The thesis researchs the basic theory of digital hdtv test pattern signal generating system and its realization based on soc ( system on chip ) 论文研究了数字高清晰度电视测试图案信号发生系统基本原理及其基于片上系统( soc , systemonchip )的具体实现。
Viewable test pattern signal provides an intuitionistic and convenient evaluating method , therefore , hdtv test pattern signal generating system become a hot research of world today 可视化的测试图案信号提供了直观、快捷的评测方法,因此,高清晰度电视测试图案信号发生系统成为当今世界的热门研究课题。
The system generates 18 kinds of worldwide used hdtv test pattern signals supported by smpte 274m standard , and also provides ypbpr , rgb video outputs both in digit and analog and the output interfaces of itu - r bt . 1120 - 2 / gy / t157 - 2000 studio hdtv digital video signal interface standard 该系统生成了符合smpte274m国际标准的18种普遍采用的hdtv测试图案信号。它提供ypbpr 、 rgb两种视频数字输出与模拟输出,其接口符合itu - rbt . 1120 - 2 / gy / t157 - 2000演播室高清晰度数字视频信号接口标准。
