Abstract
The disclosed technology provides a system and a method for adaptive MPEG noise reduction. In particular, the disclosed technology provides a system and a method for reducing blocking artifacts and mosquito noise in an MPEG video signal. An overall MPEG noise detector may be used to determine the presence of noise in one or more frames of a video signal. When a sufficient amount of noise is detected in the one or more frames of the video signal, portions of the video signal that contain noise may be located and filtered to reduce the amount of noise present in the video signal.
