A method for processing a compressed signal of digital video is disclosed. The method generally includes the steps of (A) generating a decompressed signal by decompressing the compressed signal of digital video, (B) generating a filtered signal by spatial filtering the decompressed signal, wherein the spatial filtering is arranged to reduce mosquito noise within the decompressed signal and (C) generating a video signal by adding synchronization information to the filtered signal, the synchronization information being suitable for synchronizing a video display to the filtered signal.
