基于FPGA的视频后处理系统
摘要
当前数字电视方兴未艾，但是数字电视的普及需要很长的一个过程。在这个过程中我们既要利用现有的模拟电视系统，同时又要逐步的提高模拟电视的收视质量。目前市场上出现一种基于数字处理方法提高传统模拟电视信号接收质量的电视机，我们称它为数字处理电视。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。它内部集成上述的各种数字处理，是图象质量改善的关键。本文介绍了基于Altera公司的FPGA EP20K1500EBC-1的视频后处理系统的实现过程。这个过程是芯片设计的重要一步，起到验证处理算法效果和验证系统硬件方案可行性的作用。这里将重点描述视频输入接口的设计以及画质增强模块的设计。
Nowday the digital television is springing up soon.But its prevalence needs a long time.In this process, we should not only take full use of the system of traditional analog televion we have,but also improve the quality of the picture of analog television. 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.
The digital process chip of television signal is the core part of the digital process TV set.It integrates all the digital process,and is the key of the improvement of picture quality.In this paper I'll introduce the realization procedure of the video post process system based on the FPGA EP20K1500EBC-1 of Altera Co.And I'll emphasize the design of video input interface and modules of display enhance.
