Abstract :
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 μm CMOS process
