As the algorithm proposed in this dissertation is designed for ic , the following part of the dissertation introduce two leading algorithm that has been implemented in ic : philips ' s motion compensated de - interlacing algorithm and faroudja ' s edge - based de - interlacing algorithm 论文提出的算法最终是面向芯片实现的，因此论文接下来主要介绍了业界具有领先水平的两款视频后处理芯片中的去隔行算法：飞利浦的基于运动补偿的方法和faroudja的基于边沿检测的方法。
When picture adaptive frame / field ( paff ) is utilized to interlaced sequences , two fields can be combined into one frame , which is encoded in frame coding ; besides , they can also be encoded in field coding separately . adopting field or frame coding can be determined by coding performance adaptively 图像级帧场自适应( paff )技术在处理隔行序列时,可将两场合成一帧,按照帧编码方式进行,也可以将其作为两场分别编码;采用帧或场编码可根据编码效果自适应选择。
The author first introduces several problems that interlaced video suffers from : the basic vertical resolution is inadequate for displaying filmlike quality , and interlaced video generates visual artifacts , including edge flicker , shimmering , and diagonal jaggedness . then the author reviews some representative de - interlacing algorithm that has been proposed 论文首先介绍了隔行电视存在的若干个缺陷：对于显示类似于电影质量的图像而言，隔行电视的基本垂直分辨率是不够的；隔行电视还会产生许多视觉虚像，例如边沿闪烁、爬行和锯齿等，接着简单回顾了学术界已经提出的经典的去隔行技术。
Employing the interlaced scanning , current tv system can compress the frequency band of tv signal effectively and facilitate transmission . but this method reduces the scanning lines of pictures and the frequency of the field . it leads the pictures displayed on tv to have such disadvantages as large area flicker , edge flicker , interlace flicker , raster visibility and creeping line etc . to satisfy people " s vision feeling better , the big - screen , multi - function and high quality tv - set have been made great progress 现行的广播电视系统由于采用隔行扫描方式，从而有效地压缩了电视信号的频带，有利于传输；但由于这种方式使得图像的扫描行数少，场频低，导致了重显的电视图像有大面积闪烁、边缘闪烁、行间闪烁、行结构可见及行爬行等。
Researched four technology of structure conversion about digital video , de - interlaced , frame ratio down or up , row ration down or up , the width and high transforming , implemented lots of corresponding arithmetic of four techniques , motion compensate structure conversion method based on the motion estimating improved the image sequence definition and liquidity degree 4研究了数字视频结构变换的四种技术：去隔行技术，变频技术，行频转换技术，宽高比变换技术。实验验证了大量的相关算法，其中基于运动估计的运动补偿结构转换方法，清晰度和流畅度得到了很大的提高。
The dvd recent three stars face toes the chinese consumer , releases the world the section 1 to make to order for high and clear degree television to broadcast the , namely three stars the dvd - hd938 , it can pass the general port to realize the pal system the type bottom to is every other line with the line painting quality for scanning outputting 576 is 576 p , can emerging the export surplus commonly even pal system type line scanning ; but the adoption image strengthen the technique to ask for help the dvi port to can more realizes 1080 is 720s p exportation result . more important , pass to see the format conversion of the , and the can of high and clear degree television is produceding can attain of distinguish the rate . 1080 is 720 p 慧聪影音商务网最近三星面向中国消费者，推出了世界第一款为高清晰度电视定制的dvd播放器，即三星dvd - hd938 ,它可以通过一般端口实现pal制式下隔行和逐行扫描输出576i 576p ，能够展现出超过普通甚至pal制式逐行扫描的画质而采用影像增强技术借助dvi端口更可以实现1080i 720p输出效果。更重要的是，通过视频的格式转换，可以产生高清晰度电视所能达到的分辨率1080i 720p 。
This dissertation mainly focuses on the key technology in the digital video post - processing ic - de - interlacing . in the dissertation , the author proposes our own motion compensated de - interlacing algorithm , which has been applied for four patents and our own edge - based motion adaptive de - interlacing algorithm , which is being applied for patents 论文主要针对后处理芯片中的关键技术?去隔行，进行了深入的研究：提出了自有的运动补偿去隔行算法，该算法已经申报4项国家发明专利；自有的基于边沿的运动自适应去隔行算法，该算法的专利目前正在申报中。
At present a new kind of tv set appears in the market . it " s based on the digital process technology , and we call it digital process tv set . it use various of the diagital methods to process the interlace , low field _ rate signal , include the deinterlace , field _ rate conversion and the methods of display enhance 他的核心是利用各种数字的方法对隔行低场频的模拟电视信号进行去隔行、提高帧频、以及进行降噪和各种画质增强的处理，极大的改善了画面的质量。数字处理电视的核心是电视信号数字处理芯片。
