摘要

本文提出了一种采用图像降阶器和自适应梳状滤波器的集成视频解码器的设计。它接受来自各种视频源的多标准视频信号，并根据CCIR建议生成数字化视频数据。图像缩小缩放器根据缩放比例减小原始图像的大小。自适应梳状滤波器去除点爬行噪声和挂点噪声。因此，它提供了解码器的改进性能。该解码器采用0.65 /spl μ m CMOS工艺制作。

Improved performance of video decoder using down scaler and adaptive comb filter

This paper presents the design of an integrated video decoder using image down scaler and adaptive comb filter. It accepts multistandard video signals from various video sources and produces digitized video data based on CCIR recommendations. The image down scaler reduces the size of the original image based on the scaling ratio. The adaptive comb filter removes dot crawl noise and hanging dot noise. Thereby, it provides improved performance of the decoder. The decoder was fabricated by using the 0.65 /spl mu/m CMOS process.
