Abstract:
1. A method for processing a compressed signal of digital video, comprising the steps of: (A) generating a decompressed signal by decompressing said compressed signal of digital video; (B) generating a first signal by spatial filtering said decompressed signal; (C) generating a second signal by comparing an amplitude of said first signal with a first threshold; (D) generating a third signal by modifying said first signal in response to said second signal; and (E) generating a video signal by subtracting said third signal from said decompressed signal to reduce mosquito noise, wherein (i) said third signal is attenuated in response to a programmable constant where said amplitude of said first signal is between said first threshold and a second threshold and (ii) said programmable constant has at most a unity value.
