转播车相比具有以下优点:
With the continuous deepening of digital technology and computer technology in the field of television, the full digitization of television technology has become irreversible. In 2000, Taiwan assembled a ten-channel Taoist component car, a big step toward digitalization. This article introduces the structure design, system structure and equipment performance of digital television broadcasting truck. I. The Advantages of Digital OBVs In terms of the current broadcast and transmission of television programs, there is still a long way to go before it is fully digitized. Even the signals of the OBV video output to the microwaves are still analog composite signals. However, practice shows that digital broadcast vehicles and Compared to analog truck has the following advantages:
