CB-1型自导象电视放象插播系统是以计算机为主控技术,实现对电视放象远距离的自动控制。它一次可以存储录象带上多段内容的起止位置信息。并以此为依据,在教师讲课时系统能自动、快速地找到任何一段的准确位置,随时插入播放。本文概括地介绍了该系统的基本原理、结构,系统功能、特点和工作方式,以及系统在教学中的作用和应用前景。
CB-1-type self-directed TV broadcast video broadcast system is based on a computer-based control technology to achieve long-distance television broadcast automatic control. It can once store the beginning and ending position information of the multi-section contents of the video tape. And based on this, the system can automatically and quickly find the exact position of any section during the lecture of the teacher, and insert and play at any time. This article gives an overview of the system’s basic principles, structure, system functions, features and working methods, as well as the system’s role in teaching and application prospects.
