Because television sets are often used in areas where the reception conditions are less than optimal, the inclusion of a noise reduction filter in the receiver adds an attractive feature. A new IC 1) for economy TV 2-D spatial noise filtering has been designed and is described in this paper. It includes a novel circuit for noise-level estimation for optimal filtering under varying reception conditions. When cascaded with commonly-available motion-adaptive temporal noise filters, a high quality 3-D concept for high-end TV results. The average improvement in noise level is some 3 dB in stand-alone operation, and some 6 dB when cascaded.
