摘要
A method for determining a noise value that corresponds to the noise in a signal the signal containing identical signal parts in the noise free signal. Noise values that correspond to the noise in a signal can be used to control noise reduction filters as well as other digital improvement circuits, in particular picture improvement circuits. This is of particular interest for digital signal processing in modern television receivers. The invention helps to use picture improvement algorithms that exist in modern digital television receivers more efficiently.
