摘要
在MPEG-2中已制定了HDTV图像的国际标准,工业发达国家正在研制HDTV产品。但对于 HDTV信号的三维频谱分析尚未见学者考虑。本文在对HDTV亮度二维频谱分析的基础上,推导出HDTV亮度信号三维频谱特性并对其进行了数学建模。
International standard on HDTY pictures has been worked out in MPEG-2,and developed industrial countries are developing HDTV products. Howeverport on three dimensional analysis of the spectrum of HDTV signals is not available yet. Based on two dimensional analysis of the spectrum of HDTV luminance signals and after his careful study.the author derives three dimensional characteristices of the spectrum of HDTV luminance signals and builds up its mathematic model.
