基于Matlab的数字电视原理实验教学研究

针对电视原理实验教学的需求，以演示实验为主，由于学生无法了解数字电视信号处理的细节与算法，为此笔者基于Matlab 软件开发建设了数字电视原理实验教学平台。根据数字电视原理教学内容设计了6 个实验模块，每个模块包含不同的实验项目，涵盖了数字电视信号的产生、处理和压缩编码预测等内容。给出了实验模块的设计原则，并依次阐述了模块的实验原理及内容，以具体实验模块的操作为例讲解了平台的使用方法。实际应用表明，数字电视实验教学平台满足了课程的实验教学需求，取得了较好的教学效果。

Digital Television Principle Experimental Teaching Platform Based on Matlab

In order to meet the needs of the experimental teaching of television theory，the digital television principle experiment teaching platform based on Matlab software is developed． According to the teaching content of digital television theory． Six experimental modules are designed，each module contains different experimental projects，covering the important aspects of digital television signal generation，processing and compression coding prediction． The design principles of the experimental module are given，and the experimental principle and content of the module are introduced． The application of the specific experimental module is taken as an example to explain the use of the platform． The practical application shows that the digital television experiment teaching platform meets the demand of experimental teaching and has achieved good teaching effect．
